The compounds of the formula (I) obtained can, if they contain suitable basic functions, be converted, in particular for pharmaceutical applications, into their physiologically acceptable salts with inorganic or organic acids.

Moreover, the novel compounds of the formula (I) can, if they contain carboxylic acid functions, be converted, if desired, into their addition salts with inorganic or organic bases, in particular for pharmaceutical applications into their physiologically acceptable addition salts. Bases suitable for this purpose are, for example, sodium hydroxide, potassium hydroxide, ammonia, cyclohexylamine, dicyclohexylamine, ethanolamine, diethanolamine and triethanolamine.
The present invention relates to racemates if the compounds of the formula (I) have only one element of chirality. However, the application also embraces the individual diastereomeric pairs of enantiomers or mixtures thereof which are present when more than one element of chirality is present in the compounds of the formula (I), and the individual optically active enantiomers which constitute the racemates mentioned.
The subject matter of the present invention also embraces the compounds according to the invention and their salts in which one or more hydrogen atoms are replaced by deuterium.
The novel compounds of the formula (I) and their physiologically acceptable salts have useful pharmacological properties. They are bradykinin-B1 antagonists.
For example, the compounds
CHO cells expressing the hBK1 receptor are cultivated in Dulbecco's modified medium. The medium from confluent cultures is removed and the cells are washed with PBS buffer, scraped off and isolated by centrifugation. The cells are then homogenized in suspension and the homogenate is centrifuged and resuspended. The protein content is determined and the membrane preparation obtained in this manner is then frozen at −80° C.
After thawing, 200 μl of the homogenate (50 to 100 μg of proteins/assay) are incubated at room temperature with 0.5 to 1.0 nM of kallidin (DesArg10, Leu9), [3,4-prolyl-3,43H(N)] and increasing concentrations of the test substance in a total volume of 250 μl for 60 minutes. The incubation is terminated by rapid filtration through GF/B glass fibre filters which had been pretreated with polyethyleneimine (0.3%). The protein-bound radioactivity is measured in a TopCount NXT. Non-specific binding is defined as radioactivity bound in the presence of 1.0 μM of kallidin (DesArg10, Leu9), [3,4-prolyl-3,43H(N)]. The concentration/binding curve is analysed using a computer-assisted nonlinear curve fitting. The Ki which corresponds to the test substance is determined using the data obtained in this manner.
In the test described, substances A to E have the following Ki values:
By virtue of their pharmacological properties, the novel compounds and their physiologically acceptable salts are suitable for treating diseases and symptoms of diseases caused at least to some extent by stimulation of bradykinin-B1 receptors. The compounds according to the invention can be used in methods which serve to alleviate or treat pain, where a therapeutically effective amount of the compound according to the invention is administered to a patient. Thus, they are suitable, for example, for treating patients having chronic pain, neuropathic pain, postoperative pain, inflammatory pain, perioperative pain, migraine, arthralgia, neuropathies, nerve injuries, diabetic neuropathy, neurodegeneration, neurotic skin diseases, stroke, irritable bladder, irritable colon, respiratory disorders, such as asthma or chronic obstructive lung disease, irritations of the skin, the eyes or the mucosa, duodenum ulcers and stomach ulcers, stomach inflammation or other inflammatory disorders, pain caused by osteoarthritis or back pain, and also pain associated with another aetiology.
For treating pain, it may be advantageous to combine the compounds according to the invention with stimulating substances such as caffeine or other pain-alleviating active compounds. If active compounds suitable for treating the cause of the pain are available, these can be combined with the compounds according to the invention. If, independently of the pain treatment, other medical treatments are also indicated, for example for high blood pressure or diabetes, the active compounds required can be combined with the compounds according to the invention.
The dosage necessary for obtaining a pain-alleviating effect is, in the case of intravenous administration, expediently from 0.01 to 3 mg/kg of body weight, preferably from 0.1 to 1 mg/kg, and, in the case of oral administration, from 0.1 to 8 mg/kg of body weight, preferably from 0.5 to 3 mg/kg, in each case 1 to 3 times per day. The compounds prepared according to the invention can be administered intravenously, subcutaneously, intramuscularly, intrarectally, intranasally, by inhalation, transdermally or orally, aerosol formulations being particularly suitable for inhalation. They can be incorporated into customary pharmaceutical preparations, such as tablets, coated tablets, capsules, powders, suspensions, solutions, metered aerosols or suppositories, if appropriate together with one or more customary inert carriers and/or diluents, for example with maize starch, lactose, cane sugar, microcrystalline cellulose, magnesium stearate, polyvinylpyrrolidone, citric acid, tartaric acid, water, water/ethanol, water/glycerol, water/sorbitol, water/polyethylene glycol, propylene glycol, cetylstearyl alcohol, carboxymethylcellulose or fatty substances, such as hardened fat, or suitable mixtures thereof.
