title: Design, synthesis and molecular modelling of 1-amidinopiperidine thrombin inhibitors.
abstract: Design, synthesis and biochemical evaluation of a series of novel non-covalent thrombin inhibitors with a 1-amidinopiperidine moiety are presented. Replacement of the planar benzamidine group in azaphenylalanine derivatives with 1-amidinopiperidine resulted in lower activity but higher selectivity for this type of compounds. The binding conformation of inhibitors in the active site of thrombin was revealed by molecular modelling studies.
