This application is a reissue application of U.S. Pat. No. 6,903,120, issued Jun. 7, 2005 from U.S. Ser. No. 10/168,173, filed Nov. 21, 2002, which was a §371 national stage of PCT International Application No. PCT/SE00/02674, filed Dec. 22, 2000, which claims priority of Swedish Patent Application No. 9904724-3, filed Dec. 22, 1999.
FIELD OF THE INVENTION
The present invention relates to new modulators of dopamine neurotransmission, and more specifically to new substituted 4-(phenyl N-alkyl)-piperazines and 4-(phenyl N-alkyl)-piperidines, and use thereof.
BACKGROUND OF THE INVENTION
Dopamine is a neurotransmitter in the brain. Since this discovery, made in the 1950s, the function of dopamine in the brain has been intensely explored. To date, it is well established that dopamine is essential in several aspects of brain function including motor, cognitive, sensory, emotional and autonomous (e.g. regulation of appetite, body temperature, sleep) functions. Thus, modulation of dopaminergic function may be beneficial in the treatment of a wide range of disorders affecting brain functions. In fact, both neurologic and psychiatric disorders are treated with medications based on interactions with dopamine systems and dopamine receptors in the brain.
Drugs that act, directly or indirectly, at central dopamine receptors are commonly used in the treatment of neurologic and psychiatric disorders, e.g. Parkinson's disease and schizophrenia. Currently available dopaminergic pharmaceuticals have severe side effects, such as extrapyramidal side effects and tardive dyskinesia in dopaminergic antagonists used as antipsychotic agents, and dyskinesias and psychoses in dopaminergic agonists used as anti-Parkinson's agents. Therapeutic effects are unsatisfactory in many respects. To improve efficacy and reduce side effects of dopaminergic pharmaceuticals, novel dopamine receptor ligands with selectivity at specific dopamine receptor sub-types or regional selectivity are sought for. In this context, also partial dopamine receptor agonists, i.e. dopamine receptor ligands with some but not full intrinsic activity at dopamine receptors, are being developed to achieve an optimal degree of stimulation at dopamine receptors, avoiding excessive dopamine receptor blockade or excessive stimulation.
Compounds belonging to the class of substituted 4-(phenyl-N-alkyl)-piperazine and substituted 4-(phenyl-N-alkyl)-piperidines have been previously reported. Among these compounds, some are inactive in the CNS, some display serotonergic or mixed serotonergic/dopaminergic pharmacological profiles while some are full or partial dopamine receptor agonists or antagonists with high affinity for dopamine receptors.
A number of 4-phenylpiperazines and 4-phenylpiperidine derivatives are known and described, for example Costall et al. European J. Pharm. 31, 94, (1975), Mewshaw et al. Bioorg. Med. Chem. Lett., 8, 295, (1998). The reported compounds are substituted 4-phenylpiperazine's, most of them being 2-, 3- or 4-OH phenyl substituted and displaying DA autoreceptor agonist properties.
Fuller R. W. et al, J. Pharmacol. Exp. Therapeut. 218, 636, (1981) disclose substituted piperazines (e.g. 1-(m-trifluoromethylphenyl)piperazine) which reportedly act as serotonin agonists and inhibit serotonin uptake. Fuller R. W. et al, Res. Commun. Chem. Pathol. Pharmacol. 17, 551, (1977) disclose the comparative effects on the 3,4-dihydroxyphenylacetic acid and Res. Commun. Chem. Pathol. Pharmacol. 29, 201, (1980) disclose the comparative effects on the 5-hydroxyindole acetic acid concentration in rat brain by 1-(p-chlorophenol)-piperazine.
Boissier J. et al Chem Abstr. 61:10691c, disclose disubstituted piperazines. The compounds are reportedly adrenolytics, antihypertensives, potentiators of barbiturates, and depressants of the central nervous system.
A number of different substituted piperazines have been published as ligands at 5-HT1A receptors, for example Glennon R. A. et al J. Med. Chem., 31, 1968, (1988), van Steen B. J., J. Med. Chem., 36, 2751, (1993), Mokrosz, J. et al, Arch. Pharm. (Weinheim) 328, 143-148 (1995), and Dukat M.-L., J. Med. Chem., 39, 4017, (1996). Glennon R. A. discloses, in international patent applications WO 93/00313 and WO 91/09594 various amines, among them substituted piperazines, as sigma receptor ligands. Clinical studies investigating the properties of sigma receptor ligands in schizophrenic patients have not generated evidence of antipsychotic activity, or activity in any other CNS disorder. Two of the most extensively studied selective sigma receptor antagonists, BW234U (rimcazole) and BMY14802, have both failed in clinical studies in schizophrenic patients (Borison et al, 1991, Psychopharmacol Bull 27(2): 103-106; Gewirtz et al, 1994, Neuropsychopharmacology 10:37-40).
Further, WO 93/04684 and GB 2027703 also describe specific substituted piperazines useful in the treatment of CNS disorders.
SUMMARY OF THE INVENTION
The object of the present invention is to provide new pharmaceutically active compounds, especially useful in treatment of disorders in the central nervous system, which do not have the disadvantages of the above described substances.
