New fluoroalkyl-substituted pyrazolopyridine compounds are soluble guanylate cyclase stimulators, useful to treat e.g. heart disease, angina pectoris, hypertension, pulmonary hypertension, ischemia, vascular disease or renal insufficiency

摘要

Fluoroalkyl-substituted pyrazolopyridine compounds (I) are new. Fluoroalkyl-substituted pyrazolopyridine compounds of formula (I) and their N-oxides, salts, solvates, salts of N-oxides and solvates of the N-oxides or their salts are new. A : N or CR3; R3 : H, D, F, difluoromethyl, trifluoromethyl, 1-4C-alkyl, cyclopropyl or cyclobutyl; L : a1-CR4AR4B-(CR5AR5B) p-a2; a1 : point of attachment to the carbonyl group; a2 : point of attachment to the pyrimidine or triazine ring; p : 0-2; either R4A : H, F, 1-4C-alkyl, hydroxy or amino; and R4B : H, F, 1-4C-alkyl (optionally substituted with 1-3 substituents comprising F, trifluoromethyl, hydroxy, hydroxycarbonyl or 1-4C-alkoxycarbonyl), trifluoromethyl, 1-4C-alkoxycarbonylamino or phenyl; or R4A+C+R4B : 3-6 membered carbocycle or 4-6 membered heterocycle (both optionally substituted with 1 or 2 substituents comprising F or 1-4C-alkyl), oxo-group or 2-4C-alkenyl; R5A : H, F, 1-4C-alkyl or hydroxy; R5B : H, F, 1-4C-alkyl or trifluoromethyl; R1 : H or F; R2 : a3-(CR6AR6B) qCF 3; a3 : point of attachment to the pyrazolopyridine; R6A, R6B : H or F; and q : 1-3. 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 5,5-dimethyl-2-[1-(3,3,4,4,4-pentafluorobutyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]-5,7-dihydro-6H-pyrrolo[2,3-d]pyrimidin-6-one exhibited a minimal effective concentration of 0.03 mu M.
