Synthesis and biological evaluation of cis-locked vinylogous combretastatin-A4 analogues: Derivatives with a cyclopropyl-vinyl or a cyclopropyl-amide bridge
摘要:
A series of novel combretastatin A4 analogues, in which the cis-olefinic bridge is replaced by a cyclopropyl-vinyl or a cyclopropyl-amide moiety, were synthesized and evaluated for inhibition of tubulin polymerization and antiproliferative activity. The derivative 9a with a (cis,E)-cyclopropyl-vinyl unit is the most promising compound. As expected, molecular docking of 9a has shown that only one of the cis-cyclopropyl enantiomers is a good ligand for tubulin. (C) 2009 Elsevier Ltd. All rights reserved.
