Application

ML-9 has been used in the inhibition of myosin light chain kinase (MLCK) and non-muscle myosin IIA (NMIIA) in human corneal epithelial cells and HeLa cells.

Biochem/physiol Actions

ML-9 is myosin light chain kinase inhibitor. It inhibits insulin-induced translocation of glucose transporters GLUT4 and GLUT1 in a dose-dependent manner. ML-9 also inhibits agonist-induced Ca2+ entry into endothelial cells and catecholamine secretion in intact and permeabilized chromaffin cells. ML-9 promotes cell death in cancer cells by triggering accumulation of autophagic vacuoles. ML-9 impacts phosphorylation of myosin light chain kinase and alters trabecular meshwork shape and decreases intraocular pressure in rabbit eyes.

Endothelin-1 (ET-1), a potent vasoconstrictor, is believed to contribute to the pathogenesis of hypoxic pulmonary hypertension. Previously we demonstrated that contraction induced by ET-1 in intrapulmonary arteries (IPA) from chronically hypoxic (CH) rats occurred independently of changes in intracellular Ca2+
