title: Noncovalent thrombin inhibitors incorporating an imidazolylethynyl P1.
abstract: A series of noncovalent tripeptidic thrombin inhibitors incorporating a unidazolylethynyl moiety at P1 was investigated. A number of compounds of this series were highly potent and selective versus trypsin, and several compounds demonstrated good oral absorption in rats (F = 58% for compound 19).
