BOVINE TRYPSIN WITH 1-[2-[5-[AMINO(IMINO)METHYL]-2-HYDROXYPHENOXY]-6-[3-(4,5-DIHYDRO-1-METHYL-1H-IMIDAZOL-2-YL)PHENOXY]PYRIDIN-4-YL]PIPERIDINE-3-CARBOXYLIC ACID (ZK-806974)
OverviewOverview
Factor Xa is a serine protease which activates thrombin (factor IIa) and, plays a key regulatory role in the blood-coagulation cascade. Factor Xa, is, therefore, an important target for the design of anti-thrombotics., Both factor Xa and thrombin share sequence and structural homology with, trypsin. As part of a factor Xa inhibitor-design program, a number of, factor Xa inhibitors were crystallographically studied complexed to bovine, trypsin. The structures of one diaryl benzimidazole, one diaryl carbazole, and three diaryloxypyridines are described. All five compounds bind to, trypsin in an extended conformation, with an amidinoaryl group in the S1, pocket and a second basic/hydrophobic moiety bound in the S4 pocket. These, binding modes all bear a resemblance to the reported binding mode of, DX-9065a in bovine trypsin and human factor Xa.
