Definitions
- the invention relates to new aralkyldiamine derivatives, processes for their preparation and medicaments containing these compounds.
- Class I compounds such as, for example, flecainide (INN) (N- (2-piperidylmethyl) -2,5-bis (2,2,2-trifluoroethoxy) benzamide), lidocaine (INN) (2-diethylamino-2 ' , 6'-acetoxylidide) and propafenone (INN) (2 '- [2-hydroxy-3- (propylamino) propoxy] -3-phenylpr ⁇ piophenon), act locally on the nerve and myocardial membranes and thereby slow the conduction of stimuli, which in turn reduces the forwarding of premature heartbeats. In addition, the tendency of damaged cells to send out premature heartbeats is suppressed.
- the class II compounds are the so-called ⁇ -blockers.
- Propranolol (INN) (1-isopropylamino-3- (1-naphthyloxy) -2-propanol) may be mentioned here as an example.
- Class III compounds such as amiodarone (INN) (2-butyl-3-benzofuranyl) - [4- (2-diethylaminoethoxy) -3,5-diiodophenyl] ketone) or sotalol (INN) (4 '- (l-Hydroxy-2-isopropylaminoethyl) methanesulfonanidide) have little or no influence on the conduction of the stimulus. In fact, they are largely independent of the stimulus conduction. These connections extend the duration of the action potential of the heart muscle and thereby lengthen the time interval in which the heart muscle is not excitable. They neither slow the stimulus conduction nor the excitability of the cells of the heart.
- WO-88/02362 are aryl-N-aminoalkyl-4- (sulfonamido) benzamides of the general formula
- the compounds of class III are particularly suitable for the treatment of cardiac arrhythmias, since they do not influence the conduction of stimuli or the excitability of the cardiac cells.
- the class III antiarrhythmics used to date have a number of side effects, some of which are considerable. These include, for example, nausea, vomiting, feeling of fullness, constipation, headache, dizziness, visual disturbances, sleep disturbances, sensitivity to sunlight, skin hyperpigmentation, sinus bradycardia, prolongation of the AV conduction time and pulmonary fibrosis.
- side effects make their use in medical practice considerably more difficult. There is therefore an urgent need for compounds which do not have these side effects or only have them to a minor extent.
- this object is achieved by creating new aralkyldiamine derivatives of the general formula I
- R ** L is a hydrogen atom or a benzoyl radical, the phenyl radical optionally being substituted by a halogen atom, a nitro group, an amino group, an alkyl or alkoxy group having up to four C atoms, a phenoxy group or a benzoyl group,
- R 2 is a hydroxymethyl, aminomethyl, aminocarboxymethyl or aminooxycarboxymethyl group
- R 3 and R 4 are the same or different and represent hydrogen atoms, alkyl, cycloalkyl, alkenyl, alkynyl or hydroxyalkyl radicals each having up to 6 carbon atoms, alkoxyalkyl, alkylthioalkyl or dialkylaminoalkyl radicals each having up to 9 C atoms, or phenylalkyl or phenoxyalkyl radicals with up to 6 C atoms in the alkyl part, where the phenyl radical is optionally substituted by an alkyl or alkoxy radical with up to 3 C atoms each,
- n is an integer between 1 and 8.
- R *** ⁇ is a p-nitrobenzoyl radical
- R j L is a p-nitrobenzoyl radical
- R 2 is a piperidinomethyl, morpholinomethyl, phenethylamino, methylamino methyl, ethylaminomethyl, diethylaminomethyl, dimethylaminomethyl, benzylaminomethyl, Alaninomethyl, anilinomethyl, p-toluidomethyl, pyrrolidinomethyl, piperazinomethyl, hydroxymethyl, acetoxymethyl, butyryloxymethyl, benzoyloxymethyl, N, N, N-dimethylglycyloxymethyl, N, N-diethylglycyloxymethyl -Dipropylglycyloxymethyl, nicotinoyloxymethyl, phenylalanyloxymethyl or le
