Abstract
Novel 2-(N-substituted-aminoalkyl)-5-(E)-alkylidene cyclopentanones, 2-(N-substituted-aminoalkyl)-5-(E)-arylalkylidene cyclopentanones, and derivatives thereof having the formula ##STR1## wherein x is methylene or ethylene; R.sub.1 is dimethylamino, diethylamino, 1-pyrrolidinyl, 1-piperidinyl, 4-morpholinyl, anilino or substituted anilino; R.sub.2 is hydrogen, straight or branched alkyl of 1 to 9 carbon atoms, aryl or arylalkyl; R.sub.3 is hydrogen, straight or branched alkyl of 1 to 9 carbon atoms, aryl or arylalkyl; and R.sub.4 is hydrogen, methyl, ethyl, allyl, benzyl, substituted benzyl, cyclopentyl, substituted cyclopentyl, cyclopenten-1-yl, or substituted cyclopenten-1-yl; and wherein aryl is phenyl or phenyl substituted with one or more methoxyl, hydroxyl, methylenedioxy, chloro, bromo, fluoro, ethoxycarbonylmethoxy, benzoxy, alkyl group, or their combination, possess anti-inflammatory, analgesic and anticancer properties. The methods of using these compounds to treat inflammation, pain and cancer in mammals and to resist or substantially prevent inflammation and pain in mammals are also disclosed.
