Application

U-73122 hydrate has been used for studying the role of phospholipase C (PLC) signaling in modulating epithelial Na+ channel (ENaC) function in gerbil Reissner′s membranes (RMs). U-73122 has also been used to study local calcium responses in human umbilical vein endothelial cells (HUVECs).

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.

Features and Benefits

This compound is featured on the Phospholipase C page of the Handbook of Receptor Classification and Signal Transduction. To browse other handbook pages, click here.

Preparation Note

U-73122 hydrate is soluble in ethanol (approx. 0.7 mg/ml or ≤ 5 mg/ml with heating), chloroform (approx. 10 mg/ml) and DMSO (approx. 0.9 mg/ml or ≤ 2.6 mg/ml with heating). U-73122 hydrate is insoluble in water.

Stimulation of rat pancreatic acinar cells with low concentrations of phosphatidylinositol (PI)-linked secretagogues induces [Ca2+]i oscillations, without measurable changes in the formation of inositol 1,4,5-trisphosphate.

TRH increases cytosolic-free calcium ([Ca2+]i) by activating phospholipase C(PL-C), which induces phosphoinositol hydrolysis, leading to Ca2+ mobilization from inositol trisphosphate (IP3) sensitive stores, and by increasing Ca2+ influx. Increases in [Ca2+]i stimulate PRL secretion. We investigated the effects of U-73122
