(-)-Blebbistatin ((S)-(-)-Blebbistatin) is an S enantiomer of blebbistatin. It is a potent and selective myosin II inhibitor with IC50 ranging from 0.5 to 5 μM.

JB061 is a nonmuscle myosin inhibitor, demonstrating selective inhibitory activity with IC50 values of 4.4 μM (Cardiac muscle myosin), 9.1 μM (Skeletal muscle myosin), and >100 μM (Smooth muscle myosin II). It exhibits limited efficacy in reducing ATPase activity, with an IC50 exceeding 200 μM. Furthermore, JB061 displays cytotoxic effects on COS-7 cells, evidenced by an IC50 value of 39 μM.

Phenamacril (JS39919) is acyanoacrylate fungicide, has powerful inhibition against Fusarium species, especially to Fusarium graminearum. Phenamacril is a specific Fusarium myosin I inhibitor.

JB062 is a chemical compound acting as a nonmuscle myosin inhibitor, exhibiting IC50 values of 1.6, 5.4, and >100 μM against skeletal muscle myosin, cardiac muscle myosin, and smooth muscle myosin II, respectively. It selectively exhibits cytotoxicity towards human cancer cells without affecting normal cells. The compound is applicable in research fields concerning muscle spasticity, chronic musculoskeletal pain, and hypertrophic cardiomyopathy.

JB002, a myosin II inhibitor, exhibits potent activity with an IC50 of ≤10 μM. It holds potential for research applications in muscle spasticity, chronic musculoskeletal pain, and hypertrophic cardiomyopathy.

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.

Danicamtiv (MYK-491) is an inotropic agent and it also is a selective allosteric activator of cardiac myosin. Danicamtiv increases cardiac systolic function and preserves mechanical efficiency.

HA-100 is an inhibitor of protein kinase
