Definitions
- the present invention relates, as new products to [(phenyl-4-piperazinyl-1) -2 ethoxy] -3 p-cymene and its ortho meta derivatives, para monosubstituted or disubstituted on the phenyl nucleus, a process for the preparation of these derivatives; it also relates to medicaments containing, as active principle, at least one of said compounds.
- R 1 , R 2 identical or different, being chosen from a hydrogen atom, a halogen atom or a hydroxyl radical, alkyl having from 1 to 4 carbon atoms, alkoxy having from 1 to 5 carbon atoms, phenoxy , benzyloxy, trifluoromethyl, acetyl.
- the alkyl or alkoxy groups may be straight or branched chain groups.
- alkyl group having from 1 to 5 carbon atoms is for example a methyl, ethyl, propyl, isopropyl, butyl, sec-butyl or tert-butyl group, preferably methyl.
- An alkoxy group having from 1 to 5 carbon atoms is for example a methoxy, ethoxy, propoxy, isopropoxy, butoxy, isobutoxy, neopentoxy, pentoxy, isopentoxy group, preferably ethoxy or is
- a halogen atom is preferably an atom of chlorine.
- the products according to the invention can also be in the form of the salts of the products of formula (I) with a pharmaceutically acceptable, mineral acid such as for example hydrochloric acid or sulfuric or organic acid such as for example citric acid, tartaric, malic, maleic, fumaric, or sulphonic methane.
- p-cymene is substituted only at 3 by an alkoxy. It is therefore a derivative of thymol and therefore the compound is original.
- the products of the invention are made from (2-chloroethoxy) 3-p-cymene of formula (II) and (substituted phenyl) -1 piperazine of formula (III) according to the following general reaction scheme:
- R 1 and R 2 being defined above.
- the number of moles of compound (III) is approximately double the number of moles of compound (II).
- the pharmaceutically acceptable salts for example hydrochlorides, are obtained in a known manner by bringing a solution of the product of formula (I) into contact with the acid in question (for example by bubbling hydrochloric acid in a solution of the product of formula (I)).
- these salts may contain one or two moles of salifying acid per mole of product of formula (I).
- the present invention also relates to the medicaments characterized in that they contain, as active product, at least one product of formula (I); said drugs can be useful especially in the field of urology.

- reaction medium After cooling to room temperature, the reaction medium is poured onto a 10% sodium bicarbonate solution. The aqueous phase obtained is extracted twice with 100 ml of methylene chloride. The combined organic phases are washed with water saturated with sodium chloride. We dry them then on sodium sulfate. After filtration, the solvent is removed under vacuum. 38.40 g of crude product are obtained.
- Said crystals have a melting point F of 190-192 ° C, IR and NMR spectra in accordance with the proposed structure, an AgNO titer of 99.6%.

- Acute toxicity in mice a) Principle The products were administered orally at a single dose in mice. After a 14-day observation period, mortality was recorded.
- the stimulation of postsynaptic alpha-adrenergic receptors by norepinephrine causes the isolated vas deferens to contract.
- the concentration of product is sought in the presence of which the concentration of norepinephrine must be multiplied by two to obtain the same effect as in the absence of said product.
- the concentration of product is sought in the presence of which the contracting effect of a given concentration of norepinephrine is halved, compared to the contraction induced before the addition of said product.
- noradrenaline 0.4 mg. Kg -1
- the prior administration of a substance with an alpha-blocking property makes it possible to reduce this toxicity.
- ED 50 effective dose 50
- Neighboring molecules have already been described. They had blocking properties of the ⁇ -1 and ⁇ -adrenergic receptors in the heart and, therefore, had antihypertensive properties.
- the molecules of the present invention also have blocking properties of the ⁇ -1 receptors but they are especially active at the level of the lower urinary tract and only retain a weak residual action at the cardiac level.
- the products in accordance with the present invention therefore have very advantageous pharmacological properties and their toxicity is sufficiently low to allow their use in therapy.
- the products of the invention can therefore be used in human or veterinary medicine, in particular in the treatment of dysurias linked to uretral hypertonia.
- the products can be administered by the general route (parenteral, oral, rectal) or by topical route.
- the pharmaceutical compositions containing, as active ingredient, at least one product according to the invention in combination with a pharmaceutically acceptable vehicle can be solid or liquid and can be presented, for example, in the form of injectable preparations, tablets, capsules, granules.
- the dosage can vary within wide limits, in particular according to the type and severity of the condition to be treated and according to the mode of administration.
- Such pharmaceutical compositions constitute an object of the invention. Their preparation process is another.
- the invention relates to the use of the compounds of formula (I) for the preparation of medicaments useful for the treatment of dysurias linked to uretral hypertonia.
