myosin light-chain kinase

Carbazochrome (Adchnon) is an antihemorrhagic, or hemostatic, agent that will cease blood flow by causing the aggregation and adhesion of platelets in the blood to form a platelet plug, ceasing blood flow from an open wound. It is hoped that this drug can be used in the future for preventing excessive blood flow during surgical operations and the treatment of hemorrhoids, but research on its effectiveness and the severity of possible side effects remains to be fairly inconclusive. Carbazochrome has been investigated for use in the treatment of hemorrhoids in a mixture with troxerutin.

W-7 hydrochloride (W-7 HCl), a calmodulin antagonist, inhibits Ca2+-calmodulin-dependent myosin light chain kinase and phosphodiesterase, W-7 hydrochloride induces apoptosis and has antitumor activity.

Midostaurin (PKC412) is a multi-targeted tyrosine kinase inhibitor with antitumor activity, exhibiting IC50 values ranging from 22 to 500 nM against PKCα/β/γ, Syk, Flk-1, Akt, PKA, c-Kit, c-Fgr, c-Src, FLT3, PDFRβ, and VEGFR1/2. Midostaurin is indicated for the treatment of acute myeloid leukemia (AML) and systemic mastocytosis (SM).

Myosin light chain kinase fragment 11-19 amide (MLCK(11-19) amide) acts as a substrate-specific peptide inhibitor of MLCK and inhibits hypotonicity-induced Ca2+ entry, with applications in human cervical cancer research [1] [2].

The smMLCK peptide is a specific inhibitor of smooth muscle myosin light chain kinase (smMLCK). It functions by mimicking the substrate and competitively inhibiting the binding of the natural substrate to the enzyme, thereby reducing kinase activity. This inhibition prevents the phosphorylation of the myosin light chain, which subsequently impedes muscle contraction.

MS-444 (BE-34776) is a smooth muscle myosin light chain kinase (MLCK) and HuR inhibitor with antitumor activity for triple-negative breast and colorectal cancer.

Ritodrine hydrochloride (NSC 291565) binds to and activates beta-2 adrenergic receptors of myometrial cells in the uterus, which decreases the intensity and frequency of uterine contractions. Ritodrine hydrochloride (NSC 291565) is a phenethylamine derivative with tocolytic activity. Specifically, Ritodrine hydrochloride (NSC 291565) probably activates adenyl cyclase, thereby increasing production of cyclic adenosine monophosphate (cAMP), which in turn enhances the efflux of calcium from vascular smooth muscle cells. A lack of intracellular calcium prevents uterine myometrial contractions. In addition, this agent may directly inactivate myosin light chain kinase, a critical enzyme necessary for the initiation of muscle contractions.

Rhodblock 6 is a Rho kinase (ROCK) inhibitor that specifically inhibits Rho kinase activity and the localization of phosphorylated MRLC (Myosin Regulatory Light Chain).

A-3 hydrochloride is a potent, cell-permeable, reversible, ATP-competitive non-selective antagonist of various kinases. It inhibits PKC and casein kinase I with Ki values of 47 μM and 80 μM, respectively[1], and also inhibits PKA (Ki=4.3 μM), casein kinase II (Ki=5.1 μM), and myosin light chain kinase (MLCK) (Ki=7.4 μM).

ML-9 (free base) suppresses MLCK, PKA, and PKC activity (Ki: 4, 32, and 54 μM, respectively). ML-9 (free base) is a selective and effective inhibitor of Akt kinase, inhibits myosin light-chain kinase (MLCK), and stromal interaction molecule 1 (STIM1) acti

ML-9 suppresses MLCK, PKA, and PKC activity with Ki values of 4, 32, and 54 μM, respectively. ML-9 is a selective and effective inhibitor of Akt kinase, inhibits myosin light-chain kinase (MLCK), and stromal interaction molecule 1 (STIM1) activity. ML-9 causes autophagy by stimulating autophagosome formation and inhibiting their degradation.

KT5926 is an effective and selective inhibitor of myosin light chain kinase. KT5926 is an analogue of K-252a, which blocks all responses to NGF. KT5926 selectively inhibits nerve growth factor-dependent neurite elongation.

ML-7 hydrochloride (ML-7 HCl) is a cell-permeable, reversible, effective, ATP-competitive, and specific inhibitor of myosin light chain kinase (Ki: 300 nM); also inhibits smooth-muscle myosin light chain kinase, PKA, and PKC.

ML 7 is an inhibitor of myosin light chain kinase that protects cardiac function from ischemia/reperfusion (I/R) injury.

MS 347a is a myosin light chain kinase (MLCK) inhibitor; an epoxide analog of sydowinin B (MS-347b).

SR-33805 is a calcium channel antagonist potentially for the treatment of atherosclerosis and heart failure. SR-33805 restored the MI-altered cell shortening without affecting the Ca(2+) transient amplitude, suggesting an increase of myofilament Ca(2+) sensitivity in MI myocytes. A SR33805-induced sensitization of myofilament activation was found to be associated with a slight increase in myosin light chain-2 phosphorylation and a more significant decrease on troponin I (TnI) phosphorylation. Decreased TnI phosphorylation was related to inhibition of protein kinase A activity by SR-33805.

Ritodrine hydrochloride (Standard) is the standard substance of Ritodrine hydrochloride, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Ritodrine hydrochloride (NSC 291565) binds to and activates beta-2 adrenergic receptors of myometrial cells in the uterus, which decreases the intensity and frequency of uterine contractions. Ritodrine hydrochloride (NSC 291565) is a phenethylamine derivative with tocolytic activity. Specifically, Ritodrine hydrochloride (NSC 291565) probably activates adenyl cyclase, thereby increasing production of cyclic adenosine monophosphate (cAMP), which in turn enhances the efflux of calcium from vascular smooth muscle cells. A lack of intracellular calcium prevents uterine myometrial contractions. In addition, this agent may directly inactivate myosin light chain kinase, a critical enzyme necessary for the initiation of muscle contractions.
