Synthesis and antiproliferative activity evaluation of new thiazole-benzimidazole derivatives using real-time cell analysis (RTCA DP)

Abstract

A series of new 2-[(5-substituted-1H-benzimidazol-2-yl)thio]-N-[4-[2-phenylthiazol-4-yl]phenyl]acetamide derivatives (4a-p) were synthesized according to the reported literature, and anticancer activity of the compounds was evaluated. Cytotoxic activity was confirmed by real-time cytotoxicity analysis system determining half maximal inhibitory concentrations (IC50) of the title compounds based on the dose-response curves derived by xCELLigence measurements against NIH/3T3, A549 and Caco2 cell lines for 24, 48 and 72 h exposure. Compound 4c was found to be as the most efficient molecule that exhibited selective antiproliferative activity against both of the cancer cells.
