TECHNICAL FIELD
The present invention is directed to substituted 7-azabicyclic compounds, pharmaceutical compositions comprising them, methods of making them, and methods of using them for the modulation of the orexin receptor for the treatment of disease states, disorders, and conditions mediated by orexin receptor activity.
BACKGROUND
Orexin/hypocretin signaling is mediated by two receptors and two peptide agonists. The peptides (orexin-A and orexin-B) are cleavage products of the same gene, pre-pro orexin. In the central nervous system, neurons producing pre-pro orexin are found solely in the perifornical nucleus, the dorsal hypothalamus, and the lateral hypothalamus (Peyron et al., 1998, J. Neurosci. 18: 9996-10015). Orexigenic cells in these regions project to many areas of the brain, extending rostrally to the olfactory bulbs and caudally to the spinal cord (Van den Pol, 1999, J. Neurosci. 19: 3171-3182).
The orexins bind to two high affinity receptors, referred to as orexin-1 and orexin-2 receptors. Orexin-1 and orexin-2 receptors are G-protein-coupled, seven transmembrane receptors that share over 64% amino acid sequence identity with one another. Both receptors are generally excitatory, the common cellular response to orexin-induced receptor activation being increases in intracellular calcium. Homology between the species orthologs is high and there are no known pharmacological differences. Orexin-A and -B are usually considered equal ligands for orexin-2 receptor but orexin-B is thought to be 5- to 100-fold weaker ligand than orexin-A at the orexin-1 receptor (Sakurai et al., 1998, Cell 92: 573-585; Ammoun et al., 2003, J. Pharmacol. Exp. Ther. 305: 507-514).
Many regions of the brain have fairly selective expression of the orexin-1 or orexin-2 receptors (Marcus et al., 2001, 1 Comp Neurology 435, 6-25; Trivedi et al., 1998, FEBS Letters, 438, 71-75). Orexin-1 receptors are selective for the limbic system (bed nucleus of the stria terminalis and amygdala), cingulate cortex and noradrenergic neurons in the locus coeruleus. Conversely, the orexin-2 receptor is almost the exclusive orexin receptor in the histaminergic neurons in the tuberomammilary nucleus which play a critical role in wake promotion; in paraventricular neurons and the parabrachial nucleus. In other brain regions like the dorsal raphe, the ventral tegmental area or the prefontal cortex both receptors are coexpressed.
The broad CNS distribution of cells producing orexin, as well as cells expressing the orexin receptors, suggests involvement of orexin in a number of physiological functions, including feeding and metabolism, regulation of wakefulness and sleep, sympathetic activation and stress response (de Lecea, 2012, Progress in Brain Research, 198, 15-24; Kukkonen, 2013, Am J. Physiol. Cell Physiol., 304, C2-C32). Orexin also plays a key role regulating motivation and reward associated with food intake and with drugs of abuse (Mahler et al., 2012, Progress in Brain Research, 198, 79-121).
Several lines of evidence indicate that the orexin system is an important modulator of arousal. Rodents administered orexin intracerebroventricularly spend more time awake (Piper et al., 2000, J. Neurosci. 12: 726-730. Orexin-mediated effects on arousal have been linked to orexin neuronal projections to histaminergic neurons in the tuberomammillary nucleus (Yamanaka et al., 2002, Biochem. Biophys. Res. Comm. 290: 1237-1245). Rodents whose pre-pro orexin gene has been knocked out, or whose orexigenic neurons have been killed, display altered sleep/wake cycles similar to narcolepsy (Chemelli et al., 1999, Cell 98: 437-451; Hara et al., 2001, Neuron 30: 345-354). Dog models of narcolepsy have been shown to have mutant or non-functional orexin-2 receptors (Lin et al., 1999, Cell 98: 365-376). Orexin signaling as a target for sleep-promoting therapies was further validated clinically by findings of attenuated orexin levels and loss of orexinergic neurons in human narcoleptic patients (Mignot et al., 2001, Am. J. Hum. Genet. 68: 686-699; Minot & Thorsby, 2001, New England J. Med. 344: 692) or, in rare cases, to mutations in the orexin-2 gene (Peyron et al., 2000, Nature Med. 6: 991-997). Disorders of the sleep-wake cycle are therefore likely targets for orexin-2 receptor modulator activity. Examples of sleep-wake disorders that may be treated by agonists or other modulators that up-regulate orexin-2 receptor-mediated processes include narcolepsy, jet lag (sleepiness) and sleep disorders secondary to neurological disorders such as depression. Examples of disorders that may be treated by antagonists or other modulators that down-regulate orexin-2 receptor-mediated processes include insomnia, restless leg syndrome, jet lag (wakefulness) and sleep disorders secondary to neurological disorders such as mania, schizophrenia, pain syndromes and the like.
