A method of preventing epileptic seizures in a human or lower animal subject susceptible to said seizures, comprising systemically administering to said subject a safe and effective amount of a compound of the formula:
wherein
(a) X is halo or nil, and Y is a substituent selected from the group consisting of unsubstituted or halogen-substituted methyl, halo, nitro, amino, and methoxy; and
(b) R is N(R³)₂, OR¹N(R³)₂, N(R²)R¹N(R³)₂, or N(R²)N(R³)₂; where
R¹ is C₁-C₃ alkyl which is unsubstituted or substituted with C₁-C₂ alkyl;
R² is hydrogen or lower alkyl; and
each R³ is, independently, hydrogen or lower alkyl, or both R³ groups are connected to form a saturated 5- or 6-membered heterocycle containing 1 or 2 heteroatoms selected from oxygen and nitrogen and said heterocycle is unsubstituted or substituted with lower alkyl or hydroxy-substituted lower alkyl;
or a pharmaceutically-acceptable salt thereof.
Preferably X is halo, preferably Y is trifluoromethyl, and R is preferably 3-diethylamino-2,2-dimethylpropoxy.
一种预防易受所述癫痫发作影响的人类或低等动物的癫痫发作的方法,包括向所述受试者全身施用安全有效量的式化合物:
其中
(a) X 是卤代或无,Y 是选自由未取代或卤代甲基、卤代、硝基、氨基和甲氧基组成的组的取代基;和
(b) R 是 N(R³)₂、OR¹N(R³)₂、N(R²)R¹N(R³)₂ 或 N(R²)N(R³)₂; 其中
R¹ 是未取代或被 C₁-C₂ 烷基取代的 C₁-C₃ 烷基;
R² 是氢或低级烷基;以及
每个 R³ 独立地为氢或低级烷基,或两个 R³ 基团连接形成饱和的 5 或 6 元杂环,该杂环含有 1 或 2 个选自氧和氮的杂原子,且所述杂环未被取代或被低级烷基或羟基取代的低级烷基取代;
或其药学上可接受的盐。
X最好是卤代,Y最好是三氟甲基,R最好是3-二乙氨基-2,2-二甲基丙氧基。
