Definitions
- the invention relates to new 1 ⁇ .7 ⁇ -disubstituted spirolactones, processes for their preparation and pharmaceutical preparations containing them according to the claims.
- R 1 in formula I as an alkyl radical having 1 to 3 carbon atoms represents, for example, a methyl, ethyl, propyl or isopropyl group.
- 1 to 3 carbon atoms represents, for example, the formyl
- the new compounds of general formula I have the property of canceling or reversing the effect of aldosterone or deoxycorticosterone on the sodium and potassium salt excretion.
- the compounds according to the invention are therefore suitable for the treatment of certain forms of hypertension, of edema, for example in the case of heart failure, in liver cirrhosis and nephrotic syndrome, primary and secondary aldosteronism and other endocrinological disorders caused by aldosterone. They can also be used as diuretics.
- the active compounds according to the invention Compared to the commercially available spironolactone and its metabolites, which contain a mercapto or methylthio group instead of the acetylthio group in the 7 ⁇ position (Steroids 20 (1972) 41), the active compounds according to the invention have the advantage of higher activity and a prolonged duration of action, the effect also occurring is delayed.
- This activity profile indicates that the compounds according to the invention are biologically active compounds which are metabolic only in the organism be activated to so-called pro-drugs.
- such compounds have the advantage that the content of active substance in the blood plasma is less exposed to fluctuations.
- the compounds according to the invention are further characterized in that they are endocrinologically ineffective. You bind e.g. practically not at all on the androgen receptor.
- the compounds according to the invention which contain a thio group in both the 1 ⁇ and 7 ⁇ positions, have been shown to be superior to the known spironolactone in their antialdosterone activity in the test model by Hollmann (Naunyn-Schmiedebergs Arch. Exp. Path. Pharmak. 247 (1964) 419) and are distinguished from spironolactone by a later onset of action.
- the new active ingredients can be used in the same way as for spironolactone.
- the dosage of the active ingredients is below that of spironolactone. Due to the longer lasting effect, however, the new active ingredients usually only need to be applied once a day.
- the active ingredients can be processed into pharmaceutical preparations, preferably for enteral application, according to methods of galenics known per se.
- enteral application can be considered in particular tablets, coated tablets or capsules which contain about 25 to 200 mg of active ingredient per dose unit in an inert carrier material.
- the ⁇ 1.4.6 -unsaturated 3-ketopregnatriene of the formula II is expediently dissolved in a suitable protic solvent or in a mixture thereof, the desired thioalkanoic acid is added and warms the reaction mixture to temperatures above room temperature up to the boiling point of the solvent.
- suitable solvents or mixtures thereof are methanol, acetone and tetrahydrofuran.
- solubilizers such as diisopropyl ether, benzene and heptane do not disturb the course of the reaction.
- the starting material of the formula II is reacted with the corresponding alkyl mercaptan in a suitable solvent.
- suitable solvents are in particular organic bases such as pyridine, piperidine, collidine and lutidine.
- the reaction mixture can be warmed to temperatures above room temperature if extremely long reaction times are undesirable.
- alkali metal alcoholate e.g. Potassium methylate
- Any subsequent esterification of the mercapto group is carried out according to the steroid chemistry methods for the esterification of sterols.
- the esterification is preferably carried out with an activated derivative of a lower aliphatic carboxylic acid in the presence of pyridine and / or 4-dimethylaminopyridine.
- Suitable derivatives are, in particular, the anhydrides and halides of lower carboxylic acids, in particular acetic and propionic acids.
- reaction products according to the invention are separated off by methods known per se, such as precipitation, filtration or extraction, and are purified, for example, by chromatography and / or recrystallization.
- UV: ⁇ 236 16,000 (in methanol).
- Example 3a an ice-cooled solution of 6.0 g of 15 ⁇ .16ß-methylene-1 ⁇ .7 ⁇ -dimethylthio-3-oxo-17 ⁇ -pregn-4-en-21.17-carbolactone in 187 ml of ethanol is mixed with 2.27 g of potassium ethylate added and stirred for 45 minutes while cooling and passing argon. For working up, it is poured into ice water. The precipitate is filtered off, washed with water and dried.
- UV: ⁇ 236 11 600 (in methanol).

Abstract
Nouvelles spirolactones 1alpha.7alpha-dithio substituées de formule générale (I) dans laquelle R1 représente alkyl C1-3 et alcyl C1-3 et R2 représente l'hydrogène, alkyl C1-3 et acyl C1-3, leur préparation et leur utilisation comme médicament. Les composés possèdent une activité antialdostérone et présentent le profil d'activité d'un pro-médicament (''pro-drugs'').New substituted 1alpha.7alpha-dithio spirolactones of general formula (I) in which R1 represents alkyl C1-3 and alkyl C1-3 and R2 represents hydrogen, alkyl C1-3 and acyl C1-3, their preparation and their use as medication. The compounds possess antialdosterone activity and exhibit the activity profile of a pro-drug.
