  • Patent number: 4025649
    Abstract: Acetic acid derivatives of the formula: ##STR1## and pharmaceutically acceptable alkali metal salts thereof, wherein R represents the radical ##STR2## in which R.sub.1 and R.sub.2, which may be the same or different, each represent an alkyl radical having from 1 to 4 carbon atoms, R.sub.3 represents a hydrogen atom or a methyl radical and n is an integer in the range of from 0 to 3 inclusive.They possess a competitive inhibitory activity with respect to .gamma.-aminobutyric .alpha.-ketoglutaric transaminase as well as antianoxic and anticonvulsant properties and they are useful for treating central neurological disorders whether resulting or not from cerebral ischemia.

  • Patent number: 3984470
    Abstract: Amidoxime derivatives corresponding to the general formula: ##EQU1## and pharmaceutically acceptable acid addition salts thereof, wherein R.sub.1 and R.sub.2, which are the same or different, represent hydrogen or a straight-chain lower alkyl radical containing from 1 to 3 carbon atoms, n is 0, 1 or 2 and R is selected from the groups consisting of: ##SPC1##Wherein X represents oxygen or sulphur, Y . . . Z represents HC--CH or C=C, R.sub.3 and R.sub.4, which are the same or different, represent hydrogen or a branched- or straight-chain lower alkyl radical containing from 1 to 3 carbon atoms with the provisos that:A. when n is 1, R.sub.1 and R.sub.2 are each hydrogen and R is selected from the groups A, B, C and D.b. when n is 2, R.sub.1 and R.sub.2 area each hydrogen and R is selected from the groups A, B, C and the group D when it represents .beta.-naphthyl.They are effective as antidepressive and antiaggressive agents.
