Description
TRIAZOLOBENZAZEPÏNES AS VASOPRESSIN V1A RECEPTOR ANTAGONISTS
THE FIELD OF THE INVENTION
The présent invention relates to 5,6-dihydro-4H-[1,2,4]triazolo[4,3-a][1]benzazepine dérivatives of general formula (I) and/or salts thereof and/or géométrie isomers thereof and/or stereoisomers thereof and/or enantiomers thereof and/or racemates thereof and/or diastereomers thereof and/or biologically active métabolites thereof and/or prodrugs thereof and/or solvatés thereof and/or hydrates thereof and/or polymorphs thereof which are centrally and/or peripherally acting V1a receptor modulators, particularly V1a receptor antagonists. Additional subject of the présent invention is the process for the préparation of the compounds and intermediates of the préparation process as well. The invention also relates to pharmaceutical compositions containing the compounds and to the use thereof in the treatment and/or prophylaxis of a disease or condition associated with V1a receptor function.
THE BACKGROUND OF THE INVENTION
The vasopressin (antidiuretic hormone, ADH, CYIQNCPRG) is a 9-amino acid peptide hormone produced by the magnocellular neurons of the paraventricular (PVN) and supraoptic (SON) nuclei of the hypothalamus and secreted directly into the posterior lobe of the pituitary gland where the hormone is stored until entering into the bloodstream. In the periphery, the major rôle of vasopressin is in the contraction of blood vessels, as well as in glucose metabolism and in the régulation of excrétion.
For this reason, the conditions due to inappropriate sécrétion of vasopressin thus the lack of vasopressin may lead to pathological changes in the body, such as the central form of diabètes insipidus or abnormally low blood pressure (hypotension), while in the case of elevated levels of vasopressin or exogenous administration various forms of strengthening of the aggressive behaviour can be observed (Ferris et al., BMC Neuroscience 2008, 9:111).
Oxytocin (OXT, CYIQNCPLG) is a vasopressin-related peptide hormone, differing from that in one amino acid and its receptor is also related to vasopressin receptors. The effects of compounds on the oxytocin receptor show species-specific différences, but the oxytocin hormone itself is identical in the different mammalian species. Similarly, the vasopressin peptide is the same in ail mammals (except marsupials and pigs) and the effects exerted through its receptors may also show species-specific différences. The anxiolytic effect of oxytocin exerted in the central nervous System is well-known (Neumann ID. J
Neuroendocrinol 2008, 20(6): 858-65), therefore the inhibition of the oxytocin receptor in the centrai nervous system can trigger anxiety as undesirable side effect.
Three vasopressin receptors are distinguished, ail of them are G-protein coupled receptors. The V1a receptor (V1aR) is expressed centrally in the cérébral cortex, hippocampus and pituitary gland, furthermore peripherally in the liver, vascuiar smooth muscle, lung, utérus and testes (Frank et ai., Eur J Pharmacol 2008, 583:226-42). The V1b receptors (V1bR) are also can be found in the cortex, hippocampus and pituitary gland, and in the periphery they play an important rôle in the régulation of the pancréas and the adrenal glands. In contrast to this, the V2 receptor (V2R) is mainly tocalised on the periphery, in the kidneys where it increases water reabsorption, thereby exerting the antidiuretic effect of vasopressin (Robben et al., Am J Physiol Penal Physiol 2007, 292(1): F253-60). Thus, due to changes in the régulation of water balance the effect on the V2 receptor may cause undesirable side effect.
The secondary signalling pathway of V1a and V1b receptors include the change of intracellular Ca2+ concentration through phosphatidylinositol, whereas the V2 receptors activate adenylate cyclase enzyme and influence cAMP levels (Gouzenes et al., J Physiol 1999, 517(Pt3):771-9; Tahara et al., Pflugers Arch 1999, 437(2):219-26).
