MedKoo CAT#: 319501

CAS#: 856925-71-8

Description: Blebbistatin is a myosin II inhibitor. Blebbistatin stabilizes the super-relaxed state in skeletal muscle. Blebbistatin exert antitumorigenic properties in human hepatocellular carcinoma cells by interfering with intracellular HuR trafficking. Blebbistatin is phototoxic to human cancer cells under exposure to blue light. Blebbistatin suppresses Ca(2+)-induced and "sensitized"-contraction of skinned tracheal muscles from guinea pig. Blebbistatin, a myosin II inhibitor, suppresses contraction and disrupts contractile filaments organization of skinned taenia cecum from guinea pig.
