Synthesis and cytotoxic activity of new 9-substituted camptothecins.
Bioorg Med Chem Lett. 2008 May 01; 18(9):2781-7.BM

Abstract

A series of novel 9-substituted camptothecins derived from 9-formylcamptothecin were synthesized. The aldehyde was obtained from 10-hydroxycamptothecin or, better, by total synthesis. The compounds showed antiproliferative activity higher than that of the reference compound topotecan. Modelling suggested the possibility of a favourable interaction of small and polar 9-substituents with the topoisomerase I-DNA complex, which is consistent with the higher activity of these derivatives with respect to the corresponding 7-substituted camptothecins.
