Immunopharmacology Comments
Carotegrast methyl (AJM300) is a small-molecule anti-integrin prodrug. Its active metabolite, carotegrast, produces the same functional outcome as the anti-α4 antibody natalizumab, but with the benefits associated with small-molecule drugs [2-4]. Specifically, carotegrast blocks interactions between α4β1 and α4β7 integrins with their counter-receptors (VCAM-1 and MAdCAM-1 respectively) and fibronectin, and this mechanism limits transmigration of leukocytes into sites of inflammation.
