Opis

General description

A potent, selective, and cell-permeable inhibitor C-type phosphatidylinositol-specific phospholipases. Inhibits agonist-induced phospholipase C activation (IC₅₀ = 1-2.1 µM) in human platelets and neutrophils. Inhibits ET-1 and parathyroid hormone-induced Ca²⁺ transients (IC₅₀ = 800 nM and 500 nM, respectively). Also inhibits agonist-induced down-regulation of muscarinic receptors in SK-N-SH neuroblastoma cells. Acts as a potent inhibitor of human polymorphonuclear neutrophil adhesion on biological surfaces (IC₅₀ = 50 nM). Reported to abolish T lymphoma cell invasion into fibroblast monolayers.

Biochem/physiol Actions

Cell permeable: yes

Primary Target
Agonist-induced phospholipase C activation

Product does not compete with ATP.

Reversible: no

Target IC₅₀: 1-2.1 µM against agonist-induced phospholipase C activation in human platelets and neutrophils; 800 nM and 500 nM, respectively, against ET-1 and parathyroid hormone-induced Ca2+ transients; 50 nM against human polymorphonuclear neutrophil adhesion

Preparation Note

The use of anhydrous solvents is critical for the solubility of the compound; the presence of moisture in the solvent will lower the solubility of the compound.

Unstable in DMSO and ethanol; reconstitute in anhydrous DMSO or ethanol just prior to use. Following reconstitution in anhydrous chloroform, aliquot into single use volumes, evaporate to dryness under a stream of nitrogen, and freeze (-20°C. Dried aliquots are stable for up to 6 months at -20°C. ); Reconstitute dried aliquots in anhydrous DMSO or anhydrous ethanol just prior to use.
