Description
Technical field
The present invention relates to pharmaceutical chemistry field, cystatin field specifically, is specifically related to formula I compound and preparation method thereof and purposes in pharmacy.
Background technology
Different according to catalyst mechanism, proteolytic enzyme mainly can be divided into serine protease, L-Cysteine HCL Anhydrous, aspartate protease, serine/threonine protein enzyme and metalloprotease 5 classes.L-Cysteine HCL Anhydrous mainly comprises ubiquitination enzyme (DUBs), caspase, calpain and kethepsin etc.
Tumour be to take cell self to exchange the wrong responses of the signals such as ganglion cell's growth, differentiation, function and apoptosis be feature.From in essence, these cell processes by transcribing, the regulation and control such as protein translation, synthetic and degraded, any one link is made mistakes and is all likely promoted tumour to occur, and protein degradation is often left in the basket in this importance wherein.Eukaryotic protein degradation has lysosomal pathway and proteasome pathway, the outer and transmembrane protein of the former degradation of cell, albumen in latter degradation of cell.
Proteasome pathway needs Ubiquitin-proteasome system (UPS) to participate in.This system is comprised of multiple different protein, comprises ubiquitin, ubiquitin activating enzyme E1, ubiquitin binding enzyme E2, ubiquitin ligase E3, DUB and proteasome.The protein that need to be degraded is transported to proteasome after ubiquitin label and explains on mark, and DUBs can reverse this process, and ubiquitin is cut down from substrate protein.
Increasing research shows, the de-control of UPS and the many diseases of the mankind exist substantial connection as tumour.The successful listing of proteasome inhibitor Velcade (Velcade) is also from having verified clinically the validity of this system as anticancer target spot.Yet along with the generation of miss the target side effect and resistance, the application of Velcade is still restricted.People start to pay close attention to and are positioned at inhibitor proteasome upstream, other member of this system in recent years, expectation can find specificity more by force, cancer therapy drug, especially DUBs inhibitor that toxicity is less.
DUBs is typical L-Cysteine HCL Anhydrous, has been found that it is as relevant in tumour, inflammatory disease, nerve degenerative diseases, virus infection etc. with some disease.Ubiquitin-specific protease (USP) is a class maximum in DUBs family, is also to study at present a more deep class.USP7 in this class members has been found that in the cells such as colorectal carcinoma, bladder cancer and prostate cancer and has overexpression, and can make kinds of tumors supressor inactivation, as (Biochem Soc Trans2010,38:137-143) such as p53, PTEN, FOXO4.
At present, the USP7 inhibitor of bibliographical information is mainly divided into 4 classes chemical structure: pyrrolidone compound (EP 2206725 A1), 9-chlorine tetrahydro acridine amide derivatives is as HBX19 818 (US2011/0177105, Chemistry & Biology2012, 19:467-477), itrile group Indolepiperidine analog derivative is as HBX41 108 (Mol Cancer Ther 2009, 8:2286-2295, ChemMedChem 2010, 5:552-558) and nitrothiophene analog derivative as P5091 (WO 2010/114881 A1, Cancer Cell 2012, 22:345-358).The article that Chauhan D equals to deliver on Cancer Cell for 2012 has reported that thereby P5091 is by suppressing the activity induction multiple myeloma cells apoptosis of USP7, and can overcome Velcade resistance (Cancer Cell 2012,22:345-358.).All there is the problems such as the strong not or specificity of activity is high not in these compounds of having reported, therefore, not yet has so far a molecule to enter the clinical study stage.
