Synthesis and biological evaluation of diarylamines with antitumor activity / 药学学报

ABSTRACT

By structural modifications of our previous leads 1-3, 18 diarylamines were designed, synthesized and evaluated with a human tumor cell line panel, including A549, DU145, KB, and KB-vin cell lines, resulting in the discovery of new antitumor agents A6 and B2 with low micromolar G50 values ranging from 1.55-2.10 micromol x L(-1) for above cell lines, and A9 with GI50 values ranging from 1.55-2.10 micromol x L(-1) specially for DU145, KB, and KB-vin cells. Current structure-activity relationships are helpful for further lead optimization.
