and their physiologically acceptable salts and solvates.

Pyrimidine derivatives are known for example from EP 201 188 or WO 93/06104.

The invention was based on the task of finding new compounds with valuable properties, in particular those which can be used for the production of medicaments.

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

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

Quinazolines with 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 such as 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 ₅₀ values (concentration of the inhibitor which is required in order to achieve a 50% inhibition of the enzyme activity).

Enzymes isolated according to known methods can be used to carry out the determinations (e.g. W. J. Thompson et al., Biochem. 1971, 10, 311). A modified "batch" method by W.J. Thompson and M.M. Appleman (Biochem. 1979, 18, 5228) can be used.

The compounds are therefore suitable for the treatment of diseases of the cardiovascular system, in particular heart failure, and for the treatment and / or therapy of erectile dysfunction.

The use of substituted pyrazolopyrimidinones for the treatment of impotence is e.g. described in WO 94/28902.

The compounds are effective as inhibitors of phenylephrine-induced contractions in corpus cavemosum preparations from rabbits. This biological effect can e.g. can be detected by the method described by F. Holmquist et al. in J. Urol., 150, 1310-1315 (1993). The inhibition of the contraction shows the effectiveness of the compounds according to the invention for the therapy and / or treatment of erectile dysfunction.

The compounds of formula I can be used as active pharmaceutical ingredients in human and veterinary medicine. They can also be used as

Intermediates are used to manufacture other active pharmaceutical ingredients.

The compounds of the formula I and also the starting materials for their preparation are otherwise prepared by methods known per se, as described in the literature (for example in the standard works such as Houben-Weyl, methods of organic chemistry, Georg-Thieme-Verlag, Stuttgart) , are described, namely under reaction conditions which are known and suitable for the reactions mentioned. Use can also be made of variants which are known per se and are not mentioned here in detail.

In the compounds of the formulas II or III, X, Y, Z, R ⁹ , R ¹⁰ , R ¹¹ , r and the ring A, R ¹ , R ² , R ⁸ , Q and the ring C have the meanings given, in particular the given preferred meanings. If L is a reactive esterified OH group, this is preferably alkylsulfonyloxy with 1-6 C atoms (preferably methylsulfonyloxy) or arylsulfonyloxy with 6-10 C atoms (preferably phenyl- or p-tolylsulfonyloxy, also 2- naphthalenesulfonyloxy).

The compounds of the formula I can preferably be obtained by reacting compounds of the formula II with compounds of the formula III.

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

The starting compounds of the formula II and III are generally known.

If they are not known, they can be produced by methods known per se.

Compounds of the formula II can be obtained, for example, by reaction with POCI ₃ from the corresponding hydroxypyrimidines which are built up from thiophene derivatives and CN-substituted alkylene carboxylic acid esters (Eur. J. Med. Chem. 23, 453 (1988)).

The hydroxypyrimidines are prepared either by dehydration of corresponding tetrahydrobenzthienopyrimidine compounds or by the cyclization of 2-aminobenzthiophene-3-carboxylic acid derivatives with aldehydes or nitriles (e.g. Houben Weyl E9b / 2), which is customary for the preparation of pyrimidine derivatives.

In particular, the compounds of the formula II are reacted with the compounds of the formula III in the presence or absence of an inert solvent at temperatures between about -20 and about

150 °, preferably between 20 and 100 °.

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

Suitable inert solvents are e.g. Hydrocarbons such as hexane, petroleum ether, benzene, toluene or xylene; chlorinated hydrocarbons such as

Trichlorethylene, 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 or monoethyl ether (methyl glycol or ethyl glycol), ethylene glycol dimethyl ether (diglyme); Ketones such as acetone or butanone; Amides such as acetamide, dimethylacetamide, N-methylpyrrolidone or dimethylformamide (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 solvents mentioned.

It is also possible to convert one radical X into another radical X in a compound of formula I, e.g. by hydrolyzing an ester or a cyano group to a COOH group. Ester groups can e.g. can be saponified with NaOH or KOH in water, water-THF or water-dioxane at temperatures between 0 and 100 °.

Carboxylic acids can e.g. with thionyl chloride in the corresponding carboxylic acid chlorides and these are converted into carboxamides. By splitting off water in a known manner, carbonitriles are obtained from these.