An important rôle is attached to the V1a receptors in the régulation of the circadian rhythm. One-third of the neurons in the suprachiasmatic nucléus (SCN) express vasopressin and the mRNA of V1a receptors exhibit daily fluctuations in this brain région of which the highest values can be observed during night hours (de Vries and Miller, Prog Brain Res 1998, 119:3-20). Vasopressin shows sexual dimorphism in inducing behavioural effects, despite the fact that distribution and amount of the V1aR mRNAs do not differ in men and women (Szot et al., Brain Res Mol Brain Res 1994, 24(1-4):1-10). Experiments in mice hâve shown that the increased water absorption prior to their sleep period was triggered by their internai clock and not their physiologicai necessities (Gizowski et al., Nature 2016, 537(7622):6858). Sleep disorder is a major accompanying symptom of autism (Glickman, Neurosci Biobehav Rev 2010, 34(5):755-68).
Vasopressin acts as a neuromodulator in the brain, its elevated leve! can be detected in the amygdala under stress (Ebner et al., Eur JNeurosci2002, 15(2):384-8). Such stressful life situations are well known to increase the likeîihood of developing dépréssion and anxiety (Kendler et al, Arch Gen Psychiatry 2003, 60(8):789-96; Simon et al., Recent Pat CNS Drug Discov, 2008, 3(2):77-93; Egashira et al., JPharmacol Sci2009, 109(1):44-9; Bielsky et al., Neuropsychopharmacology 2004, 29(3):483-93). The expression of V1aR is high in the brain, especially in certain parts of the limbic system, such as the amygdala, the latéral septum and the hippocampus which play an important rôle in the development of anxiety. Male V1aR gene knocked out mice exhibited reduced anxiety in the elevated plus maze, the open field and the light-dark box tests, but these différences could not be detected in females (Bielsky et al., Behav Brain Res 2005, 164(1):132-6).
The male V1aR knockout mice did not show any phenotypic différence in motor performances. In normal light-dark-cycle experiments, V1aR KO mice showed no différence compared to their wild-type littermates, however, in the experiments carried out in continuous darkness the diurnal rhythm of V1a knockout mice was shifted significantly (Egashira et al., Behav Brain Res 2007, 178(1):123-7).
The V1aR KO mice showed modified activity in the prepulse inhibition test, in the test which is accepted as animal model of sensory motor deficiency observed in most schizophrénie patients. Egashira et al hâve shown decreased function in the social interaction test, which is suitable to measure socio-cognitive behaviour of the V1aR KO mice in both sexes, but it was not observed after the treatment with antagonist (Bleickard et al., Psychopharmacology (Beri), 2009, 202:711-18).
Two microsatellite polymorphisme associated with autism could be determined in the case of variants of the AVPR1A gene encoding the V1a receptor (Kim et al., Mol Psychiatry 2002, 7:503-7; Yirmiya et al., Mol Psychiatry 2006, 11:488-94; Yang et al., Psychiatry Res, 2010, 178(1):199-201; Yang et al., Neurosci Lett 2010, 479(3):197-200). It also refers to a genetic connection that altered activation of amygdala could be detected in patients carrying two risk alleles in the V1aR gene. These modified receptors hâve been shown to be able to alter the activation threshold of amygdala during emotional facial récognition process (MeyerLindenberg étal., Mol Psychiatry 2009, 14:968-75).
Preclinical data also support the efficacy of VI aR antagonists in autism. A wideiy used and accepted animal model of autism is to study the behaviour of rats exposed to valproate (VPA) treatment in utero. The reduced social behaviour of VPA-treated animais could be reversed by the V1aR antagonist compound to the normal level. to a functional magnetic résonance imaging study it was also found that decreased perfusion values were restored by the V1aR antagonist in different brain régions of prenatally VPA-treated animais. The decreased function of the cortex, the inferior colliculus, the hippocampus and the hypothalamus was increased by treatment with the V1aR antagonist, whereas in the ventral tegmentum, the striatum and the colliculus superior, the augmented perfusion was normalised by the V1aR antagonist (Grundschober et al., Poster presented at Annuel Meeting of the American Collège of Neuropsychopharmacology, 2014, Phoenix, USA). For this reason, V1aR antagonist compounds showing favourable blood-brain barrier pénétration are expected to be advantageous.
