Description
Technical field
The present invention relates to phthalimide analog derivatives and its preparation method and application, belong to chemical medicine.
Background technique
Tumour is the mutation and function that body cell leads to its gene level in the case where inside and outside tumorigenesis factor acts synergistically for a long time
Regulation is abnormal, to promote cell hypelproliferative and cause to occur to convert and the neoformation of formation.China is new every year at present
Raw about 212.7 ten thousand people of tumor patient sum or so, wherein have 1,000,000 or so malignant tumour new life patient every year；Meanwhile entirely
There are about the existing patients of 268.5 ten thousand or so tumour for state, wherein the existing patient of malignant tumour about 148.5 ten thousand or so, benign tumour is existing
There is patient about 1,200,000 or so.There are about 1,540,000 people or so every year for national tumor mortality number, that is to say, that tumor patient crowd is just
It is expanded with the speed of about 600,000 people every year.Main means currently used for oncotherapy have operation, radiotherapy, chemotherapy and biology to control
It treats, other effective means further include endocrine therapy, traditional Chinese medical herbal treatment, thermotherapy and radiofrequency ablation therapy etc..Due to existing each
Kind treatment means respectively have its optimal adaptation disease, also respectively there is its deficiency, so, in order to improve cure rate, it is safe and effective to still need to exploitation
Targeted therapies.
Poly adenosine diphosphate-ribose polymerase-1 (poly (ADP-ribose) polymerases, PARPs) is to be present in eukaryon
A kind of ribozyme in cell is a novel targets of current treatment of cancer, can be catalyzed ADP- ribose unit from nicotinoyl amine gland
Purine dinucleotides (nicotinamide adenine dinucleotide, NAD+) it is transferred to various receptor proteins.PARP ginseng
With DNA reparation and transcriptional control, not only there is key effect in adjusting cell survival and death process, while being also tumour hair
Central transcription factor in exhibition and inflammation generating process.PARP is in the DNA single stranded gaps (SSBs) of base excision repair are repaired
With key effect, inhibit its activity that can enhance the effect of radiotherapy and DNA damage based chemotherapy drug.
PARP-1 inhibitor has prospect in two field performances very much.First is to treat as sensitizer to improve anticancer drug
Effect, since most of antineoplastic is all to inhibit cancer cell to increase to cause the mechanism of DNA damage, and PARP-1 can be repaired
The DNA of damage makes repressed cell generate certain drug resistance, to influence antitumous effect.Pass through PARP-1 inhibitor and its
The mode of the use in conjunction of his radiotherapy or chemotherapy class drug can have the function that reduce dosage and heighten the effect of a treatment.Certainly,
There is antitumous effect of the preclinical study observation PARP-1 inhibitor as single formulation in BRCA-1/2 (-/-) cell strain.
Second is the treatment to cell ischemia injury.In ischemia injury, PARP-1 consumes a large amount of ATP by excessive activation,
Cell is set to occur the reaction such as to crack and cause inflammation.Two protection processes can be induced in the presence of PARP-1 inhibitor, on the one hand
Store a certain amount of NAD+And ATP, so that periphery cell can reparation of the spontaneous completion to DNA in the case where there is damage situations；Another party
Face plays certain anti-inflammatory effect again, avoids accelerating the damage to cell because of immune response.
Therefore, the drug inhibited to PARP is developed, is had for the treatment of tumour and cell ischemia injury
Significance.

NAD+, in free NAD+It is detected after wash-off.Experimental method is summarized as follows: in freshly prepd reaction buffer (50mM Tris-
HCl(pH 8.0),50mM NaCl,10mM MgCl2, 1mM DTT, 1%DMSO, and 20g/ml activated dna) in preparation instruction
Substrate；PARP is put into substrate solution, is gently mixed；With instrument Acoustic Technology (Echo 550, LabCyte
Inc.Sunnyvale, CA) untested compound for being dissolved in DMSO is put into reaction mixture；Incubation at room temperature 20 minutes；It will32P-
NAD+It is put into reaction solution, starting reaction；It is incubated at room temperature 2 hours；Reaction solution is put on filter membrane and clear with phosphate buffer
It is detected after washing；Data are analyzed with Excel and GraphPad Prism and inhibiting rate or IC50 value is calculated.
2, cell culture
It is removed from liquid nitrogen the tumour cell for freezing conservation, 37 DEG C of water bath with thermostatic control rewarmings is immediately placed in and melts, in sterile item
It is washed 1 time under part with culture medium.Then with complete culture medium inoculated in culture bottle, at 37 DEG C, 5%CO2It is cultivated in incubator,
Second day displacement fresh cell medium.The passage of suspension growth cell: after cell culture 2~3 days, training is taken out from incubator
Bottle is supported, collects cell suspension in centrifuge tube, 1500rpm/min is centrifuged 3min, goes supernatant, cell precipitation training completely
It supports base weight to hang and blow and beat uniformly, then divides to 3~5 bottles and cultivate.It passes on 1 time within general 3~4 days；The passage of adherent growth cell: thin
Born of the same parents are adherent to cover with to 80% or so of bottom of bottle, and culture bottle is taken out from incubator, sucks culture medium, washs 1 with 0.25% pancreatin
It is secondary, 0.25% pancreatin digestive juice digestion is then added, after observation cellular contraction is rounded, complete medium is added and terminates digestion,
And blowing and beating makes cell dispersion fall off, and collects cell suspension, 1500rpm/min is centrifuged 3min, removes supernatant, and cell precipitation is used
Complete medium is resuspended and blows and beats uniformly, then divides to 3~5 bottles of bottle cultures.It passes on 1 time within general 3~4 days.
3, cell growth inhibition assay (mtt assay)
The cell of logarithmic growth phase is collected, with every hole 2.5 × 103~1 × 104A quantity is inoculated in 96 orifice plates, 37
DEG C, 5%CO2Cell incubator in overnight incubation 24 hours, drug to be measured is diluted using DMEM culture medium and is added to 96 holes
In plate, 8 gradients of every kind of drug, each gradient contains 3 multiple holes.In dosing group, by gradient (final concentration is respectively 30,10,
0.33,0.11,0.036,0.012 μM) culture medium solutions of 100 μ L compounds is added in every hole, and each concentration sets 3 multiple holes；Yin
Property the every hole of control group in the 100 μ L of blank cultures for containing 1 ‰ DMSO, totally 6 multiple holes are added；It is only added in the every hole of blank control group
100 μ L culture mediums.Plate is placed in 37 DEG C, 5%CO2Culture 72 hours in cell culture incubator.Drug-treated group, stealthy control group
20 μ LMTT solution (5mg/mL) are added with the every hole of blank group, continue culture 2-4 hours, after first a ceremonial jade-ladle, used in libation is formed, terminates culture, inclines
It goes to every hole after supernatant to add 150 μ L DMSO (being then directly added into 50 μ L 20%SDS solution for suspension cell), is shaken on shaking table
15~20 minutes.Every hole cell absorbance (OD 570) is detected under 570nm wavelength with microplate reader, takes its average value record knot
Fruit.Cell proliferation inhibition rate=(control group OD570Experimental group OD570)/(control group OD 570- blank OD570) × 100%.Most
Afterwards, half-inhibitory concentration is fitted using GraphpadPrism software.