In the work leading to the present invention, it was found that it is desired to provide substances with specific pharmacological properties, namely substances that have modulating effects on dopamine neurotransmission. These properties have not been described earlier, and they are not possible to obtain with the earlier known compounds. The compounds according to the present invention have a very surprising and interesting dualistic dopaminergic action profile with antagonist-like effects on brain neurochemistry and mild agonist-like effects on normal behavior, but they induce inhibition of behavior in states of hyperactivity.
The present invention thus relates to new 3-substituted 4-(phenyl-N-alkyl) piperazines and 3-substituted 4-(phenyl-N-alkyl) piperidines in the form of free base or pharmaceutically acceptable salts thereof, pharmaceutical compositions containing said compounds and use of said compounds in therapy.
One subject of the invention is to provide new compounds for therapeutic use, and more precisely compounds for modulation of dopaminergic systems in the mammalian brain, including human brain.
Another subject of the invention is to provide compounds with therapeutic effects after oral-administration.
More precisely, the present invention relates to 3-substituted 4-(phenyl N-alkyl)-piperazine and 4-(phenyl-N-alkyl)-piperidine compounds of Formula 1:
Figure USRE046117-20160823-C00002
  • and pharmaceutically acceptable salts thereof, wherein:
  • X is selected from the group consisting of N, CH, and C, however X may only be C when the compound comprises a double bond at the dotted line;
  • R1 is selected from the group consisting of OSO2CF3, OSO2CH3, SOR3, SO2R3, COR3, NO2, and CONHR3, wherein R3 is as defined below, and when X is CH or C R1 may also be selected from the group consisting of CF3, CN, F, Cl, Br, and I;
  • R2 is selected from the group consisting of C1-C4 alkyls, allyls, CH2SCH3, CH2CH2OCH3, CH2CH2CH2F, CH2CF3, 3,3,3-trifluoropropyl, 4,4,4-trifluorobutyl, and —(CH2)—R4, wherein R4 is as defined below;
  • R3 is selected from the group consisting of C1-C3 alkyls, CF3, and N(R2)2, wherein R2 is as defined above;
  • R4 is selected from the group consisting of C3-C6 cycloalkyls, 2-tetrahydrofurane and 3-tetra-hydrofurane.
The compounds according to the present invention possess dopamine-modulating properties and are useful in treating numerous central nervous system disorders including both psychiatric and neurological symptoms.
Diseases in which compounds with modulating effects on dopaminergic systems may be beneficial are in disorders related to ageing, for preventing bradykinesia and depression and for the improvement of mental functions. They may also be used to improve cognitive functions and related emotional disturbances in neurodegenerative and developmental disorders as well as after brain damage.
The compounds according to the invention can be used to improve all symptoms of psychosis, including schizophrenia and schizophreniform disorders as well as drug induced psychotic disorders. The compounds according to the invention may also be used in behavioral disorders usually first diagnosed in infancy, childhood, or adolescence as well as in impulse control disorders. Also, speech disorders such as stuttering may improve. They may also be used for treating substance abuse disorders as well as disorders characterized by misuse of food.
Mood and anxiety disorders, personality disorders, and conversion hysteria may also be treated with the compounds according to the invention.
Neurological indications include the treatment of Huntington's disease and other movement disorders as well as movement disorders induced by drugs. Restless legs and related disorders as well as narcolepsy may also be treated with compounds included according to the invention. They may also improve mental and motor function in Parkinson's disease, and in related parkinsonian syndromes. They may also be used to ameliorate tremor of different origins. They may be used in the treatment of headaches and used to improve brain function following vascular or traumatic brain injury. Moreover, they may be used to relieve pain in conditions characterized by increased muscle tone.
The compounds according to the present invention have unexpectedly been found to act specifically on dopaminergic systems in the brain. They have effects on biochemical indices in the brain with the characteristic features of selective dopamine antagonists, e.g. producing increases in concentrations of dopamine metabolites.
Yet, dopamine receptor antagonists characteristically suppress behavioral activity and induce catalepsy, while the compounds of this invention show no, or only limited, inhibitory effects on spontaneous locomotion. In contrast they may induce a slight behavioral activation with concomitant increases in small-scale movements, e.g. stops in the center of the behavior recording arena, similar to that induced by dopaminergic agonists. The behavioral activation is limited, not reaching the profound increases in activity induced by direct or indirect dopaminergic agonists. On the other hand, the preferred substances reduce the increase in activity induced by direct or indirect dopaminergic agonists, i.e. d-amphetamine and congeners.
Thus, the compounds of this invention surprisingly show an interesting dualistic dopaminergic action profile with antagonist like effects on brain neurochemistry and mild agonist like effects on normal behavior, but inhibition of behavior in states of hyperactivity. The action profile suggests modulatory effects on dopaminergic functions, clearly different from known compounds belonging to these chemical classes or effects anticipated of typical dopamine receptor antagonists or agonists from these or other chemical classes.
Given the involvement of dopamine in a large variety of CNS functions and the clinical shortcomings of presently available pharmaceuticals acting on dopamine systems, the novel class of dopaminergic modulators presented in this invention may prove superior to presently known dopaminergic compounds in the treatment of several disorders related to dysfunctions of the CNS, in terms of efficacy as well as side effects.
