Filing Date:Oct 03, 1977
Application Number:05/839,151
Claims:1. A method useful for the treatment of hirsutism which comprises administering to mammals suffering from hirsutism a therapeutically effective quantity for treating hirsutism of a substituted anilide having the structural formula: ##STR27## or the non-toxic pharmaceutically acceptable salts thereof, wherein X is a member selected from the group consisting of nitro, trifluoromethyl, chloro, bromo and iodo; Y is a member selected from 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 selected from 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 1 wherein R is cyclopropyl.

4. A method according to claim 2 wherein X is nitro.

5. A method according to claim 3 wherein X is nitro.

6. A method according to claim 2 wherein Y is trifluoromethyl.

7. A method according to claim 3 wherein Y is trifluoromethyl.

8. A method according to claim 2 wherein R' is hydrogen, Y is trifluoromethyl and X is nitro, said compound being 4'-nitro-3'-trifluoromethylisobutyranilide.

9. A method according to claim 2 wherein R' is hydrogen, Y is trifluoromethyl and X is iodo, said compound being 4'-iodo-3'-trifluoromethylisobutyranilide.

10. A method according to claim 3 wherein R' is hydrogen, Y is trifluoromethyl, and X is nitro, said compound being 4'-nitro-3'-trifluoromethylcyclopropylcarbanilide.

11. A method according to claim 1 wherein R' is hydrogen, X is nitro, Y is trifluoromethyl and R is 3'-methyl-2-butyl, said compound being 4'-nitro-3'-trifluoromethyl-2,3-dimethylbutyranilide.

12. A method according to claim 1 wherein R' is hydrogen, X is nitro, Y is trifluoromethyl and R is 2'-methyl propyl, said compound being 4'-nitro-3'-trifluoromethylisovaleranilide.

13. A method according to claim 1 wherein R' is hydrogen, X is bromo, Y is trifluoromethyl and R is isopropyl, said compound being 4'-bromo-3'-trifluoromethylisobutyranilide.

14. A method according to claim 1 wherein R' is hydrogen, X is chloro, Y is trifluoro and R is isopropyl, said compound being 4'-chloro-3'-trifluoromethylisobutyranilide.

15. A method according to claim 1 wherein R' is hydrogen, X is nitro, Y is bromo and R is isopropyl, said compound being 3'-bromo-4'-nitroisobutyranilide.

16. A method according to claim 1 wherein R' is hydrogen, X is nitro, Y is chloro and R is isopropyl, said compound being 3'-chloro-4'-nitroisobutyranilide.
