MY-673 is a colchicine binding site inhibitor (CBSI), that inhibits tubulin polymerization. MY-673 inhibits the ERK signaling pathway, which in turn affects SMAD4 protein expression levels in the TGF-β/SMAD pathway. MY-673 inhibited cell proliferation, migration and induced apoptosis in vivo and in vitro.
