Abstract:
The invention relates to 6-substituted isoquinoline and isoquinolinone derivatives of the formula (I) useful for the treatment and/or prevention of diseases associated with Rho-kinase and/or Rho-kinase mediated phosphorylation of myosin light chain phosphatase, and compositions containing such compounds.
Abstract:
Pentafluorosulfanylbenzoylguanidines of the formula I and II in which R1 to R4 have the meanings stated in the claims, are suitable as antiarrhythmic medicaments with a cardioprotective component for the prophylaxis of infarction and treatment of infarction and for the treatment of angina pectoris.They also inhibit preventively the pathophysiological processes associated with the development of ischemia-induced damage, especially in the triggering of ischemia-induced cardiac arrhythmias.

Abstract:
Di(hetero)arylcyclohexane derivatives, their preparation, their use and pharmaceutical compositions comprising themThe 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.
Abstract:
The present invention relates to heteroaryl-substituted carboxamides of the formula I, in which Het, A, X, R1, R2 and R3 have the meanings indicated in the claims, which modulate the transcription of endothelial nitric oxide (NO) synthase and are valuable pharmacologically active compounds. Specifically, the compounds of the formula I upregulate the expression of the enzyme endothelial NO synthase and can be applied in conditions in which an increased expression of said enzyme or an increased NO level or the normalization of a decreased NO level is desired. The invention further relates to processes for the preparation of compounds of the formula I, to pharmaceutical compositions comprising them, and to the use of compounds of the formula I for the manufacture of a medicament for the stimulation of the expression of endothelial NO synthase or for the treatment of various diseases including cardiovascular disorders such as atherosclerosis, thrombosis, coronary artery disease, hypertension and cardiac insufficiency, for example.
Abstract:
