Abstract
The invention provides new acetohydroxamic acid derivatives, having interesting properties on the central nervous system, of the formula: R.sub.1 R.sub.2 R.sub.3 C-CO-NHOH, in which R.sub.2 and R.sub.3 are each hydrogen or C.sub.1-6 alkyl, and R.sub.1 is C.sub.1-6 alkyl Z.sub.1 Z.sub.2 N (where Z.sub.1 and Z.sub.2 are each phenyl, substituted phenyl, or cycloalkyl), substituted hydantoinyl, benzhydroxylcarboxamido, Z.sub.3 CH.sub.2 -- (where Z.sub.3 = optionally substituted aryl), Z.sub.4 -A- (where Z.sub.4 is optionally substituted phenyl or naphthyl, and A is --NH--, --N(C.sub.1-4 alkyl)--, --N(C.sub.5-6 cycloalkyl)--, --NHCO--, --N(C.sub.1-4 alkyl)CO--, --N(C.sub.5-6 cycloalkyl)CO--, --CONH--, --CON(C.sub.1-4 alkyl)--, --CON(C.sub.5-6 cycloalkyl)--, --NHCONH--, --N(C.sub.5 H.sub.6)CONH--, or --N(substituted phenyl)CONH--, optionally substituted benzimidazolyl, or an optionally substituted tricyclic radical, and their metal and acid addition salts.