Some compounds according to the invention have been found to have surprisingly good pharmacokinetic properties including high oral bioavailability. They are thus suitable for the preparation of orally administered pharmaceuticals. There is no guidance in the prior art how to obtain compounds with this effect on dopamine systems in the brain.
DETAILED DESCRIPTION OF THE INVENTION
Pharmacology
Evidence is available that neurotransmission in the CNS is disturbed in psychiatric and neurologic diseases. In many instances, for example in schizophrenia or Parkinson's disease, pharmacotherapies based on antagonism or agonism at dopamine receptors are useful, but not optimal. In recent years much efforts have been put on finding novel and selective ligands for dopamine receptor subtypes (D1, D2, D3, D4, D5) with the aim to improve efficacy and reduce side effects.
The present invention offers another principle for novel therapeutics based on interactions with dopamine systems. The compounds according to the invention have effects on brain neurochemistry similar to antagonists at dopamine D2 receptors. In contrast to currently used dopamine receptor antagonists the compounds according to the invention show no or limited inhibitory effects on spontaneous locomotion. They may induce behavioral activation with concomitant increases in small-scale movements, e.g. stops in the center of the behavior recording arena, similar to that induced by dopaminergic agonists. The behavioral activation is limited, not reaching the profound increases in activity induced by direct or indirect dopamine receptor agonists. Surprisingly, the preferred substances can actually reduce the increase in activity induced by direct or indirect dopaminergic agonists, i.e. d-amphetamine and congeners.
The preferred structures are substituted in the meta position on the aromatic ring. An example of such a compound is methanesulfonic acid 3-(1-propyl-piperidin-4-yl)-phenyl ester, which is shown in Example 14 below. In rat, this compound increases 3,4-dihydroxyphenylacetic acid in the striatum from 1265±74 (controls) to 3208±236 ng/g tissue at 50 μmol/kg s.c. in combination with a slight increase in behavioral activity; 1485±328 cm/30 min (controls) to 2126±240 cm/30 min at 50 μmol/kg s.c., n=4. Another preferred example of a compound according to the invention is 4-(3-methanesulfonyl-phenyl)-1-propyl-piperidine, further illustrated in Example 6. In rat, this compound increases 3,4-dihydroxy-phenylacetic acid in the striatum from 914±19 (controls) to 1703±19 ng/g tissue at 50 μmol/kg s.c. This increase in dopamine turnover is followed by a trend towards an increase in motor activity from 2030±299 cm/60 min to 2879±398 cm/60 min p=0.14. In animals habituated to the motilitymeter box the compound described in Example 6, 4-(3-methanesulfonyl-phenyl)-1-propyl-piperidine, increases behavioral activity from 476±279 cm/60 min (controls) to 1243±72 cm/60 min, p<0.05, n=4, and 4-dihydroxyphenylacetic acid in the striatum from 975±23 (controls) to 2074±144 ng/g tissue at 50 μmol/kg s.c., p<0.05, n=4.
In addition, the compound described in Example 6, 4-(3-methanesulfonyl-phenyl)-1-propyl-piperidine, has the preferred ability to reduce behavioral activation induced by both d-amphetamine (1.5 mg/kg s.c.) and dizolcipine (Mk-801, 0, 7 mg/kg i.p.). d-Amphetamine hyperactivity is reduced from 10694±2165 cm/60 min to 1839±344 cm/60min, p<0.05 n=4, at 50 μmol/kg s.c. of the compound described in Example 6 and behavioral activation induced by dizolcipine (Mk-801) is reduced from 32580±4303 cm/60 min to 18197±1389 cm/60 min p<0.05, at 50 μmol/kg sc. Surprisingly, the compound described in Example 6 has an oral availability (F) of 85% in rat.
Unlike the somewhat similar compounds described in WO91/09594, the compound of Example 6, 4-(3-methanesulfonyl-phenyl)-1-propyl-piperidine, lacks affinity at the sigma receptor, <50% inhibition of [3H]-DTG binding (according to a method for measurement of sigma binding described by Shirayama Y. et al., 1993, Eur. J. Pharmacol. 237, p 117) at 10 μmol/L to rat brain membranes.
In order to demonstrate the surprising effects of the compounds according to the invention, some of the compounds have been compared to similar compounds according to prior art. The compounds-used for comparison with the compounds according to the invention in the comparative examples are thus not compounds according to the invention since they do not exhibit the desired properties.
COMPARATIVE EXAMPLE 1
4-(4-methanesulphonyl-phenyl)-1-propyl piperidine illustrates that substitution in the para position yields inactive compounds. 4-(4-methanesulphonyl-phenyl)-1-propyl piperidine has no effect on 3,4-dihydroxyphenyl-acetic acid in the striatum as demonstrated in the neurochemical experiment; 988±70 (controls) ng/g tissue and 928±51 ng/g tissue at 50 μmol/kg s.c. 4-(4-methanesulphonyl-phenyl)-1-propyl piperidine does not have the properties desired according to the invention.

