Description
Technical field
The present invention relates to field of medicaments, and in particular to 2 receptor antagonist Sarpogrelate of serotonin and serotonin synthesis
The compound medicament composition of inhibitor combination, compound medicine of the invention combination can be used for treatment dyslipidemia and prevention and treatment
Atherosclerosis.
Background technology
Major lipids form in blood includes triglycerides (Triglyceride, TG), high-density lipoprotein cholesterol
(High density lipoprotein cholesterol, HDL-C), low density lipoprotein cholesterol (Low density
Lipoprotein cholesterol, LDL-C) and C-VLDL (Very low density
lipoprotein cholesterol,VLDL-C).Dyslipidemia, is also hyperlipidemia, blood fat disorder, refers to that a variety of causes draws
The pathology that blood TG, LDL-C, VLDL-C concentration rise (based on TG, LDL-C rise performance) risen or HDL-C concentration decline
Performance, can also show as the rise of TG, LDL-C isoconcentration at the same time and HDL-C concentration declines.Wherein TG, LDL-C, VLDL-C are " no
Alright " lipid, and LDL-C is mainly converted by VLDL-C and formed, their haemoconcentration rise can directly result in Atherosclerosis
Change (Atherosclerosis, AS), and AS cardiovascular and cerebrovascular diseases thus occur；And HDL-C is a kind of " good " lipoprotein,
Its clinical value is can to drive reverse cholesterol transport -- AS spots cholesterol in the block is transferred to liver etc. and is excreted,
It haemoconcentration rise, at the same time " bad " lipid concentration reduce, show as T-CHOL (Total cholesterol,
TC=HDL-C+LDL-C+VLDL-C) ratio with HDL-C reduces, and can prevent and treat AS.
Lipidosis is the basis that AS is formed on arterial wall.Early stage is formed in AS, monocyte is by endothelial gap, inside
Macrophage is divided under film, it is macrophage-mediated to penetrate into intravascular subcutaneous LDL-C generations oxidative modification, form oxidized form
LDL-C (ox-LDL-C), further swallows a large amount of ox-LDL-C by A types scavenger receptor, causes lipid within endothelial cells to be accumulated, shape
Into foam cells.Foam cells is accumulated to form fatty streaks or even Lipid Plaque, that is, initially forms AS.The development of AS is in foam
On the basis of cell accumulation increase, patch increase, it is also possible to while there is calcium deposition, thrombosis etc..It is now recognized that body
Eliminating AS is completed by reverse cholesterol transport：AS spots cholesterol in the block can be replaced out by forming HDL-C, HDL-
C is conveyed into liver through blood, then is converted into bile acid in liver or is directly discharged by bile from enteron aisle, consolidates so as to complete courage
The counter transport process of alcohol and the elimination to AS patches.Therefore, the rise of blood LDL-C, VLDL-C concentration is to induce the main original of AS
Cause；And elevating blood HDL-C concentration can eliminate AS patches by promoting reverse cholesterol transport, so as to prevent and treat AS.
Many reasons can cause dyslipidemia.It is life style, such as high heat of long-term hyperphagia, food rich in fat, thermophilic
Poor eating habits such as wine and to lack physical exertion, stress, life irregular etc., it is considered to be it is important the reason for, and certain
A little secondary factors, cause blood fat as diabetes, nephrotic syndrome, and inherent cause are considered to interact with life style
It is abnormal.Clinical observation and zoopery have proven to：Blood " good " lipoprotein concentration reduces, the rise of " bad " lipoprotein concentration is
Cause the direct risk factors of AS, so that the cardiovascular and cerebrovascular diseases such as coronary heart disease, cerebral thrombus occur.Improve dyslipidemia, reduce blood
Liquid TG, LDL-C, VLDL-C are horizontal, improve HDL-C levels, are prevention and treatment AS, the important means of cardio-cerebrovascular diseases.
The key agents of clinical treatment dyslipidemia have Statins, fibrates, nicotinic acid class, cholic acid chelating agent, cholesterol absorption inhibitor
And n-3 polyunsaturated fatty acid classes etc., also the medicine of dyslipidemia is treated not over periphery serotonin system is acted on.
Serotonin (5-hydroxy tryptamine, 5-HT) be also thrombocytin, is that one kind is present in periphery and maincenter
Small-molecule substance, the physiological function of 5-HT is complicated, does not understand fully completely so far.