Evidence has accumulated to demonstrate a clear involvement of orexin signaling in reward pathways associated with drug dependence (Mahler et al., 2012, Progress in Brain Research, 198, 79-121). Orexinergic neurons send projections to the ventral tegmental area and other brain regions involved in reward processing. Orexin ligands mediate reward behavior, and antagonizing these effects with a selective orexin-1 receptor antagonist in various preclinical model of addiction has suggested that these actions are mediated through orexin-1 receptor. Specifically, a selective orexin-1 antagonist attenuates morphine conditioned place preference and reinstatement (Harris et al., 2005, Nature, 437, 556-5599; Narita et al., 2006, J Neurosci., 26, 398-405; Harris et al., 2007, Behav Brain Res, 183, 43-51), stress-induced cocaine reinstatement, cocaine-induced behavioral and synaptic plasticity (Borgland et al., 2006, Neuron, 49, 589-601), and intake and cue and stress-induced reinstatement of ethanol (Lawrence et al., 2006, Br J Pharmacol, 148, 752-759), in addition to attenuating precipitated morphine withdrawal (Sharf et al., 2008, Biol Psychiatry, 64, 175-183) and nicotine self-administration (Hollander et al., 2008, Proc Natl Acad Sci USA., 105, 19480-19485). Another recent study has also suggested a role for OX2R (Shoblock et al., 2011, Psychopharmacology, 215, 191-203).
Orexin's role in more complex emotional behavior is also emerging (Johnson et al., 2012, Progress in Brain Research, 198, 133-161). Changes in orexin levels in patients with panic and posttraumatic stress disorders have been noted as have changes in the prevalence of anxiety behaviors in narcoleptic patients (Johnson et al., 2010, Nature Medicine, 16, 111-115; Fortuyn et al., 2010, General Hospital Psychiatry, 32, 49-56; Strawn et al., 2010, Psychoneuroendocrinology, 35, 1001-1007). Lactate infusion or acute hypercapnia, which causes panic in humans, and are used as an animal model of panic, activates orexin neurons in the perifornical hypothalamus. This activation correlates with anxiety in the social interaction test or open field test. Blocking orexin signaling with either siRNA or selective orexin-1 receptor antagonists attenuates panic-like responses to lactate (Johnson et al., 2010, Nature Medicine, 16, 111-115; Johnson et al., 2012, Neuropsychopharmacology, 37, 1911, 1922).
Cerebral spinal fluid (CSF) levels of orexin are lower in depressed or suicidal patients, and the level of orexin inversely correlates with illness severity (Brundin et al., 2007, European Neuropsychopharmacology, 17, 573-579; Salomon et al., 2003, Biol Psychiatry, 54, 96-104). A positive correlation between orexin-1 receptor mRNA in the amygdala and depressive behavior in the forced swim test in mice has been reported (Arendt, 2013, Behavioral Neuroscience, 127, 86-94).
The orexin system also interacts with brain dopamine systems. Intracerebroventricular injections of orexin in mice increase locomotor activity, grooming and stereotypy; these behavioral effects are reversed by administration of D2 dopamine receptor antagonists (Nakamura et al., 2000, Brain Res. 873: 181-187). Therefore, orexin receptor modulators may be useful to treat various neurological disorders; e.g., agonists or up-regulators to treat catatonia, antagonists or down-regulators to treat Parkinson's disease, Tourette's syndrome, anxiety, delirium and dementias.
