THROMBIN-METHOXY2
Overview
Two series of tricyclic inhibitors of the serine protease thrombin, imides, (+/-)-1-(+/-)-8 and lactams (+/-)-9-(+/-)-13, were analysed to evaluate, contributions of orthogonal multipolar interactions with the backbone C=O, moiety of Asn98 to the free enthalpy of protein-ligand complexation. The, lactam derivatives are much more potent and more selective inhibitors, (K(i) values between 0.065 and 0.005 microM, selectivity for thrombin over, trypsin between 361- and 1609-fold) than the imide compounds (Ki values, between 0.057 and 23.7 microM, selectivity for thrombin over trypsin, between 3- and 67-fold). The increase in potency and selectivity is, explained by the favorable occupancy of the P-pocket of thrombin by the, additional isopropyl substituent in the lactam derivatives. The ...
