1391051 Aminopyrazolones BAYER AG 22 June 1973 [23 June 1972] 29785/73 Heading C2C The invention comprises compounds of the tautomeric formulae and their salts, wherein R is (a) a phenyl radical carrying one or two identical or different substituents selected from alkyl, phenyl, trifluoromethyl, trifluoromethoxy, nitro, nitrile, carbamoyl, sulphamoyl, alkylamino, fluorine, bromine and iodine radicals but cannot be a phenyl radical carrying trifluoromethyl only as one substituent, or (b) a phenyl radical carrying an annellated, branched or unbranched, saturated or unsaturated, five to seven-membered isocyclic or heterocyclic ring (the heterocyclic ring containing one or more oxygen and/or sulphur atoms); or (c) a phenyl radical carrying as substituent an SO n -alkyl group (n = 0, 1 or 2), an alkoxy group, or an -O-(CH 2 ) n -N(alkyl) 2 group (n = 2 or 3); or (d) a phenyl radical carrying two identical substituents selected from alkoxy and trifluoromethyl groups; or (e) a phenyl radical carrying two different substituents selected from alkyl, phenyl, halogen, alkoxy, trifluoromethyl, trifluoromethoxy, alkylamino, nitrile, carbamoyl, sulphamoyl, -SO n alkyl (n = 0, 1 or 2) and nitro radicals; or (f) a trichlorophenyl radical; or (g) a naphthyl radical carrying one or two identical or different substituents selected from halogen atoms and alkyl groups; or (h) an unsubstituted #-naphthyl, anthryl or phenanthryl radical. These compounds are prepared by reacting RCH 2 NHNH 2 with CNCH 2 COX or where X is OH, alkoxy, aralkoxy, NH 2 or alkylamino, and Y is alkoxy, aryloxy, aralkoxy, alkylmercapto, aralkylmercapto or NH 2 . Therapeutic compositions having diuretic, saluretic and antihypertensive activity comprise compounds of the above formulae, and may be administered orally, parenterally, rectally, topically or by means of a spray. |
