以
α-
倒捻子素为先导化合物,对其C-3及C-6位羟基进行结构修饰,经烷基化、水解反应引入不同碳链长度的羧酸酯、羧酸、酰胺取代基,设计并合成了18个衍生物。采用[
3
H]标记液体闪烁计数法测试了衍生物体外抑制磷酸二酯酶4(PDE4)活性。活性测试结果表明5个衍生物(
2a~6a
)的PDE4抑制活性优于
α
-倒捻子素,其中7碳链长度的羧酸类衍生物
5a
的活性最强(IC
50
319 nmol/L)。
Based on
α
-mangostin as the lead compound, and using the primary methods including alkylation and hydrolysis reactions for modifying C-3
and C-6 positions, eighteen novel derivatives with different chain length of carboxylic acid ester, carboxylic acid, and amide substituents in the C-3, C-6 phenolic hydroxyl group of
α
-mangostin were designed and synthesized. The
in vitro
evaluation of these compounds' ability to inhibit PDE4 was conducted using the [³H] liquid scintillation counting technique. The experimental results showed that five compound (
2a
-
6a
) had the stronger inhibitory activity on PDE4 than
α
-mangostin. Among them, carboxylic acid derivative of seven carbon chain lengths
5a
exhibited the best potential PDE4 inhibitory activity with the IC
50
values of 319 nmol/L.
