The present invention relates to a novel use of antagonists of the central cannabinoid receptors or so-called CB1 receptors.
More particularly, the invention relates to the use of CB1 receptor antagonists for the preparation of drugs useful in the treatment of appetency disorders. The purpose of drugs useful in the treatment of appetency disorders is to regulate consumption desires, particularly desires to consume sugars, carbohydrates, alcohol or drugs and more generally to consume appetizing ingredients.
In the present description and in the claims, appetency disorders are understood as meaning:
- disorders associated with a substance and especially abuse of a substance
and/or dependency on a substance,
- disorders of food behaviors, especially those liable to cause excess weight,
irrespective of its origin, for example bulimia, appetency for sugars and non-
insulin-dependent diabetes.
Substances are understood as meaning appetizing ingredients such as sugars, carbohydrates, alcohols or drugs.
The present invention therefore further relates to the use of a CBj receptor antagonist for the preparation of drugs useful in the treatment of bulimia and obesity, including obesity associated with type n diabetes (non-insulin-dependent diabetes), or more generally any disease resulting in the patient becoming overweight, and in the treatment of drug abuse or drug dependency.
Delta-9-tetrahydrocannabinol, or A9-THC, is the main active constituent extracted from Cannabis sativa (Tuner, 1985; in Marijuana, 84,'Ed. Harvey, DY, IRL Press, Oxford).
The effects of cannabinoids are due to an interaction with high affinity specific receptors coupled to G proteins. Two types of receptors are currently described: the CB1 receptors, which are present predominantly in the central nervous system (Devane et al., Molecular Pharmacology, 1988, 34, 605 - 613), and the CB2 receptors, which are present in the immune system (Nye et al., The Journal of Pharmacology and Experimental Therapeutics, 1985, 234. 784 - 791; Kaminski et al., 1992, Molecular Pharmacology, 42, 736 - 742; Munro et al., Nature, 1993, 365, 61 - 65). Characterization of these receptors has been made possible by the development of synthetic ligands such as CP 55,940 (J. Pharmacol. Exp. Ther., 1988, 247, 1046 - 1051) and WIN 55212-2 (J. Pharmacol. Exp. Ther., 1993, 264. 1352 - 1363) and, more recently, by the discovery of the selective CB1 receptor
antagonist SR 141716 A (M. Rinaldi-Carmona et al., FEBBS Lett., 1994, 350. 240 -244).
Families of compounds having an affinity for the cannabinoid receptors have been described in several patents or patent applications, especially European patent application EP-576 357, which describes pyrazole derivatives, and patent application WO 96/02248, which describes especially benzofuran derivatives.
More particularly, N-piperidino-5-(4-chlorophenyl)- l-(2,4-dichlorophenyl)-4-methylpyrazole-3-carboxamide, also called SR 141716, of the formula
(Formula Removed)
its pharmaceutically acceptable salts and their solvates are described in European patent application EP-656 354 as CB1 central receptor antagonists.
SR 141716 A is the hydrochloride of SR 141716.
It is known that delta-9-tetrahydrocannabinol, whose international non-proprietary name is dronabinol, is used in the treatment of anorexia, especially in patients suffering from AIDS (J. Pain Symptom Manage., 1995, 10 (2), 89 - 97) or cancer (J. Palliat. Care, 1994,10 (1), 14 - 18).
It is further described that SR 141716 and its salts, which are central cannabinoid receptor antagonists, can be used in the treatment of appetite disorders, especially as anorexigenic agents, and in the treatment of disorders associated with the use of psychotropic substances.
Conventional anorexigenic agents cause an appetite reduction which is generally independent of the foods to be consumed.
Surprisingly, it has now been found that CB1 receptor antagonists have a specific property by acting electively on consumption behavior disorders pertaining to appetizing substances.
Thus the administration of a CBi receptor antagonist makes it possible to regulate the desire to consume non-essential food items such as excess sugars,
excess carbohydrates, alcohol or drugs.
In fact, animal tests have revealed a novel behavior: the animal no longer shows spontaneous appetency for the ingredient, for example sugar or alcohol, which it normally finds pleasurable. This lack of appetency also manifests itself when the animal has been pretreated with a neuropeptide known to increase the appetite, for example neuropeptide Y (NPY).
According to one of its aspects, the present invention relates to the use of a CB1 receptor antagonist for the preparation of drugs useful in the treatment of appetency disorders.
