NZ 793902 PRD3282WOPCT SUBSTITUTED 2-AZABICYCLES AND THEIR USE AS OREXIN RECEPTOR MODULATORS CROSS REFERENCE TO RELATED APPLICATIONS This application is a patent of on of New Zealand patent application 710872, which is the national phase entry in New Zealand of PCT international application (published as WO 65070), and claims the benefit of U.S. Provisional ation No. 61/780,378, filed March 13, 2013, which is incorporated herein by reference in its entirety.
TECHNICAL FIELD The present ion is directed to substituted 2-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.
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 l nervous , neurons producing pre-pro orexin are found solely in the perifornical s, 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 -1 and orexin-2 receptors. Orexin-1 and -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 cological differences. Orexin-A and -B are usually ered 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 ai et al., 1998, Cell 92: 573-585; Ammoun et al., 2003, J. Pharmacol. Exp. Ther. 305: 507-514).
PRD3282WOPCT Many s of the brain have fairly selective sion of the orexin-1 or orexin-2 receptors s et al., 2001, J. 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 s like the dorsal raphe, the ventral tegmental area or the prefontal cortex both receptors are coexpressed.
The broad CNS distribution of cells ing orexin, as well as cells sing the orexin receptors, suggests involvement of orexin in a number of physiological functions, ing g and metabolism, regulation of wakefulness and sleep, sympathetic activation and stress response (de Lecea, 2012, Progress in Brain ch, 198, 15-24; Kukkonen, 2013, Am J. l. Cell Physiol., 304, ). Orexin also plays a key role regulating motivation and reward associated with food intake and with drugs of abuse r 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, m. Biophys. Res. Comm. 290: 1237-1245). Rodents whose o 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 -2 receptor modulator activity. Examples of sleep-wake disorders that may be d 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 PRD3282WOPCT modulators that down-regulate orexin-2 receptor-mediated processes e insomnia, ss leg syndrome, jet lag (wakefulness) and sleep disorders secondary to neurological disorders such as mania, schizophrenia, pain mes 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 ch, 198, 79-121). Orexinergic neurons send tions 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 nist 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 stressinduced reinstatement of ethanol (Lawrence et al., 2006, Br J Pharmacol, 148, 9), in addition to attenuating precipitated morphine withdrawal (Sharf et al., 2008, Biol Psychiatry, 64, 175-183) and nicotine dministration (Hollander et al., 2008, Proc Natl Acad Sci U S A., 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 ng (Johnson et al., 2012, ss 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 eptic patients (Johnson et al., 2010, Nature Medicine, 16, 111-115; Fortuyn et al., 2010, l Hospital Psychiatry, 32, 49–56; Strawn et al., 2010, neuroendocrinology, 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 or 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, an Neuropsychopharmacology, 17, 573-579; n et al., 2003, Biol Psychiatry,54, 96-104). A PRD3282WOPCT 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- The orexin system also interacts with brain dopamine systems. erebroventricular ions of orexin in mice se 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 downregulators to treat Parkinson’s disease, Tourette’s syndrome, anxiety, delerium 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 gessner & Liu, 1999, Neuron 24: 941-951) and to stimulate gastric acid secretion in vitro ashi et al., 1999, m. 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 ne prevent the effect of an erebroventricular 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 lism and appetite may be mediated in the gut, where, as mentioned, s alter gastric motility and gastric acid ion. Orexin antagonists therefore are likely to be useful in treatment of ight or obesity and conditions related to overweight or y, 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 nsion, ardia, ammenorrhea and related infertility, and eating disorders such as anorexia and bulimia.
Intracerebroventricularly administered s 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 PRD3282WOPCT agonists may therefore be candidates for treatment of hypotension, ardia and heart failure related thereto, while orexin receptor antagonists may be useful for ent of hypertension, tachycardia and other arrhythmias, angina pectoris and acute heart e.
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 or systems.

"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 s.
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 or 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 ent of such atoms may be determined within the skill of the art. Likewise, also described is the preparation of isotopic ts with sotopes, in the instance for example, where the resulting compounds may be used for drug and/or substrate tissue distribution s. Radiolabeled compounds described herein can be used in diagnostic methods such as Single-photon on computed aphy (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 ncy.
All isotopic variants of the compounds described herein, radioactive or not, are ed to be encompassed within the scope of the present disclosure. In one aspect, bed herein are deuterated analogs of compounds of Formula I as described in the es section. In one embodiment, ated analogs of compounds of Formula I comprise deuterium atoms attached to one or more positions on the 2-azabicyclic ring, such as bridgehead s, or non-bridgehead carbons of the 2-azabicyclic ring, and preferably comprise one or more deuterium atoms attached to 2WOPCT non-bridgehead carbons of the 2-azabicyclic ring. Also contemplated within the scope of embodiments described herein are compounds in which a single proton in compounds of Formula I is replaced with a deuterium, or 2 protons in nds of Formula I are replaced with deuterium, or more than 2 protons in compounds of Formula I are replaced with deuterium. Deuteration of a compound of Formula I may also be effected on one or more substituents (such as e.g., ring A, R1, R2, or R5) present on the 2-azabicyclic ring.
It is also to be understood that nds 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 rs." Isomers that differ in the ement 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 omer 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 rotatory or levorotatory (i.e., as (+) or (-)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A e containing equal proportions of the enantiomers is called a "racemic e." "Tautomers" refer to compounds that are interchangeable forms of a particular compound structure, and that vary in the cement of en atoms and electrons. Thus, two structures may be in equilibrium through the movement of π electrons and an atom (usually H). For e, 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 nd of interest.
Compounds described herein 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.
PRD3282WOPCT The compounds described herein may possess one or more asymmetric centers; such compounds can therefore be produced as individual (R)-or (S)-stereoisomers or as mixtures thereof.
Unless indicated otherwise, the description or naming of a particular compound in the specification and claims is intended to include both individual enantiomers and mixtures, racemic or otherwise, thereof. The methods for the determination of stereochemistry and the separation of stereoisomers are well-known in the art.

