Description
BRIEF DESCRIPTION OF FIGURES

DETAILED DESCRIPTION OF THE EMBODIMENTS
(3) The present invention is based on the discovery of compounds of Formula I and their use in treating a range of mental, neurological, and behavioural disorders. In particular, the compounds of Formula I have been found to act as selective agonists for the oxytocin receptor (OXTR).
(4) Compounds exhibiting a head group that is structurally similar to compounds of Formula I are known, for example the WAY 267464 compound (see image below) is a nonpeptide agonist for the oxytocin receptor.
(5) ##STR00009##
(6) Furthermore, patent publications WO 2006/021213 and WO 03/000692 disclose vasopressin VIA antagonists and an oxytocin agonist respectively which exhibit similar architecture to the WAY 267,464 compound in that a number of the compounds disclosed therein include pyrazolo[1,4] diazepine head groups with long pendant chains extending from the nitrogen atom in the 4 position of the diazepine ring. However, these large compounds exhibit a number of draw backs in comparison with compounds of Formula I. For example, while these compounds can act as an OXTR agonist, these compounds also bind with the vasopressin V1a receptor (V1aR), generally as an antagonist. Other issues include poor bioavailability of these compounds, due to difficulties with these compounds crossing the blood brain barrier, or the metabolism of these compounds into smaller fragments which then have no effect or a deleterious effect.
(7) Frantz et al. conducted a study in 2010 to systematically evaluate the structural determinants of the affinity and efficacy of representative ligands of the V1a, V2, and OT receptor subtypes (see Frantz et al. “Subtlety of the Structure—Affinity and Structure—Efficacy Relationships around a Nonpeptide Oxytocin Receptor Agonist”, J. Med. Chem., 2010, 53, 1546-1562).
(8) One of the compounds assessed by Frantz et al. was the compound below:
(9) ##STR00010##
(10) Frantz et al. divided this compound into a “western part” which covered only the pyrazolo[1,4] diazepine head group, and an “eastern part” which covered the tail group extending from the nitrogen atom in the 4 position of the diazepine ring. Frantz et al. then studied the effects of varying the head group of the “western part” and truncating the “eastern part” of the compound. Interestingly, Frantz et al. demonstrated that truncation of the “eastern part” of the overall molecule resulted in the molecule acting as an antagonist for the OXTR, or in some cases being inactive in respect of OXTR. Based on this, Frantz et al. concluded that a long tail including at least the urea linkage is necessary for the OXTR activation.
(11) Surprisingly, the inventors have found that compounds of Formula I not only act as OXTR agonists, but in many instances are highly selective for the OXTR, having minimal or no affinity for V1aR. The compounds of Formula I, being comparatively small molecules, are also less susceptible to issues of bioavailability and metabolic breakdown that plague some of these larger molecules.
(12) The compounds of Formula I act at the OXTR while avoiding a number of pitfalls associated with the native ligand (i.e. oxytocin) or the compounds discussed in WO 2006/021213, WO 03/000692, and Frantz et al. As such, the compounds avoid or reduce the problems mentioned above for OT and have widespread and valuable applications for a range of conditions or disorders that may be treated by an OXTR agonist. In addition to treating disease states, selective small molecules allow for molecular probes for the OT receptor.
(13) In view of the above, the invention also relates to a pharmaceutical composition including the compound of Formula I. The compound of Formula I is included in a pharmaceutically effective amount, sufficient to produce a desired effect upon a process or condition of a disease.
(14) An appropriate dosage level will generally be about 0.01 to 500 mg per kg patient body weight per day which can be administered in single or multiple doses. Preferably, the dosage level will be about 0.1 to about 250 mg/kg per day; more preferably about 0.5 to about 100 mg/kg per day. A suitable dosage level may be about 0.01 to 250 mg/kg per day, about 0.05 to 100 mg/kg per day, or about 0.1 to 50 mg/kg per day. Within this range the dosage may be 0.05 to 0.5, 0.5 to 5 or 5 to 50 mg/kg per day. For oral administration, the compositions are preferably provided in the form of tablets containing 1.0 to 1000 milligrams of the active ingredient, particularly 1.0, 5.0, 10.0, 15.0, 20.0, 25.0, 50.0, 75.0, 100.0, 150.0, 200.0, 250.0, 300.0, 400.0, 500.0, 600.0, 750.0, 800.0, 900.0, and 1000.0 milligrams of the active ingredient for the symptomatic adjustment of the dosage to the patient to be treated. The compounds may be administered on a regimen of 1 to 4 times per day, preferably once or twice per day. It will be understood, however, that the specific dose level and frequency of dosage for any particular patient may be varied and will depend upon a variety of factors including the activity of the specific compound employed, the metabolic stability and length of action of that compound, the age, body weight, general health, sex, diet, mode and time of administration, rate of excretion, drug combination, the severity of the particular condition, and the host undergoing therapy. The amount of a compound of the present invention in the composition will also depend upon the particular compound in the composition.
(15) The pharmaceutical composition may further comprise other therapeutically active compounds which are usually applied in the treatment of the disclosed disorders or conditions. Selection of the appropriate agents for use in combination therapy may be made by one of ordinary skill in the art, according to conventional pharmaceutical principles. The combination of therapeutic agents may act synergistically to effect the treatment or prevention of the various disorders or conditions disclosed herein. Using this approach, one may be able to achieve therapeutic efficacy with lower dosages of each agent, thus reducing the potential for adverse side effects.
(16) Compounds and compositions of the invention may be formulated for any appropriate route of administration including, for example, topical (for example, transdermal or ocular), oral, buccal, nasal, vaginal, rectal or parenteral administration. The term parenteral as used herein includes subcutaneous, intradermal, intravascular (for example, intravenous), intramuscular, spinal, intracranial, intrathecal, intraocular, periocular, intraorbital, intrasynovial and intraperitoneal injection, as well as any similar injection or infusion technique. In certain embodiments, compositions in a form suitable for oral use or parenteral use are preferred. Suitable oral forms include, for example, tablets, troches, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixirs. Within yet other embodiments, compositions provided herein may be formulated as a lyophilizate.
(17) The various dosage units are each preferably provided as a discrete dosage tablet, capsules, lozenge, dragee, gum, or other type of solid formulation. Capsules may encapsulate a powder, liquid, or gel. The solid formulation may be swallowed, or may be of a suckable or chewable type (either frangible or gum-like). The present invention contemplates dosage unit retaining devices other than blister packs; for example, packages such as bottles, tubes, canisters, packets. The dosage units may further include conventional excipients well-known in pharmaceutical formulation practice, such as binding agents, gellants, fillers, tableting lubricants, disintegrants, surfactants, and colorants; and for suckable or chewable formulations.
(18) Compositions intended for oral use may further comprise one or more components such as sweetening agents, flavouring agents, colouring agents and/or preserving agents in order to provide appealing and palatable preparations. Tablets contain the active ingredient in admixture with physiologically acceptable excipients that are suitable for the manufacture of tablets. Such excipients include, for example, inert diluents such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate, granulating and disintegrating agents such as corn starch or alginic acid, binding agents such as starch, gelatine or acacia, and lubricating agents such as magnesium stearate, stearic acid or talc. The tablets may be uncoated or they may be coated by known techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monosterate or glyceryl distearate may be employed.
(19) Formulations for oral use may also be presented as hard gelatine capsules wherein the active ingredient is mixed with an inert solid diluent such as calcium carbonate, calcium phosphate or kaolin, or as soft gelatine capsules wherein the active ingredient is mixed with water or an oil medium such as peanut oil, liquid paraffin or olive oil.
(20) Aqueous suspensions contain the active ingredient(s) in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients include suspending agents such as sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia, and dispersing or wetting agents such as naturally-occurring phosphatides (for example, lecithin), condensation products of an alkylene oxide with fatty acids such as polyoxyethylene stearate, condensation products of ethylene oxide with long chain aliphatic alcohols such as heptadecaethyleneoxycetanol, condensation products of ethylene oxide with partial esters derived from fatty acids and a hexitol such as polyoxyethylene sorbitol mono-oleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides such as polyethylene sorbitan monooleate. Aqueous suspensions may also comprise one or more preservatives, for example ethyl, or n-propyl p-hydroxybenzoate, one or more colouring agents, one or more flavouring agents, and one or more sweetening agents, such as sucrose or saccharin.

The oily suspensions may contain a thickening agent such as beeswax, hard paraffin or cetyl alcohol. Sweetening agents such as those set forth above, and/or flavouring agents may be added to provide palatable oral preparations. Such suspensions may be preserved by the addition of an antioxidant such as ascorbic acid.
