Description générale

(-)-Blebbistatin, a bioactive small molecule, is a selective inhibitor of skeletal muscle and non-muscle myosin II isoforms.The mechanism of action of blebbistatin, a myosin II ATPase inhibitor, does not influence other members of the myosin superfamily, such as 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.Blebbistatin’s selectivity and affinity for multiple class II myoisin make it an attractive candidate for use in cell motility research and muscle physiology.

Application

(−)-Blebbistatin has been used to investigate the effect on cardiac contractility and effect of thrombin on actomyosin contractility

Actions biochimiques/physiologiques

(-)-Blebbistatin is a cell cycle inhibitor; selective inhibitor of non-muscle myosin II.

Three-dimensional matrices often contain highly structured adhesive tracks that require cells to turn corners and bridge non-adhesive areas. Here, we investigate these complex processes using micropatterned cell adhesive frames. Spreading kinetics on these matrices depend strongly on initial adhesive position

Discover Bioactive Small Molecules for Apoptosis

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.

Discover Bioactive Small Molecules for Cell Cycle Research

n proliferating cells, the cell cycle consists of four phases. Gap 1 (G1) is the interval between mitosis and DNA replication that is characterized by cell growth. Replication of DNA occurs during the synthesis (S) phase, which is followed by a second gap phase (G2) during which growth and preparation for cell division occurs. Together, these three stages comprise the interphase phase of the cell cycle. Interphase is followed by the mitotic (M) phase.
