Abstract

1391052 Pyrazolone derivatives BAYER AG 22 June 1973 [23 June 1972] 29786/73 Heading A5B A pharmaceutical composition contains as an active ingredient a compound which is a 3-amino-pyrazol-5-one of general formula: or its salt in which R is an aryl radical which carries either no substituents or the following substituents, (a) 1, 2 or 3 identical or different substituents selected from halogen, trifluoromethyl, alkyl, phenyl, alkoxy, and alkenoxy groups; or (b) one alkylamino, dialkylamino, trifluoromethoxy, nitro, nitrile, carbonamido, sulphonamido or SO n -Alkyl (n=0, 1 or 2) group and optionally also 1 or 2 substituents selected from alkyl, alkoxy, halogen and trifluoromethyl groups; or (c) an annellated branched or unbranched, saturated or unsaturated 5-, 6- or 7-membered-isocyclic or heterocyclic ring (which latter ring can optionally contain 1 or 2 oxygen andlor sulphur atoms) in admixture with a solid or liquefied gaseous diluent or in admixture with a liquid diluent other than a solvent of a molecular weight less than 200 except in the presence of a surface active agent. The active ingredient may be in the form of its sodium, potassium, ethanolamine, diethanolamine, triethanolamine, amino-tris-hydroxymethyl-methane, glucosamine or N-methyl-glucosamine salt. The compound may be used in the form of a sterile or isotonic solution. It may also be used with or without a diluent, as a medicament and in the form of tablets, pills, dragees, capsules, ampoules or suppositories. Suitable compounds exemplified are 3-aminol-(4-chlorobenzyl)-pyrazole- 5 - one, 3-amino- 1-(4-bromobenzyl)-pyrazol-5-one and 3-amino- 1-(3, 4-dimethylbenzyl)-pyrazol-5-one.
