TITLE

Antipsychotic Nitrogen-Containing Bicyclic Compounds

FIELD OF THE INVENTION

This invention relates to novel nitrogen-containing bicyclic compounds, pharmaceutical

compositions containing these compounds and methods of using these compounds to treat physiological or drug induced psychosis and as antidyskinetic agents.

BACKGROUND OF THE INVENTION

U.S. Patent No. 3,127,413 (Gray) discloses octahydroisoindoles of the formula:

wherein:

Ar represents a radical from an aromatic ring system which is monocyclic or bicyclic; Alk represents on alkylene chain, straight or branched, containing at least one and not more than three carbon atoms;

R is H or acyl; and

R' is lower-alkyl.

The octahydroisoindoles are useful as tranquilizing agents and for potentiating the action of

barbiturates.

Processes for preparing trisubstituted perhydro isoindolines of the following formula are described by Achini et al, Helvetica Chimica Acta, 57, Fasc. 3, pp. 572-585 (1974):

wherexn :

R¹ is H or COC₆H₅ ;

R² is NR⁴R⁵ , Br , OH , phenyl , or CN ;

R³ is H or OH; and

R⁴, R⁵ are H or lower alkyl.

German Patent 3721723 (Hoechst AG) describes substituted 6-Oxo-Decahydroisoquinolines of the formula:

wherein:

R¹ is benzyl, C₁-C₄ alkoxycarbonyl or 2,2,2- Trichloro-ethoxycarbonyl; and

R² is C₁-C₈ alkyl, C₂-C₈ alkenyl, cyclohexyl-C₁- C₄ alkyl, 9-fluorenyl, 1-Cyano-1- phenylmethyl or phenyl-C₁-C₄ alkyl.

These compounds are useful as tranquilizing agents.

U. S. Patent No. 3,689,492 (Schroeder et al.) discloses a compound having the formula:

This compound is useful as an analgesic in warm-blooded animals.

U. K. Patent No. 1,141,664 (Jansen)

discloses piperidine compounds having the

formula:

wherein Y is Ar or Ar³ and Z is Ar¹ or Ar², Ar being phenyl, halophenyl or lower alkoxy phenyl, Ar¹ being dihalophenyl, trihalophenyl, lower alkyl - halo- phenyl or trifluoromethy - halo -phenyl, Ar² being halophenyl and Ar³ being di -halo - phenyl or lower alkyl - halo - phenyl, with the proviso that when Y is Ar then Z is Ar¹, and when Y is Ar² then Z is Ar².

These compounds are useful as psychotropic and neuroleptic agents.

European Patent Application No. 0 196 132 (Kennis and Vandenberk) discloses compounds having the formula:

wherein X is O or S and Q is a radical of formula

or a radical of formula

These compounds are useful as antipsychotics. Janssen et al., Journal of Med. and Pharm.

Chem., vol. 1, 281-297 (1959), disclose compounds having the formula:

wherein L = H or F and R = H, F, C1, or CH3).

The authors discuss the CNS depressant properties of these compounds.

Compounds of the present invention demonstrate sigma receptor affinity. It is this sigma receptor affinity of the compounds of the present invention which makes them so advantageous over the compounds in the prior art. Traditionally, antipsychotic agents have been potent dopamine receptor

antagonists. For example, phenothiazines such as chlorpromazine and most butyrophenones such as haloperidol are potent dopamine receptor antagonists, These dopamine receptor antagonists are associated with a high incidence of side effects, particularly Parkinson-like motor effects or extra-pyramidal side- effects (EPS), and dyskinesias including tardive dyskinesias at high doses. Many of these side effects are not reversible even after the dopamine receptor antagonist agent is discontinued.

The present invention is related to

antipsychotic agents which are sigma receptor antagonists, not traditional dopamine receptor blockers known in the art, and therefore the

compounds of the present invention have low potential for the typical movement disorder side-effects associated with the traditional dopamine antagonist antipsychotic agents while they maintain the ability to antagonize aggressive behavior and antagonize hallucinogenic-induced behavior.

SUMMARY OF THE INVENTION

Compounds of this invention are novel

antagonists of sigma receptors, which may be useful for the treatment of physiological and drug-induced psychosis and dyskinesia.

