Maitansine (INN), or maytansine (USAN), is a cytotoxic agent. It inhibits the assembly of microtubules by binding to tubulin at the rhizoxin binding site.[1]

It is a macrolide of the ansamycin type and can be isolated from plants of the genus Maytenus.[1]

Maytansinoids[edit]

Derivatives of maitansine are known as maytansinoids.[2][3] Some are being investigated as the cytotoxic component of antibody-drug conjugates for cancer treatment,[4] and the antibody-drug conjugate trastuzumab emtansine is an approved drug for the treatment of certain kinds of breast cancer in the EU and in the US.[5][6]

Examples of maytansinoids are:
