Synthesis, cytotoxicity and SAR of simple geiparvarin analogues

Abstract

Some simple geiparvarin analogues, in which the coumarin moiety has been replaced with an X-substituted benzene ring, are described. The compounds were tested on LoVo cells (human colon carcinoma cell line) and some of them show a cytotoxicity comparable with that of the prototype. A QSAR analysis was also attempted, but it did not provide satisfactory results, mainly because of the limited range of variation of the biological activity.
