(-)-Blebbistatin is a cell-permeable inhibitor for non muscle myosin II ATPase with IC50 of ~2 μM, does not inhibit myosin light chain kinase, inhibits contraction of the cleavage furrow without disrupting mitosis or contractile ring assembly.

Mavacamten（MYK-461）is a small molecule that reduces contractility by decreasing the ATPase activity of the cardiac myosin heavy chain.

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

Aficamten (CK-274) is a novel cardiac myosin inhibitor with an IC50 of 1.4 μM. Aficamten can be used for the research of hypertrophic cardiomyopathy (HCM).

MT-134 is a SkMII-specific inhibitor and has excellent exposure in muscles.

16-38-Thymosin β4 (cattle) is a Ca2+-independent MLCK activator with high affinity.

Sevasemten is an allosteric inhibitor of skeletal muscle myosin. Sevasemten exhibits selectively myosin inhibition with IC50s of ≤10 μM (skeletal), >100 μM (cardiac), respectively.

MPH-220 is a selective and orally active inhibitor of skeletal muscle myosin-2. MPH-220 enables muscle relaxation. MPH-220 is anti-spastic agent that can be used in the research of spasticity and muscle stiffness.

JB002 is a myosin II inhibitor, with an IC50 of ≤10 μM. JB002 can be used for the research of muscle spasticity, chronic musculoskeletal pain, and hypertrophic cardiomyopathy.

JB062 is a nonmuscle myosin inhibitor with IC50 values of 1.6, 5.4, and >100 μM for Skeletal muscle myosin, Cardiac muscle myosin, and Smooth muscle myosin II, respectively. JB062 has cytotoxic to human cancer cells but not normal cells. JB062 can be used in research of muscle spasticity, chronic musculoskeletal pain, and hypertrophic cardiomyopathy.

JB061 is a nonmuscle myosin inhibitor with IC50s of 4.4 μM (Cardiac muscle myosin), 9.1 μM (Skeletal muscle myosin), and >100 μM (Smooth muscle myosin II), respectively. JB061 poorly decreases ATPase activity (IC50>200 μM). JB061 shows cytotoxicity against COS-7 cells with an IC50 value of 39 μM.
