Bis-sulfone-(PEG24)-Glu-Val-Cit-PAB-MMAE is a drug-linker conjugate for ADC. Bis-sulfone-(PEG24)-Glu-Val-Cit-PAB-MMAE contains a linker and bioactive small molecule toxins MMAE. Bis-sulfone-(PEG24)-Glu-Val-Cit-PAB-MMAE can conjugate with NN2101 (anti c-Kit ) for synthesizing NN3201. NN3201 rapidly internalizes and inhibits SCF-driven signaling, thereby delivering its payload to induce cell cycle arrest and apoptosis. NN3201 exhibits significant c-Kit-dependent anti-tumor efficacies in various tumor models, such as small cell lung cancer (SCLC) and gastrointestinal stromal tumor (GIST) [1].
