Chinese Journal of Natural Medicines 2024年第10期22卷 945-954页

作者： WANG Didi mei Fang NIE Jinchun LI Zhenwei ZHANG Daidi GUO Dean LI wei School of Pharmacy Guizhou Medical University Zhongshan Institute for Drug Discovery Shanghai Institute of Materia Medica Chinese Academy of Sciences

The phytochemical investigation of the leaves and twigs of Croton yunnanensis resulted in the isolation of eight new clerodane furanoditerpenoids, named croyunfuranoids A-H（1-8）, along with three known analogs（9-11）. The structures of these compounds were elucidated using spectroscopic analyses, and their absolute configurations were determined through a combination of electronic circular dichroism（ECD） calculations and single-crystal X-ray diffraction. Notably, Croyunfuranoid D（4） is identified as a rare 18,19-dinor-clerodane diterpenoid. Additionally, the structure of a previously reported diterpenoid, crotonyunnan B, was *** isolated compounds were evaluated for their inhibitory activities on nitric oxide（NO） production in LPS-induced RAW 264.7 macrophages. Among them, compounds 5 and 6 demonstrated significant inhibitory effects, with IC50values of 20.33 ± 2.31 and 22.80 ±1.31 μmol·L-1, respectively.
