(-)-Blebbistatin is a selective cell-permeable inhibitor of non-muscle myosin II ATPases and the active enantiomer of (+)-blebbistatin. It rapidly and reversibly inhibits Mg-ATPase activity and in vitro motility of non-muscle myosin IIA and IIB for several species (IC50 = 0.5-5 µM), while poorly inhibiting smooth muscle myosin (IC50 = 80 µM​).