The CB1 receptor antagonists appropriate for the purposes of the invention are particularly the compounds of the formula
(Formula Removed)
in which:
- RI is hydrogen, a fluorine, a hydroxyl, a (C1-C5)alkoxy, a (C1-C5)alkylthio, a
hydroxy(C1-C5)alkoxy, a group -NR10R11, a cyano, a (C1-C5)alkylsulfonyl or a
(C1-C5)alkylsulfmyl;
- R2 and R3 are a (C1-C4)alkyl or, together with the nitrogen atom to which they are
bonded, form a saturated or unsaturated 5- to 10-membered heterocyclic radical
which is unsubstituted or monosubstituted or polysubstituted by a (C1-C3)alkyl or
by a (C1-C3)alkoxy;
- R4, R5, R6, R7, Rg and R9 are each independently hydrogen, a halogen or a
trifluoromethyl, and if RI is a fluorine, R4, R5, Re, R?, Rg and/or Rg can also be a
fluoromethyl, with the proviso that at least one of the substituents R4 or R; is
other than hydrogen; and
- R10 and RH are each independently hydrogen or a (C1-C5)alkyl, or RIO and Rn,
together with the nitrogen atom to which they are bonded, form a heterocyclic
radical selected from pyrrolidin-1-yl, piperidin-1-yl, morpholin-4-yl and
piperazin-1-yl, which is unsubstituted or substituted by a and their salts and their solvates.
More particularly, the present invention relates to the use of N-piperidino-5-(4-chlorophenyl)-1 -(2,4-dichlorophenyl)-4-methylpyrazole-3-carboxamide, its pharmaceutically acceptable salts and their solvates for the preparation of drugs useful in the treatment of appetency disorders.
According to the present invention, the CB1 receptor antagonists can also be used in association with another active principle for the preparation of drugs useful in the treatment of appetency disorders, especially in the treatment of disorders of food behaviors; it is possible to use a pharmaceutical composition comprising a CB1 receptor antagonist in association with a compound for regulating metabolic disorders, especially a Ps-adrenergic receptor agonist, hereafter called a PS agonist.
Thus the present invention further relates to pharmaceutical compositions containing a CB1 receptor antagonist and a regulator of metabolic disorders, for example a hypolipemic, hypolydemic or lipolytic. More particularly, the present invention relates to pharmaceutical compositions containing a CB1 receptor antagonist and a ß3 agonist.

In the pharmaceutical compositions of the present invention for oral, sublingual, subcutaneous, intramuscular, intravenous, transdermal, local or rectal administration, the active principle, by itself or in association with another active principle, can be administered to animals and humans in unit forms of administration mixed with conventional pharmaceutical carriers. The appropriate unit forms of administration include oral forms such as tablets, gelatin capsules, powders, granules and solutions or suspensions to be taken orally, sublingual and buccal forms of administration, aerosols, implants, subcutaneous, intramuscular, intravenous, intranasal or intraocular forms of administration and rectal forms of administration.
In the pharmaceutical compositions of the present invention, the active principle or active principles are generally formulated in dosage units. The dosage unit contains from 0.5 to 1000 mg, advantageously from 1 to 500 mg and preferably from 2 to 200 mg of CB1 receptor antagonist per dosage unit for daily administration.
In cases where 2 active principles are associated, the dosage unit contains from 0.5 to 600mg,advantageously from 1 to 400 mg and preferably from 2 to 200 mg of CB1 receptor antagonist compound and from 0.5 to 600 mg, advantageously from 2 to 400 mg and preferably from 10 to 250 mg of the other active principle, especially a ß3 agonist.
When a solid composition is prepared in the form of tablets, a wetting agent such as sodium laurylsulfate can be added to the micronized or non-micronized active principle(s) and the whole is mixed with a pharmaceutical vehicle such as silica, starch, lactose, magnesium stearate, talcum or the like. The tablets can be coated with sucrose, a variety of polymers or other appropriate substances, or else they can be treated so as to have a sustained or delayed activity and so as to release a predetermined amount of active principle continuously.
A preparation in the form of gelatin capsules is obtained by mixing the active principle or active principles with a diluent, such as a glycol or a glycerol ester, and incorporating the resulting mixture into soft or hard gelatin capsules.
A preparation in the form of a syrup or elixir can contain the active
principle or active principles together with a sweetener, which is preferably calorie-free, methylparaben and propylparaben as antiseptics, a flavoring and an appropriate color.
The water-dispersible powders or granules can contain the active principle or active principles mixed with dispersants or wetting agents or with suspending agents such as polyvinylpyrrolidone or polyvidone, as well as with sweeteners or taste correctors.
Rectal administration is effected using suppositories, which are prepared with binders melting at the rectal temperature, for example cocoa butter or polyethylene glycols.
Parenteral administration is effected using aqueous suspensions, isotonic saline solutions or injectable sterile solutions containing pharmacologically compatible dispersants and/or solubilizing agents, for example propylene glycol or butylene glycol.