To further illustrate the importance of the substitition on the aromatic ring for the desired properties, 4-phenyl-1-propyl-piperidine is demonstrated to lack activity in the behavioral assay in the non-pre-treated rat, 3661±494 cm/60 min, controls, to 2553±471 cm/60 min, p>0.05, n=4, at 33 μmol/kg and lacks effects on 3,4-dihydroxyphenyl-acetic acid in the striatum as demonstrated in the neurochemical experiment; 1027±31 (controls) ng/g tissue and 1190±70 ng/g tissue at 33 μmol/kg s.c., p>0.05., 4-phenyl-1-propyl-piperidine] also lacks the desired inhibition of behavioral activity in the d-amphetamine stimulated (17295±4738 cm/60 min, d-amphetamine, to 13764±2919 cm/60 min, n=4, p>>0.05 at 33 μmol/kg.
COMPARATIVE EXAMPLE 3
Further, 1-phenyl-4-propyl-piperazine, described as sigma receptor binding compound in WO91/09594, is found to reduce behavioral activity in the non-pre-treated animal, from 3370±227, controls, to 1923±204 cm/60 min, n=4, p<0.05 at 33 μmol/kg s.c., thus lacking the properties sought for.
COMPARATIVE EXAMPLE 4
Substitution in the ortho position as exemplified by 1-(2-methoxy-phenyl)-4-propyl piperazine yields a compound which increases 3,4-dihydroxyphenylacetic acid in the striatum from 1028±9 (controls) ng/g tissue to 3836±65 ng/g tissue at 50 μmol/kg s.c., p<0.05, n=4. This is followed by the behavioral inhibition not sought for in the present invention; 1651±300 cm/60 min (controls) to 67±34 cm/60 min, at 50 μmol/kg s.c., p<0.05, n=4.
COMPARATIVE EXAMPLE 5
The properties of the substituent in the meta position are important. 1-propyl-4-(3-triflouro-methyl-phenyl) piperazine increases 3,4-dihydroxyphenyl-acetic acid in the striatum from 1066±46 (controls) ng/g tissue to 3358±162 ng/g tissue at 50 μmol/kg s.c., p<0.05, n=4, however, followed by behavioral inhibition from 1244±341 cm/60 min (controls) to 271±137 at 50 μmol/kg s.c., p<0.05, n=4, thus, lacking the properties sought for in the present invention.
COMPARATIVE EXAMPLE 6
Further, the compound of 3-(4-Propyl-piperazine-1-yl)-benzonitrile increases 3,4-dihydroxyphenyl-acetic acid in the striatum from 1432±57 (controls) ng/g tissue to 4498±243 ng/g tissue at 100 μmol/kg s.c., p<0.05, n=4, and reduces 5-hydroxy-indole acetic acid from 630±16 (controls) ng/g tissue to 484±26 ng/g tissue at 100 μmol/kg s.c., p<0.05, n=4. These effects are followed by behavioral inhibition from 3959±688 cm/60 min (controls) to 634±266 at 100 μmol/kg s.c., p<0.05, n=4, thus, lacking the properties sought for in the present invention. 3-(4-Propyl-piperazine-1-yl)-benzonitrile has the following properties: m.p. 159° C. (fumarate) MS m/z (relative intensity, 70 eV) 229 (M+, 28), 200 (bp), 157 (27), 129 (22), 70 (25).

COMPARATIVE EXAMPLE 8
The physicochemical properties of the substituent on the basic nitrogen is also important for the desired profile. It is not possible to use any substituent, which is exemplified by 1-phenethyl-4-(3-trifluoromethyl-phenyl)-piperazine described as a sigma receptor ligand in WO 91/09594 and WO 93/00313 which has some effects on 3,4-dihydroxyphenylacetic acid in the striatum; 852±33 (controls) to 1406±77 ng/g tissue at 50 μmol/kg s.c., p<0.05, n=4, but also reduces both 5-hydroxyindoleacetic acid in the striatum from 358±20 (controls) to 289±16 ng/g tissue at 50 μmol/kg s.c., p<0.05, n=4, and serotonin (5-HT) from 379±10 (controls) to 282±6 ng/g tissue at 50 μmol/kg s.c., p<0.05, n=4, which is an undesired property according to this invention but in accordance with the reported IC50 of 20,3 nM at the 5-HT1A receptor (WO 93/00313).
COMPARATIVE EXAMPLE 9
In addition, 1-benzyl-4-(3-methanesulfonyl-phenyl)-piperidine and 3-(1-benzyl-piperidin-4-yl)-phenol, compounds with benzylic substitution on the basic nitrogen, both has the undesired property to interact with serotonin systems in the brain. 1-Benzyl-4-(3-methanesulfonyl-phenyl)-piperidine increases 5-hydroxyindoleacetic acid in the striatum from 428±20 (controls) to 487±7 ng/g tissue at 50 μmol/kg s.c., p<0.05, n=4, and reduces serotonin (5-HT) from 442±15 (controls) to 345±18 ng/g tissue at 50 μmol/kg s.c., p<0.05, n=4, and induces the serotonin behavioral syndrome (serotonin behavioral syndrome is e.g. described by Tricklebank et al., 1985, Eur. J. Pharmacol, 106, pp 271-282). 3-(1-Benzyl-piperidin-4-yl)-phenol has the undesired ability to increse 5-hydroxyindoleacetic acid in the striatum from 404±10 (controls) to 492±26 ng/g tissue at 50 μmol/kg s.c., p<0.05, n=4, and reduces serotonin in the limbic region (5-HT) from 734±8 (controls) to 677±20 ng/g tissue at 50 μmol/kg s.c., p<0.05, n=4.
