| Description | In neutrophils and human platelets, U-73122 inhibits agonist-induced phospholipase C (IC50=1.0-2.1 μM) activation. This compound affects the phospholipases by inhibiting the hydrolysis of PPI (phosphatidylinositol) to IP3 (inositol triphosphate), which in turn leads to a drop in cytosolic Ca2+. 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-73122 is useful as a negative control for investigations of U-73122 phospholipase C antagonism and its cellular consequences. | ||
