smcc dm1

SMCC-DM1 is a drug-coupler coupler consisting of a potent microtubule disrupter, DM1, and a coupler, SMCC, for the preparation of antibody-drug couplers.

Lys-SMCC-DM1 (Lys-Nε-MCC-DM1) is an antibody-drug conjugate (ADC) targeting human epidermal growth factor receptor 2 (HER2). It contains the microtubule polymerization inhibitor DM1 as the active metabolite, which inhibits microtubule polymerization. It is commonly used in breast cancer research.

(Rac)-Lys-SMCC-DM1 ((Rac)-Lys-Nε-MCC-DM1) is the racemic form of Lys-SMCC-DM1, which serves as a linker-payload component capable of inhibiting tubulin polymerization. It is also recognized as the active metabolite of T-DM1 [1].