The synthesis of I .5-HT in two steps, the first step：Tryptophan is in tryptophan hydroxylase (tryptophan
Hydroxylase, TPH) catalysis under be changed into 5-hydroxyryptophan (TPH can be divided into two hypotypes：TPH1 and TPH2, TPH1 are deposited
It is periphery, TPH2 is present in maincenter)；Second step：5-hydroxyryptophan is in aromatic amino acid decarboxylase (aromatic
Aminoacid decarboxylase, AADC) catalysis under be changed into 5-HT.Therefore, can be respectively by suppressing TPH or AADC
Realize the suppression to 5-HT synthesis.
Fenclonine (parachlorophenylalanine or p-chlorophenylalanine, pCPA), not
Name:DL-4- chlorophenylalanines, DL- fenclonines etc., molecular formula：C9H10ClNO2, it is TPH inhibitor, no clinical practice
Report.
Carbidopa (Cabidoba, CDP), molecular formula：C10H14N2O4。
Benserazide (Benserazide, BSA), alias：Trihydroxy seryl hydrazine, Benseraside, Benseraside, benserazide,
Molecular formula：C10H15N3O5。
CDP and BSA is AADC inhibitor, is clinically used for the auxiliary treatment of Parkinson's disease, their collective effect is special
Point is periphery decarboxylase inhibitors, is not easily accessible maincenter, only suppresses periphery levodopa and is converted into dopamine, makes left-handed in circulation
The increase of DOPA content, also can inhibit 5-hydroxyryptophan and is converted into 5-HT, the cell of synthesis 5-HT is produced 5-HT and reduces.CDP and
BSA is also reported without the research for improving dyslipidemia.
II .5-HT acceptor 5-HT acceptors (5-HT receptor, 5-HTR) are present on cell membrane, belong to membrane receptor, 5-
HT receptor subtypes are complicated, it has now been found that with the presence of 7 big receptoroids, i.e. 5-HT1-7R, 5-HT1,4,5R is mainly distributed on maincenter, 5-
HT2,3,6,7R is mainly distributed on periphery.This 7 receptoroid is broken into further several hypotypes again.5-HT2R can be divided into 5-
HT2AR、5-HT2BR and 5-HT2CR.That periphery and maincenter are distributed is 5-HT2A,2BR, 5-HT2CR is primarily present in nervous centralis
5-HT is distributed with system, liver, skeletal muscle, visceral adipose tissue2A,2BR.With selective exclusion 5-HT2The medicine of R is few,
Know that Sarpogrelate belongs to selective 5-HT2R antagonists.
Sarpogrelate (Sarpogrelate, SAR) is a species specificity 5-HT2R blocking agents, molecular formula：C24H31NO6.Face
In bed application, SAR can inhibit by the platelet aggregation of 5-HT enhancings and suppression vasoconstrictor effects etc., be clinically used for improving chronic
The all symptoms of the ischemic such as ulcer, pain and creeping chill caused by arterial occlusive disease.Clinic has SAR to treat diabetic complication
The report of arterial obliterans of lower extremity.
The content of the invention
Combined the invention discloses a kind of 2 receptor antagonist Sarpogrelate of serotonin and serotonin synthetic inhibitor
Compound medicament composition form, said composition form have the function that collaboration improves dyslipidemia.It is different with blood fat available for treating
Normal relevant disease, particularly atherosclerosis.This composition is reducing the same of blood TG, LDL-C, VLDL-C level
When, HDL-C levels can be greatly improved, TC/HDL-C ratios are greatly reduced, therefore with the work of prevention and treatment atherosclerosis
With.

Normal curative effect is used individually significantly better than SAR or BSA, is produced obvious cooperative effect, is displayed that two compound treatment groups make serum
HDL-C levels are increased to the degree apparently higher than control group, TC/HDL-C ratios close to even less than control group；Compound SAR+
BSA-1, SAR+BSA-4 therapeutic effect are better than or are used individually equal to BSA, SAR.As a result prompt, the certain ratio of SAR and BSA compositions
The compound of example, has obvious synergistic effect, by weight ratio, SAR to dyslipidemia caused by treatment DEX:The proportion of BSA
For：6:1~1:7, with SAR in this experiment:BSA=1:1 compound (SAR+BSA-3) curative effect is best.
Table 6SAR+BSA compound medicines cause rat Dex the influence of dyslipidemia model
Note：Each administration group dosage is identical, is 30.0mg/kg. times, and twice a day, morning and afternoon is respectively once
TC (T-CHOL)=HDL-C+LDL-C+VLDL-C
