Selaginellin derivatives 1-3 isolated from Selaginella tamariscina were evaluated for their inhibition of soluble epoxide hydrolase (sEH) to demonstrate their potential for the treatment of cardiovascular disease. All selaginellin derivatives (1-3) inhibited sEH enzymatic activity and PHOME hydrolysis, in a dose-dependent manner, with IC50 values of 3.1 ± 0.1, 8.2 ± 2.2, and 4.2 ± 0.2 μM, respectively. We further determined that the derivatives function as non-competitive inhibitors. Moreover, the predicted that binding sites and interaction between 1-3 and sEH were solved by docking simulations. According to quantitative analysis, 1-3 were confirmed to have high content in the roots of S. tamariscina; among them, selaginellin 3 exhibited the highest content of 189.3 ± 0.0 μg/g.
对从卷柏中分离得到的卷柏素衍生物1-3进行了可溶性环氧化物水解酶（sEH）抑制活性评价，以证明其治疗心血管疾病的潜力。所有卷柏素衍生物（1-3）均以剂量依赖性方式抑制sEH酶活性和对羟基苯甲酯（PHOME）水解，IC50值分别为3.1±0.1、8.2±2.2和4.2±0.2μM。我们进一步确定这些衍生物起非竞争性抑制剂的作用。此外，通过对接模拟解析了1-3与sEH之间的预测结合位点和相互作用。根据定量分析，证实1-3在卷柏根部含量较高；其中，卷柏素3含量最高，为189.3±0.0μg/g。
