General description

U-73343 is used to assess the involvement of G protein-coupled 1-phosphatidylinositol-phosphodiesterase or phospholipase C in receptor-mediated cell activation. It functions downstream of phospholipase C to block receptor-mediated phospholipase D activation.

Application

U-73343 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-73343 has also been used as a negative control for PLC inhibition in mechanically stimulated (MS) and its neighboring (NB) cells.
U-73343 has been used in measuring the fluorescence of intracellular Ca2+.

Biochem/physiol Actions

Inactive analog of U73122; used as a negative control.

Preparation Note

U-73343 is soluble in chloroform at 10 mg/ml and yields a clear, colorless to faint yellow solution. It is also soluble in ethanol (0.93 mg/ml) and DMSO (2.3 mg/ml), but is insoluble in water.

The effect of the environmental toxicant nonylphenol on cytosolic free Ca2+ concentration ([Ca2+]i) and proliferation has not been explored in human osteoblast-like cells. This study examined whether nonylphenol alters Ca2+ levels and causes cell death in MG63 human osteosarcoma cells.