COMPARATIVE EXAMPLE 10
Substitution on the basic nitrogen according to 2-[4-(3-methanesulfonyl-phenyl)-piperazin-1-yl]-ethanol] (described in GB 2027703) renders compounds which are inactive in the behavioral activity test; 3238±1089 cm/60 min (controls) to 3782±962 cm/60 min at 33 μmol/kg s.c., n=4, p>0.05, as well as in the neurochemical test; effects on 3,4-dihydroxyphenylacetic acid in the striatum; 1158±126 (controls) to 1239±162 ng/g tissue at 33 μmol/kg s.c., n=4, p>0.05.

      Synthesis
The synthesis of the present compounds is carried out by methods that are conventional for the synthesis of related known compounds. The syntheses of compounds in Formula 1, in general, comprise the reaction of an intermediate that supplies the alkyl group with an intermediate piperidine or piperazine that supplies the amine group of Formula 2:
Figure USRE046117-20160823-C00003
A convenient method of synthesis of the present compounds is by use of an alkyl iodide (e.g. 1-propyl-iodide). Alternatively, other leaving groups besides iodide may be used on the alkyl group, of course, such as sulfonates, particularly methanesulfonate or toluenesulfonate, bromo and the like. The alkyl intermediate is reacted with the appropriate amine in the presence of any convenient acid scavenger. The usual bases such as alkali metal or alkaline earth metal carbonates, bicarbonates and hydroxides are useful acid scavengers, as are some organic bases such as trialkylamines and trialkanolamines. The reaction medium for such reactions may be any convenient organic solvent which is inert to the basic conditions; acetonitrile, esters such as ethylacetate and the like and halogenated alkane solvents are useful. Usually the reactions will be carried out at elevated temperatures such as from ambient temperature to the reflux temperature of the reaction mixture, particularly from 50° C. to about 100° C.
Another convenient method of synthesis of the present compounds involves reductive amination with an amine of Formula 2:
Figure USRE046117-20160823-C00004
with an aldehyde or ketone, either in the presence of a reducing agent such as sodium cyanoborohydride or sodium triacetoxyborohydride or followed by reduction, e.g. using catalytic hydrogenation, to give a corresponding compound of Formula 1.

Figure USRE046117-20160823-C00006
with compounds of Formula 5:
Figure USRE046117-20160823-C00007
where Z is a leaving group like iodide. Other leaving groups besides iodide may be used on the alkyl group, of course, such as sulfonates, particularly methanesulfonate or toluenesulfonate, bromo and the like. The alkyl intermediate is reacted with the appropriate amine in the presence of any convenient acid scavenger. The usual bases such as alkali metal or alkaline earth metal carbonates, bicarbonates and hydroxides are useful acid scavengers, as are some organic bases such as trialkylamines and trialkanolamines. The reaction is performed in a suitable solvent such as n-butanol by heating at about 50-150° C.
Compounds of the Formula 1 wherein X═N is also accomplished by reacting compounds of Formula 6:
Figure USRE046117-20160823-C00008
with an aryl substituted with a leaving group of Formula 7:
Figure USRE046117-20160823-C00009
where Z is halide e.g. chloro, bromo, iodo, or sulfonate e. g. —OSO2CF3, or —OSO2F, in the presence of a base and a zerovalent transition metal catalyst such as Pd or Ni, according to known method (Tetrahedron Letters, vol 37, 1996, 4463-4466, J. Org. Chem., vol. 61, 1996, 1133-1135).
The catalyst, preferably Pd will have the ability to form ligand complex and undergo oxidative addition. Typical Pd catalysts will be Pd2(dba)3 (wherein dba refers to di-benzylidene acetone), Pd(PPh3)4, Pd(OAc)2, or PdCl2[P(o-tol)3]2 and typical phosphine ligands will be BINAP, P(o-tol)3, dppf, or the like. The usual bases such as alkali metal or alkaline earth metal carbonates, bicarbonates and alkyloxides are useful acid scavengers, as are some organic bases such as trialkylamines and trialkanolamines. The reaction medium for such reactions may be any convenient organic solvents, which are inert to the basic conditions; acetonitrile, toluene, dioxane, NMP (N-methyl-2-pyrrolidone), DME (dimethoxyethane), DMF (N,N-dimethylformamide), DMSO (dimethylsulfoxide) and THF (tetrahydrofuran) solvents are useful. Usually the reactions will be carried out at elevated temperatures such as from ambient temperature to the reflux temperature of the reaction mixture, particularly from 50° C. to about 120° C.
Compounds of the Formula 1 wherein X═N is also accomplished by reacting compounds of Formula 6 with an aryl substituted with a leaving group (e.g. F or Cl) via nucleophilic aromatic displacement reactions in the presence of a base as explained above.
