CA 2689985

The present invention relates to di(hetero)arylcyclohexane derivatives of the formula (I), in which Ar1, Ar2, R1 and R2 have the meanings indicated in the claims. The compounds of the formula (I) are valuable pharmaceutical active compounds which inhibit ATP-sensitive potassium channels in the heart muscle and are suitable, for example, for the treatment of disorders of the cardiovascular system such as arrhythmias or a decreased contractility of the heart, such as can occur, for example, in coronary heart disease, cardiac insufficiency or cardiomyopathies. In particular, they are suitable for the prevention of sudden cardiac death. The invention furthermore relates to processes and intermediates for the preparation of the compounds of the formula (I), their use and pharmaceutical compositions comprising them.

La présente invention porte sur des dérivés de di(hétéro)arylcyclohexane représentés par la formule (I), dans laquelle Ar1, Ar2, R1 et R2 ont les significations indiquées dans les revendications. Les composés de la formule (I) sont des composés pharmaceutiques actifs servant à inhiber les canaux potassiques sensibles à l'ATP dans le muscle cardiaque et sont appropriés, par exemple, pour le traitement de troubles du système cardiovasculaire tels que des arythmies ou une contractilité cardiaque diminuée qui se produisent, par exemple, lors d'une coronaropathie, d'une insuffisance cardiaque ou des cardiomyopathies. En particulier, les composés sont utiles dans la prévention d'une mort cardiaque subite. L'invention porte, de plus, sur des procédés et des intermédiaires servant à la préparation des composés de la formule (I), sur leur utilisation et sur des compositions pharmaceutiques les comprenant.