Assays: The in vitro ty 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- -phenyl)methyl-thiazolyl)((S)(5-phenyl-(1,3,4)oxadiazolylmethyl)-pyrrolidin- 1-yl)-methanone)(Langmead et al., 2004) and [3H]EMPA (n-ethyl-2[96-methoxy-pyridinyl)- (toluenesulfonyl)-amino]-N-pyridinylmethyl acetamide), respectively (Langmead et al., 2004, British Journal of Pharmacology 141:340-346; Malherbe et al., 2004, British Journal of Pharmacology 26-41).
The in vitro functional antagonism of the compounds on the human orexin 1 and orexin 2 receptors was determined using fluorometric imaging plate reader ) based calcium assays.
Data are analyzed using pc-Sandy macro and graphed on Graphpad Prism 5. For analysis, each concentration point is averaged from triplicate values and the ed values are plotted on Graphpad Prism. The IC50 was determined by applying the following equation (GraphPad Prism .0, SanDiego) for one site competition where X=log (concentration) and Y=specific binding. Top denotes the total [3H]- (1-(5-(2-fluoro-phenyl)methyl-thiazolyl)((S)(5-phenyl- (1,3,4)oxadiazolylmethyl)-pyrrolidinyl)-methanone) binding, bottom denotes the nonspecific [3H]- (1-(5-(2-fluoro-phenyl)methyl-thiazolyl)((S)(5-phenyl-(1,3,4)oxadiazol ylmethyl)-pyrrolidinyl)-methanone) g. Graphpad Prism calculates Ki value from IC50 and the pre-determined Kd values for [3H]- (1-(5-(2-fluoro-phenyl)methyl-thiazolyl)((S)(5- phenyl-(1,3,4)oxadiazolylmethyl)-pyrrolidinyl)-methanone) and [3H]-EMPA. The Ki for each compound is then uploaded into 3DX. Each run ses individual compounds in triplicate. The data in Table 1 and Table 2 represent averages from between 2-20 runs PRD3282WOPCT 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 e 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, 1X rep, 1X sodium pyruvate, 10 mM HEPES, 600 µg/mL G418 and DMEM/F12 (Gibco, Cat #11039), 10%FBS, 1X Pen/Strep, 600 µg/mL G418 media, respectively on 150 cm2 tissue e plates, washed with 5 mM EDTA in PBS (HyClone Dulbecco’s Phoshpate Buffered Saline 1X 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 4 °C), the supernatant was aspirated and the pellets frozen and stored at –800C. 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]- (1-(5-(2-fluoro-phenyl) methyl-thiazolyl)((S)(5-phenyl-(1,3,4)oxadiazolylmethyl)-pyrrolidinyl)-methanone) (Moraveck Corporation, specific activity = 35.3 Ci/mmol), diluted to a 10 nM concentration in PBS (4 nM final). Compounds were lized 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)methyl-thiazolyl)((S) (5-phenyl-(1,3,4)oxadiazolylmethyl)-pyrrolidinyl)-methanone) diluted in PBS and 100 µL of the cell suspension). Reactions were run for 60 min at room temperature and ated by filtration through GF/C filter plates (PerkinElmer, Cat. #6005174) presoaked in 0.3% polyethylenimine using the cell ter nElmer Filtermate). The plates were washed 3 times by aspirating 30 ml PBS through the plates. Plates were dried in 55 oC oven for 60 min, scintillation fluid was added, and the ctivity was d on a Topcount (Packard).
IC50 values (i.e. concentration of unlabelled compound required to e for 50% of specific binding to the radioligand) was calculated using the GraphPad Prism software (GraphPad Prism Software Inc., San Diego, CA) with a fit to a sigmoidal esponse curve. Apparent Ki PRD3282WOPCT 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 or.
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, 1X Pen/Strep, 1X NaPyruvate, 10 mM HEPES, 600 ug/ml G418 media on 150 cm2 tissue culture plates, washed with 5 mM EDTA in PBS (HyClone co’s Phoshpate ed Saline 1X 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 40C), the atant was aspirated and the pellets frozen and stored at –800C.

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 g experiments in 96 well polypropylene plates were performed using [3H]-EMPA (Moraveck Corporation, specific ty = 29.6 Ci/mmol), diluted to a 5 nM concentration in PBS (2 nM final concentration). nds were solubilized in 100% DMSO (Acros Organics, Cat. -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 g was ined 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 55oC oven for 60 min, scintillation fluid was added, and the radioactivity was counted on a Topcount (Packard).
