Overview

Information

ISO-1 ISO-1 (MIF Antagonist) is an inhibitor of MIF (Macrophage migration inhibitory factor) D-dopachrome tautomerase activity with an IC50 of ~7 μM.
In vitro

ISO-1 significantly inhibits the cytokine activity in vitro. It inhibits tumor necrosis factor release from macrophages isolated from LPStreated wild type mice but has no effect on cytokine release from MIF-deficient macrophages.

In vivo

ISO-1 significantly increases the survival rate in severe sepsis induced by endotoxin or cecal ligation and puncture (CLP). It could prevent airway hyperresponsiveness (AHR) in mouse ovalbumin (OVA)-challenge models. ISO-1 attenuated ozone-induced cell recruitment, cytokine release and AHR in the mouse but did not affect measures of emphysema. ISO-1 protects photoreceptors and reduces gliosis in experimental retinal detachment.
