Design,synthesis and antitumor activity of 6,7-disubstituted-4-(heteroarylamino)quinoline-3-carbonitrile derivatives

摘要

A series of new 6,7-disubstituted-4-(benzothiazol-6-ylamino)quinoline-3-carbonitrile derivatives(12a-l) were synthesized.The cytotoxicity of 12 new compounds was evaluated in AGS,HepG2 and HT-29 cell lines.The results showed that compounds 12g, 12h,12i,12k and 12l displayed more potent cytotoxic activities than Bosutinib,compound 12l exhibited the most potent antitumor activity among the tested compounds.