An acid of the formula I can be converted into the associated acid addition salt using a base, for example by reacting equivalent amounts of the acid and the base in an inert solvent such as ethanol and subsequent evaporation. Bases that provide physiologically acceptable salts are particularly suitable for this implementation. So the acid of formula I with a base (eg sodium or potassium hydroxide or carbonate) in the corresponding metal, in particular Alkali metal or alkaline earth metal, or be converted into the corresponding ammonium salt.

Organic bases which provide physiologically acceptable salts, such as e.g. Ethanolamine.

On the other hand, a base of the formula I can be converted into the associated acid addition salt using an acid, for example by reacting equivalent amounts of the base and the acid in an inert solvent such as ethanol and subsequent evaporation. In particular, acids that provide physiologically acceptable salts are suitable for this implementation. So inorganic acids can be used, e.g. Sulfuric acid, nitric acid, hydrohalic acids such as hydrochloric acid or hydrobromic acid, phosphoric acids such as orthophosphoric acid, sulfamic acid, furthermore organic acids, especially aliphatic, alicyclic, araliphatic, aromatic or heterocyclic mono- or polybasic carboxylic, sulfonic or sulfuric acids, e.g. Formic acid, acetic acid, propionic acid, pivalic acid, diethyl acetic 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, ethanedisulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, naphthalene mono- and disulfonic acids, lauryl-sulfuric acid. Salts with physiologically unacceptable acids, e.g. Picrates can be used for the isolation and / or purification of the compounds of the formula I.

The invention furthermore relates to the use of the compounds of the formula I and / or their physiologically acceptable salts for the preparation of pharmaceutical preparations, in particular by a non-chemical route. Here, they can be brought into a suitable dosage form together with at least one solid, liquid and / or semi-liquid carrier or auxiliary and optionally in combination with one or more further active ingredients. The invention also relates to medicaments of the formula I and their physiologically acceptable salts as phosphodiesterase V inhibitors

The invention further relates to pharmaceutical preparations containing at least one compound of the formula I and / or one of its physiologically acceptable salts

These preparations can be used as pharmaceuticals in human or veterinary medicine. Suitable carrier substances are organic or inorganic substances which are suitable for enteral (for example oral), parenteral or topical application and do not react with the new compounds, for example water, vegetable oils, benzyl alcohols, alkylene glycols, polyethylene glycols, Glycenntπacetat, gelatin, carbohydrates such as lactose or starch, magnesium stearate, talc, Vaseline rectal application Suppositons, for parenteral application solutions, preferably oily or aqueous solutions, further suspensions, emulsions or implants, for topical application ointments, creams or powders The new compounds can also be lyophilized and the lyophilizates obtained can be used, for example, for the preparation of injection preparations The specified NEN preparations can be sterilized and / or contain auxiliaries such as lubricants, preservatives, stabilizers and / or wetting agents, emulsifiers, salts to influence the osmotic pressure, buffer substances, coloring, flavoring and / or several other active ingredients, for example a or more vitamins

The compounds of the formula I and their physiologically acceptable salts can be used in combating diseases in which an increase in the cGMP (cyclo-guanosine monophosphate) level leads to inhibition or prevention of inflammation and muscle relaxation

The invention also relates to the use of the compounds of the formula I and their physiologically acceptable salts and / or sol- vate for the manufacture of a medicament for the treatment of angina, high blood pressure, pulmonary hypertension, congestive heart failure, atherosclerosis, conditions of reduced patency of the cardiovascular system, peripheral vascular diseases, stroke, bronchitis, allergic asthma, chronic asthma, allergic rhinitis, glaucoma, irritable bowel syndrome , Tumors, renal failure, cirrhosis of the liver and for the treatment of male and female impotence.

The substances are generally preferably administered in doses between about 1 and 500 mg, in particular between 5 and 100 mg, per dosage unit. The daily dosage is preferably between about 0.02 and 10 mg / kg body weight. However, the specific dose for each patient depends on a variety of factors, for example on the effectiveness of the particular compound used, on the age, body weight, general health, sex, on the diet, on the time and route of administration, on the rate of elimination, combination of drugs and severity the respective disease to which the therapy applies. Oral application is preferred.

All temperatures above and below are given in ° C. In the examples below, "customary work-up" means: if necessary, water is added, if necessary, depending on the constitution of the end product, the pH is adjusted to between 2 and 10, extracted with ethyl acetate or dichloromethane, separated, dried organic phase over sodium sulfate, evaporates and purifies by chromatography on silica gel and / or by crystallization.
