Function

CBPB2_HUMAN Cleaves C-terminal arginine or lysine residues from biologically active peptides such as kinins or anaphylatoxins in the circulation thereby regulating their activities. Down-regulates fibrinolysis by removing C-terminal lysine residues from fibrin that has already been partially degraded by plasmin.[1]

Publication Abstract from PubMed

A series of 4,5,6,7-tetrahydro-1H-benzimidazole-5-carboxylic acid and 5,6,7,8-tetrahydroimidazo[1,2-a]pyridine-7-carboxylic acid derivatives designed as inhibitors of TAFIa has been prepared via a common hydrogenation-alkylation sequence starting from the appropriate benzimidazole and imidazopyridine system. We present a successful design strategy using a conformational restriction approach resulting in potent and selective inhibitors of TAFIa. The X-ray structure of compound 5 in complex with a H333Y/H335Q double mutant TAFI indicate that the conformational restriction is responsible for the observed potency increase.
