Biochem/physiol Actions

WEB 2086 inhibits PAF mediated chemotaxis and leukotriene C4 production in eosinophils. It prevents surge in airway resistance and cardiovascular side effects mediated by PAF inhalation.
WEB2086 is a very potent, selective platelet-activating factor (PAF) antagonist (IC50 = 16 nM). WEB2086 inhibits the proliferation of tumor cells and slows tumor growth in xenograft tumor models, and has been shown to inhibit angiogenesis.

Sodium-hydrogen exchanger (NHE), the principal sarcolemmal acid extruder in ventricular myocytes, is stimulated by a variety of autocrine/paracrine factors and contributes to myocardial injury and arrhythmias during ischemia-reperfusion. Platelet-activating factor (PAF; 1-o-alkyl-2-acetyl-sn-glycero-3-phosphocholine) is a potent proinflammatory phospholipid that is released
