Description
Method
Technical field of the present invention
Put it briefly, the present invention relates to use tobacco product, such as the correlativity between the existence of cigarette and advanced glycosylation end product (AGEs) (advanced glycosylationendproduct), and relate to diagnosis, treatment and the industrial applications that can help to relate to this observations and relation.More particularly, the present invention itself relates to a kind of like this observations, it is the amount that the consumption of tobacco product can increase AGEs in the body, concomitant circumstances is the harm and the incidence of disease increase of accumulating relevant disease with smoking and AGE, and the present invention relates in the smog of tobacco, tobacco and the extract thereof and the detection of AGEs in the tobacco user body, comprise and detect unwanted excessive AGE level and estimate the tobacco of commercial scale and the material of being fuming.The invention still further relates to AGEs and form the application of inhibitor in various scopes so that treat or prevent unwanted excessive AGE level and the tobacco and the material of being fuming that improve commercial scale.
Background of the present invention
Smoking has obtained proof widely to the illeffects of health.In other situation, with regard to the smoker, this class disease, increase significantly on the incidence of disease and seriousness such as cancer and coronary artery disease, and this class patient is showing significant change aspect lipoprotein distribution and the oxidation LDLs rising equally.In other situation, the incidence of disease and the seriousness of also observing coronary artery disease and dyslipidemia in the patient that advanced glycosylation end product (AGEs) level raises increase, and the consistance of these observationss provides stage for this discovery that constitutes basis of the present invention.
Non-enzyme reaction between glucose and the protein obtained confirming many years, and the biology and the medical consequences of nonenzymatic glycosylation still manifest at present in the molecule detail drawing of these reactions and the body.The nonenzymatic glycosylation of Que Rening takes the form of in the cooked food process and brown pigment occurs the earliest, and this is definite in 1912 by Mei Lade (maillard), and term " brown stain " is used for this Food Chemistry.U.S. rad observe glucose or other reducing sugar spontaneously with contain amino compound, form original schiff bases adduct such as amino acid and reactive polypeptide.This then shrinkage product carries out a series of other spontaneous dehydration, rearrangement and other reactions and forms various types of brown pigment, is called advanced glycosylation end product (or AGEs) at present.
This initial discovery in later several years, studied Maillard reaction the Food Chemistry furniture body and determined and stored and can carry out non-enzymatic browning and the improvement of primitive reaction between as glucose and polypeptied chain through heat treated food, and determine that as a result of protein cross and protein correspondingly show the bioavilability of reduction.In this, determine that the pigment that causes protein glycosylation (or advanced glycation) toffee to manifest also has characteristic absorption spectrum and fluorescent characteristic.
The reducing sugar of the above-mentioned discussion of discovered in recent years and the reaction between the food component are parallel in vivo to be carried out.Therefore, the non-enzyme that adds the original schiff bases that glucose forms by the free amine group on protein is reset and can be formed stable amino, and 1-deoxidation ketose base (ketosyl) adduct is called the Amadori product with this adduct.(parallel reactor that relates to reduction ketose rather than aldose generates the early glycosylation product that is called the Heyns rearrangement product).Proved accumulating of this early stage saccharification adduct and haemoglobin taken place, wherein with the primitive reaction of glucose after, the aminoterminal rearrangement of haemoglobin beta chain forms the haemoglobin modified, is called hemoglobin A
Ic, it is a kind of important marker that is used for the contrast of diabetes glucose clinically.Also taken place with various other body protein, such as the saccharification react of lens crystalline, collagen neuroprotein and low-density lipoprotein and DNA and amino phosphatide.
U.S. rad brown stain process generates the advanced glycosylation product of a large amount of varying numbers, and each in them all presents very low yield.This species diversity makes determining of concrete AGEs and structure determination becomes knotty problem.At United States Patent (USP) 4,665, in 192, from the polypeptide of some browning, such as separating bovine serum albumin(BSA) and the poly-L-Lysine and having discerned fluorescent chromophore 2-(2-furoyl)-4 (5)-2 (furyl)-1H-imidazoles.This has successfully promoted the identification of other subsequently advanced glycosylation end product and has impelled the research of more attempting to understand the chemistry of protein ageing process and discerning related special reaction thing, intermediate product and product, thereby has improved method and the reagent that is used to suppress saccharification.
Recently, confirmed other advanced glycosylation product, such as AFGP (on May 21st, 696,1991 authorized for Farmar etc., United States Patent (USP) 5,017); Pyrraline (Hayase etc., " wearing out of protein: the pyrroles's who forms in the Maillard reaction process in the body of glucose induction immune detection ", " journal of biological chemistry " 263:3758-3764 (1989)), and pentosidine (Sell, D. with Monnier V. " from the structure explanation of the aging cross-linking agent of human body extracellular matrix ", " journal of biological chemistry " 264:21597-21602 (1989)).
A large amount of evidence proofs of having collected are done the basis that as a whole Mei Lade product constitutes various normal and pathogenic activity and the reaction that take place when AGEs accumulates in vivo.This class activity can be directly, for example the chemically reactive result of saccharification product and adduct; Or non-directly, it is by the cell recognition mediation by the saccharification adduct of AGE binding proteins specific or acceptor.
