| | (+/-)-BLEBBISTATIN Usage And Synthesis |
| Description | (±)-Blebbistatin is a racemic mixture of (–)-blebbistatin and (+)-blebbistatin , the active and inactive forms, respectively. (–)-Blebbistatin is a selective cell-permeable inhibitor of non-muscle myosin II ATPases. (–)-Blebbistatin rapidly and reversibly inhibits Mg-ATPase activity and in vitro motility of non-muscle myosin IIA and IIB for several species (IC50s = 0.5-5 μM), while poorly inhibiting smooth muscle myosin (IC50 = 8 μM). Through these effects, (–)-blebbistatin blocks apoptosis-related bleb formation, directed cell migration, and cytokinesis in vertebrate cells. However, prolonged exposure to blue light (450-490 nm) results in degradation of blebbistatin to an inactive product via cytotoxic intermediates, which may be problematic for its use in fluorescent live cell imaging applications. (S)-nitro-Blebbistatin and (R)-nitro-blebbistatin are more stable forms of (–)-blebbistatin and (+)-blebbistatin, respectively. The addition of a nitro group stabilizes the molecules to circumvent their degradation by prolonged blue light exposure. (S)-nitro-Blebbistatin and (R)-nitro-blebbistatin have the same stereochemistry of the active and inactive enantiomers, respectively. | | Chemical Properties | Bright Yellow Solid | | Uses | 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.
(±)-1-Phenyl-1,2,3,4-tetrahydro-4-hydroxypyrrolo[2,3-b]-7-methylquinolin-4-one
Selective inhibitor of nonmuscle myosin II; 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.
| | Uses | (±)-Blebbistatin is a selective cell-permeable inhibitor of non-muscle myosin II ATPases. It rapidly and reversibly inhibits Mg-ATPase activity and in vitro motility of non-muscle myosin IIA and IIB for several species (IC50 = 0.5-5.0 μM), while poorly inhibiting smooth muscle myosin (IC50 = 80 μM). Through these effects, blebbistatin blocks apoptosis-related bleb formation, directed cell migration and cytokinesis in vertebrate cells. Blebbistatin is inactivated by UV light, which may be particularly important in fluorescent cell imaging applications. Purified enantiomers of Blebbistatin are also available from Cayman ((?)-Blebbistatin - ). | | Definition | ChEBI: A pyrroloquinoline that is 1,2,3,3a-tetrahydro-H-pyrrolo[2,3-b]quinolin-4-one substituted by a hydroxy group at position 3a, a methyl group at position 6 and a phenyl group at position 1. It acts as an inhibitor of ATPase ac
