In order to look for new active compounds, the structure of (+)-praeruptorin A is modified.
(+)-Praeruptorin A was isolated from the root of Peucedanum praeruptorum, basic hydrolysis of (+)-praeruptorin A and acyled reactions of hydrolysis product of (+)-praeruptorin A were carried out.
Eighteen compounds were semi-synthesized from (+)-praeruptorin A.
Fourteen compounds (5-18) among them are new compounds. Preliminary bioactivity assay indicated that the new compounds show calcium antagonist activity, but they are not as strong as (+)-praeruptorin A.
为寻找新的活性化合物，对（+）-前胡素A的结构进行修饰。
从白花前胡根中分离得到（+）-前胡素A，对其进行碱性水解以及水解产物的酰化反应。
由（+）-前胡素A半合成了18个化合物。
其中14个化合物（5 - 18）为新化合物。初步生物活性测定表明，这些新化合物具有钙拮抗剂活性，但活性不如（+）-前胡素A强。
