BAY 2925976 is a novel oral ARα2C antagonist developed by Bayer for the treatment of OSA (obstructive sleep apnea), a widespread condition affecting nearly one billion people globally. Despite the availability of mechanical treatments like CPAP, poor adherence rates highlight the need for more effective interventions. BAY 2925976 demonstrated a preclinical proof of concept for ARα₂C modulation as a potential therapeutic approach for OSA. In this article, we detail the discovery of BAY 2925976, as highlighted by Michael Hahn at the ACS Fall 2024 First-Time Disclosures session in Denver, CO.
