Tang, Qing; Luo, Ding; Lin, Ding-Chai; Wang, Wen-Zhi; Li, Can-Jie; Zhuo, Xue-Fang; Wu, Zhong-Nan; Zhang, Yu-Bo; Wang, Guo-Cai; Li, Yao-Lan published the artcile< Five matrine-type alkaloids from Sophora tonkinensis>, Safety of (41S,7aR,13aR,13bR)-Dodecahydro-1H-dipyrido[2,1-f:3′,2′,1′-ij][1,6]naphthyridin-10(41H)-one, the main research area is Sophora root 1213 dehydrosophoridine isosophocarpine sophoridine; 12,13-dehydrosophoridine; 13β-hydroxymatrine; Anti-inflammatory activity; Matrine-type alkaloid; Sophora tonkinensis.
Five matrine-type alkaloids (1-5) including two new compounds (1 and 3) and a new natural product (2) were isolated from the roots of Sophora tonkinesis. Their structures were identified by extensive spectroscopic anal. (UV, IR, HRESIMS and NMR). The absolute configurations of 2 and 3 were determined by X-ray diffraction. Compounds 1-5 were evaluated their activity against inflammatory cytokines TNF-α and IL-6 levels on LPS-induced RAW 264.7 macrophages, and compound 1 showed the most significant activity, potent than that of matrine, the representative ingredient from Sophora plants.
