Abstract:

A series of novel N-methylpicolinamide-moiety containing diarylthiosemicarbazide derivatives was prepared and evaluated for their in vitro antiproliferative activity against three cancer cell lines(human alveolar epithelial cell A549, human lung cancer cell H460 and human colorectal cancer cell HT-29) by 3-(4,5-dimethyl)thiazolyl-diphenyltetrazoliumromide(MTT) assay. Six compounds(7b―7g) with halogen substituents exhibited preferable cytotoxicity against one or more cell lines in a low micromolar range. Especially, the most promising compound 7g exhibited remarkable antiproliferative activity with the IC50 values of 2.2, 1.8 and 5.2 μmol/L against A549, H460 and HT-29 cell lines respectively, which is comparable to sorafenib.