Influencing V1aR with smal! molecufe antagonists is a promising strategy for the treatmentofvarious pathological conditions ofthefemale sex organs (such as, but not limited to, dysmenorrhea, sexual dysfonction), long-lasting pathological conditions in blood pressure control (such as, but not limited to, hypertension and/or chronic heart failure), conditions resulting from inappropriate sécrétion of vasopressin (such as, but not limited to, diabètes insipidus, rénal failure, nephrotic syndrome and cirrhosis). It can be considered another promising strategy in the treatment of anxiety, dépréssion, aggression, and disorders of the central nervous system where one of the symptoms and/or syndromes of the disease may be related to the latter three diseases or show comorbidity with them. These include, but not limited to, autistic spectrum disorder (well-functioning autism, Asperger's syndrome, Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS), autism spectrum disorder (ASD) and its various syndromic forms: fragile X syndrome, Prader-Wiili syndrome, Rett syndrome, tuberous sclerosis), obsessive compulsive disorder (OCD), various forms of Down syndrome and post-traumatic stress disorder (PTSD). VI aR antagonists are also suitable for the treatment of aggressive behavioural disorders and/or irritability (such as, but not limited to, patients with ASD, or suffering from Huntingtoris disease (HD) or various forms of schizophrénie), behavioural hyperactivity disorders (such as, but not limited to, attention déficit hyperactivity disorder (ADHD)), cognitive disorders (such as, but not limited to, dementia, mild cognitive disorders (MCI), cognitive impairment associated with schizophrénie (CIAS), and Alzheimer’s disease), and other neuropsychiatrie disorders (such as, but not limited to, schizophrenia and associated diseases).
Many patent applications deal with V1a receptor antagonists, for example, Otsuka discloses benzoheterocyclic dérivatives (WO 95/034540 A1, WO 2009/001968 A1, WO 2011/052519 A1), Astellas Pharma (Yamanouchi) discloses condensed benzodiazépine and triazole dérivatives (WO 95/03305 A1, WO 01/87855 A1, WO 02/44179 A1), AbbVie discloses oxindole dérivatives (WO 2006/072458 A2, WO 2006/100082 A2), Bayer Pharma discloses aryl- or heteroaryltriazole dérivatives (WO 2017/191102 A1, WO 2017/191107 A1, WO 2017/191114 A1). Various benzoazulene core containing dérivatives (WO 2005/068466 A1, WO 2006/021213 A2, WO 2006/021882 A1, WO 2011/114109 A1, WO 2011/128265 A1, WO 2011/141396 A1, WO 2014/127350 A1), spiroindolinone and indolylcarbonyl dérivatives (WO 97/15556 A1, WO 2007/009906 A1, WO 2007/014851 A2) are also described as V1a receptor antagonists.
The first clinical developments considérées the V1a receptor as peripheral target, the poor brain pénétration was therefore bénéficiai in the development of compounds. Such was Sanofi’s indoline core compound, relcovaptan (SR-49059, WO 93/03013 A1), which was developed until the Phase 2 clinical trial. Among the indications studied were prématuré birth, pelvic pain observed during the menstruation, dysmenorrhea (Brouard et al., Br J Obstetr Gynaecol 2000, 107:614-9), heart failure, hypertension, and coronary spasm, but itwas also tested as an antineoplastic agent in small-ceil lung carcinoma until the last clinical trial was stopped in 2003 (Serradeil-Le Gai et al., Prog Brain Res 2002, 139:197-210; Adislnsight: Relcovaptan - Latest Information Update: 03 Oct
2006 http://adisinsiqht.sprinaer.com/druqs/800004942). Relcovaptan has been in clinical development since 1993 and it is the most frequently used in vitro tool in the V1aR research (Tahara et al., Br J Pharmacol 2000, 129:131-9).
