Myosin

Blebbistatin, a myosin II inhibitor, is photoinactivated by blue light.

ML 7 hydrochloride is a selective inhibitor of myosin light chain kinase (MLCK).

Blebbistatin is a selective non-muscle myosin II (NMII) inhibitor, promotes directional migration of corneal endothelial cells (CECs) and accelerates wound healing, and better preserves cell junctional integrity and barrier function. Blebbistatin blocks cell migration.

A-3 Hydrochloride is an inhibitor of PKA (cAMP-dependent protein kinase, Ki=4.3μM) and cGMP-dependent protein kinase, Ki=3.8μM, PKC (protein kinase C, Ki=47μM), casein kinase I and II, and MLCK (myosin light chain kinase) ( Ki=7.4μM).

MS-444 inhibits the activity of purified smooth muscle myosin light chain kinase (MLCK) with an IC50 value of 10 μM.

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

2,3-Butanedione monoxime (BDM, Diacetyl monoxime, Diacetylmonoxime) is the well-characterized, low-affinity, non-competitive inhibitor of skeletal muscle myosin-II and inhibits skeletal and cardiac muscle contraction.

BTS is a potent inhibitor of Ca2+-stimulated myosin S1 ATPase (IC50 ~ 5 μM) and reversibly blocks the gliding motility.

OSU-T315 (ILK-IN-1) is a small Integrin-linked kinase (ILK) inhibitor with an IC50 of 0.6 μM, inhibiting PI3K/AKT signaling by dephosphorylation of AKT-Ser473 and other ILK targets (GSK-3β and myosin light chain).

ATM-3507 is a potent tropomyosin inhibitor with IC50s from 3.83-6.84 μM in human melanoma cell lines.

para-Nitroblebbistatin is a non-cytotoxic, photostable, fluorescent and specific Myosin II inhibitor, usd in the study of the specific role of myosin II in physiological, developmental, and cell biological studies.
