Abstract
The synthesis of five new tetracyclic benzopsoralen analogues, compounds 2-6, with 9H-xanthen-9-one or 9H-carbazole frameworks, is described. Their inhibitory effects on the growth of three human tumor cell lines (MCF-7, SF-268, and NCI-460) were evaluated, and discussed in terms of structure-activity relationship, taking into account both geometric and electronic features. Generally, the angular compounds showed significant biological activities, but the arrangement of functional groups also contributed to the overall activity.
