ABSTRACT
Design, synthesis, and structure-activity relationships of thieno[2,3-b]pyridin-4-one-based non-peptide luteinizing hormone-releasing hormone (LHRH) receptor antagonists are described. Starting with the thienopyridin-4-one derivative 26d (T-98475) an optimization study was performed, which resulted in the identification of a highly potent and orally bioavailable LHRH receptor antagonist, 3-(N-benzyl-N-methylaminomethyl)-7-(2,6-difluorobenzyl)-4,7-dihydro-2-[4-(1-hydroxy-1-cyclopropanecarboxamido)phenyl]-5-isobutyryl-4-oxothieno[2,3-b]pyridine (33c). Compound 33c displayed subnanomolar in vitro activities for the human receptor and its oral administration caused effective suppression of the plasma LH levels in castrated male cynomolgus monkeys. Furthermore, SAR studies revealed that a hydroxyalkylamido moiety on the 2-phenyl ring is virtually equivalent to an alkylureido moiety, at least in this series of compounds.
