Abstract

Four unprecedented nortriterpenoids, masterpenoids A-D, were isolated and fully elucidated from the resin of the mastic tree (Pistacia lentiscus). Masterpenoids A-C are the first norterpenoids featuring an unprecedented 6/6/6/10 ring system, while masterpenoid D possesses a novel 6/6/6/7/5 ring system. The anti-inflammatory potential of the compounds was meticulously assessed through the establishment of an in vitro model of lipopolysaccharide-induced inflammation in RAW264.7 macrophage cells. Among them, Masterpenoids A and D showed potent inhibition of NO production, with IC₅₀ values of 10.6 ± 0.8 and 8.2 ± 0.9 μM, respectively, compared to positive control dexamethasone (IC₅₀ = 23.2 ± 1.2 μM).

从麝香草（Pistacia lentiscus）中提取的 Masterpenoids A-D, 四种前所未有的 Nortriterpenoids 及其抗炎活性。

从麝香树（Pistacia lentiscus）的树脂中分离并完全阐明了四种前所未有的北萜类化合物，即主萜 A-D。主萜 A-C 是首个具有前所未有的 6/6/6/10 环系统的北三萜类化合物，而主萜 D 则具有新颖的 6/6/6/7/5 环系统。通过在 RAW264.7 巨噬细胞中建立脂多糖诱导的体外炎症模型，对这些化合物的抗炎潜力进行了细致的评估。与阳性对照地塞米松（IC50 = 23.2 ± 1.2 μM）相比，类萜 A 和 D 能有效抑制 NO 的产生，IC50 值分别为 10.6 ± 0.8 和 8.2 ± 0.9 μM。
