摘要:
We expand the structural requirements and structure-activity relationship of a novel class of non-peptidic aryl-based thrombin inhibitors through exploration of the S1 specificity pocket of thrombin using flexible and constrained amidines. The most active compound of this class is 11 with K-i = 69 nM, which is ca. 15-fold less potent than constrained guanidine 5. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
