Bis-8-hydroxyquinoline and bis-8-hydroxyquinaldine N-substituted amines: A single methyl group structural difference between the two heterocycles, which modulates the antiproliferative effects
uted N-benzyl or thiophenyl amines and their corresponding bis-8-hydroxyquinoline is reported. In vitro growth inhibitory effects of both series have been evaluated. It has been observed that analogs from the bis-8-hydroxyquinoline series exert nanomolar range activity, whereas the antiproliferative activity of the corresponding analogs from the bis-8-hydroxyquinaldine series was found to be drastically
