Bicyclic analogues of the plant hormone abscisic acid (ABA) were designed to incorporate the structural elements and functional groups of the parent molecule that are required for biological activity. The resulting tetralone analogues were predicted to have enhanced biological activity in plants, in part because oxidized products would not cyclize to forms corresponding to the inactive catabolite phaseic
植物激素脱落酸(ABA)的双环类似物被设计为纳入生物活性所需的母体分子的结构元素和官能团。预测所得的四氢萘酮类似物在植物中具有增强的生物活性,部分原因是氧化产物不会环化成与无活性分解代谢物相酸相对应的形式。四氢萘酮类似物是从1-四氢萘酮七步合成的,一系列类似物可通过以2-甲基-1-萘酚为起始的第二种途径获得。在两种生物测定中,发现四氢萘酮ABA 8具有比ABA更大的活性。(+)-8的绝对构型是通过RAMP hydr衍生物的X射线晶体学确定的。羟甲基化合物10和11
