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). Abolishes T lymphoma cell invasion into fibroblast monolayers.

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
Warning
Toxicity: Irritant (B)
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.
Reconstitution
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.

Abnormal calcium homeostasis, activation of protease calpain, generation of p25 and hyperactivation of cyclin-dependent kinase 5 (Cdk5) have all been implicated in the pathogenesis of neurogenerative diseases including Alzheimer's disease.
