The cytokine macrophage-migration inhibitory factor (MIF) has a broad range of pro-inflammatory effects in the innate and adaptive immune system. CIA’s lab has demonstrated the potential importance of MIF in the pathology of chronic inflammation via studies in models of rheumatoid arthritis (RA). Similarly to other chronic inflammatory diseases, MIF is overexpressed in human RA, and induces activation of key pathological processes in RA cells. Moreover, antagonism of MIF with mAb profoundly inhibits models of RA and other inflammatory diseases, confirming MIF as a therapeutic target in human inflammatory disease. The X-ray crystal structure of MIF has been published and the putative active site fully characterised. We have deduced structural features of MIF that reveal aspects of the structural complementarity of host-guest affinity. This information has been used in the synthesis of new compounds to antagonise MIF. We have designed, synthesised and tested several classes of compounds, which have shown activity from milli to nano-molar levels in novel in-house in vitro bioassays.