Orexins and their receptors have been found in both the myenteric and submucosal plexus of the enteric nervous system, where orexins have been shown to increase motility in vitro (Kirchgessner & Liu, 1999, Neuron 24: 941-951) and to stimulate gastric acid secretion in vitro (Takahashi et al., 1999, Biochem. Biophys. Res. Comm. 254: 623-627). Orexin effects on the gut may be driven by a projection via the vagus nerve (van den Pol, 1999, supra), as vagotomy or atropine prevent the effect of an intracerebroventricular injection of orexin on gastric acid secretion (Takahashi et al., 1999, supra). Orexin receptor antagonists or other down-regulators of orexin receptor-mediated systems are therefore potential treatments for ulcers, irritable bowel syndrome, diarrhea and gastroesophageal reflux.
Body weight may also be affected by orexin-mediated regulation of appetite and metabolism. Some effects of orexin on metabolism and appetite may be mediated in the gut, where, as mentioned, orexins alter gastric motility and gastric acid secretion. Orexin antagonists therefore are likely to be useful in treatment of overweight or obesity and conditions related to overweight or obesity, such as insulin resistance/type II diabetes, hyperlipidemia, gallstones, angina, hypertension, breathlessness, tachycardia, infertility, sleep apnea, back and joint pain, varicose veins and osteoarthritis. Conversely, orexin agonists are likely to be useful in treatment of underweight and related conditions such as hypotension, bradycardia, amenorrhea and related infertility, and eating disorders such as anorexia and bulimia.
Intracerebroventricularly administered orexins have been shown to increase mean arterial pressure and heart rate in freely moving (awake) animals (Samson et al., 1999, Brain Res. 831: 248-253; Shirasaka et al., 1999, Am. J. Physiol. 277: R1780-R1785) and in urethane-anesthetized animals (Chen et al., 2000, Am. J. Physiol. 278: R692-R697), with similar results. Orexin receptor agonists may therefore be candidates for treatment of hypotension, bradycardia and heart failure related thereto, while orexin receptor antagonists may be useful for treatment of hypertension, tachycardia and other arrhythmias, angina pectoris and acute heart failure.
From the foregoing discussion, it can be seen that the identification of orexin receptor modulators, will be of great advantage in the development of therapeutic agents for the treatment of a wide variety of disorders that are mediated through these receptor systems.

“Pharmaceutically acceptable vehicle” refers to a diluent, adjuvant, excipient or carrier with which a compound of the invention is administered. A “pharmaceutically acceptable excipient” refers to a substance that is non-toxic, biologically tolerable, and otherwise biologically suitable for administration to a subject, such as an inert substance, added to a pharmacological composition or otherwise used as a vehicle, carrier, or diluent to facilitate administration of agent and that is compatible therewith. Examples of excipients include calcium carbonate, calcium phosphate, various sugars and types of starch, cellulose derivatives, gelatin, vegetable oils, and polyethylene glycols.
“Subject” includes humans. The terms “human,” “patient,” and “subject” are used interchangeably herein.
“Treating” or “treatment” of any disease or disorder refers, in one embodiment, to ameliorating the disease or disorder (i.e., arresting or reducing the development of the disease or at least one of the clinical symptoms thereof). In another embodiment “treating” or “treatment” refers to ameliorating at least one physical parameter, which may not be discernible by the subject. In yet another embodiment, “treating” or “treatment” refers to modulating the disease or disorder, either physically, (e.g., stabilization of a discernible symptom), physiologically, (e.g., stabilization of a physical parameter), or both. In yet another embodiment, “treating” or “treatment” refers to delaying the onset of the disease or disorder.
“Compounds of the present invention,” and equivalent expressions, are meant to embrace compounds of the Formula (I) as described herein, which expression includes the pharmaceutically acceptable salts, and the solvates, e.g., hydrates, where the context so permits. Similarly, reference to intermediates, whether or not they themselves are claimed, is meant to embrace their salts, and solvates, where the context so permits.