Compounds of Formula (III) (Formula I where R² = OH) may be converted to compounds of Formula (IV), (Formula I where R² = O₂CR^2a) using an appropriate acylating agent, (R^2aCO) ₂O or R^2aCOCl. The acylation reaction may or may not employ a base. Bases which may be used for this reason include, but are not limited to, alkali metal hydrides, preferably sodium hydride, alkali metal carbonates, preferably

potassium carbonate, alkali metal dialkylamides, preferably lithium di-isopropylamide, alkali

bis (trialkyl-silyl) amides, preferably sodium

bis (trimethylsilyl) amide, alkyl alkali metal

compounds (such as n-butyl lithium), alkali metal alkoxides (such as sodium ethoxide), alkyl alkaline earth metal halides (such as methyl magnesium bromide), trialkylamines (such as triethylamine or di-isopropylethylamine) or polycyclic di-amines (such as, 1,4-diazabicyclo [2.2.2]octane or 1,8-diazabicyclo-[5.4.0]undecene). Alternatively, a dehydrating agent and a carboxylic acid of the

Formula, R^2aCO₂H, may be reacted with a compound of Formula III. Dehydrating agents include, but are not limited to, dialkyl or dicycloalkyl carbodiimides (such as dicyclohexyl-carbodiimide), an alkyl

chloroformate and a trialkylamine,

carbonyldiimidazole. Such dehydrating agents are known in the general literature (see J. March,

Advanced Organic Chemistry (New York: J. Wiley and Sons, 1985) pp. 348-351). Acylation procedures are also known in the general literature (see T. W.

Greene, Protective Groups in Organic Synthesis (New York: J. Wiley and Sons, 1981) pp 50-64. The

acylation procedures may use an inert solvent, compatible with the acylating agent or dehydrating agent as specified in the above March and Greene references or references cited therein. Inert solvents may include ethers such as tetrahydrofuran, halocarbons, such as dichloromethane, alkanes of 5 to 10 carbons, dialkylformamides of 3 to 10 carbons, dialkylacetamides of 4 to 16 carbons; cyclic tertiary amides such as N-methylpyrrolidone or aromatic amines such as pyridine.

Scheme II illustrates alternate methods to prepare some of the intermediates of Formula (II) . Amides of Formula (V) (where R²¹ is alkyl of 1 to 5 carbons, cycloalkyl of 3 to 6 carbons, cycloalkyl-alkyl of 4 to 7 carbons, phenyl-alkyl (1-5 carbons where the phenyl group is optionally substituted by R⁶ and R⁷, heteroaryl, naphthyl, heteroaryl-alkyl (1-5 carbons) or naphthyl-alkyl (1-5 carbons)) may be reacted with a reducing agent in the presence of an inert solvent to afford compounds of Formula (VI). Reducing agents may include, but are not limited to alkali metal aluminum hydrides, preferably lithium aluminum hydride, alkali metal trialkoxyaluminum hydrides (such as lithium tri-t-butoxyaluminum hydride), Scheme I I

hydrocarbons of 6 to 10 carbons. Reaction

temperatures for the reduction range from about

-100°C to 200°C, preferably -80°C to 80°C. The choice of reducing agent and solvent is known to those skilled in the art as taught in the above cited March reference (pp 1093-1110). Compounds of Formula (VI) then may be treated with an oxidizing agent in an inert solvent to generate compounds of Formula II (where R¹ = CH₂ R²¹). Oxidizing agents may include transition metal oxides, such as CrO₃ or MnO₂ , pyridine-chromium complexes, such as CrO₃•C₅H₅N, pyridinium dichromate or pyridinium chlorochromate, an oxalyl chloride-dimethyl sulfoxide-triethylamine reagent system, commonly called the Swern oxidation system (D. Swern et al., J. Organic Chem., 43, 2480-2482 (1978)) or a dimethyl sulfoxide-dicyclohexyl-carbodiimide system (see H. O. House, Modern

Synthetic Reactions (New York: W. A. Benjamin Inc., 1972), pp. 416-421). Such oxidations may employ an inert solvent such as those in the reduction step described above or halocarbons of 1 to 6 carbons, preferably dichloromethane or 1,2-dichloroethane.

Alternatively, compounds of Formula V may be reacted with a reducing agent in an inert solvent to produce compounds of Formula VII, Reducing agents include alkali metal borohydrides, preferable sodium or lithium borohydride and alkali metal

trialkoxyaluminum hydrides (such as lithium tri-t-butoxyaluminum hydride). Inert solvents include those used in the conversion of compounds of Formula V to those of Formula (VI) as well as hydroxy-alkanes of 2 to 6 carbons. Compounds of Formula (VII) may then be converted by the reduction-oxidation sequence described above for the conversion of compounds

Scheme III

of Formula (V) to those of Formula (II) via

intermediates of Formula (VI).

Intermediates of Formula (V) may be prepared according to the following references or by a

combination of the general procedures described therein: R. L. Augustine, J. Organic Chem. 23, 1853- 1856 (1958); S. Durand-Henchoz, R. C. Moreau, Bull. Soc. Chim. Francais, (11), 3416-3422 (1966).

