英文摘要The protein tyrosine phosphatases (PTPs) constitute a family of closely related key regulatory enzymes that dephosphorylate phosphotyrosine residues in their protein substrates. Malfunctions in PTP activity are linked to various diseases, ranging from cancer to neurological disorders and diabetes. As part of a project aimed at identifying small molecular inhibitors based on PTPs family, focusing on diabetes mellitus, tumorigenesis, and infection, we performed the high-throughput screening (HTS) of a library of 48000 synthetic compounds for six representative PTPs, including PTP1B, SHP-1, SHP-2, PRL-3, CDC25B and LAR, and 3a,4,5,9b-tetrahydro-3H-cyclopenta[c]quinoline analogues were identified as PTPs inhibitors. Keeping the core template complete, we began the modification of benzene ring, intending to find out the best modifying position in benzene ring and the proper amount of substitutions on it. Consequently, thirty-four compounds were designed and synthesized, and careful structure-activity relationship(SAR) study with respect to PTP1B, SHP-1, SHP-2, PRL-3, CDC25B and LAR was carried out. Finally, it was found that the compounds bearing a bulky substituent at 8-position of the cyclopentaquinoline acid turned out to be PTP1B inhibitors with good potency and selectivity against other assayed PTPs. The most potent PTP1B inhibitor in this series, compounds 31 and 35, show good activity(IC50 = 0.4 and 0.6 mu mol/L, respectively) and excellent selectivity for PTP1B over SHP-1, SHP-2, PRL-3 and LAR, and 30-fold selectivity over CDC25B. Due to time limit, the modification of core template is not sufficient enough, and it would be the direction of our further work to discover more potent core structures.
