478336-92-4

ISO-1 (478336-92-4) is an antagonist of macrophage migration inhibitory factor (MIF, a pro-inflammatory cytokine). Displays anti-inflammatory activity. Increases survival in severe sepsis.1 Inhibits airway remodeling in mouse asthma model.2 ISO-1 also blocks MIF-induced autophagy.3?Active in cellular and mouse models.

MIF Antagonist, ISO-1 inhibits MIF dopachrome tautomerase activity by binding to its catalytic active site (IC50 = 7 μM for D-dopachrome tautomerase) and suppresses the production of TNFα, PGE2 and COX-2 in human monocytes and arachidonic acid in RAW 264.7 macrophages. MIF Antagonist, ISO-1 has been shown to exhibit antidiabetogenic properties in immunoinflammatory diabetic mouse model.