Some of the compounds of Formula (I) may be also be prepared according to Scheme III. Compounds of Formula (VIII) (Formula I where R¹ = CH₂Ph) may be reacted with a reducing agent in an inert solvent to give compounds of Formula IX (Formula (I) where R¹ = H). Reducing agents may include molecular hydrogen and a noble metal catalyst, preferably palladium-on-carbon or platinum (IV) oxide, an ammonium formate-noble metal catalyst system (such as ammonium

formate-palladium-on-carbon) (S. Ram, L. D. Spicer) Tetrahedron Lett., 280(5), 515-516 (1987)) or an alkali metal and liquid ammonia (preferably sodium and liquid ammonia) (see the above Green reference, pp 272-274). Inert solvents may include but are not limited to, lower alkyl alcohols, ethereal solvents such as diethyl ether or tetrahydrofuran or aromatic or non-aromatic hydrocarbons of 6 to 10 carbons.

Intermediates of Formula (IX) may then be reacted with a compound, R¹X where X may be Cl, Br, I, alkylsulfonyloxy (preferably methanesulfonyloxy), or haloalkylsulfonyloxy groups (preferably

trifluoromethylsulfonyloxy), to generate compounds of Formula (I). A base may be required to effect the transformation from (IX) to (I). Bases may include alkali metal carbonates (such as potassium carbonate, trialkylamines, alkali metal hydrides (such as sodium hydride or quarternary ammonium salts (such as Triton B). The choice of solvent must be compatible with the base employed; solvents may include lower alkyl alcohols, ethereal solvents, lower alkyl nitriles or aromatic or non-aromatic hydrocarbons of 6 to 10 carbons. For a summary of the general procedures which may be employed, see the above March reference (pp 364-381).

Scheme IV

Some of the compounds of Formula (I) may be prepared according to Scheme IV. Compounds of Formula (VI) may be reacted with compounds of Formula R^3aχ, where X may be defined as it was for R¹X above in the conversion of compounds of Formula (VIII) to those of Formula (I). Similarly bases and inert solvents may be employed as they were in the conversion of (IX) to (I) .

Some of the compounds of Formula I may also be prepared according to Scheme V. Compounds of Formula (VII) may be reacted with a sulfonylating agent,

R²⁰SO₂Cl or (R²⁰SO₂)₂O. (where R²⁰ is lower alkyl, substituted phenyl or lower haloalkyl), preferably methanesulfonylchloride, p-toluenesulfonyl chloride or trifluoro methanesulfonic anhydride, in the presence of a base, such as a trialkylamine,

preferably triethylamine, an alkali metal hydride, preferably sodium hydride, an aromatic amine, preferably pyridine, or an alkali metal carbonate or alkoxide. Such a sulfonylation may be performed in an inert solvent such as a halocarbon of 1 to 6 carbons, preferably dichloromethane, ethereal solvents, such as diethyl ether or tetrahydrofuran, aromatic or non-aromatic hydrocarbons of 6 to 10 carbons or lower alkanenitriles, preferably

acetonitrile. The sulfonylated intermediates of Formula (XI) are reacted with compounds of Formula R^3aγH where Y = O or S. A base and an appropriate solvent may be used and may be drawn from the lists of bases and solvents described above for the

transformation of (VI) to (X) above. Finally, compounds of Formula (XII) may be reacted with a reducing agent in an inert solvent to give compounds of Formula XIII (Formula I where R² = H, R¹ = CH₂R²¹, R³ = R.^3aγ, and Y = O, S. The choice of reducing agent follows that described above for the conversion of Compounds of Formula (V) to those of Formula (VI).

Utilities Section

The compounds of this invention and their pharmaceutically acceptable salts possess psychotropic properties, particularly antipsychotic activity of good duration with selective sigma receptor antagonist activities while lacking the typical movement disorder side-effects of standard dopamine receptor antagonist antipsychotic agents. These compounds may also be useful as antidotes for certain psychotomimetic agents such as phencyclidine (PCP), and as antidyskinetic agents.

In vitro

Sigma Receptor Binding Assay

Male Hartley guinea pigs (250-300 g, Charles

River) were sacrificed by decapitation. Brain

membranes were prepared by the method of Tarn (Proc.

Natl. Acad. Sci. USA 80: 6703-6707, 1983). Whole brains were homogenized (20 seconds) in 10 vol

(wt/vol) of ice-cold 0.34 M sucrose with a Brinkmann Polytron (setting 8). The homogenate was centrifuged at 920 × g for 10 minutes. The supernatant was

centrifuged at 47,000 × g for 20 minutes. The

resulting membrane pellet was resuspended in 10 vol (original wt/vol) of 50 mM Tris HCl (pH 7.4) and incubated at 37°C for 45 minutes to degrade and dissociate bound endogenous ligands. The membranes were then centrifuged at 47,000 × g for 20 minutes and resuspended in 50 mM Tris HCl (50 mL per brain).

