Synthesis and antitumor activity of novel C-7 paclitaxel ethers: discovery of BMS-184476

J Med Chem. 2001 Dec 20;44(26):4577-83. doi: 10.1021/jm0102607.

Abstract

The preparation of C-7 paclitaxel ethers is described. Various substituted ethers were prepared via activation of the corresponding methylthiomethyl ether followed by alcohol addition. Variation of the C-7 ether group as well the 3' side chain position led to the discovery of a novel taxane, BMS-184476 (4), with preclinical antitumor activity superior to paclitaxel.
