Synthesis and anticancer activities of thieno[3,2-d]pyrimidines as novel HDAC inhibitors

Add time:07/29/2019    Source:sciencedirect.com

A series of thieno[3,2-d]pyrimidines bearing a hydroxamic acid moiety as novel HDAC inhibitors were designed and synthesized. The structures of the new synthesized compounds were confirmed using IR, 1H, 13C NMR spectrum. Compounds 11–13 showed potent inhibitory activities against HDACs with IC50 values at 0.38, 0.49 and 0.61 μM. Most of target compounds displayed strong anti-proliferative activity by a MTT assay on three human cancer cell lines including HCT-116, MCF-7 and HeLa. Compound 11, having potent inhibitory activities against HDACs, induced apoptosis and G2/M cell cycle arrest in HCT-116 cell line.