Pfizer studied its triazole dérivative PF 00738245 (WO 2005/063754 A1) and compound PF-184563 of triazolobenzodiazepine cote (WO 2004/074291 A1) in preclinical development for dysmenorrhea, based on measured data these are efficient V1aR antagonists (Russell et al., Eur. J Pharmacol, 2011, 670(2): 347-355; Johnson et al., Bioorg Med Chem Left 2011, 21:5684-7) buttheir development was terminated.
By the examination of effects exerted on the central nervous system, the treatment of dépréssion and anxiety has also been raised as a novel therapeutic area. Johnson & Johnson’s compound JNJ-17308616 of spirobenzazepine core was one of the first central nervous system acting V1aR antagonist compound (Bleickard et al., Psychopharmacology (Ber!.), 2009, 202:711-18; WO 02/02531 A1) which demonstrated efficacy in a variety of different animal models used for anxiety research: significantly reduced anxiety behaviour in the elevated plus maze test, marble burying test, and in the separation-induced ultrasonic vocalisation of rat pups. Although it proved to be effective in influencing the elevated Olabyrinth and the conditioned lick response, due to its poor metabolic stability measured in rodents, its efficacy was not good and was measurable only at high doses and therefore it was difficult to test.
Azevan’s V1aR antagonist azetidone dérivatives, SRX246 and SRX251 (also known as API246 or API251, WO 03/031407 A2) also reached the clinical trial phase. Clinical trials of SRX246 are also currently ongoing for the treatment of aggression, and intermittent explosive disorder and irritability in Huntington's Disease and post-traumatic stress disorder, as well as in the human behavioural models of anxiety and fear (Adislnsight: SRX 246 Latest information Update: 16 Feb 2017 http://adisinsight.springer.com/druqs/800023656). Clinical triai was conducted with SRX251 to treat dysmenorrhea but both Phase 1 studies were discontinued in 2016 and similarly to SRX246 it was also investigated for aggression in the preclinical development (Adislnsight: SRX 251 - Latest Information Update: 04 Nov 2017 http://adisinsiQht.sprinqer.com/driiQs/800025117). SRX-246 and SRX-251 are active on the human V1a receptor and in rats both compounds were détectable in the brain at approximately 100-fold of the effective concentrations detected in the binding assay (Guillon et al., Bioorg Med Chem 2007, 15:2054-80; Fabio et al., J Pharm Sci2013, 102(6):2033-43).
Vantia’s V1aR antagonist compound, VA 111913 of pyrazolobenzodiazepine core (WO 2010/097576 A1; Adislnsight: VA 111913 - Latest information Update: 25 Aug 2015 http://adisinsiqht.sprinqer.com/druQs/800028777) was tested in Phase 2 clinical trial for the treatment of dysmenorrhea but there is no information about its development since 2015.
Otsuka’s V1aR antagonist, the quinolinone dérivative OPC 21268 (EP0382185A2; Adislnsight: OPC 21268 - Latest Information Update: 06 Oct
2006 http://adisinsiahtsprinQer.com/druqs/800000284) was tested for the indication of gastric mucosal damage indication in the preclinical phase, whereas in Phase 2 clinical trials it was studied for heart failure and hypertension but there is no information on its development since 2015 (Yamamura et al., Science 1991, 252:572; Serradeil-Le Gai et al., J Clin invest 1993, 92(1):224).
