Definitions

  • the present application relates to novel 3-tetrazoyl-indazole and 3-tetrazolyl-pyrazolo [3,4-b] pyridine derivatives, processes for their preparation, their use alone or in combinations for the treatment and / or prevention of diseases and their Use for the production of medicaments for the treatment and / or prevention of diseases, in particular for the treatment and / or prevention of cardiovascular diseases.
  • cyclic guanosine monophosphate cGMP
  • NO nitric oxide
  • the guanylate cyclases catalyze the biosynthesis of cGMP from guanosine triphosphate (GTP).
  • GTP guanosine triphosphate
  • the previously known members of this family can be divided into two groups according to both structural features and the nature of the ligands: the particulate guanylate cyclases stimulable by natriuretic peptides and the soluble guanylate cyclases stimulable by NO.
  • the soluble guanylate cyclases consist of two subunits and most likely contain one heme per heterodimer, which is part of the regulatory center. This is central to the activation mechanism. NO can bind to the iron atom of the heme and thus significantly increase the activity of the enzyme. On the other hand, heme-free preparations can not be stimulated by NO. Carbon monoxide (CO) is also able to bind to the central iron atom of the heme, with stimulation by CO being markedly lower than by NO.
  • CO Carbon monoxide
  • guanylate cyclase plays a crucial role in various physiological processes, in particular in the relaxation and proliferation of smooth muscle cells, platelet aggregation and adhesion, neuronal signaling and diseases based on a disturbance of the above operations.
  • the NO / cGMP system may be suppressed, which may, for example, lead to hypertension, platelet activation, increased cell proliferation, endothelial dysfunction, atherosclerosis, angina pectoris, heart failure, myocardial infarction, thrombosis, stroke and sexual dysfunction.
  • a NO-independent treatment option for such diseases which is aimed at influencing the cGMP pathway in organisms, is a promising approach on account of the expected high efficiency and low side effects.
  • soluble guanylate cyclase only compounds such as organic nitrates have been used, whose action is based on NO. This is formed by bioconversion and activates the soluble guanylate cyclase by attack on the central iron atom of the heme.
  • the development of tolerance is one of the decisive disadvantages of this type of treatment.
  • heterocyclic substituted, fused pyrazole derivatives are described inter alia in WO 98/16507, WO 98/23619 and WO 00/06569 as stimulators of soluble guanylate cyclase.
  • these compounds have disadvantages in terms of their in vivo properties, such as their behavior in the liver, their pharmacokinetic behavior, their dose-response relationship and / or their metabolic pathway.
