title: 3-Cyano-4,6-disubstituted-2(1H)-imino or oxopyridines: new antineoplastic agents with high selectivity towards leukemia cell lines.
abstract: Two series of 3-cyano-2(1H)-oxopyridine and 3-cyano-2(1H)-iminopyridine derivatives carrying various aryl substituents at position 4 and (4-((7-chloro or trifluoromethylquinol-4-yl)amino)phenyl) substituent at position 6 were synthesized and evaluated for their antitumor activity. Compounds 3f and 6d showed high selectivity towards leukemia cell lines with full panel median growth inhibition GI50 average sensitivity towards all cell lines (MG-MID) at 7.9 and 19.7 microM and leukemia subpanel GI50 average sensitivity towards leukemia cell lines (MG-MID) at 1.74 and 2.9 microM, respectively, also they exhibited full panel total growth inhibition TGI (MG-MID) at 34.8 and 59.0 microM and leukemia subpanel TGI (MG-MID) at 5.3 and 13.5 microM, respectively.
