- Method of treating muscular tension, muscle spasticity and anxiety with 3-aryloxy and 3-arylthioazetidinecarboxamides
-
A method of treating animals to obtain muscle relaxation and/or to relieve anxiety is disclosed utilizing novel and known 3-aryloxy and 3-arylthioazetidinecarboxamides having the formula: STR1 wherein Z is oxygen or sulfur; B is oxygen or sulfur; Ar is pyridyl or halo substituted pyridyl, phenyl or substituted phenyl; R1 and R2 are hydrogen, loweralkyl, aryl, allyl groups, propargyl, cycloalkyl, loweralkylcycloalkyl, cycloalkylloweralkyl, arylloweralkyl and diloweralkylaminoalkyl, and R1 and R2 when taken together with the adjacent nitrogen atom may form a heterocyclic amine radical; R3 is hydrogen, loweralkyl, aryl or arylloweralkyl, and the geometrical isomers thereof and pharmaceutical salts thereof and hydrates thereof when they are possible.

- 3-aryloxy and 3-arylthioazetidinecarboxamides as anticonvulsants and antiepileptics
-
Novel 3-aryloxy and 3-arylthioazetidinecarboxamides having utility in a method of treating convulsions and epilepsy and compositions therefor are disclosed having the formula: STR1 wherein Z is oxygen or sulfur; B is oxygen or sulfur; Ar is pyridyl or halo-substituted-pyridyl, phenyl or substituted phenyl; R1 and R2 are selected from hydrogen, loweralkyl, aryl, allyl, substituted allyl, propargyl, cycloalkyl, loweralkylcycloalkyl, cycloalkylloweralkyl, arylloweralkyl, diloweralkylaminoloweralkyl, and R1 and R2 when taken with the adjacent nitrogen atom may form a heterocyclic radical; R3 is hydrogen, loweralkyl, aryl or arylloweralkyl, and the geometrical isomers thereof, excepting that when R3 is hydrogen, Z is oxygen, B is oxygen, and Ar is phenyl or phenyl substituted by trifluoromethyl or aminocarbonyl, then R1 and R2 cannot be a combination of hydrogen and loweralkyl, and the further exception that when R3 is hydrogen, Z is oxygen, B is oxygen, and Ar is phenyl or phenyl substituted by fluoro, loweralkyl, loweralkoxy, trifluoromethyl, acetyl, or aminocarbonyl, then R1 and R2 cannot both be hydrogen.