(22) Dispersible powders and granules suitable for preparation of an aqueous suspension by the addition of water provide the active ingredient in admixture with a dispersing or wetting agent, suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients, such as sweetening, flavouring and colouring agents, may also be present.
(23) Pharmaceutical compositions may also be in the form of oil-in-water emulsions. The oily phase may be a vegetable oil such as olive oil or arachis oil, a mineral oil such as liquid paraffin, or a mixture thereof. Suitable emulsifying agents include naturally-occurring gums such as gum acacia or gum tragacanth, naturally-occurring phosphatides such as soy bean lecithin, and esters or partial esters derived from fatty acids and hexitol, anhydrides such as sorbitan monoleate, and condensation products of partial esters derived from fatty acids and hexitol with ethylene oxide such as polyoxyethylene sorbitan monoleate. An emulsion may also comprise one or more sweetening and/or flavouring agents.
(24) Syrups and elixirs may be formulated with sweetening agents, such as glycerol, propylene glycol, sorbitol or sucrose. Such formulations may also comprise one or more demulcents, preservatives, flavouring agents and/or colouring agents.
(25) Compositions of the invention may be formulated for local or topical administration, such as for topical application to the skin. Formulations for topical administration typically comprise a topical vehicle combined with active agent(s), with or without additional optional components.
(26) Suitable topical vehicles and additional components are well known in the art, and it will be apparent that the choice of a vehicle will depend on the particular physical form and mode of delivery. Topical vehicles include organic solvents such as alcohols (for example, ethanol, iso-propyl alcohol or glycerine), glycols such as butylene, isoprene or propylene glycol, aliphatic alcohols such as lanolin, mixtures of water and organic solvents and mixtures of organic solvents such as alcohol and glycerine, lipid-based materials such as fatty acids, acylglycerols including oils such as mineral oil, and fats of natural or synthetic origin, phosphoglycerides, sphingolipids and waxes, protein-based materials such as collagen and gelatine, silicone-based materials (both nonvolatile and volatile), and hydrocarbon-based materials such as microsponges and polymer matrices.
(27) A composition may further include one or more components adapted to improve the stability or effectiveness of the applied formulation, such as stabilizing agents, suspending agents, emulsifying agents, viscosity adjusters, gelling agents, preservatives, antioxidants, skin penetration enhancers, moisturizers and sustained release materials. Examples of such components are described in Martindale—The Extra Pharmacopoeia (Pharmaceutical Press, London 1993) and Martin (ed.), Remington's Pharmaceutical Sciences. Formulations may comprise microcapsules, such as hydroxymethylcellulose or gelatine-microcapsules, liposomes, albumin microspheres, microemulsions, nanoparticles or nanocapsules.
(28) A topical formulation may be prepared in a variety of physical forms including, for example, solids, pastes, creams, foams, lotions, gels, powders, aqueous liquids, emulsions, sprays and skin patches. The physical appearance and viscosity of such forms can be governed by the presence and amount of emulsifier(s) and viscosity adjuster(s) present in the formulation. Solids are generally firm and non-pourable and commonly are formulated as bars or sticks, or in particulate form. Solids can be opaque or transparent, and optionally can contain solvents, emulsifiers, moisturizers, emollients, fragrances, dyes/colorants, preservatives and other active ingredients that increase or enhance the efficacy of the final product. Creams and lotions are often similar to one another, differing mainly in their viscosity. Both lotions and creams may be opaque, translucent or clear and often contain emulsifiers, solvents, and viscosity adjusting agents, as well as moisturizers, emollients, fragrances, dyes/colorants, preservatives and other active ingredients that increase or enhance the efficacy of the final product. Gels can be prepared with a range of viscosities, from thick or high viscosity to thin or low viscosity. These formulations, like those of lotions and creams, may also contain solvents, emulsifiers, moisturizers, emollients, fragrances, dyes/colorants, preservatives and other active ingredients that increase or enhance the efficacy of the final product. Liquids are thinner than creams, lotions, or gels, and often do not contain emulsifiers. Liquid topical products often contain solvents, emulsifiers, moisturizers, emollients, fragrances, dyes/colorants, preservatives and other active ingredients that increase or enhance the efficacy of the final product.
