The invention relates to a group of new 3,5-substituted 1,2,4-oxadizoles, and the prodrugs and salts thereof. The compounds are represented by the formula
wherein
-R is a phenyl group which may be substituted with 1-3 halogen atoms, alkyl groups or alkoxy groups (1-4 C), or with CF₃, a group -O-(CH₂)m-O- wherein m has the value 1 or 2;
-X is the group (-CH=CH-)n, wherein n is 0 or 1;
-R₁ is hydrogen or alkyl having 1-4 C-atoms, and
-R₂ is a group -NR₃R₄, wherein R₃ and R₄ are saturated or unsaturated alkyl having 1-4 C-atoms;
and the prodrugs and salts thereof with pharmacologically acceptable acids.
It has been found that these compounds have interesting anti-convulsive activities, and are less toxic in comparison with related known compounds.
本发明涉及一组新的3,5-取代的1,2,4-噁二唑及其原药和盐。这些化合物由式
式中
-R 是苯基,可被 1-3 个卤素原子、烷基或烷氧基(1-4 C)取代,或被 CF₃、基团 -O-(CH₂)m-O-取代,其中 m 的值为 1 或 2;
-X 是基团 (-CH=CH-)n,其中 n 为 0 或 1;
-R₁是氢或具有 1-4 个 C 原子的烷基,以及
-R₂ 是基团 -NR₃R₄,其中 R₃ 和 R₄ 是具有 1-4 个 C 原子的饱和或不饱和烷基;
及其与药理学上可接受的酸的原药和盐。
研究发现,这些化合物具有有趣的抗惊厥活性,与相关的已知化合物相比毒性更低。
