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,
