It was discovered that most of target compounds showed promising anticancer activities, particularly for 8n, which had a significant HDACs inhibitory and antiproliferative activities comparable to or slightly stronger than SAHA against human carcinoma cells. Furthermore, compound 8n exhibited much better selectivity for HDAC1 over HDAC6 and HDAC8 than SAHA. In addition, compound 8n also could dose-dependently induce cancer cell cycling arrest at G0/G1 phase and promote the expression of the acetylation for histone H3 and tubulin in vitro. Therefore, our novel findings may provide a new framework for the design of new selective HDAC inhibitor for the treatment of cancer.展开更多