Compounds of the Formula 1 wherein X═CH is also accomplished by transition metal catalyzed cross-coupling reaction, known as, for example, Suzuki and Stille reactions, to those skilled in the art.
The reaction may be carried out between compounds of Formula 8:
Figure USRE046117-20160823-C00010
wherein Y is, for example, a dialkylborane, dialkenylborane or boronic acid (e.g. BEt2, B(OH)2 (dotted lines can be double bonds)) or a trialkyltin (e.g. SnMe3, SnBu3), and an aryl substituted with a leaving group of Formula 7:
Figure USRE046117-20160823-C00011
(for definition of Z, see above) in the presence of a base and a zerovalent transition metal catalyst such as Pd or Ni, according to known methods (Chem. Pharm. Bull., vol 33, 1985, 4755-4763, J. Am. Chem. Soc., vol. 109, 1987, 5478-5486., Tetrahedron Lett., vol. 33, 1992, 2199-2202). In addition, Y can also be a zink- or magnesium-halide group (e.g. ZnCl2, ZnBr2, ZnI2, MgBr2, MgI2) according to known methods (Tetrahedron Lett., vol. 33, 1992, 5373-5374, Tetrahedron Lett., vol. 37, 1996, 5491-5494).
The catalyst, preferably Pd will have the ability to form ligand complex and undergo oxidative addition. The definition of ligands, bases and solvents, is mentioned above.
Alternatively, the transition metal catalyzed cross-coupling reaction can be performed with the opposite substitution pattern:
Figure USRE046117-20160823-C00012
with an heteroaryl/alkenyl substituted with an leaving group of Formula 10:
Figure USRE046117-20160823-C00013
in the presence of a base and a zerovalent transition metal catalyst such as Pd or Ni, according known methods discussed in the previous paragraph.
Compounds of Formula 11:
Figure USRE046117-20160823-C00014
can be prepared by catalytic hydrogenation of the tetrahydropyridine or pyridine from the previous paragraph, using standard methods known in the art, generally with palladium on carbon, PtO2, or Raney nickel as the catalyst. The reaction is performed in an inert solvent, such as ethanol or ethyl acetate, either with or without a protic acid, such as acetic acid or HCl. When the pyridine ring is quaternized with an alkyl group the ring can be partly reduced by NaBH4 or NaCNBH4, yielding the tetrahydropyridine analog which can further be reduced with catalytic hydrogenation.
Another convenient method of syntheses of compounds of the Formula 1, wherein X═CH is also accomplished by treating arylhalides of Formula 7:
Figure USRE046117-20160823-C00015
wherein Z is Cl, Br, or I, with alkyllithium reagents, for example, butyllithium, sec-butyllithium or tert-butyllithium, preferably butyllitium or Mg (grignard reaction) in an inert solvent. Suitable solvents include, for example ether or tetrahydrofuran, preferably tetrahydrofuran. Reaction temperatures range from about −110° C. to about 60° C. The intermediate lithium anions or magnesium anions thus formed may then be further reacted with a suitable electrophile of Formula 12:
Figure USRE046117-20160823-C00016
wherein A is defined as a protecting group like t-Boc (tert-butoxycarbonyl), Fmoc (fluorenylmethoxycarbonyl), Cbz (benzyloxycarbonyl) or a an alkylgroup like benzyl.
The intermediates of Formula 13:
Figure USRE046117-20160823-C00017
which are formed require that the hydroxy group be removed so as to result in compounds of Formula 1 (X═CH).
This step may be accomplished by one of several standard methods known in the art. For example, a thiocarbonyl derivative (for example a xanthate) may be prepared and removed by a free radical process, of which are known to those skilled in the art. Alternatively, the hydroxyl group may be removed by reduction with a hydride source such as triethylsilane under acidic conditions, using such as, for example, trifluoroacetic acid or boron trifluoride. The reduction reaction can be performed neat or in a solvent, such as methylene chloride. A further alternative would be to first convert the hydroxyl group to a suitable leaving group, such as tosylate or chloride, using standard methods. The leaving group is then removed with a nucleophilic hydride, such as, for example, lithium aluminium hydride. This last reaction is performed typically in an inert solvent, such as, ether or tetrahydrofuran.
Another alternative method for removing the hydroxyl group is to first dehydrate the alcohol to an olefin with a reagent such as Burgess salt (J. Org. Chem., vol 38, 1973, 26) followed by catalytic hydrogenation of the double bond under standard conditions with a catalyst such as palladium on carbon. The alcohol may also be dehydrated to the olefin by treatment with acid such as p-toluenesulfonic acid or trifluoroacetic acid.
The protecting group, A, is removed under standard conditions known by those skilled in the art. For example, t-Boc cleavages are conveniently carried out with trifluoroacetic acid either neat or in combination with methylene chloride. F-moc is conveniently cleaved off with simple bases such as, ammonia, piperidine, or morpholine, usually in polar solvents such as DMF and acetonitrile. When A is Cbz or benzyl, these are conveniently cleaved off under catalytic hydrogenation conditions. The benzyl group can also be cleaved off under N-dealkylation conditions such as treatment with α-chloroethyl chloroformate (J. Org. Chem., vol 49, 1984, 2081-2082).