As used herein, the term “isotopic variant” refers to a compound that contains unnatural proportions of isotopes at one or more of the atoms that constitute such compound. For example, an “isotopic variant” of a compound can be radiolabeled, that is, contain one or more non-radioactive isotopes, such as for example, deuterium (2H or D), carbon-13 (13C), nitrogen-15 (15N), or the like. It will be understood that, in a compound where such isotopic substitution is made, the following atoms, where present, may vary, so that for example, any hydrogen may be 2H/D, any carbon may be 13C, or any nitrogen may be 15N, and that the presence and placement of such atoms may be determined within the skill of the art. Likewise, the invention may include the preparation of isotopic variants with radioisotopes, in the instance for example, where the resulting compounds may be used for drug and/or substrate tissue distribution studies. Radiolabeled compounds of the invention can be used in diagnostic methods such as Single-photon emission computed tomography (SPECT). The radioactive isotopes tritium, i.e. 3H, and carbon-14, i.e. 14C, are particularly useful for their ease of incorporation and ready means of detection. Further, compounds may be prepared that are substituted with positron emitting isotopes, such as 11C, 18F, 15O and 13N, and would be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy.
All isotopic variants of the compounds of the invention, radioactive or not, are intended to be encompassed within the scope of the invention.
It is also to be understood that compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed “isomers.” Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers.”
Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers.” When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture.”
“Tautomers” refer to compounds that are interchangeable forms of a particular compound structure, and that vary in the displacement of hydrogen atoms and electrons. Thus, two structures may be in equilibrium through the movement of π electrons and an atom (usually H). For example, enols and ketones are tautomers because they are rapidly interconverted by treatment with either acid or base. Another example of tautomerism is the aci- and nitro-forms of phenyl nitromethane, that are likewise formed by treatment with acid or base.
Tautomeric forms may be relevant to the attainment of the optimal chemical reactivity and biological activity of a compound of interest.
Compounds of the invention may also exist as “rotamers,” that is, conformational isomers that occur when the rotation leading to different conformations is hindered, resulting a rotational energy barrier to be overcome to convert from one conformational isomer to another.
The compounds of this invention may possess one or more asymmetric centers; such compounds can therefore be produced as individual (R)- or (S)-stereoisomers or as mixtures thereof.

Neurological disorders include, but are not limited to, Parkinson's disease, Alzheimer's disease, Tourette's Syndrome, catatonia, anxiety, delirium and dementias.
In treatment methods according to the invention, an effective amount of a pharmaceutical agent according to the invention is administered to a subject suffering from or diagnosed as having such a disease, disorder, or condition. An “effective amount” means an amount or dose sufficient to generally bring about the desired therapeutic or prophylactic benefit in patients in need of such treatment for the designated disease, disorder, or condition. Effective amounts or doses of the compounds of the present invention may be ascertained by routine methods such as modeling, dose escalation studies or clinical trials, and by taking into consideration routine factors, e.g., the mode or route of administration or drug delivery, the pharmacokinetics of the compound, the severity and course of the disease, disorder, or condition, the subject's previous or ongoing therapy, the subject's health status and response to drugs, and the judgment of the treating physician. An example of a dose is in the range of from about 0.001 to about 200 mg of compound per kg of subject's body weight per day, preferably about 0.05 to 100 mg/kg/day, or about 1 to 35 mg/kg/day, in single or divided dosage units (e.g., BID, TID, QID). For a 70-kg human, an illustrative range for a suitable dosage amount is from about 0.05 to about 7 g/day, or about 0.2 to about 2.5 g/day.
Once improvement of the patient's disease, disorder, or condition has occurred, the dose may be adjusted for preventative or maintenance treatment. For example, the dosage or the frequency of administration, or both, may be reduced as a function of the symptoms, to a level at which the desired therapeutic or prophylactic effect is maintained. Of course, if symptoms have been alleviated to an appropriate level, treatment may cease. Patients may, however, require intermittent treatment on a long-term basis upon any recurrence of symptoms.
