Estramustine depolymerizes microtubules by binding to tubulin.

Abstract excerpt

To investigate the mechanism of action of the antineoplastic drug estramustine, we compared its effects on human prostate cancer cells with those of vinblastine. At their respective concentrations that result in 50% inhibition of clonogenic growth, both drugs caused an accumulation of cells blocked at mitosis and similar dose- and time-dependent depolymerization of interphase microtubules. Also,...