It is further possible to convert a radical R1 in a compound of the Formula 1 into another radical R1, e.g. by oxidizing methylsulfide to methylsulfone (for example by m-chloroperoxybenzoic acid), substitution of a triflate or halide group with a cyano group (for example palladium catalyzed cyanation), substitution of triflate or halide group with a ketone (for example palladium catalyzed Heck reaction with butyl vinyl ether), substitution of a triflate or halide group with a carboxamide (for example, palladium catalyzed carbonylation), or cleaving an ether by, for example, converting a methoxy group into the corresponding hydroxyl derivate, which can further be converted into the corresponding mesylate or triflate. The terms mesylate andtriflate refers to OSO2CH3, CH3SO3 or OSO2CF3, CF3SO3, respectively.
In summary, the general process for preparing the present compounds has six main variations, which may briefly bedescribed as follows:

As used herein the term C1-C4 alkyl refers to an alkyl containing 1-4 carbon atoms in any isomeric form. The various carbon moieties are defined as follows: Alkyl refers to an aliphatic hydrocarbon radical and includes branched or unbranched forms such as methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, s-butyl, t-butyl. The term cycloalkyl refers to a radical of a saturated cyclic hydrocarbon such as cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl.
The term “patient” used herein refers to an individual in need of the treatment according to the invention.
The term “treatment” used herein relates to both treatment in order to cure or alleviate a disease or a condition, and to treatment in order to prevent the development of a disease or a condition. The treatment may either be performed in an acute or in a chronic way.
Both organic and inorganic acids can be employed to form non-toxic pharmaceutically acceptable acid addition salts of the compounds according to the invention. Illustrative acids are sulfuric, nitric, phosphoric, hydrochloric, citric, acetic, lactic, tartaric, palmoic, ethane disulfonic, sulfamic, succinic, cyclohexylsulfamic, fumaric, maleic, and benzoic acid. These salts are readily prepared by methods known in the art.
The pharmaceutical composition containing a compound according to the invention may also comprise substances used to facilitate the production of the pharmaceutical preparation or the administration of the preparations. Such substances are well known to people skilled in the art and may for example be pharmaceutically acceptable adjuvants, carriers and preservatives.
In clinical practice the compounds used according to the present invention will normally be administered orally, rectally, or by injection, in the form of pharmaceutical preparations comprising the active ingredient either as a free base or as a pharmaceutically acceptable non-toxic, acid addition salt, such as the hydrochloride, lactate, acetate, sulfamate salt, in association with a pharmaceutically acceptable carrier. The carrier may be a solid, semisolid or liquid preparation. Usually the active substance will constitute between 0.1 and 99% by weight of the preparation, more specifically between 0.5 and 20% by a weight for preparations intended for injection and between 0.2 and 50% by weight for preparations suitable for oral administration.
To produce pharmaceutical preparations containing the compound according to the invention in the form of dosage units for oral application, the selected compound may be mixed with a solid excipient, e.g. lactose, saccharose, sorbitol, mannitol, starches such as potato starch, corn starch or amylopectin, cellulose derivatives, a binder such as gelatine or polyvinyl-pyrrolidine, and a lubricant such as magnesium stearate, calcium stearate, polyethylene glycol, waxes, paraffin, and the like, and then compressed intotablets. If coated tablets are required, the cores, prepared as described above, may be coated with a concentrated sugar solution which may contain e.g. gum arabic, gelatine, talcum, titanium dioxide, and the like. Alternatively, the tablet can be coated with a polymer known to the man skilled in the art, dissolved in a readily volatile organic solvent or mixture of organic solvents. Dyestuffs may be added to these coatings in order to readily distinguish between tablets containing different active substances or different amounts of the active compound.
For the preparation of soft gelatine capsules, the active substance may be admixed with e.g. a vegetable oil or poly-ethylene glycol. Hard gelatine capsules may contain granules of the active substance using either the mentioned excipients for tablets e.g. lactose, saccharose, sorbitol, mannitol, starches (e.g. potato starch, corn starch or amylopectin), cellulose derivatives or gelatine. Also liquids or semisolids of the drug can be filled into hard gelatine capsules.
Dosage units for rectal application can be solutions or suspensions or can be prepared in the form of suppositories comprising the active substance in a mixture with a neutral fatty base, or gelatine rectal capsules comprising the active substance in admixture with vegetable oil or paraffin oil. Liquid preparations for oral application may be in the form of syrups or suspensions, for example solutions containing from about 0.2% to about 20% by weight of the active substance herein described, the balance being sugar and mixture of ethanol, water, glycerol and propylene glycol. Optionally such liquid preparations may contain coloring agents, flavoring agents, saccharine and carboxymethylcellulose as a thickening agent or other excipients known to the man in the art.
Solutions for parenteral applications by injection can be prepared in an aqueous solution of a water-soluble pharmaceutically acceptable salt of the active substance, preferably in a concentration of from 0.5% to about 10% by weight. These solutions may also containing stabilizing agents and/or buffering agents and may conveniently be provided in various dosage unit ampoules. The use and administration to a patient to be treated in the clinic would be readily apparent to an ordinary skill in the art.