When examining the brainstem in post mortem human samples sélective localisation of Via receptors unrelated to oxytocin receptors could be detected in the nucléus prepositus, which plays a rôle in eye gaze stabilisation (Freeman et ai., Soc Neurosci 2017, 12(2): 113123). A fundamental skill required for human social behaviour is the récognition and eyetracking of biologically relevant information (Klin et al., Nature 2009, 459:257-63, Simion et al., PNAS 2008, 105(2):809-13). The most active V1aR researcher Hoffmann-La Roche reached Phase 1 study with their indole dérivative RO5028442 (RG-7713; WO 2007/006688 A1 ), where positive effect on the orientation of eye-gaze pattern could be detected in humans (Umbricht et al., Neuropsychopharmacology 2017, 42 (9):1914-1923; Adislnsight: RG 7713 - Latest Information Update: 05 Nov 2015 http://adisinsight.springer.com/drugs/800043668). Phase 2 clinical trials for the treatment of autism are currently ongoing with balovaptan of the triazolobenzodiazepine core (RG-7314, RO5285119; WO 2010/060836 A1; Adislnsight: RG 7314 - Latest Information Update: 10 Sep
2017 http://adisinsight.springer.com/drugs/800035102).
Despite the numerous V1aR antagonist compounds and clinical studies, unmet medical need still persists to develop a V1aR antagonist that is suitable for the treatment and/or prophylaxis of various pathological conditions of thefemale sexorgans, long-standing conditions in blood pressure control, conditions resulting from inappropriate sécrétion of vasopressin, anxiety, dépréssion, aggression, disorders of the central nervous System where one of the symptoms and/or syndromes of the disease may be related to anxiety, dépréssion, aggression or show comorbidity with them (autistic spectrum disorder, obsessive compuisive disorder, various forms of Down syndrome, post-traumatic stress disorder), aggressive behavioural disorders and/or irritabiiity, behavioural hyperactivity disorders, cognitive disorders or other neuropsychiatrie disorders.

Subsequently, the optically active bases or acids are liberated from the separated diastereoisomeric salts. Varions methods of separating opticai isomers include chiral chromatography (e.g., chiral HPLC columns) optionally used by derivatization with the aim to maximize the séparation of enantiomers. Appropriate chiral HPLC columns are Diacel columns, such as CHIRALPAK or CHIRALCEL columns, which can be routinely chosen as desired. Where applicable, enzymatic séparations carried out by derivatization may also be used. The optically active compounds of general formula (!) can also be prepared using optically active starting materials using chiral synthesis without racemization reaction conditions.

Human vasopressîn V1a receptor binding assay
Cells and radioligand
The immortalized 1321N1 cell line (Perkin Elmer, ES-361-M400-UA) constitutively and stably expressing human vasopressîn V1a receptor and vasopressîn (8-L-Arginîne), [Phenylalanyl-3,4,5-3H(N)] labelled compound (Perkin Elmer Life and Analytical Sciences) as radioligand were used to détermine the affinity of the prepared compounds.
Method
Membrane-preparation: Membrane préparation of immortalized 1321N1 cells expressing the propagated human Vasopressîn V1a receptor was made according to Jarvis’s method (Jarvis et al., J Pharmacoi Exp Ther 2004, 310:407-16). Cells were suspended in préparative buffer (50 mM Tris, 1 mM EDTA, 0.1 mM PMSF) and homogenized with glass homogenizing potter. To separate the raw membrane fraction two consecutive centrifugation procedures (40,000 g for 20 minutes at 4°C) were executed, then the membrane was taken into the preparatory buffer during a final washing step, it was dîvîded into aliquots which were stored at -80°C untîl the time of measurement.
The protein content of the prepared membrane was determined according to Lowry’s method using standard dilution line of bovine sérum albumin (BSA) (Lowry et a!., J Biol Chem 1951, 193:265-75).
Receptor binding test: In the receptor binding assay, the substances with unknown affinity were used at a minimum of 8 different concentrations, with 3 parallèle at each concentration. To détermine the final affinity value, the results of at least two indépendant experiments were taken into account. The assay mixture included the incubation buffer (50 mM Tris-HCI, pH 7.4 + 3% BSA), membrane préparation of 1321N1 cells expressing the human Vasopressîn V1a receptor (167 pg/ml) and Vasopressîn (8-L-Arginine), [Phenylalanyl-3,4,5-3H(N)] as radioligand (1 nM).
