(-)-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.
