|Filing Date:||Sep 11, 1974|
|Claims:||1. A method for the treatment of benign prostatic hypertrophy which comprises administering to mammals suffering from benign prostatic hyperstrophy, an effective quantity for treating benign prostatic hypertrophy of a compound having the structural formula: ##SPC26## |
or the non-toxic pharmaceutically acceptable salts thereof, wherein X is a member of the group consisting of nitro, trifluoromethyl, chloro, bromo and iodo; Y is a member of the group consisting of hydrogen, halogen, nitro, lower alkyl, lower alkoxy, lower alkanoyl, polyfluoroloweralkoxy, polyfluoroloweralkyl, and trifluoromethylthio, with the proviso that when Y and R' are both hydrogen, X is other than iodo; R' is a member of the group consisting of hydrogen and alkyl having less than 5 carbon atoms and R is cyclopropyl, cyclobutyl or branched chain alkyl having up to 8 carbon atoms.
2. A method according to claim 1 wherein R is isopropyl.
3. A method according to claim 2 wherein R' is hydrogen. Y is trifluoromethyl and X is nitro, said compound being 4'-nitro-3'-trifluoromethylisobutyranilide.
4. A method according to claim 2 wherein R' is hydrogen, Y is trifluoromethyl and X is iodo, said compound being 4'-iodo-3'-trifluoromethylisobutyranilide.
5. A method according to claim 1 wherein R is cyclopropyl.
6. A method according to claim 5 wherein R' is hydrogen, Y is trifluoromethyl, and X is nitro, said compound being 4'-nitro-3'-trifluoromethylcyclopropylcarbanilide.
