生物活性
MC-GGFG-DX8951 is a drug-linker conjugate for ADC with antitumor activity by using DX8951 (a DNA topoisomerase I inhibitor), linked via the protease cleavable MC-GGFG linker. MC-GGFG-DX8951 is a DX8951 derivative with MC-GGFG linker, in which DX8951 was covalently connected via a peptidyl spacer (Gly-Gly-Phe-Gly), which is assumed to be stable in circulation, and were cleaved by lysosomal enzymes following ADC internalization into tumor tissue. MC-GGFG-DX8951 is very useful to prepare DX8951 antibody conjugate (ADC).

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