Non-specific binding values were determined în the presence of unlabelied 1.2x10’6 M (Arg8)-vasopressin. Samples were incubated in a total volume of 0.33 ml for 60 minutes at 27°C. Membrane-bound and free ligands were separated by filtration through a 0.5% poiyethyleneimîne-impregnated UniFilter® GF/B™. After drying the filter plates, 40 pl Microscînt-20 (Packard) scintillation cocktail was added to the samples. Finally, radîoactîvîty was measured using MîcroBeta2 Microplate Counter (Perkin Elmer).
The ICso data (i.e. theconcentration ofthe unknown substancewhich displaces 50% of spécifie bound radioligand) is calculated from the concentration-displacement curve using the sigmoid fitting mathematical method y = (A1-A2)/(1+(x/xo)p)+A2 with Origin 7.5. software (OriginLab Corporation, Northampton, USA). During fitting, the asymptotes are not fixed. The Ki values (inhibition constant) are given with Cheng-Prusoff équation Ki = ICso/[1+(L/KD)] wherein [L] is the radioligand concentration used in the experiment and [Kd] is the affinity of the radioactively labelled ligand for the given receptor. The KD is determined beforehand using the Scatchard curve.
Functional assay to test compounds on human vasopressin V1a receptor expressing cell line
Cells
The immortalized 1321N1 cell line (Perkin Elmer, ES-361-M400-UA) constitutively and stably expressing human vasopressin V1a receptor were used to measure the prepared compounds. The ordinary secondary messenger pathway of the measured GPCR receptor was used, the endogenous Gq-associated System.
Method
Using 30,000 cells/plate, compounds were measured on 96-well plates. The buffer composition of the measurements was the following (expressed in mM): 140 NaCI, 5 KCI, 2 CaCI2, 2 MgCh, 10 glucose, 10 HEPES (4-(2-hydroxyethyl)-1-piperazine-ethanesulfonic acid), 2 probenecid, pH = 7.4. FLIPR Calcium 5 kit (Molecular Devices) was used as fluorescent dye, the medium was not removed prior to filling with the dye and the cells were not washed out either before or after: The incubation was performed at room température, the final concentration of DMSO was 1%. The materials to be measured were administered in 15 to 20 minutes pretreatment, at least two parallels of each compound in each concentration was measured.
Fluorescence signal was used to détermine the intracellular Ca2+ level, the reader was FlexStation II96. Cytoplasmic Ca2+ concentrations were measured by fluorometry using the FlexStation II96 plate reader (excitation: 485 nm, émission: 525 nm). The fluorescence signal was logged in every 1.4 seconds for 1 minute. The reference compounds used were the following: (Arg8)-vasopressin as agonist at concentration of ECeo, determined for each plate, and relcovaptan as antagonist at 1 μΜ. The % of inhibition at each concentration and the IC50 value of the compounds were determined where a concentration line was also measured.
The total AVP concentration-response curve was recorded on each plate. The effect of compounds measured was expressed by percentage of relative inhibition compared to control response. For the graphie représentation of the data, nonlinear four parameter alignments were applied using SoftMaxPro software according to the following formula: y = 5 A-D/(1+(x/C)AB)+D, wherein: A = 0 and D = 100 - lower / upper fixed asymptotes, y = percentage of inhibition, x = logarithm of concentrations of the tested compound, B = steepness of curve and C - IC50 (the concentration belonging to the 50% inhibition of the control response). The average IC50 values were calculated from at least three independent measurements in ail cases.

Mouse vasopressin V1a receptor binding assay
Cells and radioligand
The immortalized 1321N1 cell line (B9/1321N1 clone) constitutively and stably expressing mouse vasopressin V1a receptor vasopressin (8-L-Arginine), [Phenylalanyl3,4,5-3H(N)] labelled compound (Perkin Elmer Life and Analytical Sciences) as radioligand were used to détermine the affinity of the prepared compounds.