Although the research of the majority of the pathogenic effects that AGE accumulates in the description body concentrates on AGE-protein and the AGE-peptide, but (for example) atheroma that is reflected at of having confirmed to form between fat and particularly low-density lipoprotein (LDL) and the glucose fat-AGEs plays pathogenic effects in forming, and wherein the formation of foam cells shows accumulating of atherosclerotic plaque.The protein of low-density lipoprotein (LDL) and the oxidation of fat composition and saccharification cause the cell ldl receptor can't discern apo B composition, have prolonged the circulating half-life of this LDL by means of macrophage " scavenger " acceptor, AGE acceptor and other special cells mechanism simultaneously and have caused absorbing better the LDL (ox-LDL) of oxidation or the LDL that modifies in addition.The ox-LDL menses tube wall macrophage encytosis that increases is transformed into them and shows that the foam cells with fully loaded fat that early atherosclerosis damages is relevant.Above-mentioned research proves that also the AGE of LDLs modifies the potentiality that increased lipid oxidation.
AGEs " family " comprises can be separated and be characterised in that the metastable kind of chemical constitution, and other kind is unstable or reactive and their structure determination has become knotty problem thus.Can " catch " unstable or reactive AGEs by special chemical reagent, and for therapeutic purposes, this class reaction and capture-process are used to not only understand structure in depth but also be used to suppress saccharifying.AGE-fat can also be stable, unsettled or reactive.
Disturb the chemical process of (or inhibition) advanced glycation can have huge curative effect to the evaluation prompting of the pathogenic potentiality of AGEs.In this respect, having had been found that a series of reagent, is representative instance with aminoguanidine (also claiming Pimagedine), and they are useful saccharification inhibitor.Infer in theory this compound (with similar its other compound) can with the carbonyl moiety reaction of the early stage glycation product of target protein (or other biomolecule), described target protein with the original non-enzyme reaction of glucose or another kind of reducing sugar after form, and prevented the reaction of further formation advanced glycosylation end product thus.
Various other inhibitor of advanced glycation reaction also are known, think effective especially to the Maillard reaction stage of the inhibiting effect that is produced by aminoguanidine and analog thereof outside the most responsive stage.For example, has effective inhibitor that substituent some compound of active aldehydes (such as acetaldehyde) or its composition are the advanced glycation approach.Think that this activity is that the glycosyl-amino partial reaction of the saccharification product that forms in the starting stage by this class active aldehydes reagent and Maillard reaction produces, promptly these reagent and Amadori and Heyns rearrangement product (they are early stage saccharification products) react.Other reagent that can have similar capabilities is that those comprise conservative material in conjunction with primitive, the described hydrophilic peptide ring district of containing total 17-18 amino acid cysteine combination in conjunction with primitive of guarding, this is initial discovery and definite in antiseptic protein lysozyme and lactoferrin.More particularly, typical reagent comprises the molecule with hydrophilic loop district, and this hydrophilic loop district has the R of meeting

Carry out a series of experiment with the relation between the incidence of the AGEs rising of further research and proof tobacco and combustion by-products (tobacco smoke) and formation.Particularly and listed as this paper, these experiment confirm tobaccos and accessory substance thereof contain the soluble reaction saccharification intermediate product (this paper is called saccharification toxin (glycotoxins)) of significant quantity, this intermediate product can promote the formation of AGE and produce with aging and diabetes in AGE accumulate relevant whole secondary molecules and physiological complication, and they are mutagenesis, and subsequently they can participate in causing disease, such as cancer.This scheme and experiment subsequently are as follows.360mg/ml is pressed in the preparation of material and method tabacco water extract in PBS concentration by jolting tobacco sample was extracted 1 hour and (micropore, Bedford MA) carry out aseptic filtration by 0.45 μ m Millex-HA filter device.The preparation of smoke from cigarette condensation product
" water pipe " smoking device is used for and operation so that plume contact with aqueous solution.Aqueous solution (3mls) is put into glass Alan Mei Shi (erhlemeyer) flask that 25ml has the side neck, cigarette being contained in passed on the 500 μ l suction pipe tube heads in the hole in the flask plug.500 μ l suction pipe heads are extended to opening by flask side neck downwards, but do not enter aqueous solution.In case device installed then vacuum (about 20mmHg) fed the side neck of flask and lights cigarette.Change the tube head of suction pipe in some experiments: the commodity cigaratte filter of a slice 2 * 2mm is used to clog the suction pipe head, then with the 500mg aminoguanidine hydrochloride or sodium sulphate is placed between small pieces filter tip and the cigarette or do not let alone what material between them.In any experiment, from cigarette, remove the filter tip of the commercial preparation that connects in advance.With 5 cigarette lighters and smog is sucked among the PBS of 3ml equal portions.Before using the water condensate of smoke from cigarette is filtered by 0.45 μ m Millex-HA filter device (micropore).The detection that external AGE forms
