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.

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.

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.

Microglia are implicated as a source of diverse proinflammatory factors in the CNS. Extracellular nucleotides are well known to be potent activators of glial cells and trigger the release of cytokines from microglia through purinergic receptors. However, little is known

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.

Exogenously administered cannabinoids are neuroprotective in several different cellular and animal models. In the current study, two cannabinoid CB1 receptor ligands (WIN 55,212-2, CP 55,940) markedly reduced hippocampal cell death, in a time-dependent manner, in cultured neurons subjected to high
