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 sepsis1. Inhibits airway remodeling in mouse asthma model2. ISO-1 also blocks MIF-induced autophagy3. Active in cellular and mouse models.
