Design, synthesis and biological evaluation of novel arylpiperazine derivatives on human prostate cancer cell lines

摘要

A series of novel arylpiperazine derivatives was synthesized. The in vitro cytotoxic activities of all synthesized compounds against three human prostate cancer cell lines(PC-3, LNCa P, and DU145) were evaluated by a CCK-8 assay. Compounds 8, 10, 13, 17 and 20 exhibited strong cytotoxic activities against the tested cancer cell lines(IC_(50)<3 μmol/L). In addition, these compounds exhibited weak cytotoxic effects on human epithelial prostate normal cells WPMY-1. The structure–activity relationship(SAR) of these arylpiperazine derivatives was also discussed based on the obtained experimental data.