(29) Emulsifiers for use in topical formulations include, but are not limited to, ionic emulsifiers, cetearyl alcohol, non-ionic emulsifiers like polyoxyethylene oleyl ether, PEG-40 stearate, ceteareth-12, ceteareth-20, ceteareth-30, ceteareth alcohol, PEG-100 stearate and glyceryl stearate. Suitable viscosity adjusting agents include, but are not limited to, protective colloids or nonionic gums such as hydroxyethylcellulose, xanthan gum, magnesium aluminum silicate, silica, microcrystalline wax, beeswax, paraffin, and cetyl palmitate. A gel composition may be formed by the addition of a gelling agent such as chitosan, methyl cellulose, ethyl cellulose, polyvinyl alcohol, polyquaterniums, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, carbomer or ammoniated glycyrrhizinate. Suitable surfactants include, but are not limited to, nonionic, amphoteric, ionic and anionic surfactants. For example, one or more of dimethicone copolyol, polysorbate 20, polysorbate 40, polysorbate 60, polysorbate 80, lauramide DEA, cocamide DEA, and cocamide MEA, oleyl betaine, cocamidopropyl phosphatidyl PG-diimonium chloride, and ammonium laureth sulfate may be used within topical formulations.
(30) Preservatives include, but are not limited to, antimicrobials such as methylparaben, propylparaben, sorbic acid, benzoic acid, and formaldehyde, as well as physical stabilizers and antioxidants such as vitamin E, sodium ascorbate/ascorbic acid and propyl gallate. Suitable moisturizers include, but are not limited to, lactic acid and other hydroxy acids and their salts, glycerine, propylene glycol, and butylene glycol. Suitable emollients include lanolin alcohol, lanolin, lanolin derivatives, cholesterol, petrolatum, isostearyl neopentanoate and mineral oils. Suitable fragrances and colours include, but are not limited to, FD&C Red No. 40 and FD&C Yellow No. 5. Other suitable additional ingredients that may be included in a topical formulation include, but are not limited to, abrasives, absorbents, anticaking agents, antifoaming agents, antistatic agents, astringents (such as witch hazel), alcohol and herbal extracts such as chamomile extract, binders/excipients, buffering agents, chelating agents, film forming agents, conditioning agents, propellants, opacifying agents, pH adjusters and protectants.
(31) Typical modes of delivery for topical compositions include application using the fingers, application using a physical applicator such as a cloth, tissue, swab, stick or brush, spraying including mist, aerosol or foam spraying, dropper application, sprinkling, soaking, and rinsing. Controlled release vehicles can also be used, and compositions may be formulated for transdermal administration (for example, as a transdermal patch).
(32) Pharmaceutical compositions may be formulated as sustained release formulations such as a capsule that creates a slow release of modulator following administration. Such formulations may generally be prepared using well-known technology and administered by, for example, oral, rectal or subcutaneous implantation, or by implantation at the desired target site. Carriers for use within such formulations are biocompatible, and may also be biodegradable. Preferably, the formulation provides a relatively constant level of modulator release. The amount of modulator contained within a sustained release formulation depends upon, for example, the site of implantation, the rate and expected duration of release and the nature of the disorder to be treated or prevented.
(33) In another form, the invention relates to a method of treating a subject, the method including administering a pharmaceutically effective amount of a compound of Formula I, in a pharmaceutically acceptable form, to the subject.

(257) Examples Testing the Selectivity of Compounds of Formula I
(258) The following example demonstrates the selectivity of some of the compounds of Formula I for the OXTR over V1aR.
(259) Generation of OTR and V.sub.1aR-Expressing Human Embryonic Kidney (HEK) Cells
(260) Human embryonic kidney cells (HEK-293) transfected to stably express untagged hOTR and V.sub.1aR using the Flp-In™ T-REx™ system (Life Technologies, Carlsbad, Calif. USA) were established as reported in Jorgensen et al., 2016 (the entire disclosure of which is hereby incorporated by reference). Cells were subsequently maintained in 10% DMEM containing hygromycin (80 μg/ml), penicillin (100 U/ml), streptomycin (0.1 mg/ml) and blasticidine S hydrochloride (15 μg/ml).