In addition, the compounds of the invention may be used in combination with additional active ingredients in the treatment of the above conditions. The additional active ingredients may be coadministered separately with a compound of the invention or included with such an agent in a pharmaceutical composition according to the invention. In an exemplary embodiment, additional active ingredients are those that are known or discovered to be effective in the treatment of conditions, disorders, or diseases mediated by orexin activity, such as another orexin modulator or a compound active against another target associated with the particular condition, disorder, or disease. The combination may serve to increase efficacy (e.g., by including in the combination a compound potentiating the potency or effectiveness of an active agent according to the invention), decrease one or more side effects, or decrease the required dose of the active agent according to the invention.
The compounds of the invention are used, alone or in combination with one or more additional active ingredients, to formulate pharmaceutical compositions of the invention. A pharmaceutical composition of the invention comprises: (a) an effective amount of at least one compound in accordance with the invention; and (b) a pharmaceutically acceptable excipient.
Delivery forms of the pharmaceutical compositions containing one or more dosage units of the active agents may be prepared using suitable pharmaceutical excipients and compounding techniques known or that become available to those skilled in the art. The compositions may be administered in the inventive methods by a suitable route of delivery, e.g., oral, parenteral, rectal, topical, or ocular routes, or by inhalation.
The preparation may be in the form of tablets, capsules, sachets, dragees, powders, granules, lozenges, powders for reconstitution, liquid preparations, or suppositories. Preferably, the compositions are formulated for intravenous infusion, topical administration, or oral administration.
For oral administration, the compounds of the invention can be provided in the form of tablets or capsules, or as a solution, emulsion, or suspension. To prepare the oral compositions, the compounds may be formulated to yield a dosage of, e.g., from about 0.05 to about 100 mg/kg daily, or from about 0.05 to about 35 mg/kg daily, or from about 0.1 to about 10 mg/kg daily. For example, a total daily dosage of about 5 mg to 5 g daily may be accomplished by dosing once, twice, three, or four times per day.
Oral tablets may include a compound according to the invention mixed with pharmaceutically acceptable excipients such as inert diluents, disintegrating agents, binding agents, lubricating agents, sweetening agents, flavoring agents, coloring agents and preservative agents. Suitable inert fillers include sodium and calcium carbonate, sodium and calcium phosphate, lactose, starch, sugar, glucose, methyl cellulose, magnesium stearate, mannitol, sorbitol, and the like. Exemplary liquid oral excipients include ethanol, glycerol, water, and the like. Starch, polyvinyl-pyrrolidone (PVP), sodium starch glycolate, microcrystalline cellulose, and alginic acid are suitable disintegrating agents. Binding agents may include starch and gelatin. The lubricating agent, if present, may be magnesium stearate, stearic acid or talc. If desired, the tablets may be coated with a material such as glyceryl monostearate or glyceryl distearate to delay absorption in the gastrointestinal tract, or may be coated with an enteric coating.
Capsules for oral administration include hard and soft gelatin capsules. To prepare hard gelatin capsules, compounds of the invention may be mixed with a solid, semi-solid, or liquid diluent. Soft gelatin capsules may be prepared by mixing the compound of the invention with water, an oil such as peanut oil or olive oil, liquid paraffin, a mixture of mono and di-glycerides of short chain fatty acids, polyethylene glycol 400, or propylene glycol.
Liquids for oral administration may be in the form of suspensions, solutions, emulsions or syrups or may be lyophilized or presented as a dry product for reconstitution with water or other suitable vehicle before use. Such liquid compositions may optionally contain: pharmaceutically-acceptable excipients such as suspending agents (for example, sorbitol, methyl cellulose, sodium alginate, gelatin, hydroxyethylcellulose, carboxymethylcellulose, aluminum stearate gel and the like); non-aqueous vehicles, e.g., oil (for example, almond oil or fractionated coconut oil), propylene glycol, ethyl alcohol, or water; preservatives (for example, methyl or propyl p-hydroxybenzoate or sorbic acid); wetting agents such as lecithin; and, if desired, flavoring or coloring agents.
