N-2,6-Disubstituted phenyl(-N'-3- and 4-pyridinyl ureas having the following general formula are disclosed:
A is a 3- or 4-pyridinyl radical; and R', R2 and R3 are independently chosen from a halogen atom, a lower alkyl radical, a lower alkoxy radical, a lower alkanoyl radical, a lower alkoxy carbonyl radical or a nitro group, with R3 additionally being chosen from a hydrogen atom. Processes for producing the compounds, pharmaceutical compositions compnsing the same, and pharmaceutically acceptable acid addition salts thereof are also disclosed. The compounds have anti-convulsant activity and are useful in the treatment of epilepsy.
本发明公开了具有以下通式的 N-2,6-二取代苯基(-N'-3-和 4-吡啶基)脲:
A是3-或4-吡啶基;R'、R2和R3独立地选自卤素原子、低级烷基、低级烷氧基、低级烷酰基、低级烷氧基羰基或硝基,R3另外选自氢原子。此外,还公开了这些化合物的生产工艺、包含这些化合物的药物组合物及其药学上可接受的酸加成盐。这些化合物具有抗惊厥活性,可用于治疗癫痫。
