Definition

An orally bioavailable inhibitor of the pro-inflammatory cytokine macrophage migration inhibitory factor (MIF), with potential anti-inflammatory, immunomodulating and antineoplastic activities. Upon oral administration, MIF inhibitor IPG1094 targets, binds to and inhibits the tautomerase activity of MIF. This attenuates the differentiation and infiltration of the immunosuppressive monocytic myeloid-derived suppressor cells (MDSCs) in the tumor microenvironment (TME), which results in an enhanced immune response against tumor cells and the inhibition of tumor cell proliferation. MIF, overexpressed in some cancers, plays a key role in inflammation, regulation of the immune response and cancer cell proliferation. IPG1094 is able to penetrate the blood-brain barrier (BBB).
