Apafant Chemical Properties,Usage,Production

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.

Chemical Properties

White Solid

Uses

Platelet activating factor (PAF) antagonist.

Uses

Tool to evaluate the role of PAF in experimental models of human disease.

Definition

ChEBI: LSM-2613 is an organonitrogen heterocyclic compound and an organosulfur heterocyclic compound.

Biological Activity

Potent, selective platelet-activating factor (PAF) receptor antagonist (K i = 16.3 nM). Displays anti-inflammatory, antiangiogenic and anticancer activity. Inhibits growth and proliferation of MCF-7 breast cancer cells.

Biochem/physiol Actions

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.

storage

Desiccate at +4°C
