Abstract

The invention concerns the use of active principles having an activity antagonist of the substance P, capable of passing through the hematoencephalic barrier, for preparing a medicine for the treatment of diskinesia linked with diseases of the central nervous system.

Description

USE OF ANTAGONISTS OF SUBSTANCE P FOR THE TREATMENT OF LATE DYSKINESIA

The present invention relates to the application of active principles endowed with an antagonistic activity of substance P and capable of crossing the blood-brain barrier, for the preparation of a medicament intended for the treatment of dyskines and related to diseases of the nervous system central and in particular late dyskinesias.

Dyskinesias are a syndrome that results in impaired movement such as involuntary movements of the limbs, tongue, lips or neck [Baldessarim, The Pharmacological bas s 10 of Therapeutics, 8th edition (1990), section 3 [Drugs and the Treatment of Psychiatry Disorders], Chap 18, 383-435, Goodman and Gilman's, Pergamon press].

The causes of dyskinesias in humans are many and diverse. An example is that of dyskinesias due to the use of most of the neuroleptic drugs which appear neurological side effects which have been described in more detail by Baldessarim et al., Ara. J. Psychiatry, 137, 1163-1172 (1980) and by Latimer, Can. J. Psychiatry 40, 2suppl, 49S-54S (1995).

Among these side effects, tardive dyskmesis is a syndrome which appears after prolonged treatment, of several months or several years, by neuroleptics and which results in impaired movements. These effects disappear by re-administration of the neuroleptic agent. There is currently no other form of treatment for these conditions.

25 Substance P antagonists are described for their activity in many conditions, including central nervous system conditions, but these active substances have never been shown to have an effect on the treatment of disease-related dyskinesias of the central nervous system and nothing

30 could suggest. It has now been found, and this is the subject of the present invention, that substance P antagonists which cross the blood brain barrier are capable of treating dyskinesias linked to diseases of the central nervous system.

The present invention relates to the application of these products to the preparation of a medicament intended for the treatment of these conditions as well as to the compositions which contain these active principles.

Among the antagonists of substance P which cross the blood-brain barrier may be mentioned by way of example the products of the class of derivatives of 1,2-diamino ethane or of 1-acylamino-2-amino ethane, receptor antagonists. non-peptidic tachykinins, of the perhydroisoindole class, of the 3-amino-quinuclidin-2-substituted class, of the 2,3-disubstituted piperidin class, of the 3-amino-piperidin-2-substituted class , from the class of trisubstituted morpholine derivatives, from the class of substituted aromatic derivatives, from the class of quaternary salts of substituted piperidines, or of quaternary basic amides.

More particularly, among the products of the class of derivatives of 1,2-diamino ethane or 1-acylamino-2 amino-2 ethane, antagonists of substance P (non-tachykinin receptor antagonists), mention may be made of those of formula general:

Among the antagonists of substance P, the following products may in particular be mentioned: LY303870, CP122721, CP96345, CP122999, CP99994, FK888, GR205171, GR203040, L709210, L733060, L736281, L732138, L737488, L740141, L740141, L740147 , CGP49823, SR140333.

The activity of substance P antagonists, which cross the blood-brain barrier, in the treatment of dyskinesias has been demonstrated in the model of dyskinesias induced by haloperidol in rats:

PRINCIPLE:

The model of dyskinesias induced by haloperidol (a classic neuroleptic) is characterized by involuntary movements of the mouth, face, tongue known as "Vacuous Chew g Movement" (VCM) [J0ergensen et al. Psychopharma- cology, 116: 89-92 (1994); Waddmgton Psychopharmacology, 101: 431-447 (1990)].

The decanoate form of haloperidol is capable of inducing in rats from the 4th week after infection, a large number of buccolinguinal movements (very similar to dyskinetic movements occurring in humans following chronic administration of neuroleptics).

TECHNICAL:

Maize Sprague-Dawley rats weighing 200-220 g are kept for at least 5 days before use. The rats are grouped in groups of 3, with free access to food and water. In the morning of the experience, food and water are removed for the duration of the experience.

40 mg / kg of haloperidol decanoate (0.8 ml / kg) are injected into the animals by intramuscular route to induce orofacial dyskinesia. (Jorgensen et al., Psychopharmacol., 116, 89 (1994). The control animals receive an equivalent volume of vehicle used for haloperidol.

