Identification of MK-8133: An orexin-2 selective receptor antagonist with favorable development properties
摘要:
Antagonism of orexin receptors has shown clinical efficacy as a novel paradigm for the treatment of insomnia and related disorders. Herein, molecules related to the dual orexin receptor antagonist filorexant were transformed into compounds that were selective for the OX2R subtype. Judicious selection of the substituents on the pyridine ring and benzamide groups led to 6b; which was highly potent, OX2R selective, and exhibited excellent development properties.

1-acyl-2-benzylpyrrolidines were discovered as potent and competitive dualorexinreceptorantagonists. Metabolic stability was improved to afford oral exposure, and aqueous solubility was increased by twentyfold, providing compounds suitable for preclinical evaluation. Compound 27 showed insurmountable antagonism at both orexin 1 and orexin 2 receptor subtypes and displayed a comparable sleep-promoting