To contain the microtitration flat board (joint study of fixing mouse tail tendon collagen, Cambridge, HA) cultivated 1 hour with TBS (PBS/0.05% Tween-20), the PBS hydroponics of the tobacco extract of usefulness serial dilution or smog contact under 37 ℃ is 18 hours then, with TBS washing 5 times, with the anti-AGE serum of rabbit polyclonal (the pAb RU 9.9.93 that in the TBS/0.1% lowlenthal serum, dilutes) cultivate 1 hour, with TBS washing 5 times and use and cultivate with the anti-rabbit igg of alkaline phosphatase (Sigma) conjugation and with TBS washing 5 times.Subsequently, by being to cultivate the AGEs colour developing that made combination in 45 minutes with 250mg/ml p-nitrophenyl phosphoric acid in 9.5 the diethanolamine and go up flat board to be carried out reading at 100mM, pH at the 405nm place at ELISA plate reader (Dynatech, MR 5000).Biolynx2.0 is used to generate typical curve and data extrapolation method.Saccharification toxin (glycotoxins) crosslinking active
The PBS solution that will contain 2mM EDTA as mentioned above contacts with tobacco smoke.To be dissolved in and contain 0,5 or the 40mg RNA enzyme A of the PBS/EDTA of 50mM aminoguanidine and identical 8 cigarettes contacts and in the time of 37 ℃, in the dark cultivated 0,5,8,24,48 and 72 hour.(Amicon, Beverly MA) remove unconjugated and low-molecular-weight material to use Centricon 10 concentrators.In order to estimate the formation of RNA enzyme dipolymer, use the separation gel [" nature " 227:680-685,1970] of 5% spacer gel and 12%, under reducing condition, sample carried out discontinuous SDS-PAGE and they are transferred on the nitrocellulose paper.Under 20 ℃, with lock solution (the not fatty milk of PBS/5%/1%BSA/0.2% Tween-20) with trace sealing 1 hour, use the anti-ribonuclease A antibody of the rabbit (BiodesignInternational with the horseradish peroxidase conjugation of in lock solution, diluting, Kennebunkport, ME) cultivate 45 minutes, wash up hill and dale and it launched with the PBS/0.2% Tween-20 according to the producer's instructions.Use AdobePhotoshop and the fluorograph of gained is processed processing with the light densitometry of the image of NIH image program determination (level and smooth, sharp-pointed and contrast enhancing).Fluoroscopic examination
In order to estimate the AGE specificity fluorescent, in the RNA enzyme sample of contact smoke from cigarette condensation product (preparation as mentioned above), measure when exciting at the 370nm place emission situation at the 440nm place with LS 50B fluorescence spectrometer (Perkin-Elmer).Determination of protein concentration fluorescent value with 0.5mg/ml.Mutagenicity research
As described in [] such as Ames, carry out the mutagenicity detection test.Briefly, in Oxoid nutrient broth (Difco) under 37 ℃ with Salmonella bacterial strain TA98, TA100, TA1535 and TA1537 (present that provides by doctor B.N.Ames) overnight incubation, with they in 0.1M sodium phosphate buffer (pH7.4) with the smoke from cigarette condensation product of serial dilution cultivate 1 hour, parallelly do three parts, the concentration fixed of then they being pressed the 0.1ml/ flat board is on minimum glucose flat board.Down should the flat board overnight incubation and the revertant number on each flat board counted at 37 ℃.The mensuration of serum AGE-apoB
Use aforesaid monoclonal anti AGE capture antibodies and anti-apoB-HRP conjugate (JBC, 267:5133-5138,1992), pass through sandwich ELISA measures the apoB (AGE-apoB) of AGE modification in human serum amount.Give value of sample and be that unit represents from typical curve with apoB-AGE U/ml serum.The apoB-AGE of a unit is defined as the activity of 1 μ g apoB (LDL).The mensuration of AGE
Use as (PNAS USA 90:6434-6438 and above) described in the generation glucose AGE epi-position of deriving AGE monoclonal antibody specific (IgG1 subclass), measure AGEs in the human serum by competitive ELISA.Become to belong to the hole that the sample of the range of linearity is tested in this detection for serial dilution, measure the AGE immunoreactivity in the parallel mode of doing three parts.With synthetic AGE-BSA reference material is that benchmark calculates AGE unit.The susceptibility of this test is in 5 U AGE/ml and the test and the coefficient of variation of test bay is respectively 5% and 8%.The result contains the tobacco of the saccharification toxin (glycotoxins) that promotes that AGE forms in the body and the water extract of smoke from cigarette
Beginning is extracted water-soluble reaction saccharification toxin (glycotoxins) by the mode that immerses PBS from the cigarette tobacco sample.Whether can induce AGE to form in order to detect saccharification toxin (glycotoxins) in the tobacco, this water extract be added in the flat board of glue primordial covering, continue 18 hours.Use the anti-AGE polyclonal antibody of specificity to detect the existence of the AGEs of up-to-date formation on the tropocollagen molecule.Accompanying drawing 5A represents the comparable situation that formed by the AGE that U.S.'s cigarette of 8 kinds of trades mark is induced.Impelled AGE formation partly from all extracts of accepting the detection trade mark.It should be noted that trade mark E (the brand of cigarette D of " soft " amount) has the activity that this higher class forms AGE than trade mark D.This discovery (when with other " common " and " soft " trade mark carry out paired comparisons the time continue to reappear) reflect the difference in the tobacco processing course probably and show that the content of tar and other assay method of cigarette " intensity " do not rely on saccharification toxin (glycotoxins) content.
