A series of noncovalent tripeptidic thrombin inhibitors incorporating amidrazone, amine and amidine functions at PI was investigated. While the amidrazone and the amine series displayed limited oral absorption, the amidine series demonstrated generally good oral absorption and strong antithrombotic activity; the single-digit picomolar K-i achieved from this series is among the best yet reported. The present work highlights the benzamidine compound 11f (LB30812) that exhibits excellent overall profiles of potency, oral absorption and antithrombotic efficacy. (C) 2002 Elsevier Science Ltd.
