Maytansinoids
Derivatives of maitansine are known as maytansinoids.[3][4] Some are being investigated as the cytotoxic component of antibody-drug conjugates for cancer treatment,[5] 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.[6][7]
Examples of maytansinoids are:
- Ansamitocin[3]
- Mertansine / emtansine (DM1)
- Ravtansine / soravtansine (DM4)
