Novel Tetrahydropyrido[1,2-a]isoindolone Derivatives (Valmerins): Potent Cyclin-Dependent Kinase/Glycogen Synthase Kinase 3 Inhibitors with Antiproliferative Activities and Antitumor Effects in Human Tumor Xenografts
摘要:
The development of CDK and GSK3 inhibitors has been regarded as a potential therapeutic approach, and a substantial number-of-diverse structures have been reported to inhibit CDKs and GSK-3 beta. in recent years. Only a few molecules have gone through or are currently undergoing clinical trials as CDK and GSK inhibitors. In this paper, we prepared valmerins, a new family containing the tetrahydropyrido[1,2-a]isoindone core. The fused heterocycle was prepared with a straightforward synthesis that was functionalized by a (het)arylurea. Twelve valmerins inhibited the CDK5 and GSK3 with an IC50 < 100 nM. A semiquantitative kinase scoring was realized, and a cellular screening was done. At the end of study, we investigated the in vivo potency of one valmerin. Mice exhibited good tolerance to our lead, which proved its efficacy and clearly blocked tumor growth. Valmerins appear also as good candidates: for further development as anticancer agents.
Herein we designed and synthesized three series of novel 8-morpholinoimidazo[1,2-a]pyrazine derivatives bearing phenylpyridine/phenylpyrimidine-carboxamides (compounds 12a-g, 13a-g and 14a-g). All the compounds were evaluated for their IC50 values against three cancer cell lines (A549, PC-3 and MCF-7). Most of the target compounds exhibited moderate cytotoxicity against the three cancer cell lines
Four series of phenylpicolinamide derivatives bearing 1H-pyrrolo[2,3-b]pyridine moiety (12a–e, 13a–f, 14a–f and 15a–i) were designed, synthesized and evaluated for the IC50 values against three cancer cell lines (A549, PC-3 and MCF-7) and c-Met kinase. Five selected compounds (13b, 15b, 15d, 15e and 15f) were further evaluated for the activity against HepG2 and Hela cell lines. Eighteen of the compounds
analogues N-(3-fluoro-4-(pyridin-4-yloxy)phenyl)-4- phenylpicolinamides(13a-k) and N-(3-fluoro-4-(pyridin-4-yloxy)phenyl)-5-phenylpicolinamides (14a-k) were designed and synthesized. METHODS Their structures were confirmed by various analytical methods, such as 1 H and 13 C NMR, m.p., MS, HRMS. All of them were evaluated for IC50 values against three cancer cell lines (A549, PC-3 and MCF-7). RESULTS Eleven

Design, synthesis and biological evaluation of phenylpicolinamide sorafenib derivatives as antitumor agents
Two series of phenylpicolinamide sorafenib derivatives (14a–k, 15a–k) were designed and synthesized. They were evaluated for IC50 values against three cancer cell lines (A549, Hela, and MCF-7) and VEGFR2/KDR, BRAF, and CRAF kinases. Fourteen target compounds showed moderate to excellent cytotoxicity activity against the different cancer cells with potency from the single-digit μM to nanomole range
