Abstract
The oxytocin receptor (OTR) plays a major role in the control of male sexual responses. Antagonists of the OTR have been reported to inhibit ejaculation in animal models and serve as a potential treatment for premature ejaculation (PE). Herein, we describe a novel scaffold featuring an aryl substituted 3-azabicyclo [3.1.0] hexane structure. The lead compound, SHR1653, was shown to be a highly potent OTR antagonist, which exhibited excellent selectivity over V1AR, V1BR, and V2R. This novel molecule was shown to have a favorable pharmacokinetic profile across species, as well as robust in vivo efficacy in a rat uterine contraction model. Interestingly, SHR1653 exhibited excellent blood-brain barrier penetration, which might be beneficial for the treatment of CNS-related PE.
