Mc-MMAF是由高效微管抑制剂Monomethyl auristatin F (MMAF) 与保护基团maleimidocaproyl偶联而成。MMAF(一甲基澳瑞他汀F)为抗微管蛋白化合物,能通过阻断微管聚合抑制细胞分裂,较MMAE毒性低,可用于抗体偶联药物(ADC)。
Description | Mc-MMAF is a protective group-conjugated MMAF. MMAF is a more potent drug than Monomethyl auristatin E (MMAE), but is charged and relatively membrane-impermeable, is a potent tubulin inhibitor, is a toxin payload in antibody drug conjugate. Target: MMAF is a new auristatin derivative with a charged C-terminal phenylalanine that attenuates its cytotoxic activity compared to its uncharged counterpart, Monomethyl auristatin E (MMAE). Because of MMAF is highly toxic, it cannot be used as a drug itself. MMAF induces potent antitumor effects when conjugated via protease cleavable linkers to a monoclonal antibody targeting internalizing, tumor-specific cell surface antigens. The linker to the monoclonal antibody is stable in extracellular fluid, but is cleaved by cathepsin once the conjugate has entered a tumor cell, thus activating the anti-mitotic mechanism. | ||||||||||||||||
