PNU-159682是奈莫柔比星(Nemorubicin)的肝脏代谢物,可抑制DNA拓扑异构酶II,其效力比奈莫柔比星高三个数量级,IC50为20–100 pM,同时PNU-159682也不是外排转运蛋白的底物[5d]。
Tumor cell stratification based on MMAE responses IC50 (pM)
Strikingly, we found that the strong responders to the ADC in vivo also had high MMAE sensitivity in in vitro cell viability assays (IC 50 <1 nM) ( Table 2). In contrast, the moderate in vivo...
Monomethyl auristatin E (MMAE), a payload for multiple
It is known that MMAE is released from the ADC following binding, internalisation and proteolytic degradation in target tissues. A striking discrepancy in systemic MMAE levels has been observed across species with 50-fold higher MMAE levels in human than that in rodents when normalised by ADC dose with unknown mechanism.