For saccharification toxin (glycotoxins) volatilization that determines whether tobacco to be derived, we form in the test at AGE and have detected the smoke from cigarette condensation product.In order to collect any volatility saccharification toxin (glycotoxins), we have installed a kind of smoking device, and wherein the smog suction of the cigarette of spontaneous combustion in the future is equipped with in the flask of PBS solution.In a kind of trial of closer simulating the mode that lung tissue is contacted smoke from cigarette, the smog of experiment is contacted with PBS at drag, but do not pass through solution foaming.Immediately the PBS (smoke from cigarette condensation product) of smog contact is added to after the preparation with in the microtiter well of glue primordial covering and their are reacted spend the night.As leaf tobacco extract, the smoke from cigarette condensation product can rapid induction forming by the AGEs of the anti-AGE polyclonal antiserum identification of rabbit.The AGEs that is produced by smoke from cigarette depends on concentration (accompanying drawing 5B) and time (unlisted data), and by solubility AGE inhibitor (aminoguanidine) directly being added to (unlisted data) in the hole or can in the dose dependent mode, suppressing AGEs by the smoke from cigarette generation by means of making smog pass through aminoguanidine crystallization post (accompanying drawing 5C).The saccharification toxin (glycotoxins) that the tobacco that smog by sodium sulphate contrast post contains smog derives forms AGEs on the target thing ability does not influence (accompanying drawing 5C).The smoke from cigarette condensation product is low 10 times at the specific activity tabacco water extract that impels AGE to form, and this prompting can make some saccharification toxin (glycotoxins) be damaged by combustion process or the system that is used to catch volatility saccharification toxin (glycotoxins) and AGEs is invalid.It is unsettled that the AGE that finds in leaf tobacco extract and smoke from cigarette condensation product forms activity: if in the time of-20 ℃ freezing this solution and before detection, melt or be retained in and keep on ice or at room temperature more than 5 hours, then AGE forms activity and can't detect.
Also can estimate the ability that smoke from cigarette saccharification toxin (glycotoxins) induces AGE to form by on the RNA enzyme A of contact smoke from cigarette condensation product, measuring AGEs characteristic fluorescence pattern.Shown in accompanying drawing 6A, for the time that increases, the RNA enzyme A of contact smoke from cigarette condensation product shows AGE type fluorescence and depends on the time increase, (promptly exciting the back) in the emission of 410nm place at the 370nm place, this inhibition that is increased in the aminoguanidine that reaches capacity after 24 hours and in incubation, existed.Saccharification toxin (glycotoxins) can cross-linked proteins
One of feature of reaction reducing sugar is that they can impel between the susceptibility functional group in the molecule and the formation of intermolecular cross-linking.In order to prove that the reactive saccharification toxin (glycotoxins) in tobacco and the smog also has this characteristic, we have detected saccharification toxin (glycotoxins) and the crosslinked ability of RNA enzyme.With the sample culturing different time of smoke from cigarette condensation product with RNA enzyme A, by the molecular weight on the SDS-PAGE gel they are separated, make their colour developings with anti-RNA enzyme A antiserum then.Use this technology, the applicant can determine that the formation of RNA enzyme A-RNA enzyme A dipolymer depends on the time and reached capacity in 24 hours.In a kind of dose dependent mode, the formation of dipolymer can be subjected to the inhibition of aminoguanidine, and this shows that cross-linking process depends on the saccharification toxin (glycotoxins) (accompanying drawing 6B) that contains carbonyl.Saccharification toxin (glycotoxins) is mutagenesis
Above-mentioned research has proved that reducing sugar can react and induced mutation in bacterium and mammalian cell with DNA external.The reducing sugar of high intracellular concentration (Robison ester) causes mutation rate to increase in the Escherichia coli.Equally, the mouse tire of the hyperglycaemia that causes because of the parent diabetes of contact shows the mutation rate that doubles.
In this experiment, a large amount of bacillus typhi murium bacterial strains (TA98, TA100 and TA1537) are contacted with the smoke from cigarette condensation product in typical A mes mutagenesis testing mode.In bacterial strain TA98, noticed active sudden change activity, but in other bacterial strain, do not found.As observable in the accompanying drawing 7, TA98 contacts the sudden change that causes dose dependent to be increased with the smoke from cigarette condensation product of the recruitment of up-to-date preparation.When TA98 contacted with the mutagen that can cause frameshift mutation also original sudden change to be replied in histidine operon, its can be grown on the nutrient culture media that lacks histidine.With the quantity that has reduced revertant before PBS contacts by the smog (saccharification toxin (glycotoxins) molecule of significantly removing or having neutralized and contained carbonyl) of the dry post of aminoguanidine.In the reaction of DNA and above-mentioned reducing sugar, observed similar mutagenic activity.This is that the applicant recognizes that the mutagenic activity in the smoke from cigarette does not need to carry out the report first that metabolic activates by the P450 system.May also not observe this activity in the past, for example Yi Qian worker mainly in organic solvent, prepared smog extract and at noticeable time bar post analysis mutagenic activity.The instability of saccharification toxin (glycotoxins) requires the express-analysis mutagenic activity in the water extract.The water smoke from cigarette condensation product that requires at room temperature or on ice to cultivate more than 5 hours no longer is a mutagenicity.Saccharification toxin (glycotoxins) impels AGEs to form on serum proteins in vivo
Research will react the possibility that saccharification toxin (glycotoxins) or AGEs absorb in vivo behind the smoke from cigarette in contact below, and this process is undertaken by the amount of the AGEs that check forms on the serum proteins as the total surrogate markers thing of body burden.Blood sample from other healthy smoking person and non-smoker
In this research, detect AGE serum proteins level and albumen apoB-AGE.AGE-apoB level among the smoker (324+/-140U/ml, n=9) be significantly higher than (p<0.01, non-matching StudentShi t-check) non-smoker (177+/-33, n=10) and the serum AGE level among the smoker (202+/-76 AGE U/ml n=23) is significantly higher than the serum AGE level (146+/-31 AGE U/ml) among (p<0.02) non-smoker.In the smoking group all are inhaled the above cigarette of 1 bag individual every day, but do not limit their smoking history.Similarly research relate to be present in blood in the amount and the relation that contacts the smoke from cigarette degree of AGE of apoB or other haemocyanin combination.The sum of this contact will can be used for directly and the analysis of indirect contact smog situation.In fact, this test is similar to the hemoglobin A of the blood-glucose total amount that the preceding 30 day time limit of contact obtain
ICTest.Level that it should be noted that AGE haemocyanin and AGE-apoB among the smoker almost with identical [the AGE haemocyanin 200-400U/ml of observed situation in the patient who suffers from diabetes; AGE-apoB 300U/ml].