Thus, to prepare an aqueous solution for intravenous injection, it is possible to use a cosolvent, for example an alcohol such as ethanol or a glycol such as polyethylene glycol or propylene glycol, and a hydrophilic surfactant such as Tween® 80. To prepare an oily solution for intramuscular injection, the active principle can be solubilized with a triglyceride or a glycerol ester.
Transdermal administration can be effected using patches in multilaminar form or with a reservoir in which the active principle is in alcoholic solution.
The active principle or active principles can also be formulated as microcapsules or microspheres, optionally with one or more carriers or additives.
The active principle or active principles can also be presented in the form of complexes with a cyclodextrin, for example a-, P- or y-cyclodextrin, 2-hydroxy-propyl-p-cyclodextrin or methyl-ß-cyclodextrin.
Among the sustained release forms useful in the case of chronic treatments, it is possible to use implants. These can be prepared in the form of an oily suspension or in the form of a suspension of microspheres in an isotonic medium.
According to another aspect of the invention, the CBj receptor antagonist and the regulator of metabolic disorders, especially the Pa agonist, can be administered simultaneously, sequentially or over a period of time in the treatment of appetency disorders, especially in the treatment of disorders of food behaviors.
The invention therefore further relates to a kit for the treatment of
appetency disorders by the administration, simultaneously, sequentially or over a period of time, of a CB1 receptor antagonist and a regulator of metabolic disorders, especially a ß3 agonist, in which kit said CB1 receptor antagonist and said regulator of metabolic disorders, especially said 3 agonist, are in separate compartments and optionally in different packagings.
More particularly, said kit contains N-piperidino-5-(4-chlorophenyl)-l-(2,4-dichlorophenyl)-4-methylpyrazole-3-carboxamide, one of its pharmaceutically acceptable salts or one of their solvates, and N-[(2S)-7-ethoxycarbonylmethoxy-l,2,3,4-tetrahydronaphth-2-yl]-(2R)-2-(3-chlorophenyl)-2-hydroxyethanamine or one of its pharmaceutically acceptable salts.
According to another of its aspects, the invention further relates to a method of treating appetency disorders, especially a method of treating disorders of food behaviors, which consists in administering, to a subject in need thereof, a (therapeutically) effective amount of a CB1 receptor antagonist as defined above. Said CB1 receptor antagonist can advantageously be used in association with a regulator of metabolic disorders, especially a ß3 agonist, as defined above. In particular, the CB1 receptor antagonist and the regulator of metabolic disorders can be administered simultaneously, sequentially or over a period of time.
TEST No. 1: Effect of SR 141716 A on the intake of a sucrose solution in rats
The experiment is performed according to W.C. Lynch et al., Physiol. Behav., 1993,54,877-880.
Male Sprague-Dawley rats weighing 190 to 210 g are under a normal light cycle (from 7 am to 7 pm) and receive water and food ad libitum.
For 6 days, between 11 am and 3 pm, the food and the water bottles are withdrawn and the rats are given a 5% sucrose solution to drink.
Rats drinking less than 3 g of sucrose solution are eliminated.
On the seventh day the test is carried out according to the following procedure:
9 am: withdrawal of food,
10 am: oral administration of SR 141716 A,
11 am = TO: introduction of bottles containing a weighed sucrose solution, TO + 1 hour, TO + 2 hours, TO + 3 hours, TO + 4 hours: measurement of the sucrose consumption by weighing of the bottles.
TABLE 1
(Table Removed)
* p < 0.05; ** p < 0.01, Dunnett test
It is seen from the results reported in TABLE 1 that the administration of SR 141716 A very considerably reduces the consumption of aqueous sugar solution at or above a dose of 0.3 mg/kg.
TEST No. 2: Effect of SR 141716 A on the consumption of an alcohol solution in mice
Male C 57 BL 6 mice (Iffa-Credo) are isolated on the day of their arrival in an animal housing under a reverse cycle (night from 10 am to 10 pm) with 2 bottles filled with water. After 1 week, one of the bottles of water is replaced with a bottle filled with a 10% alcohol solution for 6 hours of the test. Each day, 30 minutes before the bottle of alcohol is introduced, the mice are treated subcutaneously with SR 141716 A. The amounts of alcohol and water consumed are measured after 6 hours. The test is repeated for 4 days.
TABLE 2
(Table Removed)
**p< 0 l,D.0unnett test
The results show that the alcohol consumption decreases very substantially for the treated animals: from 1.9 + 0.1 g for an untreated animal to 1.0 + 0.2 g for an animal receiving 3 mg/kg of SR 141716 A; the water consumption increased in parallel: from 1.1 ± 0.1 to 1.6 ± 0.3 g.