Method
Membrane-preparation: Membrane préparation of immortalized 1321N1 cells expressing the propagated mouse Vasopressin V1a receptor was made according to Jarvis’s method (Jarvis et al., J Pharmacol Exp Ther 2004, 310:407-16). Cells were suspended in préparative buffer (50 mM Tris, 1 mM EDTA, 0.1 mM PMSF) and homogenized with glass homogenizing potter. To separate the raw membrane fraction two consecutive centrifugation procedures (40,000 g for 25 minutes at 4°C) were executed, then the membrane was taken into the preparatory buffer during a final washing step, it was divided into aliquots which were stored at -80°C until the time of measurement
The protein content of the prepared membrane was determined according to Lowry’s method using standard dilution line of bovine sérum albumin (BSA) (Lowry étal., J Biol Chem 1951, 193:265-75).
Receptor binding test: In the receptor binding assay, the substances with unknown affinity were used at a minimum of 8 different concentrations, with 3 parallèle at each concentration. To détermine the final affinity value, the results of at least two independent experiments were taken into account. The assay mixture included the incubation buffer (50 mM Tris-HCI, pH 7.4 + 3% BSA), membrane préparation of 1321N1 cells expressing the mouse vasopressin V1a receptor (152 pg/ml) and vasopressin (8-L-Arginine), [Phenylalanyl3,4,5-3H(N)] as radioligand (~ 35-50% concentration of Kd).
Non-specific binding values were determined in the presence of an unlabelled 1.2x10' 6 M (Arg8)-vasopressin. Samples were incubated in a total volume of 0.33 ml for 60 minutes at 27°C. Membrane-bound and free ligands were separated by filtration through a 0.5% polyethyleneimine-impregnated UniFilter® GF/B™. After drying the filter plates, 40 pl Microscint-20 (Packard) scintillation cocktail was added to the samples. Finally, radioactivity was measured using MicroBeta2 Microplate Counter (Perkin Elmer).
The radioligand clamping ability of a substance is determined in at least two independent experiments. Spécifie radioligand binding can be defined as the différence between total and non-specific binding in the presence of a saturation amount of the unlabelled ligand or different concentrations of the substance to be tested. The results are given as a percentage of inhibition of the spécifie binding achieved in the presence of the substance to be tested.
The IC50 data (i.e. the concentration ofthe unknown substancewhich displaces 50% of spécifie bound radioligand) is calculated from the concentration-displacement curve using the sigmoid fitting mathematical method y = (A1-A2)/(1+(x/xo)p)+A2 with Origin 7.5. software (OriginLab Corporation, Northampton, USA). During fitting, the asymptotes are not fixed. The Ki values (inhibition constant) are given with Cheng-Prusoff équation Ki = ICso/[1+(L/Kd)] wherein [L] is the radioligand concentration used in the experiment and [Kd] is the affinity of the radioactively labelled ligand for the given receptor. The Kd is determined beforehand using the Scatchard curve.

Functional V1a in vivo test
Animais
Male mice (NMRI, ToxiCoop) weighing 18-40 g were used. Animais were kept at least 5 days after delivery, during housing and measurements they were fed and drink ad libitum. The experiments were permitted by the Local Animal Protection Committee and carried out in accordance with the European Animal Protection Directives (EU Directive 2010/63/EU).
Method
Animal behaviour was measured by an automated behavioral analysis System (LABORAS™). The sensors located below platforms detect the mechanical vibration generated by the movement of animal, and transform into an electrical signal (Quinn et al., J Neurosci Methods 2003, 130:83-92). After analyzing signais, the System analyzes the time spent with the following behavioral parameters: locomotion, immobility, climbing, grooming. The grooming algorithm by définition is able to measure the scratching behavioral response. During the experiment, mice were pretreated with the test substance or vehicle, and after the pretreatment period scratching-inducing compound (s.c. 0.3 mg/kg oxytocin) was administered, and then the animais were individually placed into measuring cages. Their behaviour was observed for 1 hour. To reduce the exploratory activity, the animais were measured after a 1-hour habituation to the cage. The behavioural parameters were compared to the parallel measured parameters of the control animais.