The active agents of this invention may also be administered by non-oral routes. For example, the compositions may be formulated for rectal administration as a suppository. For parenteral use, including intravenous, intramuscular, intraperitoneal, or subcutaneous routes, the compounds of the invention may be provided in sterile aqueous solutions or suspensions, buffered to an appropriate pH and isotonicity or in parenterally acceptable oil. Suitable aqueous vehicles include Ringer's solution and isotonic sodium chloride. Such forms will be presented in unit-dose form such as ampules or disposable injection devices, in multi-dose forms such as vials from which the appropriate dose may be withdrawn, or in a solid form or pre-concentrate that can be used to prepare an injectable formulation. Illustrative infusion doses may range from about 1 to 1000 μg/kg/minute of compound, admixed with a pharmaceutical carrier over a period ranging from several minutes to several days.
For topical administration, the compounds may be mixed with a pharmaceutical carrier at a concentration of about 0.1% to about 10% of drug to vehicle. Another mode of administering the compounds of the invention may utilize a patch formulation to affect transdermal delivery.
Compounds of the invention may alternatively be administered in methods of this invention by inhalation, via the nasal or oral routes, e.g., in a spray formulation also containing a suitable carrier.

Chemistry:
In obtaining the compounds described in the examples below and the corresponding analytical data, the following experimental and analytical protocols were followed unless otherwise indicated.
Unless otherwise stated, reaction mixtures were magnetically stirred at room temperature (rt) under a nitrogen atmosphere. Where solutions were “dried,” they were generally dried over a drying agent such as Na2SO4 or MgSO4, filtered and concentrated. Where mixtures, solutions, and extracts were “concentrated”, they were typically concentrated on a rotary evaporator under reduced pressure. Reactions under microwave irradiation conditions were carried out in a Biotage Initiator or CEM Discover instrument.
Melting point determinations were performed in open capillary tubes on a FP62 or MP50 apparatus (Mettler-Toledo). Melting points were measured with a temperature gradient of 10° C./minute. Maximum temperature was 300° C. The melting point was read from a digital display.
Normal-phase flash column chromatography (FCC) was performed on silica gel (SiO2) using prepackaged cartridges, eluting with the indicated solvents.
Where compounds were purified by “Prep HPLC” the method employed was either:
Preparative reverse-phase high performance liquid chromatography (HPLC) was performed on a Gilson HPLC with an Xterra Prep RP18 (5 m, 30×100 mm, or 50×150 mm) column, and a gradient of 10 to 99% acetonitrile/water (20 mM NH4OH) over 12 to 18 min, and a flow rate of 30 mL/min. or
Preparative reverse-phase high performance liquid chromatography (HPLC) was performed on a Agilent 1100 Series HPLC with an XBridge C18 column (5 m, 30×100 mm), mobile phase of 5% ACN in 20 mM NH4OH (hold for 2 min) then ramp 5-99% ACN over 15 min, hold at 99% ACN for 5 min. and a flow rate of 40 mL/min. or

Analytical chromatography data was acquired using an Agilent 1100 HPLC, with an Inertsil ODS-3 3 mm 4.6×50 mm column, purchased from GL Sciences (Part #1010L050W046). Samples were run using a gradient profile of 10-99% acetonitrile (ACN) in water, each containing 0.05% trifluoroacetic acid (TFA) over 1.6 minutes, then holding at 99% acetonitrile for 0.3 minutes. Flow rate was 5 mL/min and column temperature was set to 50° C. (Method A).
Mass spectra (MS) were obtained on an Agilent series 1100 MSD using electrospray ionization (ESI) in positive mode unless otherwise indicated. Calculated (calcd.) mass corresponds to the exact mass.
Nuclear magnetic resonance (NMR) spectra were obtained on Bruker model DRX spectrometers. The format of the 1H NMR data below is: chemical shift in ppm downfield of the tetramethylsilane reference (multiplicity, coupling constant J in Hz, integration).
Chemical names were generated using ChemDraw Ultra 12.0 (CambridgeSoft Corp., Cambridge, Mass.) or ACD/Name Version 10.01 (Advanced Chemistry Development, Toronto, Ontario, Canada).
