Biological Activity
DM4, a structural analogue of maytansine, is a new thiol-containing and potent maytansinoid. DM4 is a cytotoxic maytansinoid drug. It is synthesized in order to link maytansinoids to antibodies via disulfide bonds. Maytansinoids inhibit tubulin polymerization and microtubule assembly and enhance microtubule destabilization, so there is potent suppression of microtubule dynamics resulting in a mitotic block and subsequent apoptotic cell death[1].

DM4 purchased from MedChemExpress. Usage Cited in: Curr Issues Mol Biol. 2023 Oct 5;45(10):8112-8125. [Abstract]
Cytotoxic activity of pegylated antibody fragment-drug conjugates in GD2-positive B78-D14 cell line. scFv-PEG4-DM4 (0-370 nM; 72 h) was more effective than scFv-PEG4-DM1 in inhibiting cell growth because the cytotoxicity was approximately twice as high for the FDC loaded with DM4 as opposed to that with DM1.
