We recently described a pyrido-imidazodiazepinone deriv. which could be a promising hit compd. 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 derivs., seven of them showed 50% growth inhibitory activity at 1 μM concn., and high selectivity against the melanoma cell line MDA-MB-435.
