Terpenoids isolated from Chinese liverworts Lepidozia reptans and their anti-inflammatory activity

Bioorg Med Chem. 2018 May 15;26(9):2392-2400. doi: 10.1016/j.bmc.2018.03.040. Epub 2018 Mar 27.

Abstract

Five new terpenoids (1-5) including two dollabellane-type, one ent-kaurane-type diterpenoids and two sesquiterpenoids were isolated from the Chinese liverwort Lepidozia reptans (L.) Dumort., together with nine known terpenoids (6-14). Their structures were determined on the basis of analysis of MS and NMR spectroscopic data, single-crystal X-ray diffraction and electronic circular dichroism calculations. The selected compounds 1, 2, 6, 7, 9 and 14 were screened for anti-inflammatory activities by the model of LPS-induced nitric oxide (NO) production with macrophage cells, and the mechanism of the active compounds 1 and 2 were further explored.

Keywords: Anti-inflammatory; Liverworts; Terpenoids.
