Hazard Information | Back Directory | [Description]
U-73122 is an inhibitor of PLC-dependent processes, however, the mechanism of action remains unclear. The IC50 values for inhibition of platelet aggregation induced by collagen or thrombin are 0.6 and 5 μM, respectively. It also exhibits inhibitory activity against HIV-1 integrase with an IC50 value of 7 μM. | [Uses]
It is used as a phospholipase C, phospholipase A2, and 5-LO inhibitor. It is also determined that in SK-N-SH neuroblastoma cells, U-73122 inhibits agonist-induced down-regulation of muscarinic receptors. In addition, it is a useful tool to investigate receptor-mediated PI turnover in signal transduction. U-73122 is a potent inhibitor of human neutrophil adhesion to biological surfaces (IC50 = 50 nM) as well as adhesion-dependent granule exocytosis and oxidative burst. U-73343 (sc-201422) is useful as a negative control for investigations of U-73122 phospholipase C antagonism and its cellular consequences. | [Definition]
ChEBI: An aza-steroid that is 3-O-methyl-17beta-estradiol in which the 17beta-hydroxy group is replaced by a 6-(maleimid-1-yl)hexylamino group. An inibitor of phospholipase C. | [Biological Activity]
Phospholipase C inhibitor. Inhibits agonist-induced platelet aggregation with IC 50 values of 1-5 μ M. Potently inhibits human polymorphonuclear neutrophil adhesion on biological surfaces (IC 50 < 50 nM) and exhibits antinociceptive activity in vivo . | [Biochem/physiol Actions]
Inhibits the hydrolysis of PPI to IP3, which leads to a decrease in cytosolic free calcium. Inhibits the coupling of G protein-phospholipase C activation, while remaining unaffected by production of cAMP. | [storage]