The behavioural inhibitory effect of the substances was calculated with average values of parallel measured vehicle treated groups and presented as the percentage of inhibition: 0% was expressed as average value of scratching behaviour of vehicle pretreated animais (and phys. saline s.c. pretreated with vehicle), while 100% was expressed as average value of scratching of vehicle pretreated animais that received oxytocin subcutaneously. For statistical analysis one-way analysis of variance (ANOVA) with Tukey post hoc test were used.
Surprisingly, it has been found that certain compounds of the présent invention produced significant effect on the mouse V1a receptor in vivo functional test.

The prénatal valproate model of autism spectrum disorder (ASD) in rats
The prénatal valproate model has excellent construct and face validity, thus it is a widely accepted animal model of ASD (Christensen et al, JAMA 2013, 309:1696-1703; Roullet et al, Neurotoxicol Teratol. 2013, 36:45-56). In this model, time-mated female Wistar rats (Harlan, UK) were treated with single-dose of valproic acid (VPA, i.p. 600 mg/kg) on 12.5 days of pregnancy. After birth and séparation, the examined male offsprings were kept under standard laboratory conditions until completion of the studies. Four animais were kept together in standard cages at 22-24°C external température and in 12-12 hour light-dark cycle (07.30 a.m. -07.30 p.m.). Food and water were available ad libitum. After once daily treatment with the test substance for 7 days and pretreatment on the day of measurement, the behaviour of the rats was assessed in the social preference test on the 59,h or 60th postnatal day. The social preference test is a largely accepted test method for determining the autistic behaviour of rodents (Nadler et al, Genes Brain Behav20Q4, 3:303-314; BambiniJunior et al, Brain Res 2011, 1408:8-16). The test consists of two paradigms, the first is the social approach avoidance test. In this paradigm the social behaviour of examined animais can be determined with a spécial three-chamber apparatus. In the apparatus, the contact behaviour of the conspecific and empty separated area surrounded with a perforated wall can be examined and compared. Prenatally valproate-treated rats produce autistic behaviour and spend significantly less time with seeking response toward conspecific than the in utero vehicle-treated control animais. One day later, on the 60th postnatal day, rats were tested in the social memory and récognition paradigm. In this, the contact behaviour with a new, previously unknown conspecific can be measured compared to a familiar conspecific.
In the social approach avoidance paradigm valproate treated rats (VPA/VEH) showed significant decrease of active time spent with social behaviour compared to the in utero vehicle-treated control animais (VEH/VEH). Certain 5,6-dihydro-4H-[1,2,4]triazolo[4,3a][1]benzazepine compounds of the présent invention substituted at position 5 were unexpectedly effective in this assay and the treatment statistically significantly reversed the value of VPAA/EH to the value of VEH/VEH treated animais.
Rats treated with SAHA (suberoil anilide or vorinostat) used as positive control also showed statistically significant increase in time spent with social seeking response (Foley et al, Eur J Pharmacol 2014, 727:80-86).
In the social memory récognition paradigm valproate treated rats showed significant decrease of the active time spent with seeking new, non-familiar animal compared to the in utero vehicle-treated control animais. Certain 5,6-dihydro-4H-[1,2,4]triazolo[4,3a][1]benzazepine compounds of the présent invention substituted at position 5 made the behaviour of animais more socialized and were capable to significantly increase the active time spent with seeking response from the new animais. Unexpectedly, the treatment reversed the value of VPA/VEH to the value of VEH/VEH treated animais. Rats treated with SAHA used as positive control also showed statistically significant increase in the time spent with seeking response.
Certain compounds of the présent invention therefore exhibited signifïcant behavioral benefits in the présent animal model that implies the clinical symptoms of ASD, thus providing a therapeutic opportunity for the treatment of human ASD symptoms.
