MMAD 是一种有效的微管蛋白抑制剂,是抗体药物偶联物中的一种毒素有效载荷。
产品描述
MMAD is a potent tubulin inhibitor. MMAD is a toxin payload in antibody drug conjugates (ADCs).
体外活性
MMAD (Monomethyl Dolastatin 10) is coupled through a stable oxime-ligation process to yield several near-homogenous antibody-drug conjugates (ADCs) with a drug-to-antibody ratio of ~2.0. The resulting conjugates demonstrate good pharmacokinetic properties, potent in vitro cytotoxic activity against HER2+ cancer cells. The site-specific unnatural-amino-acid-based ADCs are shown to have increased in vitro cytotoxicity when compared with ADCs prepared by cysteine alkylation following native interchain disulfide reduction.
体内活性
The resulting antibody-drug conjugates (ADCs) exhibited complete tumor regression in rodents. They also have an improved toxicology profile in rats.
