Description
The present invention relates to a 3-amino-. propoxy-2-methyl-indole derivative.
British patent specification No. 1'-35G'31O 5 discloses and claims a class of 3-aminopropoxy~indole derivatives having a blocking effect on the adrenergic p-receptors.
The present invention provides 4-(2-benzoyloxy-3-tert butylaminopropoxy)-2-methyl-indole of formula I, -la43798 - 2 not specifically described in British patent specification No. l'356'31O which has now been found to have more benefi cial effects than would have been expected for such a compound, i.e. exceptionally good tolerability and parti5 cularly high and long lasting activity having regard to the generality of the compounds specifically disclosed and claimed in British patent specification No. 1'356*310.
The present invention also provides a process for the production of the compound of formula I as defined above, which comprises esterifying the compound of formula II, The present process may for example be effected in conventional manner as described in the Example and in our copending application No. 1791/76 (patent specification No. 43797) for analogous compounds.
The compound of formula II is known.
The compound of formula I can, by virtue of the asymmetric carbon atom in the position p to the oxygen atom bound to the indole nucleus, exist in the form of optically active isomers or as a racemate.
The process of the invention does not alter the configuration of the asymmetrically substituted carbon atom. Accordingly, when a racemic starting material is employed, a racemic final product of formula I is ob25 tained, and when an optically active starting material is employed^corresponding optically active final product - 3 is obtained.
The resulting compound of formula I may be isolated and purified using conventional techniques.
The free base form of the compound of formula I 5 may be converted Into acid addition salt forms and vice-versa in conventional manner.
In the following non-limitative Example , all temperatures are indicated in degrees Centigrade and are uncorrected.
EXAMPLE; 4- (2-benzoyloxy~3-tert.butylamlnopropoxy)26 g of henzoic acid are dissolved, while heating, in 50 cc of hexamethylphosphoric acid triamide and 3.5 g of l-tert.butylamino-3-(2-methyl-indole-4yloxy)-2-propanol are added. After cooling, 3.0 g of benzoic acid anhydride are added and stirring is effected for 20 hours at room temperature. The resulting clear, yellow solution is poured onto ice, 0.5 litres of ether are added and stirring is effected for 2 hours. After making the liquid alkaline with concentrated ammonia, the ether phase le separated, shaken out with tartaric acid, made alkaline with caustic soda solution while cooling with ice and extracted with methylene chloride. After evaporating the solvent, the residue is crystallised with 1 mol of fumaric acid from methanol and acetone. M.p. of hydrogen fumarate form: 189-191°.
In analogous manner, but employing appropriate, optically active starting material in approximately equivalent amounts, the compound of formula I can be obtained in (S) form (M.P. of the hydrogen malonate 95°) and in (R) form (M.P. of the hydrogen malonate 95°) .
The compound of formula I exhibits pharmacological activity. In particular, the compound exhibits a blocking effect on the adrenergic p receptors (a p-blocking effect) as indicated in standard tests, for example, by an inhibition of the positive inotropic - 5 adrenaline effect in the spontaneously beating guineapig atrium and by an inhibition of the tachycardia and hypotension induced by isoproterenol in anaesthetized cats in the infusion test.
Additionally, the compound exhibits an antiarrhythmic affect as indicated in standard tests, for example, as demonstrated in mice according to the method of Lawson, J.W., J. Pharmac. Exp. Ther. 160 (1968) 22-31.
Furthermore, the compound of formula I inhibits lipolysis induced by isoproterenol as indicated by standard tests. For example, in vitro, the inhibition of lipolysis can be observed in isolated fat cells-taken from the epidymal fat tissue of rats, the cells having been isolated in accordance with the method of M. Rodbell [J.Biol, Chem. 239 (1964} 375-380].
In addition, the compound inhibits isoproterenol-induced glycogenolysis as indicated by standard tests, for example by an inhibition of glycogenolysis stimulated by isoproterenol in vivo in rats.
The compound is therefore indicated for use as a p-blocking agent. Such agents are indicated for use inter alia in the prophylaxis and therapy of coronary diseases, especially in the treatment of Angina pectoris, in the treatment of the hyperkinetic heart syndrome and the conditions resulting from a muscular hypertrophic subvalvular aortic stenosis. - 6 An indicated daily dose is from about 1 to 10 mg; it may be administered in divided doses 2 to 4 times a day in unit dosage form containing from about 0.25 to about 5 mg, or in sustained release form.
The (S)-enantiomer of the compound of formula I and acid salt forms thereof are more active than the corresponding (R)-enantiomers, and accordingly the compound is preferably in racemic Or S enantiomeric form.
The compound of formula 1 may be administered in pharmaceutically acceptable acid addition salt form. Such acid addition salt forms exhibit the Game order of activity as the free base form and are readily prepared in conventional manner. Representative acid addi15 tion salt forms include the fumarate, hydrogen fumarate and hydrogen malonate.
The present invention also provides a pharmaceutical composition comprising the compound of formula X, in free base form or in pharmaceutically acceptable acid addition salt form, in association with a pharmaceutically acceptable diluent or carrier. Such compositions may be in the form of, for example, a solution or a capsule.