For determine whether can measure the reactive raising of AGE para-immunity behind the clear and definite contact tobacco smoke, from the experimenter of custom smoking, get blood sample, at first get blood sample after 18 hours, get blood sample after the experimenter continuously inhales 5 cigarettes again when finishing at interval in 18 hours then in the interval cigarette smoking.Use standardization sandwich type ELISA program in from the LDL fraction of these blood samples, to compare the AGE degree of modification of apoB so that detect AGE-apoB.In carrying out this standardization detection test, anti-AGE antibody is fixed on the surface of detecting the hole catching the AGE ornamental equivalent of sample, and will commercially available anti-apoB monoclonal antibody/horseradish peroxidase (HRP) conjugate that gets be used to detect by the mutually combine apoB of any AGE modification of fixing of the specificity with the anti-AGE antibody of being fixed.
Briefly, the serum fraction for preparing low-density lipoprotein (LDL) enrichment by following steps: the polyglycol (molecular weight is 8000) with 900 μ l 6.66% is handled 100 μ l blood serum samples 15 minutes, centrifugal (14,000rpm, 10 minutes) and in μ l 0.5%SDS, gained is precipitated solubilising and spend the night.In order to make up test panel, to resist AGE antibody (being monoclonal antibody 4G9 in this case) to be fixed on the surface of microtitration flat board by under the dilutability of institute's titration, cultivating, after this block non-specific binding by BSA solution replacement capture antibodies solution with 1%.Be that 0.05% SDS cultivated 1 hour with three parts of parallel cultivations of the serum fraction of LDL enrichment (or suitably LDL reference material dilution of titration) and with their in test panel with the ultimate density in the damping fluid then, the conjugate (be in this case available from and anti-apoB/ horseradish peroxidase (HRP) conjugate of the BiodesignInternational that uses by dilution in 1: 500) that this moment flat board is washed and adds the commercially available anti-apoB monoclonal antibody/enzyme that gets is to detect the apoB of any combination.Washing is dull and stereotyped and add suitable colour developing HRP substrate (such as o-phenylenediamine (o-phenyline diamine) (OPD)) after 1 hour cultivation, and behind suitable culture period with the reference wavelength of 570nm for to read OD to impinging upon the 450nm place.Generally according to principle well-known in the art, the optium concentration of all ingredients (for example coated antibody and detect antibody) and best pH, detergent concentration, damping fluid composition, culture period and other special characteristic contrasted each other changing so that the sandwich type immunity tolerance determination method of modifying at the AGE of this apoB of being used for makes the sample signal maximization and the non-specific background " noise " that will disturb drops to bottom line.In this experiment, the AGE-apoB value before the smoking be 218 ± 1 and smoking after value be 241 ± 3 apoB-AGE units/mg apoB (wherein being the activity of the commercially available LDL reference material that gets of 1 μ g/ml (for example available from Cappel)) with the apoB-AGE unit definition.The applicant has studied this evidence, has been the AGE modification that smoking can increase special blood constituent (apoB of LDL) tempestuously.The mensuration of AGE level can provide relevant experimenter the information of recent smoking history on this prompting sample composition.In addition, because that the AGE of LDL modifies is relevant with the pathological mechanisms of deleterious effect health, so this further points out applicant smoker can have benefited from limiting measure as the AGE of the excessive contact of tobacco consumption result generation.

Tobacco and tobacco product, comprise (for example) tobacco smoke AGEs also as antigen or haptens, so that guiding antibody is oriented to the AGE structure relevant with tobacco especially.This antibody-like (identical with the present invention) is used to successively discern and suppresses and relevant with tobacco successively AGE structure.For example, by making up the immunoassay of using the relevant AGE antibody of the anti-tobacco of the present invention, can measure degree by the AGEs modifying protein relevant with tobacco.Discuss as above-mentioned, and depend on the half life period of the protein of modification like this, the immunochemistry of AGE epi-position on protein example (such as haemocyanin) measured the index that recent tobacco consumption (for example by smoking) is provided.Equally, the immunochemistry of AGE epi-position on circulation and/or histone can be detected the therapeutic process that is used to monitor with reagent of the present invention, by with tobacco or tobacco smoke in AGEs reaction, these reagent relate to inhibition and accumulate by the excessive of AGEs that uses tobacco to produce.