(261) Membrane Preparation
(262) To induce receptor expression, cells were incubated with tetracycline (2 μg/mL) for 48 h. PBS with 5 mM EDTA (pH 7.4) was used to detach OTR and V.sub.1aR-expressing HEK293 cells from culture flasks. Harvested cells were centrifuged at 1200 g for 5 min and were resuspended in homogenization buffer (50 mM HEPES, 5 mM EDTA, 5 mM MgCl.sub.2; pH 7.4) prior to homogenization using an Ultra-Turrax homogeniser (IKA, Wilmington, N.C., USA). Homogenates were centrifuged three times for 30 min at 48.000 g, 4° C. for 30 min and membrane pellets resuspended in 50 mM Tris HCl, 5 mM MgCl.sub.2 (pH 7.4). A bicinchoninic acid assay was used according to the manufacturer's protocol (Bio-Rad, Hercules. Calif., USA) to measure final protein concentration. Membranes were stored at −80° C. until use in competition radioligand binding studies.
(263) Competition Radioligand Binding
(264) Membranes (50□□g/well) were incubated with [Tyrosyl-2,6-.sup.3H]-oxytocin (10 nM) or [Phenylalanyl-3,4,5-.sup.3H]-vasopressin (8-L-arginine) (2 nM; Perkin Elmer, Waltham, Miss., USA) and logarithmically-spaced concentrations of competing compounds (1 nM-10 □M) in reaction buffer (50 mM Tris HCl, 5 mM MgCl.sub.2, pH 7.4). Reactions were incubated for 90 min at 4° C. to reach equilibrium, and terminated by rapid filtration over glass fibre filters (Whatman GF/A 1.6 μM; Millipore, Darmstadt, Germany), and washing with ice-cold reaction buffer. Filters were dried, then incubated with Microscint 0 (Perkin Elmer) for 30 min before radioactivity was detected with a Microbeta2 2450 microplate-reader (Perkin Elmer). Nonspecific binding was determined in the presence of 1 □M cold oxytocin or vasopressin (Sigma Aldrich), and was subtracted from total binding values to calculate specific binding values. Specific binding in the presence of compounds was expressed as a percentage of specific binding in the presence of vehicle control. A sum-of-squares F-test was used to compare the goodness of fit of one-site, two-site and sigmoidal with variable hill slope binding models, and to calculate K.sub.i's using Graphpad Prism (Graphpad Software, La Jolla, Calif., USA).
(265) IP1 Accumulation Assays
(266) OTR or V.sub.1aR-expressing HEK-293 cells were seeded onto poly-L-lysine (100 μg/ml)-coated 384-well plates at a density of 8.75×10.sup.3 cells per well. Cells were incubated in tetracycline (2 μg/mL) for 48 h to induce receptor expression. Intracellular IP1 levels induced by activation of the G.sub.q protein coupled to the OTR and V1aR was indexed using the HTRF IP-One kit (CisBio International, Bedford, Mass., USA), according to manufacturer's protocol. For agonist assessment, cells were incubated with logarithmically-spaced concentrations of compounds (1 nM-100 μM) for 1 h prior to the addition of Ab-Cryptate and IP1-d2 for 1 h. The contents of each well were transferred to a white-walled proxy plate (Perkin Elmer) and fluorescence read using a Pherastar Microplate reader (BMG Labtech, Cary, N.C., USA). For antagonist assessment, cells were incubated an ˜EC.sub.70 concentration of OT (30 nM) or AVP (25 nM) mixed with compounds (1 nM-100 μM) or vehicle control for 1 h. IP1 levels in the presence of compounds and OT or AVP were expressed as a percentage of levels seen with OT or AVP in the presence of vehicle control. Concentration response curves for OT and AVP were determined after 5 min incubation in drug or vehicle, and the data fitted using GraphPad PRISM to a 4-parameter logistic equation of the form y=Min+(Max−Min)/(1+10{circumflex over ( )}((logEC.sub.50−X)*n)) where X is drug concentration and n is the H-ill slope. Data represent the mean±s.d. of at least 3 independent experiments, each in duplicate.

(270) Species: Mus musculus
(271) Strain: BALB/c
(272) Sex: Male
(273) Age: 6-7 weeks at testing
(274) Vehicle: 88% isotonic saline, 10% DMSO, 2% tween 80
(275) Compound: WJ0629
(276) Doses: 0, 1, 5, 20 mg/kg
(277) Route of administration: intraperitoneal (i.p.) injection
(278) Mice were placed in the arena (40×40×40 cm) in weight and treatment matched pairs of unfamiliar mice for a 10 min test session, commencing 30 min after receiving their i.p. injection. The variables of interest were the time the mice spent in close physical contact with each other and the time each mouse spent engaged in active social investigation (sniffing the other mouse).
