4,5-Dihydro-3-phenyl-5-isoxazoleaceticacid Chemical Properties,Usage,Production

Description

VGX-1027 (6501-72-0) is an immunomodulator that inhibits secretion of IL-1β, TNF-α, and IL-10 from murine macrophages stimulated with LPS and spares T cell function.1?Ameliorates the course of acute and chronic immunoinflammatory conditions such as carrageenan-induced pleurisy, LPS-induced lethality, and type II collagen-induced arthritis in mouse models.1?Prevents spontaneous and accelerated forms of autoimmune diabetes in a NOD mouse model.2?Modulates genes involved in LPS-induced Toll-like receptor 4 activation in a mouse Lupus model.3?Displays protective effects in particulate matter-induced acute lung injury by blocking TLR4 signaling.4

Uses

2-(3-Phenyl-4,5-dihydroisoxazol-5-yl)acetic Acid reduces the secretion of IL-1β, TNF-α and IL-10 from purified murine macrophages but not of T cells; and reduces the activation of NF-κB and p38 MAP kinase pathways along with up-regulation of ERK pathways. 2-(3-Phenyl-4,5-dihydroisoxazol-5-yl)acetic Acid inhibits proliferation of enterobacterial antigen-reactive CD4+CD25- T cells in vitro .

storage

Store at +4°C