By from tobacco or from smog, separate the AGEs relevant with tobacco, for example by preparing the water extract that contains AGE (as mentioned above) of tobacco or tobacco smoke condensation product, can prepare the immunogene of the various haptens, antigen and the conjugation that meet the present invention AGEs relevant easily with tobacco.Can be with this extract as a kind of various immunogenes that increase the antibody of identification specificity epi-position or its characterization of molecules, this immunogene can be in a preferred embodiment, regard the AGEs of extract as haptens, according to the widely used scheme in this area, use a large amount of well-known divalence coupling reagents arbitrarily, all as if the such carbodiimide of EDC, with these haptens correspondingly with arbitrarily several preferred carrier protein couplings, described preferred carrier protein comprises, keyhole hemocyanin (KLH) for example, thyroglobulin, and bovine serum albumin(BSA) most preferably.No matter the source how, can be with the AGEs relevant with tobacco, no matter be independent or with the carrier protein coupling and no matter be pure or partial-purified form is used to confirm good immunization protocol, thereby be created in the extensive application is useful antibody and relevant immunoreagent, and this is owing to the specificity that is used for the antibody of the characterization of molecules of tobacco associated products.
Be a preferred scheme below, any several animal species carried out immunity inoculation be oriented to the polyclonal antiserum of the protein conjugate of the AGE relevant that described animal comprises, for example mouse, rat, hamster, goat, rabbit, and chicken with tobacco with generation.First three kind of above-mentioned animal species is the selection that needs especially, because of they can be used for producing subsequently the hybridoma that can secrete the hapten specificity monoclonal antibody.Can finish generation easily by any several schemes of this area general implementation, and described scheme has been described and has been suitable for by merging the condition of the immortalization of the immunity inoculation splenocyte that produces with suitable clone (for example myeloma cell line) from the described hybridoma of immunity inoculation animal splenocyte.The described scheme that is used to produce hybridoma also provides certain methods, and these methods can be used for selecting and clone immune spleen cell/myeloma cell's hybridoma and are used to discern the hybridoma clone that secretion stably is oriented to the antibody of required epi-position.To be used to generate polyclonal antiserum more at large such as rabbit and the such animal species of goat, but no matter finally whether need polyclonal antiserum or monoclonal antibody, generally begin carrier protein and a kind of adjuvant of hapten transformation, together carry out administration such as complete Freund ' s adjuvant (Complete Freund ' s Adjuvant).Can give immunity inoculation by any approach, generally by in the peritonaeum, intramuscular or intradermal approach; Come preferred some approach according to the kind and the final type that produces antibody of institute's immunity inoculation in the art.Subsequently, general with a kind of adjuvant, give booster immunization such as alum or incomplete Freund ' s adjuvant (Incomplete Freund ' s Adjuvant).After original immunity inoculation, give booster immunization at set intervals; General 1 month is suitable interval, and the 1-2 behind each booster immunization gets blood sample between week.On the other hand, sometimes various so-called hyperimmune schemes (generally with the nearer booster immunization in space be feature) timely are used to produce a kind of trial that is better than the antihapten antibody in the anti-carrier protein antibody.
For in any several easy modes, comprise (for example) Ouchterlony diffusion gel and the direct hapten specificity immunity titre in the ELISA scheme, can compare the antibody titer after raising in the blood sample.In a kind of typical directly ELISA, a kind of definite antigen is fixed on the surface of detecting the hole (generally in 96 holes or microtitration flat board), detect the hole by flushing subsequently and separate a series of cultures to remove unconjugated binding partner.As non-restrictive example, detect dull and stereotyped hole and can hold a kind of dilution of haptens/carrier conjugate, the aqueous solution of buffering, preferred situation is that wherein carrier protein is different from the used albumen that is used for the generation antibody animal that immunity inoculation detects; For example can detect serum to the detection hole of modifying with the AGE/BSA conjugate relevant of immunity inoculation with tobacco from the AGE/KLH conjugate immunity inoculation animal of being correlated with tobacco.On the other hand, detect the surface by cultivating to modify with haptens separately.In general, the surface of detecting the hole is contacted with the solution of a kind of irrelevant protein (such as casein) with unappropriated position on the sealing frosting.After neutral buffered solution flushing, one of a series of antiserums of hole and the serial dilution that is prepared by significant blood sample are contacted (elementary antiserum) with salt that generally contains a kind of degree that non-specific interaction is minimized and detergent.Once more after the flushing, be fixed on the quantity that detects the detection antibody on the hole by cultivating with the commercially available enzyme that gets-antibody conjugates can estimate by interacting with required haptens or haptens/carrier conjugate, the antibody moiety of wherein this hyperconjugation thing directly is oriented to and is used to produce elementary sero-fast kind; For example, if elementary antiserum increases in the rabbit body, can will in the goat body, increase and use as secondary antibody so with the commodity preparation of the anti-rabbit antibody of several enzymes (such as horseradish peroxidase) conjugation.After producer's regulated procedure, in colorimetric detection method, can estimate the amount of this secondary antibody quantitatively by the activity of correlation conjugate enzyme.Can change many relevant ELISA or radio-immunity tolerance scheme (such as competitive ELISA s or sandwich ELISAs) arbitrarily, all these all are well-known in the art, thereby determine the antiserum of required high titre; Be that special antiserum provides correct positive findings (for example greater than 1/1000 and more preferably greater than 1/10,000) when high dilution.
