Description: Mafodotin, also known as mc-MMAF and SGD-1269 or Maleimidocaproyl monomethylauristatin F, is a MMAF derivative having a Maleimidocaproyl linker (MC linker), which is ready to conjugate to antibody or other proteins or biopolymers. Mafodotin is a useful agent for make antibody drug conjugate (ADC) for targeted drug delivery. MMAF is a potent antimitotic and antitublin auristatin derivative with a charged C-terminal phenylalanine residue that attenuates its cytotoxic activity compared to its uncharged counterpart, MMAE.

Additional Information

Monomethyl auristatin F (MMAF) is a synthetic antineoplastic agent. It is part of some experimental anti-cancer antibody-drug conjugates such as vorsetuzumab mafodotin and SGN-CD19A. In International Nonproprietary Names for MMAF-antibody-conjugates, the name mafodotin refers to MMAF plus its attachment structure to the antibody. Monomethyl auristatin F is an antimitotic agent which inhibits cell division by blocking the polymerisation of tubulin. It is linked to an antibody with high affinity to structures on cancer cells, causing MMAF to accumulate in such cells. MMAF is actually desmethyl-auristatin F; that is, the N-terminal amino group has only one methyl substituent instead of two as in auristatin F itself. (
