Actions biochimiques/physiologiques

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.

Activation of toll-like receptors (TLRs) and polymorphonuclear leukocyte (PMN) accumulation at infection sites are critical events of host defense. The involvement of leukotriene (LT) B(4) and platelet-activating factor (PAF) in TLR ligand-induced activation of inflammatory cell functions is essentially unknown.
