Imidazopyridine-fused [1,3]-diazepinones part 2: Structure-activity relationships and antiproliferative activity against melanoma cells
Résumé
We recently described a pyrido-imidazodiazepinone derivative which could be a promising hit compound for the development of new drugs acting against melanoma cells. In this study, a series of 28 novel pyrido-imidazodiazepinones were synthesized and screened for their in vitro cytotoxic activities against the melanoma MDA-MB-435 cell line. Among the derivatives, seven of them showed 50% growth inhibitory activity at 1 μM concentration, and high selectivity against the melanoma cell line MDA-MB-435.
