MK-3697

• Description:

  MK-3697 is an isonicotinamide small molecule, acting as a potent and selective Orexin 2 receptor antagonist with Ki = 0.95 nM. IC50 value: 0.95 nM (Ki) Target: Orexin 2 receptor antagonist MK-3697 is a highly potent, orally bioavailable selective orexin 2 receptor antagonists (2-SORAs) that possess acceptable profiles for clinical development. Herein we report additional SAR studies within the “triaryl” amide 2-SORA series focused on improvements in compound stability in acidic media and time-dependent inhibition of CYP3A4. MK-3697 has improved stability and TDI profiles as well as excellent sleep efficacy across species.
