Description

The invention relates to compounds of the formula I ##STR2## in which R.sup.1, R.sup.2 in each case independently of one another are H, A, OA, alkenyl, alkinyl, NO.sub.2, CF.sub.3 or Hal, where one of the radicals R.sup.1 or R .sup.2 is always .noteq.H,

R.sup.1 and R.sup.2 together are also alkylene having 3-5 C atoms, R.sup.3, R.sup.4 in each case independently of one another are H, A, OA, Hal, NO.sub.2, NH.sub.2, NHA or NAA', R.sup.3 and R.sup.4 together are also --O--CH.sub.2 --CH.sub.2 --, --O--CH.sub.2 --O or --O--CH.sub.2 --CH.sub.2 --O--, A, A' in each case independently of one another are alkyl having 1 to 6 C atoms, X is an unsaturated 5-7-membered heterocycle having 1-4 N, O and/or S atoms which is unsubstitued or mono-, di- or trisubstituted by A, Hal or CF.sub.3 and in which additionally further CH.sub.2 groups can be replaced by NH, NA, S or O bonded via N or C, Hal is F, Cl, Br or I and n is 0, 1, 2 or 3, and the physiologically acceptable salts thereof.

Pyrimidine derivatives are disclosed, for example, in EP 201 188 or in WO 93/06104.

The invention was based on the object of finding novel compounds which have valuable properties, in particular those which can be used for the preparation of pharmaceuticals.

It has been found that the compounds of the formula I and their salts have very valuable pharmacological properties combined with good tolerance.

In particular, they show specific inhibition of cGMP phosphodiesterase (PDE V).

Quinazolines which have cGMP phosphodiesterase-inhibitory activity are described, for example, in J. Med. Chem. 36, 3765 (1993) and ibid. 37, 2106 (1994).

The biological activity of the compounds of the formula I can be determined by methods as they are described, for example, in Wo 93/06104. The affinity of the compounds according to the invention for cGMP and cAMP phosphodiesterase is determined by determining their IC.sub.50 values (concentration of inhibitor required for achieving a 50% inhibition of enzyme activity). To carry out the determinations, enzymes which have been isolated by customary methods may be used (for example W. J. Thompson et al., Biochem. 1971, 10, 311). To carry out the experiments, a modified batch method of W. J. Thompson and M. M. Appleman (Biochem. 1979, 18, 5228) may be used.

Thus, the compounds are suitable for treating diseases of the cardiovascular system, in particular cardiac insufficiency, and for the therapy of impaired potency.

The compounds of the formula I can be employed as pharmaceutically active ingredients in human and veterinary medicine. Furthermore, they can be employed as intermediates for the preparation of other pharmaceutically active ingredients.

Accordingly, the invention relates to the compounds of the formula I and to a process for the preparation

Besides, the compounds of the formula I and also the starting materials for their preparation are prepared by methods known per se and they are described in the literature (for example in the standard publications such as Houben-Weyl, Methoden der organischen Chemie [Methods in Organic Chemistry], Georg-Thieme-Verlag, Stuttgart), under reaction conditions which are known and suitable for the abovementioned reactions. It is also possible to make use of variants which are known per se and not mentioned in greater detail in the present text.

In the compounds of the formulae II, III and IV, R.sup.1, R.sup.2, R.sup.3, R.sup.4, X and n have the abovementioned meanings, in particular the abovementioned preferred meanings.

If L is a reactive esterified OH group, then this is by preference alkylsulfonyloxy having 1-6 C atoms (preferably methylsulfonyloxy) or arylsulfonyloxy having 6-10 C atoms (preferably phenyl- or p-tolyl-sulfonyloxy, furthermore also 2-naphthalenesulfonyloxy).

If desired, the starting materials may also be formed in situ, so that they are not isolated from the reaction mixture but immediately reacted further to give the compounds of the formula I. On the other hand, it is possible to carry out the reaction stepwise.

The compounds of the formula I in which X is bonded to the thienopyrimidine ring system via N can be obtained by preference by reacting compounds of the formula II with an unsaturated 5-7-membered heterocycle which has at least one NH group and which is unsubstituted or mono-, di- or trisubstituted by A, Hal or CF.sub.3 and in which additionally further CH.sub.2 groups can be replaced by NH, NA, S or O.

Some of the starting materials of the formula II are known. If they are not known, they can be prepared by methods known per se.

Precursors of the compounds of the formula II can be prepared for example by cyclization and halogenation analogously to the procedure described in J. Med. Chem. 24, 374 (1981). Subsequent reaction with arylalkylamines gives the compounds of the formula II.

In detail, the reaction of the compounds of the formula II with the NH-containing heterocycle is carried out in the presence or absence of an inert solvent at temperatures between approximately -20 and approximately 150.degree., preferably between 20 and 100.degree..

Addition of an acid-binding agent, for example an alkali metal hydroxide, alkali metal carbonate, alkali metal bicarbonate, alkaline earth metal hydroxide, alkaline earth metal carbonate or alkaline earth metal bicarbonate, or of another salt of a weak acid of the alkali metal or alkaline earth metals, preferably of potassium, sodium or calcium, or an addition of an organic base such as triethylamine, dimethylamine or pyridine or quinoline or of an excess of the amine component may be advantageous.

