Independent claims are included for: (1) the preparation of (I); and (2) a drug comprising (I) in combination with further active agents comprising organic nitrates, nitric oxide donors, cyclic guanosine monophosphate-phosphodiesterase inhibitors, antithrombotic agents, blood pressure lowering agents or lipid modifying agents. [Image] ACTIVITY : Cardiant; Antianginal; Hypotensive; Respiratory-Gen.; Vasotropic; Nephrotropic; Thrombolytic; Antiinflammatory; Antiarteriosclerotic; Antiarrhythmic; Cardiovascular-Gen.; Antibacterial; Immunosuppressive; Antiallergic; Cerebroprotective; Endocrine-Gen.; Antidiabetic; Antilipemic; Hemostatic; Anorectic; Ophthalmological; Antiulcer; Antianemic; Antiasthmatic; CNS-Gen.; Nootropic; Vulnerary; Neuroprotective; Antiparkinsonian; Anticonvulsant; Neuroleptic; Tranquilizer; Antidepressant; Hypnotic; Antimigraine; Gastrointestinal-Gen.; Dermatological; Cytostatic. MECHANISM OF ACTION : Soluble guanylate cyclase stimulator. The soluble guanylate cyclase stimulating activity of (I) was tested in a recombinant guanylate cyclase reporter cell line using an in vitro assay. The results showed that 3-(5-fluoro-1-[(3-fluoro-2-thienyl)methyl]-1H-pyrazolo[3,4-b]pyridin-3-yl)-7,7-dimethyl-5,7-dihydro-6H-pyrrolo[2,3-e][1,2,4]triazin-6-one exhibited a minimal effective concentration of 0.01 mu M.
