ML-7 HCl

ML-7 is an inhibitor of smooth muscle myosin light chain kinase (MLCK) with a Ki value of 0.3 µM and displays reversible, ATP-competitive inhibition of Ca2+-calmodulin-dependent and -independent smooth muscle MLCKs. ML-7 also inhibits PKA and PKC with Ki of 21 μM and 42 μM, respectively.

Biological Activity

Description ML-7 is an inhibitor of smooth muscle myosin light chain kinase (MLCK) with a Ki value of 0.3 µM and displays reversible, ATP-competitive inhibition of Ca2+-calmodulin-dependent and -independent smooth muscle MLCKs. ML-7 also inhibits PKA and PKC with Ki of 21 μM and 42 μM, respectively.

0.3 μM(Ki) 21 μM 42 μM
In vitro
In vitro Inhibition of MLCK by ML-7 induces activation of caspase-3 in adherent MCF-10A and MCF-10A Ras-transformed cells[2]. Its treatment results in a dose-dependent decrease in MLC20 phosphorylation and a corresponding increase in cell death of SMC(smooth muscle cells). The inhibitory effect of ML-7 on MLCK is highly selective. The Ki of ML-7 for MLCK is 0.3 μM, while its Ki for protein kinase A is 21 μM and for protein kinase C is 42 μM. Overexpressing Bcl-2 can protect cells against apoptosis induced by ML-7[4].
Cell Research Cell lines MCF-10A cells, MDCK cells
Concentrations 40 μM
Incubation Time 16 h
Method Cells are treated with vehicle alone, Blebbistatin, ML-7, ML-9, latrunculin A or Y-27632 in media without serum at varying concentrations and time points before being fixed or prepared for FACS analysis. Untreated cells are also serum starved for the duration of the inhibitor treatment. Stock solutions of each agent are made in DMSO (50 μM Blebbistatin, 5 mM LA), 50% ethanol (10 mM ML-7), 70% ethanol (20 mM ML-9) or water (20 mM Y-27632) and are maintained at -20°C.
In Vivo
In vivo ML7 is able to improve Vascular endothelial dysfunction(VED) and atherosclerosis(AS) by regulating the expression of the tight junction (TJ) proteins zona occludens (ZO)-1 and occludin via mechanisms involving MLCK and MLC phosphorylation in high-fat diet-fed rabbits. ML7 decreases the expression of MLCK and MLC phosphorylation in the arterial wall of rabbits fed a high-fat diet and reduces lipid deposition lesions in AS rabbits[1].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