Where compounds were purified by “SFC Chromatography” the method employed was either:
On preparative APS 1010 system with autoprep otion from Berger instrument, consisted of two varian SD-1 pumps (walnut creek, CA, USA), one of which was extensively modified to pump CO2, a special pump head heat exchanger, ajulabo FT 401 chiller (labortechnik GmbH, Sellback, Germany), a model SCM 2500 phase separator (berger instruments) with selection valve and set of collection vessels in a Bodan robot. A model Knauer 2500 UV detector with high pressure flow cell (berlin, germany). Sample were applied using a six-port injection valve (Valco, Houston, Tex., USA)) with a 5 ml sample loop and a model YP-300 syringue pump (cavro, san Jose, Calif.). or

To the title compound of step A (1.44 g, 5.6 mmol) in DCM (56 mL) was added DIPEA (1.25 mL, 7.3 mmol) and intermediate A-2 (1.43 g, 6.1 mmol). Then T3P (50% solution in DMF, 10 mL, 17 mmol) was added dropwise and the reaction heated at 45° C. for 16 h. After allowing to cool to rt, DCM was added and the mixture washed with H2O then saturated NaHCO3 (aq). The combined aq layers were extracted with DCM. The combined organic layers were dried (Na2SO4). Purification via silica gel chromatography (10-100% EtOAc in hexanes) gave the title compound (2 g, 78%).

Assays
The in vitro affinity of the compounds of the invention for the rat/human orexin 1 and human orexin 2 receptors was determined by competitive radioligand binding using [3H] (1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone)(Langmead et al., 2004) and [3H]EMPA (n-ethyl-2[96-methoxy-pyridin-3-yl)-(toluene-2-sulfonyl)-amino]-N-pyridin-3-ylmethyl acetamide), respectively (Langmead et al., 2004, British Journal of Pharmacology 141:340-346; Malherbe et al., 2004, British Journal of Pharmacology 156:1326-41).
The in vitro functional antagonism of the compounds on the human orexin 1 and orexin 2 receptors was determined using fluorometric imaging plate reader (FLIPR) based calcium assays.
Rat and Human Orexin 1 Receptor Radioligand Binding Studies
Human Embryonic Kidney 293 cells (HEK293) stably expressing rat orexin 1 receptor (Genebank accession number NM_001525) or Chinese ovary cells (CHO) stably expressing human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat # SH30022), 10% FBS, 1× Pen/Strep, 1× sodium pyruvate, 10 mM HEPES, 600 μg/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10% FBS, 1× Pen/Strep, 600 μg/mL G418 media, respectively on 150 cm2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1× with Calcium and Magnesium, Cat # SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2K×G, 5 min at 4° C.), the supernatant was aspirated and the pellets frozen and stored at −800 C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-SB674042 (Moraveck Corporation, specific activity=35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentrations (from 0.1 nM to 10 μM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 μM almorexant. The total volume of each reaction is 200 μL (20 μL of diluted compounds, 80 μL of [3H]-(1-(5-(2-fluoro-phenyl)-2-methyl-thiazol-4-yl)-1-((S)-2-(5-phenyl-(1,3,4)oxadiazol-2-ylmethyl)-pyrrolidin-1-yl)-methanone) diluted in PBS and 100 μL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).
IC50 values (i.e. concentration of unlabelled compound required to compete for 50% of specific binding to the radioligand) was calculated using the GraphPad Prism software (GraphPad Prism Software Inc., San Diego, Calif.) with a fit to a sigmoidal dose-response curve. Apparent Ki values were calculated as Ki=IC50/(1+C/Kd), where C is concentration of radioligand and Kd=4 nM for rat orexin 1 receptor and 6 nM for human orexin 1 receptor.
