Ansamitocin P3, a structural analogue of maytansine, was isolated from Nocardia. Structurally maytansine and ansamitocin P3 are polyketide macrolactams differing in the acyl groups at the C3 position. Ansamitocin P-3 inhibited the polymerization of tubulin and depolymerized the once polymerized tubulin. Ansamitocin P3 exerts antitumour properties.
