lipophilic group and an aqueous-favoring group were introduced to the compounds 1 and 13 to afford twelve new derivatives. Their structures were elucidated by spectroscopic methods. The results of the pharmacological test indicated that some of them can block Ca (++) influx by occupying binding sites of dihydropyridine.
四苯并呋喃倍半萜、1-羟基-2-(3'-戊烯基)-3,7-二甲基苯并呋喃(1)、1-羟基-2-(3'-戊烯基)-3,7-二甲基苯并呋喃(2)、卡卡洛尔(13) ) 和 1,2-脱氢 cacalohastin (14) 是从 Ligularia virgaurea (Compositae) 的根茎中分离出来的。将亲脂基团和水相偏好基团引入化合物 1 和 13 中,得到 12 种新衍生物。它们的结构是通过光谱方法阐明的。药理试验结果表明,它们中的一些可以通过占据二氢吡啶的结合位点来阻断Ca(++)的流入。
