Synthesis and biological evaluation of novel macrocyclic paclitaxel analogues

Org Lett. 2001 Aug 9;3(16):2461-4. doi: 10.1021/ol016124d.

Abstract

[reaction: see text] This work describes the synthesis of two novel macrocyclic taxoid constructs by ring-closing olefin metathesis (RCM) and their biological evaluation. Computational studies examine conformational profiles of 1 and 2 for their fit to the beta-tubulin binding site determined by electron crystallography. The results support the hypothesis that paclitaxel binds to microtubules in a "T" conformation.