Human Orexin 2 Receptor Radioligand Binding Studies
HEK293 stably expressing human orexin 2 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM (Hyclone, cat # SH30022), 10% FBS, 1× Pen/Strep, 1× NaPyruvate, 10 mM HEPES, 600 g/ml G418 media on 150 cm2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco's Phosphate Buffered Saline 1× with Calcium and Magnesium, Cat # SH30264.01, hereafter referred to simply as PBS) and scraped into 50 ml tubes. After centrifugation (2K xG, 5 min at 40° C.), the supernatant was aspirated and the pellets frozen and stored at −800° C. Cells were resuspended in PBS in the presence of 1 tablet of protease inhibitor cocktail (Roche, Cat. #11836145001) per 50 mL. Each cell pellet from a 15 cm plate was resuspended in 10 mL, stored on ice, and homogenized for 45 sec just prior to addition to the reactions. Competition binding experiments in 96 well polypropylene plates were performed using [3H]-EMPA (Moraveck Corporation, specific activity=29.6 Ci/mmol), diluted to a 5 nM concentration in PBS (2 nM final concentration). Compounds were solubilized in 100% DMSO (Acros Organics, Cat. #61042-1000) and tested over a range of 7 concentration (from 0.1 nM to 10 μM). The final concentration of DMSO in the reactions is equal to or less than 0.1%. Total and nonspecific binding was determined in the absence and presence of 10 μM almorexant. The total volume of each reaction is 200 μL (20 μL of diluted compounds, 80 μL of [3H]-EMPA diluted in PBS and 100 μL of the cell suspension). Reactions were run for 60 min at room temperature and terminated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell harvester (PerkinElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55° C. oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).
IC50 values (i.e. concentration of unlabelled compound required to compete for 50% of specific binding to the radioligand) was calculated using the GraphPad Prism software (GraphPad Prism Software Inc., San Diego, Calif.) with a fit to a sigmoidal dose-response curve. Apparent Ki values were calculated as Ki=IC50/(1+C/Kd), where C is concentration of radioligand and Kd=2 nM.
Human Orexin 1 Receptor Ca2+ Mobilization Assay
CHO cells stably transfected with the human orexin 1 receptor (Genebank accession number NM_001526) were grown to confluency in DMEM/F12, 10% FBS, 1× pen-strep, 400 g/ml G418. Cells were seeded on to 384-well Packard viewplates at a density of 10,000 cells/well and incubated overnight at 370 C, 5% CO2. The cells were dye-loaded with BD Calcium Assay kit (BD, cat #640178) in HBSS (Gibco, cat#14025-092) with 2.5 mM probenecid and incubated at 37° C., 5% CO2 for 45 min. Cells were pre-incubated with compounds (diluted in DMEM/F-12) for 15-30 minutes before agonist (orexin A, 10 nM) stimulation. Ligand-induced Ca2+ release was measured using a Fluorometric Imaging Plate Reader (FLIPR, Molecular Devices, Sunnyvale, Calif.). Functional responses were measured as peak fluorescence intensity minus basal. The concentration of agonist that produced a half-maximal response is represented by the EC50 value. Antagonistic potency values were converted to apparent pKB values using a modified Cheng-Prusoff correction. Apparent pKB=−log IC50/1+[conc agonist/EC50]. Data are expressed as mean±S.E.M.
Human Orexin 2 Receptor Ca2+ Mobilization Assay
PFSK-1 cells endogenously expressing the human orexin 2 receptor were grown to confluency in RPMI1640 (Hyclone, cat#30027.02), 10% FBS, 1× pen-strep. Cells were seeded on to 384-well Packard viewplates at a density of 5,000 cells/well and incubated overnight at 370 C, 5% CO2. The cells were dye-loaded with BD Calcium Assay kit (BD, cat #640178) in HBSS (Gibco, cat#14025-092) with 2.5 mM probenecid and incubated at 37° C., 5% CO2 for 45 min. Cells were pre-incubated with compounds (diluted in DMEM/F-12) for 15-30 minutes before agonist (orexin B, 100 nM) stimulation. Ligand-induced Ca2+ release was measured using a Fluorometric Imaging Plate Reader (FLIPR, Molecular Devices, Sunnyvale, Calif.). Functional responses were measured as peak fluorescence intensity minus basal. The concentration of agonist that produced a half-maximal response is represented by the EC50 value. Antagonistic potency values were converted to apparent pKB values using a modified Cheng-Prusoff correction. Apparent pKB=−log IC50/1+[conc agonist/EC50]. Data are expressed as mean±S.E.M.
