Apafant

Description

WEB-2086 (105219-56-5) is a potent and selective antagonist of the platelet activating factor (PAF) receptor (Ki = 16.3 nM).1?Displays an activity profile which includes antiinflammatory, antiangiogenesis and anticancer activity.2?Along with leukotriene antagonists, WEB-2086 cooperatively provides a robust antiinflammatory effect regulating PMNL migration and edema formation.3?Displays analgesic effects in animal models of neuropathic pain.4?Active in vivo.