0.5 mL aliquots of the membrane preparation were incubated with unlabeled drugs, 1 nM (+)-[³H]SKF 10,047 in 50 mM Tris HCl, pH 7.4, in a final volume of 1 mL. Nonspecific binding was measured in the presence of 10 μM (+)-SKF 10,047. The apparent dissociation constant (Kd) for (+)-[³H]SKF 10,047 is 50 nM. After 45 minutes of incubation at room temperature, samples were filtered rapidly through Whatman GF/C glass filters under negative pressure, and washed 3 times with ice-cold Tris buffer (5 mL). IC₅₀S were calculated from log-logit pious.

Apparent K_is were calculated from the equation, K_i = IC₅₀/[1 + (L/K_d)] (4), where L is the concentration of radioligand and K_d is its dissociation constant. Data are shown in Table A. Dopamine Receptor Binding

Membranes were prepared from guinea pig striatum by the method described for sigma receptor binding. The membranes were then resuspended in 50 mM Tris HCl (9 mL per brain).

0.5 mL aliquots of the membrane preparation were incubated with unlabeled drugs, and 0.15 nM

[³H] spiperone in a final volume of 1 mL containing 50 mM Tris HCl, 120 mM NaCl and 1 mM MgCl₂ (pH 7.7).

Nonspecific binding was measured in the presence of 100 nM (+) -butaclamol. After 15 minutes of incubation at 37°C, samples were filtered rapidly through Whatman GF/C glass filters under negative pressure, and washed three times with ice-cold binding buffer (5 mL).

IC₅₀S were calculated from log-logit plots.

Apparent K_is were calculated from the equation

K_i=IC₅₀ [1+ (L/K_d)] (4), where L is the concentration of radioligand and K_d is its dissociation constant. Data are shown in Table A.

The examples of this invention shown in Table A indicate potent binding affinity for sigma receptors.

Therefore these compounds are not expected to produce the extrapyramidal symptoms that are typical of that produced by haloperidol and other typical

antipsychotics that are dopamine receptor antagonists. Tab l e A

Isolat ion- Induced Aggr ession, in Mice

This is a modification of the method of Yen et al. (Arch. Int. Pharmacodyn. 123: 179-185, 1959) and Jannsen et al. (J. Pharmacol. Exp. Ther. 129: 471-475, 1960). Male Balb/c mice (Charles River) were used. After 2 weeks of isolation in plastic cages (11.5 × 5.75 × 6 in) the mice were selected for aggression by placing a normal group-housed mouse in the cage with the isolate for a maximum of 3 minutes . Isolated mice failing to consistently attack an intruder were eliminated from the colony.

Drug testing was carried out by treating the isolated mice with test drugs or standards. Fifteen minutes after dosing with test drugs by the oral route, one isolated mouse was removed from its home cage and placed in the home cage of another isolate. Scoring was a yes or no response for each pair. A maximum of 3 minutes was allowed for an attack and the pair was separated immediately upon an attack.

Selection of home cage and intruder mice was

randomized for each test. Mice were treated and tested twice a week with at least a 2 day washout period between treatments. Treatments are shown in Table B. Tab le B

Induction of Catalepsy

This is a modification of the method of Costall and Naylor (Psychopharmacologia (Berl.), 43, 69-74, 1975). Male CD rats (Charles River) weighing 250-300 g were treated with test drugs and standards by the oral route and tested for the presence of catalepsy 30 minute, 60 minute, and 90 minute after treatment. To test for catalepsy, each rat is placed with its front paws over a 10 cm high horizontal bar. The intensity of catalepsy is measured by the length of time it takes the animal to move both forelegs to the table. A time of 20 seconds is considered maximal catalepsy. Results are shown in Table C. Table C

Dosaσe Forms

Daily dosage ranges from 1 mg to 2000 mg .

Dosage forms (compositions) suitable for

administration ordinarily will contain 0.5-95% by weight of the active ingredient based on the total weight of the composition.

The active ingredient can be administered orally in solid dosage forms, such as capsules, tablets, and powders, or in liquid dosage forms, such as elixirs, syrups, and suspensions; it can also be administered parenterally in sterile liquid dosage forms.

Gelatin capsules contain the active ingredient and powdered carriers, such as lactose, sucrose, mannitol, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar

diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any

unpleasant taste and protect the tablet from the atmosphere, or enteric-coated for selective

disintegration in the gastrointestinal tract.

Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance.

In general, water, a suitable oil, saline, aqueous dextrose (glucose), and related sugar

solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents. Also used are citric acid and its salts and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl- or propyl-paraben, and chlorobutanol.

Suitable pharmaceutical carriers are described in Remington's Pharmaceutical Sciences, A. Osol, a standard reference text in this field.
