A new class of small-molecule GnRH antagonists, the thieno[2,3-b]pyrroles, was designed. Herein, the synthesis and structure-activity relationships are described. Substitution at the C4 position was investigated; during this study, it was observed that introducing piperazines and piperidines improved the physical properties of the compounds while retaining good in vitro potency. This exploration led to the discovery of amidopiperidines with improved pharmacokinetic properties. (c) 2007 Elsevier Ltd. All rights reserved.