In therapeutical treatment an effective amount or a therapeutic amount of the compounds according to the invention are from about 0.01 to about 500 mg/kg body weight daily, preferably 0.1-10 mg/kg body weight daily. The compounds may be administered in any suitable way, such as orally or parenterally. The daily dose will preferably be administered in individual dosages 1 to 4 times daily.
It is known for those skilled in the art that replacing a hydrogen in a non-substituted position in the aromatic ring with a fluorine atom may block the possibility for enzymatic hydroxylation which render the compound low oral bioavailability. This type of exchange (H to F) seldom changes the pharmacological profile. Thus, it may be important, in some cases to introduce a fluorine atom in any non-substituted positions in the aromatic ring of compounds of Formula 1 to improve the oral bioavailability.
The invention is further illustrated in the examples below, which in no way are intended to limit the scope of the invention.

The following tests were used for evaluation of the compounds according to the invention.
In Vivo Test: Behavior
For behavioral testing, the animals were placed in separate motility meter boxes 50×50×50 cm equipped with an array of 16×16 photocells (Digiscan activity monitor, RXYZM (16) TAO, Omnitech Electronics, USA), connected to an Omnitech Digiscan analyzer and a Apple Macintosh computer equipped with a digital interface board (NB DIO-24, National Instruments, USA). Behavioral data from each motility meter box, representing the position (center of gravity) of the animal at each time, were recorded at a sampling frequency of 25 Hz and collected using a custom written LABView™ application. The data from each recording session were analyzed with respect to distance traveled and small-scale movements, e.g. stops in the center of the behavior recording arena, during the recording session. To determine stops in the center, velocity at each time point is calculated as the distance traveled since the preceding sample divided by the time elapsed since the preceding sample. The number of stops is then calculated as the number of times that the velocity changes from a non-zero value to zero. The number of stops in the center of the behavioral recording arena is calculated as the number of stops occurring at a position at least ten centimeters from the edges of the recording arena. For behavioral testing of habituated rats, the animals were placed in the motility meter boxes 30 minutes before the administration of test compound. Each behavioral recording session lasted 6 or 30 minutes, starting immediately after the injection of test compound. Similar behavioral recording procedures was applied for non-habituated rats, habituated rats and drug pre-treated rats. Rats pre-treated with d-amphetamine are given the dose 1,5 mg/kg s.c. 5 min before the behavioral session in the motility meter. Rats pre-treated with dizolcipine (Mk-801) are given the dose 0,7 mg/kg i.p. 90 min before the behavioral session.in the motility meter.
In Vivo Test: Neurochemistry
After the behavioral activity sessions the rats were decapitated and their brains rapidly taken out and put on an ice-cold petri-dish. The limbic forebrain, the striatum, the frontal cortex and the remaining hemispheral parts of each rat were dissected and frozen. Each brain part was subsequently analyzed with respect to its content of monoamines and their metabolites. The monoaminergic indices analyzed were dopamine (DA), 3,4-dihydroxy-phenylacetic acid (DOPAC), homovanillic acid (HVA), 3-methoxytyramine (3-MT), serotonin (5-HT), 5-hydroxyindole acetic acid (5-HIAA), and noradrenaline (NA). All monoaminergic indices in the dissected tissue were analyzed by means of HPLC with electrochemical detection as described by Svensson K, et al., 1986, Naunyn-Schmiedeberg's Arch Pharmacol 334: 234-245 and references cited therein.
In Vivo Test: Pharmacokinetics in the Rat
To determine oral availability (F) and plasma half life (t½) of test compounds according to the invention experiments performed in the rat were undertaken. On day one rats were implanted with one catheter in the jugular vein and one catheter in the carotid artery under ketamine anesthesia. On day three test compound is injected either orally or in the jugular vein catheter. Blood samples are collected during 8 hours from the arterial catheter. The blood samples were heparinized and centrifuged. Plasma is collected from the centrifuged samples and frozen. The levels of test compound were subsequently determined in each sample by means of gas chromatography-mass spectrometry (Hewlett-Packard 5972MSD). The plasma samples, taken from the rats of the Sprague-Dawley strain, (0.5 ml) were diluted with water (0.5 ml), and 30 pmol (50 μl) of ((−)-S-3-(3-Ethylsulfonylphenyl)-N-n-propyl-piperidine as internal standard was added. The pH was adjusted to 11.0 by the addition of 25 μl saturated Na2CO3. After mixing, the samples were extracted with 4 ml dichloromethane by shaking for 20 min. The organic layer was, after centrifugation, transferred to a smaller tube and evaporated to dryness under a stream of nitrogen and subsequently redissolved in 40 μl toluene for GC-MS analysis. A standard curve over the range of 1-500 μmol was prepared by adding appropriate amounts of test compound to blank plasma samples. GC was performed on a HP-Ultra 2 capillary column (12 m×0.2 mm ID), and 2 μl was injected in the splitless mode. The GC temperature was held at 90° C. for 1 minute following injection, and was then increased by 30° C./min to the final temperature of 290° C. Each sample was run in duplicate. The lowest detectable concentration of test compound was generally found to be 1 pmol/ml.
