DM1-SMe

Description: DM1-SMe (DM1-SSMe) is a potent inhibitor of maytansinoid microtubular. DM1-SMe is about 3 to 10-fold more potent than the parent drug Maytansine, with IC50s of 0.003 to 0.01 nM for DM1-SMe in a panel of human tumor cell lines. Target: ADC Cytotoxin, Microtubule Associated. Smiles: [H][C@@]12O[C@@]1(C)[C@H](CC(=O)N(C)c1cc(C\C(C)=C/C=C\[C@@H](OC)[C@@]3(O)C[C@]([H])(OC(=O)N3)[C@H]2C)cc(OC)c1Cl)OC(=O)[C@H](C)N(C)C(=O)CCSSC.
