heteroatom. In addition, several related examples, having additional nuclear substituents and/or groups other than CN in the position adjacent to the aminohydroxypropoxy group, were prepared, and beta-adrenoceptor antagonist activity and vasodilating potency were determined. Three compounds, thiazole 2 and isothiazoles 3 and 27, effectively lowered mean arterial pressure in the SH rat at 5 mg/kg. Compounds
描述了一系列(S)-2- [3-(叔丁基
氨基)-2-羟基丙氧基] -3-
氰基吡啶(1)的等电子类似物的合成;在该组中包括
噻唑,
异噻唑,
噻二唑,
吡嗪和与结构相关的
萘啶的实例。所有化合物都与1相似,因为它们在
氨基羟基丙氧基侧链的邻位和在氮杂原子的间位含有一个
氰基。另外,制备了几个相关的实施例,其在与
氨基羟基丙氧基相邻的位置具有另外的核取代基和/或除CN以外的基团,并且确定了β-
肾上腺素受体拮抗剂活性和血管舒张能力。
噻唑2和
异噻唑3和27这三种化合物以5 mg / kg的剂量有效降低了SH大鼠的平均动脉压。化合物2、3,
