Abstract:
: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 Ki = 69 nM, which is ca. 15-fold less potent than constrained guanidine 5.
