Elaboration of Simplified Vinca Alkaloids and Phomopsin Hybrids
摘要:
Nine simplified vinca alkaloids and phomospin A hybrids, in which vindoline moiety has been replaced by a simpler scaffold, have been elaborated to evaluate their activity on the inhibition of tubulin polymerization. This article deals with the synthesis of various simplified vinca alkaloids, using a stereoselective coupling of catharantine with reactive aromatic compounds and methanol as well as their subsequent condensation with a large peptide chain mimicking those of phomopsin A. Biological evaluation and molecular modeling studies are also reported.
Synthesis and antiproliferativeactivity of new vinca alkaloids containing an α,β-unsaturated aromatic side chain
摘要:
A new series of vinca-alkaloids derivatives containing various alpha,beta-unsaturated aromatic side chains was synthesized. Four new vinca-alkaloids derivatives showed selective cytotoxicities against KB tumor cell lines with IC50 value below 0.1 mu M, thus comparable with vinblastine. (C) 2015 Elsevier Ltd.