Similar immune tolerance scheme can be used to estimate the culture supernatants of the hybridoma that comes free immunity inoculation animal splenocyte preparation.In the antiserum or hybridoma supernatant of so characterization, require to use the various control cultures (for example with different carrier protein together) of relevant and haptens that structure is different or antigen, and omit all ingredients in the immune metrics process and minimize and discern from false positive result and false negative result's the antibody specificity and the reliable measurement result of titre so that will detect non-specific signal in testing.The kind of the control cultures of Shi Yonging is well-known in this respect.In addition, identical common immune tolerance scheme is used subsequently together (being that the antibody of being found is the specificity structure determinative that has high titre and relate to the AGEs relevant with tobacco) with the antiserum of being discerned by said process.The relevant AGE antibody (no matter being polyclonal or monoclonal) of the required anti-tobacco that this class latter can be used and instructions are also packed in handled easily person's the kit formulation with other useful reagent (including, but not limited to the molecular criteria thing of one group of AGES relevant with tobacco) and thinning agent arbitrarily.
As mentioned above the relevant AGE antibody of the anti-tobacco of Sheng Chenging (and particularly this class monoclonal antibody) also can be used for discerning, separation, AGE epi-position that enrichment is relevant with tobacco with purifying.This process can be finished by technology well known in the art, for example passes through following steps: the known preparation that contains meaningful epi-position is contacted, rinses out the material of unconjugated material, wash-out specificity combination then and analyzes its chemical constitution so that measure the specific molecular form of the AGEs relevant with tobacco with the sessile antibody that is used in particular for described epi-position.

Can eliminate saccharification toxin (glycotoxins) with aminoguanidine spraying tobacco
In the present embodiment, tobacco leaf is handled with aminoguanidine (a kind of AGE forms inhibitor), and observed the formation that saccharification toxin (glycotoxins) can not impel AGE molecule in the body.The loose tobacco leaf that equates with the amount of 5 cigarettes with the 5mls solution spray that contains following concentration aminoguanidine: 10mg/ml, 1mg/ml after the 0.1mg/ml spraying, ties up tobacco leaf and cultivated 7 days down at 37 ℃ with aluminium foil.Then tobacco leaf is rolled into cigarette and in the pipe device of embodiment 3 and 4, lights (mentioned above).Use external AGE mentioned above to form determination method and measure saccharification toxin (glycotoxins) content.As shown in accompanying drawing 9, the dose dependent of having observed saccharification toxin (glycotoxins) content reduces.
Discuss
Above-mentioned disclosure and embodiment have proved the biological and chemical relation and the effect of the protein glycation of before having illustrated, and are based on the pharmacokinetics that organ sensory characteristic and tobacco are handled and consume.Therefore, owing to also observed the many vascular complications relevant with smoking in the diabetic with high circulation and tissue bond AGE level, this paper has studied the possibility that smoking impels AGE to form.More particularly, the listed data of this paper comprise up-to-date content, and this content proof has also exemplified existence and the activity that this paper is defined as a group reagent of saccharification toxin (glycotoxins).The water extract of tobacco and smoke from cigarette contains saccharification toxin (glycotoxins), remarkable reactive reducing sugar or saccharification intermediate product, and they in vitro and in vivo can rapid induction AGE form on protein and at external generation dna mutation.Can from sample, remove these activity by making smog through the dry post of aminoguanidine (the effective and specific inhibitor that a kind of AGEs forms).
Have the characteristic of many uniquenesses from the saccharification toxin (glycotoxins) of smoke from cigarette, these characteristics can distinguish reducing sugar, glucose and the Robison ester of saccharification toxin (glycotoxins) with above-mentioned research.Most importantly their extreme reactivity: take glucose with reporting of being write down or Robison ester is opposite to induce the AGE that can measure to form a couple of days to several weeks, the saccharification toxin (glycotoxins) that tobacco derives can induce AGE to form in a few hours.When most reducing sugars (such as glucose) need transhipment to enter tenuigenin, can think saccharification toxin (glycotoxins) cell membrane by bacterial cell easily.In addition, in healthy people, can be absorbed and react with haemocyanin successively by lung from the saccharification toxin (glycotoxins) of smoke from cigarette.Although we do not measure the chemical constitution of saccharification toxin (glycotoxins), we can infer that they have carbonyl and may have dicarbapentaborane, and this is because can remove them or make their quenchings with aminoguanidine.Saccharification toxin (glycotoxins) may be a kind of product that the product that forms in the Maillard reaction that causes in the tobacco processing procedure is reset.The instability of saccharification toxin (glycotoxins) means when handling tobacco and when it is aging, can forming and consume they and other Mei Lade product (may be the reason that causes smog fragrance) consistently in the detachment process.
