Crystal structure of the catalytic region of human MASP-2 with specific inhibitor Analog 20
Structural highlights
DiseaseMASP2_HUMAN Defects in MASP2 are the cause of MASP2 deficiency (MASPD) [MIM:613791. MASPD is a disorder that results in autoimmune manifestations, recurrent severe infections, and chronic inflammatory disease.[1] [2] FunctionMASP2_HUMAN Serum protease that plays an important role in the activation of the complement system via mannose-binding lectin. After activation by auto-catalytic cleavage it cleaves C2 and C4, leading to their activation and to the formation of C3 convertase.[3] Publication Abstract from PubMedThe complement system of innate immunity recognizes, opsonizes, and kills invading pathogens and damaged cells, and stimulates an inflammatory response. Inappropriate or excessive complement activity is associated with a wide variety of pathological conditions, and several drugs targeting complement components have been approved. Here we describe the discovery and structure-activity relationships of a novel class of 2-aminoimidazole-containing inhibitors of mannan-binding lectin-associated serine proteases -2 and -3 (MASP-2 and MASP-3), essential enzymes for activation of the lectin and alternative pathways of complement, respectively. With a high degree of target selectivity and favorable in vitro pharmacological properties, this inhibitor series has the potential to be developed as treatments for numerous diseases and pathological conditions.
