Definitions
- the present invention relates to new chemical compounds which stimulate soluble guanylate cyclase, their preparation and their use as medicaments, in particular as medicaments for the treatment of cardiovascular diseases.
- Cyclic guanosine monophosphate is one of the most important cellular transmission systems in mammalian cells. Together with nitrogen monoxide (NO), which is released from the endothelium and transmits hormone-like and mechanical signals, it forms the NO / cGMP system.
- NO nitrogen monoxide
- the guanylate cyclases catalyze the biosynthesis of cGMP from guanosine triposphate (GTP).
- GTP guanosine triposphate
- the previously known representatives of this family can be divided into two groups according to both structural features and the type of ligand: the particulate guanylate cyclases that can be stimulated by natriuretic peptides and the soluble guanylate cyclases that can be stimulated 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 of central importance for the activation mechanism. NO can bind to the iron atom of the heme and so the
- guanylate cyclase plays a decisive role in different physiological processes, in particular in the relaxation and proliferation of smooth muscle cells, platelet aggregation and adhesion and neuronal signal transmission as well as in diseases which are based on a disturbance of the above-mentioned processes.
- the NO / cGMP system can be suppressed in physiological conditions, which can lead, for example, to high blood pressure, platelet activation, increased cell proliferation, endothelial dysfunction, atherosclerosis, angina pectoris, heart failure, thromboses, stroke and myocardial infarction.
- a NO-independent treatment option for such diseases aimed at influencing the cGMP signal path in organisms is a promising approach due to the expected high efficiency and few side effects.
