(-)-Blebbistatin Chemische Eigenschaften,Einsatz,Produktion Methoden

Chemische Eigenschaften
Bright Yellow Solid
Verwenden
(?)-Blebbistatin has been used to investigate the effect on cardiac contractility and effect of thrombin on actomyosin contractility
Verwenden
Blebbistatin blocked myosin II-dependent cell processes. It blocks cell blebbing rapidly and reversibly. Also rapidly disrupted directed cell migration and cytokinesis in vertebrate cell. It blocks both blebbing and cytokinesis at 50-100μM. [a]D= -103
Definition
ChEBI: (S)-blebbistatin is the (S)-enantiomer of blebbistatin. It is a blebbistatin and a tertiary alpha-hydroxy ketone.
Allgemeine Beschreibung
(?)-Blebbistatin, a myosin II ATPase inhibitor, does not affect other members of myosin superfamily like I, V and X. Blebbistatin is highly light sensitive, and photobleaching can reverse its effect completely. Blebbistatin is a commonly used as excitation-contraction uncoupling agent in cardiovascular physiology. Blebbistatin controls the inhibitory effect of thrombin on intercellular Ca₂⁺ wave propagation. Blebbistatin reduces cardiac contractility by stabilizing the OFF state of the thick filament.
Biologische Aktivität
Selective inhibitor of myosin II ATPase activity (IC 50 ~0.5-5 μ M); active enantiomer of (±)-blebbistatin ((?-1,2,3,3a-Tetrahydro-3a-hydroxy-6-methyl-1-phenyl-4H-pyrrolo[2,3-b]quinolin-4-one ). Inhibits contraction of the cleavage furrow without disrupting mitosis or contractile ring assembly. Rapidly and reversibly blocks cell blebbing, and disrupts directed cell migration and cytokinesis in vertebrate cells.
Biochem/physiol Actions
(-)-Blebbistatin is a cell cycle inhibitor; selective inhibitor of non-muscle myosin II.
