title: Inhibition of Src kinase activity by 7-ethynyl-4-phenylamino-3-quinolinecarbonitriles: identification of SKS-927.
abstract: Of a series of 7-ethynyl-3-quinolinecarbonitriles, the most potent Src inhibitory activity was observed with 4-[(2,4-dichloro-5-methoxyphenyl)amino]-6-methoxy-7-[4-(4-methylpiperazin-1-yl)but-1-ynyl]-3-quinolinecarbonitrile (SKS-927). Variation of the solubilizing amine tail or removal of the methoxy group from either C-6 of the quinoline core or C-5 of the aniline headpiece led to reduced activity.
