Endothelial dysfunction is a key pathological feature of many inflammatory diseases, including sepsis. In the present study, a new caffeoyl glucoside (1) and two known caffeoylated compounds (2 and 3) were isolated from the fruits of Nandina domestica Thunb. (Berberidaceae). The compounds were investigated for their effects against lipopolysaccharide (LPS)-mediated endothelial inflammatory responses. At 20 μM, 1 and 2 inhibited LPS-induced hyperpermeability, adhesion, and migration of leukocytes across a human endothelial cell monolayer in a dose-dependent manner suggesting that 1 and 2 may serve as potential scaffolds for the development of therapeutic agents to treat vascular inflammatory disorders.
内皮功能障碍是包括脓毒症在内的多种炎症性疾病的关键病理特征。在本研究中，从南天竹（小檗科）果实中分离出一种新的咖啡酰葡萄糖苷（1）和两种已知的咖啡酰化化合物（2和3）。研究了这些化合物对脂多糖（LPS）介导的内皮炎症反应的影响。在20 μM浓度下，化合物1和2以剂量依赖的方式抑制LPS诱导的人内皮细胞单层的通透性增加、白细胞黏附和迁移，这表明化合物1和2可能作为开发治疗血管炎症性疾病治疗药物的潜在骨架。
