Background 
Monomethyl auristatin E (MMAE, vedotin) is a very potent antimitotic agent that inhibits cell division by blocking 
the polymerisation of tubulin. The family of auristatins are synthetic analogues of the antineoplastic natural 
product Dolastatin 10, ultrapotent cytotoxic microtubule inhibitors that are clinically used as payloads in 
antibody-drug conjugates. Antibody-drug conjugates enhance the antitumor effects of antibodies and reduce 
adverse systemic effects of highly potent cytotoxic agents. MMAE is actually desmethyl-auristatin E; that is, the 
N-terminal amino group has only one methyl substituent instead of two as in auristatin E itself.
