Phenyl-3-aminoalkyl-4-methyl-2,6-dioxopiperidines of the Formula I
wherein:
R₁ represents hydrogen or C₁-C₄ alkyl;
n is 1 or 2;
R₂ represents hydrogen or methyl, provided that one R₂ is hydrogen when n is 2;
R₃ represents hydrogen or C₁-C₂ alkyl;
R₄ represents C₁-C₂ alkyl;
R₅ and R₆ independently represent hydrogen or methyl;
m is 0 to 3; and
each Y is in a meta or para position and independently represents hydroxy, C₁-C₂ alkoxy, C₁-C₂ alkyl, C₁-C₂ hydroxyalkyl, halogen, or trifluoromethyl, provided that hydroxy and alkoxy are not in the para position,
and pharmacologically acceptable salts thereof antagonise anxiogenesis associated with withdrawal from addictive drugs, especially alcohol, cocaine and nicotine.
The presently preferred compound is 3-(3′methoxyphenyl)-3-(3˝-N,N-dimethylaminopropyl) -4,4-dimethyl-2,6-dioxopiperidine (AGN 2979).
