title: Design and semisynthesis of novel fredericamycin A derivatives with an improved antitumor profile.
abstract: We report the design, semisynthesis, and biological activity of a series of fredericamycin (1) derivatives. Within this series compound 1e combines low nanomolar cytotoxic potency in vitro, increased tumor cell line selectivity, and in vivo activity in a human xenograft model.
