1,4-dihydropyridine derivatives represented by the formula:
wherein
R¹ and R², different from the other, is selected from the group consisting of lower alkyl, lower alkenyl, lower alkoxyalkyl or aminoaryl(lower)alkyl having carbon atoms of 1 to 6, which may be substituted or unsubstituted by a lower alkyl having carbon atoms of 1 to 4, wherein at least one of R¹ and R² is a lower alkenyl having carbon atoms of 3 to 6 whose 1- or 2- position is substituted by a lower alkyl having carbon atoms of 1 to 4; and
R³ is a nitro group in ortho-, meta- or para-position of the phenyl.
The compounds are useful as vasodilators and in the treatment of hypertension.
1,4-二氢吡啶衍生物的化学式表示为:其中R¹和R²,不同于另一个,选自由1至6个碳原子的较低烷基、较低烯基、较低烷氧基烷基或氨基芳基(较低)烷基组成的基团,该基团可能被1至4个碳原子的较低烷基取代或未取代,其中R¹和R²中至少一个是碳原子为3至6的较低烯基,其1-或2-位置被1至4个碳原子的较低烷基取代;以及R³是苯环的邻位、间位或对位的硝基基团。这些化合物可用作扩血管剂,并用于治疗高血压。
