Unusual pyrimidine participation: efficient stereoselective synthesis of potent dual orexin receptor antagonist MK-6096.[Pubmed:25365229]
Org Lett. 2014 Nov 21;16(22):5890-3.
An asymmetric synthesis of dual orexin receptor antagonist MK-6096 (1) is described. Key steps for the trans-2,5-disubstituted piperidinyl ether fragment include a biocatalytic transamination, a trans-selective Mukaiyama aldol, and a regioselective pyridyl SNAr process. The pyrimidyl benzoic acid was synthesized via a Negishi coupling and a nitrile hydrolysis. Coupling of the two fragments via a catalytic T3P-mediated amidation completed the synthesis. Unusual behaviors in the hydrolysis of pyrimidyl benzonitrile and the amide coupling of the pyrimidyl benzoic acid are also described.
Pharmacological characterization of MK-6096 - a dual orexin receptor antagonist for insomnia.[Pubmed:22019562]
Neuropharmacology. 2012 Feb;62(2):978-87.
Orexin (hypocretin) neuropeptides promote wakefulness by signaling through two G-protein coupled receptors, Orexin 1 Receptor (OX(1)R) and Orexin 2 Receptor (OX(2)R). MK-6096 is an orally bioavailable potent and selective reversible antagonist of OX(1)R and OX(2)R currently in clinical development for insomnia. In radioligand binding and functional cell based assays MK-6096 demonstrated potent binding and antagonism of both human OX(1)R and OX(2)R (<3 nM in binding, 11 nM in FLIPR), with no significant off-target activities against a panel of >170 receptors and enzymes. MK-6096 occupies 90% of human OX(2)Rs expressed in transgenic rats at a plasma concentration of 142 nM, and dose-dependently reduced locomotor activity and significantly increased sleep in rats (3-30 mg/kg) and dogs (0.25 and 0.5 mg/kg). DORA-22, an analog of MK-6096, exhibits similar sleep promoting properties that are absent OX(1/2)R double knockouts, demonstrating the mechanism of action and specificity of these effects. These findings with a novel, structurally distinct class of OxR antagonists provide further validation of the orexin pathway as an effective target to promote normal sleep. Comparative analysis of the biochemical and pharmacokinetic properties of these compounds relative to other OXR antagonists provides a basis for understanding the attributes critical for in vivo efficacy. This mechanism is distinct from current standard of care such that MK-6096 represents a novel and selective therapeutic for the treatment of insomnia. This article is part of a Special Issue entitled 'Post-Traumatic Stress Disorder'.
A Phase II Dose-Ranging Study Evaluating the Efficacy and Safety of the Orexin Receptor Antagonist Filorexant (MK-6096) in Patients with Primary Insomnia.[Pubmed:26979830]
Int J Neuropsychopharmacol. 2016 Aug 12;19(8). pii: pyw022.
BACKGROUND: Filorexant (MK-6096) is an orexin receptor antagonist; here, we evaluate the efficacy of filorexant in the treatment of insomnia in adults. METHODS: A double-blind, placebo-controlled, randomized, two 4-week-period, adaptive crossover polysomnography study was conducted at 51 sites worldwide. Patients (18 to <65 years) with insomnia received 1 of 4 doses of oral filorexant (2.5, 5, 10, 20mg) once daily at bedtime during one period and matching placebo in the other period in 1 of 8 possible treatment sequences. Polysomnography was performed on night 1 and end of week 4 of each period. The primary endpoint was sleep efficiency at night 1 and end of week 4. Secondary endpoints included wakefulness after persistent sleep onset and latency to onset of persistent sleep. RESULTS: A total of 324 patients received study treatment, 315 received >/=1 dose of placebo, and 318 >/=1 dose of filorexant (2.5mg, n=79; 5mg, n=78; 10mg, n=80; 20mg, n=81). All filorexant doses (2.5/5/10/20mg) were significantly superior to placebo in improving sleep among patients with insomnia as measured by sleep efficiency and wakefulness after persistent sleep onset on night 1 and end of week 4. The 2 higher filorexant doses (10/20mg) were also significantly more effective than placebo in improving sleep onset as measured by latency to onset of persistent sleep at night 1 and end of week 4. Filorexant was generally well tolerated. CONCLUSIONS: Orexin receptor antagonism by filorexant significantly improved sleep efficiency in nonelderly patients with insomnia. Dose-related improvements in sleep onset and maintenance outcomes were also observed with filorexant.
Discovery of [(2R,5R)-5-{[(5-fluoropyridin-2-yl)oxy]methyl}-2-methylpiperidin-1-yl][5-methyl-2 -(pyrimidin-2-yl)phenyl]methanone (MK-6096): a dual orexin receptor antagonist with potent sleep-promoting properties.[Pubmed:22307992]
ChemMedChem. 2012 Mar 5;7(3):415-24, 337.
Insomnia is a common disorder that can be comorbid with other physical and psychological illnesses. Traditional management of insomnia relies on general central nervous system (CNS) suppression using GABA modulators. Many of these agents fail to meet patient needs with respect to sleep onset, maintenance, and next-day residual effects and have issues related to tolerance, memory disturbances, and balance. Orexin neuropeptides are central regulators of wakefulness, and orexin antagonism has been identified as a novel mechanism for treating insomnia with clinical proof of concept. Herein we describe the discovery of a series of alpha-methylpiperidine carboxamide dual orexin 1 and orexin 2 receptor (OX(1) R/OX(2) R) antagonists (DORAs). The design of these molecules was inspired by earlier work from this laboratory in understanding preferred conformational properties for potent orexin receptor binding. Minimization of 1,3-allylic strain interactions was used as a design principle to synthesize 2,5-disubstituted piperidine carboxamides with axially oriented substituents including DORA 28. DORA 28 (MK-6096) has exceptional in vivo activity in preclinical sleep models, and has advanced into phase II clinical trials for the treatment of insomnia.
