Abstract

The discovery and characterization of a novel chemical series of phosphorothioyl-containing imidazopyridines as potent neuropeptide S receptor antagonists is presented. The synthesis of analogues and their structure-activity relationship with respect to the Gq, Gs, and ERK pathways is detailed. The pharmacokinetics and in vivo efficacy of a potent analogue in a food intake rodent model are also included, underscoring its potential therapeutic value for the treatment of sleep, anxiety, and addiction disorders.
