Abstract: Anti-inflammatory compositions are prepared which comprise a therapeutically effective amount of a compound of the formula ##STR1## wherein X is CO or CHOH; Y is CO, an oxygen atom or a direct bond; the dotted line represents a double bond which is optionally present when Y is an oxygen atom or a direct bond; R.sub.1 is hydrogen or methyl; R.sub.2 is hydrogen, fluorine, chlorine, bromine, methyl, trifluoromethyl, methoxyl, hydroxyl, acetoxyl, nitro or amino; R.sub.3 is alkyl of 3-8 carbon atoms, cycloalkyl of 3-8 carbon atoms, alkenyl of 3-8 carbon atoms, cycloalkenyl of 5-8 carbon atoms, phenyl or phenyl substituted by 1 or 2 substituents selected from the group consisting of fluorine, chlorine, bromine, methyl, ethyl, methoxyl, ethoxyl, benzyloxyl, hydroxyl, acetoxyl, trifluoromethyl, nitro, amino, acetyl, methylthiol, methylsulphonyl, methylamino and dimethylamino.Compounds of the above formula are novel except that R.sub.1 must be methyl: when R.sub.3 -- Y is a 4-phenyl group, R.sub.

Abstract: 4-(6'-Methoxy-2'-naphthyl) butan-2-one is described as having anti-inflammatory activity and an improved therapeutic ratio.

Abstract: Compounds of the formula (II): ##SPC1##wherein R.sub.1 is an aliphatic moiety of 1-12 carbon atoms, a cycloaliphatic moiety of 3-7 carbon atoms or said aliphatic moiety or said cycloaliphatic moiety substituted by halogen, carboxylic acid, esterified carboxylic acid, carboxamide, nitro, hydroxyl, etherified hydroxyl, acylated hydroxyl, amino, alkylamino, dialkylamino or acylated amino: R.sub.2 is a hydrocarbon of 1-7 carbon atoms: R.sub.3 is amino, lower alkylamino, di-lower alkylamino, anilino or lower alkoxyl; R.sub.4 is hydrogen, R.sub.5 or CO.R.sub.5 wherein R.sub.5 is a hydrocarbon of 1-7 carbon atoms, are useful for their anti-inflammatory activity.
