MedKoo CAT#: 530537

CAS#: 110448-33-4

Description: ML-7 is a MLCK inhibitor. ML-7 inhibits smooth muscle myosin light chain kinase (MLCK) with a Ki value of 0.3 µM. ML-7 amplifies the quinocetone-induced cell death through akt and MAPK-mediated apoptosis on HepG2 cell line. ML-7 inhibits exocytosis of superoxide-producing intracellular compartments in human neutrophils stimulated with phorbol myristate acetate in a myosin light chain kinase-independent manner.
