Généralement, dans le passé, les médicaments anti-30 inflammatoires puissants se sont révélés produire des effets secondaires graves d'hémorragies et d'ulcérations gastriques par administration orale aux animaux dans une gamme efficace. Les composés de 5 l'invention se sont révélés avoir pour avantage de réduire la fréquence de l'irritation gastrique que l'on observe lorsqu'on les administre dans la gamme efficace pour réduire l'inflammation, par rapport à 1'indométhacine et aux acides amino-2 benzoyl-3 phényl-5 acétiques et leurs dérivés décrits dans le brevet des Etats-Unis d'Amérique n° 4 045 576. Par exemple, le composé de l'exemple 2, l'amino-2 (chloro-4 benzoyl)-3 méthyl-5 phénylacétate de sodium, s'est révélé être environ deux fois plus actif que 1'indométhacine et l'amino-2 benzoyl-3 phénylacétate de sodium en ne provoquant 10 qu'un quart de l'irritation de l'estomac que provoque 1'indométhacine et environ la moitié de l'irritation de l'estomac que provoque l'amino-2 benzoyl-3 phénylacétate de sodium. Le composé de l'exemple 2 s'est révélé avoir environ la moitié de l'activité de l'amino-2 (chloro-4 benzoyl)-3 fluoro-5 phénylacétate de sodium, mais ne 15 provoquer qu'environ le quart de l'irritation de l'estomac que provoque ce composé.Generally, in the past, potent anti-inflammatory drugs have been shown to produce severe side effects of hemorrhages and gastric ulcers by oral administration to animals in an effective range. The compounds of the invention have been shown to have the advantage of reducing the frequency of gastric irritation observed when administered in the range effective to reduce inflammation, compared to indomethacin and 2-amino-3-benzoyl-5-phenylacetic acids and their derivatives described in US Pat. No. 4,045,576. For example, the compound of Example 2, amino-2 (chloro- Sodium benzoyl) -3 methyl-5 phenylacetate, has been shown to be approximately twice as active as indomethacin and sodium amino-2 benzoyl-3 phenylacetate, causing only a quarter of the irritation of the stomach caused by indomethacin and about half of the stomach irritation caused by 2-amino-3-benzoyl-phenylacetate. The compound of Example 2 was found to have about half the activity of sodium amino-2 (4-chloro-benzoyl) -5 fluoro-phenylacetate, but to cause only about a quarter of stomach irritation caused by this compound.
L'activité anti-inflammatoire a été mise en évidence sur l'animal de laboratoire selon une modification du test d'épanchement pleural au bleu Evans et au carragéénane de Sancilio, L.F., 20 J.