Examples of suitable inert solvents are hydrocarbons such as hexane, petroleum ether, benzene, toluene or xylene; chlorinated hydrocarbons such as trichloroethylene, 1,2-dichloroethane, carbon tetrachloride, chloroform or dichloromethane; alcohols such as methanol, ethanol, isopropanol, n-propanol, n-butanol or tert-butanol; ethers such as diethyl ether, diisopropyl ether, tetrahydrofuran (THF) or dioxane; glycol ethers such as ethylene glycol monomethyl ether, ethylene glycol monoethyl ether (methylglycol or ethylglycol) or ethylene glycol dimethyl ether (diglyme); ketones such as acetone or butanone; amides such as acetamide, dimethylacetamide or dimethyl-formamide (DMF); nitriles such as acetonitrile; sulfoxides such as dimethyl sulfoxide (DMSO); nitro compounds such as nitromethane or nitrobenzene; esters such as ethyl acetate, or mixtures of the abovementioned solvents.

Compounds of the formula I in which X is bonded to the thienopyrimidine ring system via C can furthermore be obtained by reacting compounds of the formula III with compounds of the formula IV. As a rule, the starting compounds of the formulae IV and V are known. If they are not known, they can be prepared by methods known per se.

Compounds of the formula III can be obtained for example by means of reaction with POCl.sub.3, starting from compounds which are synthesized from thiophene derivatives and CN-substituted heterocycles (Eur. J. Med. Chem. 23, 453 (1988).

The reaction of the compounds of the formula III with compounds of the formula IV is carried out under similar conditions regarding reaction time, temperature and solvent as has been described for the reaction of the compounds of the formula II with NH-containing heterocycles.

It is furthermore possible to convert a radical R.sup.3 and/or R.sup.4 in a compound of the formula I into a different radical R.sup.3 and/or R.sup.4, for example by reducing the nitro groups to amino groups (for example by hydrogenation on Raney nickel or Pd/charcoal in an inert solvent such as methanol or ethanol) or to hydrolyze cyano groups to give COOH groups.

Furthermore, free amino groups can be acylated in the customary manner with an acid chloride or acid anhydride or free amino groups alkylated in the customary manner with an unsubstituted or substituted alkyl halide, expediently in an inert solvent such as dichloromethane or THF and/or in the presence of a base such as triethylamine or pyridine at temperatures between -60 and +30.degree..

A base of the formula I may be converted with an acid to give the corresponding acid addition salt, for example by reacting equivalent amounts of the base and of the acid in an inert solvent such as ethanol, followed by evaporation. Particularly suitable acids for this reaction are those which give physiologically acceptable salts. Thus, it is possible to use inorganic acids, for example sulfuric acid, nitric acid, hydrohalic acids such as hydrochloric acid or hydrobromic acid, phosphorus acids such as orthophosphoric acid, sulfamic acid, furthermore organic acids, in particular aliphatic, alicyclic, araliphatic, aromatic or heterocyclic mono- or polybasic carboxylic, sulfonic or sulfuric acids, e.g. formic acid, acetic acid, propionic acid, pivalic acid, diethylacetic acid, malonic acid, succinic acid, pimelic acid, fumaric acid, maleic acid, lactic acid, tartaric acid, malic acid, citric acid, gluconic acid, ascorbic acid, nicotinic acid, isonicotinic acid, methane- or ethanesulfonic acid, ethanedi-sulfonic acid, 2-hydroxyethanesulfonic acid, benzene-sulfonic acid, p-toluenesulfonic acid, naphthalenemono- and -disulfonic acids, laurylsulfuric acid. Salts with acids which are physiologically not acceptable, e.g. picrates, can be used for isolating and/or purifying the compounds of the formula I.

On the other hand, the free bases of the formula I may, if desired, be liberated from their salts by using bases (e.g. sodium hydroxide, sodium carbonate, potassum hydroxide or potassium carbonate).

The invention further relates to the use of the compounds of the formula I and/or their physiologically acceptable salts for the preparation of pharmaceutical products, in particular by non-chemical routes. They can be brought into a suitable pharmaceutical form together with at least one solid, liquid and/or semi-liquid excipient or auxiliary and, if appropriate, in combination with one or more other active ingredients.

The invention also relates to pharmaceuticals of the formula I and to their physiologically acceptable salts as phosphodiesterase V inhibitors.

The invention furthermore relates to pharmaceutical products comprising at least one compound of the formula I and/or a physiologically acceptable salt thereof.

These products can be used as pharmaceuticals in human or veterinary medicine. Suitable excipients are organic or inorganic substances which are suitable for enteral (e.g. oral), parenteral or topical adminstration and which do not react with the novel compounds, for example water, vegetable oils, benzyl alcohols, alkylene glycols, polyethylene glycols, glycerol triacetate, gelatin, carbohydrates such as lactose or starch, magnesium stearate, talc, petroleum jelly. Forms which are used for oral administration are, in particular, tablets, pills, sugar-coated tablets, capsules, powders, granules, syrups, liquids or drops, forms for rectal administration are, in particular suppositories, forms for parenteral administration are, in particular, solvents, preferably oily or aqueous solutions, furthermore suspensions, emulsions or implants, and forms for topical administration are ointments, creams or powders. The novel compounds may also be lyophilized and the resulting lyophilisates used for example for the preparation of injectable products. The abovementioned products can be in sterilized form and/or comprise auxiliaries such as glidants, preservatives, stabilizers and/or wetting agents, emulsifiers, salts for modifying the osmotic pressure, buffer substances, colourings, flavourings and/or other active ingredients, e.g. one or more vitamins.

The compounds of the formula I and their physiologically acceptable salts can be employed for combating diseases in which a raised cGMP (cyclo-guanosine monophosphate) level leads to the inhibition or prevention of inflammations and to muscular relaxation. The compounds according to the invention can be used especially in the treatment of diseases of the cardiovascular system and for the therapy of impaired potency.
