Description
SC209 (3-Aminophenyl Hemiasterlin) is a 3-aminophenyl hemiasterlin derivative that serves as a cytotoxin for ADCs, targeting tubulin. SC209 has reduced potential for drug efflux via P-glycoprotein 1 drug pump compared with other tubulin-targeting payloads. SC209 exhibits antitumor activity and can be used in the synthesis of ADC molecules
