Monomethyl auristatin D Hcl (MMAD Hcl), a potent tubulin inhibitor, is a toxin payload in antibody drug conjugate.
IC50 value:
Target: Tubulin; ADCs toxin
For comparison purposes, the ADC A1 -mc-MMAD and/or A1 -vc-MMAD were used. The linker payload, mc-MMAD (6-maleimidocaproyl-monomethylauristatin-D) was conjugated to the A1 anti-5T4 monoclonal antibody through a cysteine residue at a ratio of approximately 4 drug moieties per antibody molecule. The linker payload mc- Val-Cit-PABA-MMAD or vc-MMAD (maleimidocapronic -valine-citruline-p- aminobenzyloxycarbonyl- monomethylauristatin-D) was conjugated to the A1 anti-5T4 monoclonal antibody through a cysteine residue at a ratio of approximately 4 drug moieties per antibody molecule (Antibody-drug conjugates Patent: WO 2013068874 A1).