The AGEs that is formed by tobacco saccharification toxin (glycotoxins) in the body can partly cause the atherosis incidence of disease of smoker's medium sized artery to increase.Have a large amount of evidences to show that AGEs plays a role in the external and body on atherosclerotic pathology: (1) has proved AGEs and the linked groups's collagen cross-linking that is used to increase linked groups's rigidity.(2) AGEs of collagen cross-linking as catch the circulation haemocyanin with covalent, such as the reaction " focus " of lipoprotein.(3) the combination meeting of endothelial cell AGE acceptor increases permeability, synthesizing of the anti-set accelerator thrombomodulin of minimizing and the synthesizing of increase procoagulant tissue factor of blood vessel.(4) AGEs of tissue bond can make cell-derived nitrogen oxide quenching with chemical mode, suppresses the vasodilation of nitrogen oxide dependence thus.(5) the verified AGE that contains the phosphatide of amine modifies the oxidation that can cause fat.The cell ldl receptor can not discerned the LDL of oxidation, and macrophage scavenger receptor can be removed the LDL of oxidation.The vascular wall macrophage that fat carries is the characteristic foam cells of finding in fat line and the infringement of other class early atherosclerosis usually.(6) vascular tissue that significantly raises is relevant with the acceleration angiosis of diabetes kidney failure disease latter end with round-robin AGEs.(7) albumin that the external source AGE of normal immature rat of injection and rabbit modifies in the intravascular can produce and be similar to observed blood vessel change in the animal body of suffering from the vascular diseases relevant with diabetes with aging.With the animal of external source AGE albumin injection show that the vascular wall permeability increases, monocyte migratory activity and attacking the blood pressure response increase that detects the back with acetylcholine and nitroglycerine in interior subcutaneous and artery is all (periarteriolar) space.[PNAS 89: 12043-12047 such as Vlassara, 1992].It is desirable to expectation and have the activity identical with the AGEs that serum and histone reaction form with above-mentioned AGEs by saccharification toxin (glycotoxins).
Saccharification toxin (glycotoxins) can also make the incidence of disease of cancer among the smoker increase.Except that with protein and fat on amino reaction, reducing sugar can also with the amino reaction of nucleic acid.External use reducing sugar cultivation DNA or mononucleotide can produce to be similar to the AGE compound that combines with protein and fat viewed absorbance log and fluorescence are changed.Show noticeable mutation rate increase with the bacteria plasmid DNA of glucose or Robison ester cultivation or the cultivation of mammal shuttle vector DNA.(Bucala etc., 1984, PNAS, 81: 105-109; Bucala 1985, PNAS82: 8439-8442; Lee AT and Cerami, A.1987, PNAS84: 8311-8314).Because the reducing sugar of above-mentioned research can pass through bacterial cell membrane, so although they can be added in the bacterial growth media, they can not produce the sudden change in the bacterium.Yet, having proved that Robison ester can induce the sudden change in Escherichia coli (DF40 and DF2000) the glycolysis mutant, described mutant can be accumulated glucose-6 phosphoric acid in its tenuigenin.Universals in all these results of study are that the major part sudden change that is produced by reducing sugar is to insert body or deletant.
((1994) FASEB magazine 8: 545-550), promptly parent hyperglycaemia environment is to the influence of embryo growth in the mouse body in the work that the most compellent evidence of reducing sugar mutagenicity comes free Lee etc. to be done in the mammal.As eye's lens and red blood cell, embryonic cell does not need insulin that glucose is shifted by its film.To contain bacterial gene (lacI, a kind of evident characteristic mutagenesis label) integrates the trangenic mice embryo of duplicate and implants in the diabetes and contrast alternative precursor that chain urine rhzomorph induces.In the DNA from the embryo who implants the diabetes parent, the lacI mutation rate is significantly higher than from the situation of implanting control mice.
Although the mammal that suffers from diabetes has the serum level of glucose of rising, there is not verifiable evidence to prove that any class cancer increases in their bodies.Glucose can freely not enter mammalian cell; It needs insulin to exist to stimulate its migration.Therefore in ripe mammal body, concentration of glucose depends on serum level of glucose in the born of the same parents.Yet, to notice that importantly saccharification toxin (glycotoxins) is more effective more than glucose.As glucose and Robison ester, they can produce in a kind of aminoguanidine dependence mode inserts and/or deletion mutant, but does not resemble these other reducing sugar, and saccharification toxin (glycotoxins) can pass through cell membrane easily.
In a word, our discovery shows that saccharification toxin (glycotoxins) (finding) can partly cause the increment rate of observed atheroma vascular diseases and cancer among the smoker in smoke from cigarette.In smoking process, saccharification toxin (glycotoxins) the suction alveolar with high concentration in alveolar, can suck them blood flow and suck the pulmonary parenchyma cell.In case be in the blood flow, then saccharification toxin (glycotoxins) can be induced and be formed the part of AGE and quicken development of atherosclerosis thus on serum and vascular wall albumen.Saccharification toxin (glycotoxins) can also with the nucleic acid reaction in the pulmonary parenchyma nucleus, thereby induced mutation and possible cancer.
The present invention can be summarised in other form or otherwise carry out and can not break away from its essence or essential characteristic.Therefore regard the disclosure of the specification as illustrative and nonrestrictive in all respects, scope of the present invention represented by appended claim, and the institute in identical purpose and scope changes and includes therein.