6 weeks after the injection of haloperidol decanoate, the animals receive the substance P antagonist, mtra-peritoneally, or its excipient. Dyskinetic behavior characterized by abnormal involuntary buccolingual movements is measured by counting the number of chews during 2 periods of 30 minutes of observation each: one preceding the administration of the molecule to be tested and the other 30 minutes after the administration of this molecule. The measurements are compared. An active product is a product which significantly reduces the number of involuntary movements evaluated after its administration compared to the number of involuntary movements evaluated before its administration.

RESULTS:

The following products have been studied: Product 1: [imino-1 (2-methoxyphenyl) -2 ethyl] -2 diphenyl-7,7 perhydroisoindolone-4- (3aR, 7aR):

Product 2: {(R) -1 - [N- (2-methoxybenzyl) acetylamino] -3- (1H-indol-3- yl) -2- [N- (2- (4- (piperidin-1 -yl ) piperidin-1 -yl) acetylamino] -propane}

Product 3: (2S, 3S) -3- (2-methoxy-5-trifluoromethoxybenzyl) -amino-2-phenyl-piperidine dihydrochloride:

N H, 2HC1

V Table I

At doses of 10 to 30 mg / kg i.p. the products studied inhibit from 47 to 69% of abnormal oral chewing movements.

The present invention also relates to the preparation of pharmaceutical compositions comprising a substance P antagonist capable of crossing the blood-brain barrier, in the pure state or in the form of a combination with one or more compatible and pharmaceutically acceptable diluents and / or adjuvants and / or optionally in combination with any other physiologically active pharmaceutically compatible product, intended for the treatment of dyskinesias linked to diseases of the central nervous system.

The compositions prepared according to the invention can be used parenterally, orally, rectally, transdermally and aerosols.

The sterile compositions for parenteral administration which can in particular be used in the form of infusions are preferably aqueous or non-aqueous solutions, suspensions or emulsions. As solvent or vehicle, it is possible to use water, propylene glycol, a polyethylene glycol, vegetable oils, in particular olive oil, injectable organic esters, for example ethyl oleate or the like. suitable organic solvents. These compositions can also contain adjuvants, in particular wetting, isotonizing, emulsifying, dispersing and stabilizing agents. Sterilization can be done in several ways, by for example by aseptic filtration, by incorporating sterilizing agents into the composition, by irradiation or by heating. They can also be prepared in the form of sterile solid compositions which can be dissolved at the time of use in a sterile injectable medium.

The compositions for rectal administration are suppositories or rectal capsules, which contain, in addition to the active product, excipients such as cocoa butter, semi-synthetic glycerides or polyethylene glycols.

The solid compositions for oral administration can be capsules, tablets, pills, powders or granules. In these compositions, the active principle (optionally associated with another pharmaceutically compatible product) is mixed with one or more inert diluents or adjuvants, such as sucrose, lactose or starch. These compositions can also include substances other than diluents, for example a lubricant such as magnesium stearate.

The liquid compositions for oral administration can be pharmaceutically acceptable emulsions, solutions, suspensions, syrups and elixirs containing inert diluents such as water or paraffin oil. These compositions can also include substances other than diluents, for example wetting, sweetening or flavoring products.

The compositions for topical administration can be, for example, creams, ointments, or lotions.

The compositions can also be aerosols. For use in the form of liquid aerosols, the compositions can be stable sterile solutions or solid compositions dissolved at the time of use in sterile pyrogen-free water, serum or any other pharmaceutically acceptable vehicle. For the use in the form of dry aerosols intended to be directly inhaled, the active principle is is finely divided and associated with a diluent or vehicle water-soluble liquid with a particle size of 30 to 80 μm, for example dextran, mannitol or lactose.

In general, the doctor will determine the dosage he considers most appropriate based on age, weight and all other factors specific to the subject to be treated. The doses depend on the desired effect and on the duration of the treatment. For an adult, they are generally between 0.25 and 2500 mg per day in staggered doses.

The following example, given without limitation, illustrates a composition prepared according to the invention and intended for the treatment of dyskinesias.

Example

Active product tablets having the following composition are prepared according to the usual technique:

- [imino-1 (2-methoxyphenyl) -2 ethyl] - .. diphenyl-7,7 perhydroisoindolone-4- (3aR, 7aR) 25 mg

- starch 83 mg

- silica 30 mg

- magnesium stearate 3 mg
