1.Cytotoxic sesquiterpene lactones from Eupatorium lindleyanum.
Huo J;Yang SP;Ding J;Yue JM J Nat Prod. 2004 Sep;67(9):1470-5.
Ten new guaiane type sesquiterpene lactones, namely, eupalinilides A-J (1-10), as well as nine known compounds, eupachinilide C (11), eupachifolin D (12), eupachinilide E (13), 2alpha-hydroxyeupatolide (14), 3-deacetyleupalinin A (15), heliangine (16), 8beta-tigloyloxy-2,3-seco-6betaH,7alphaH-helianga-4Z,11(13)-diene-3,10beta;6, 12-diolid-2-oic acid (17), 8beta-(4'-hydroxytigloyloxy)-3beta,14-dihydroxy-6betaH,7alphaH-germacra-1(10)Z,4Z,11(13)-trien-6,12-olide (18), and 8beta-tigloyloxy-3beta,14-dihydroxy-6betaH,7alphaH-germacra-1(10)Z,4E,11(13)-trien-6,12-olide (19), were isolated from the whole plant of Eupatorium lindleyanum. Eupalinilides B (2), C (3), E (5), F (6), and I (9) have been tested for cytotoxicity against P-388 and A-549 tumor cell lines. The results showed that eupalinilides B (2) and E (5) demonstrated potent cytotoxicity. The structures of these compounds were determined by spectroscopic methods including 1D and 2D NMR spectra.
2.Heliangin inhibited lipopolysaccharide-induced inflammation through signaling NF-κB pathway on LPS-induced RAW 264.7 cells.
Lu X;Min L;Wei J;Gou H;Bao Z;Wang J;Wang Z;Huang Y;An B Biomed Pharmacother. 2017 Apr;88:102-108. doi: 10.1016/j.biopha.2017.01.041. Epub 2017 Jan 15.
The heliangin is a natural agent mainly isolated from Helianthus tuberosus L. (Asteraceae). In order to investigate the anti-inflammatory effect of heliangin, several typical models in vivo and in vitro were performed. The RAW264.7 mouse macrophages cells were employed in vitro and dexamethasone were conducted as positive. The cytotoxicity results of heliangin on RAW 264.7 cells provided the safety in vitro for further study. The mRNA of TNF-α, IL-6, iNOS and COX-2 were degraded under heliangin exposure in LPS-stimulated RAW 264.7 cells. The protein expression of iNOS, COX-2 were decreased via heliangin exposure in a dose-dependent manner. Heliangin inhibited TNF-α, NO, IL-6 and PGE;2; expression levels in macrophage cells lysate. The immunocytochemistry assay showed the fluorescence image of heliangin treatment intercepted the p65 translocation process from outside to inside of nuclei triggered by LPS. Moreover, we founded that MAPK and NF-κB signaling pathway play important roles in heliangin's activity on RAW264.7 cells. Secondly, the acute toxic study results of heliangin manifested the safety in vivo. Heliangin exerted anti-inflammation effect in a xylene-induced ear swelling in BALB/C mice and carrageenan-induced paw edema model in SD rats.
3.Cytotoxic sesquiterpene lactones from Eupatorium kiirunense, a coastal plant of Taiwan.
Shen YC;Lo KL;Kuo YH;Khalil AT J Nat Prod. 2005 May;68(5):745-50.
Phytochemical investigation of Eupatorium kiirunense has resulted in the isolation of eight new sesquiterpene lactones, constituted by five germacranolides, eupakirunsins A-E (1-5), and three heliangolides, eupaheliangolide A (6), 15-acetoxyheliangin (7), and 3-epi-heliangin (8), in addition to the known heliangin (9) and 8,10-epoxy-9-acetoxythymol angelate (10). The structures of the new compounds were established through detailed analysis of their spectroscopic data. Compounds 6, 8, and 9 exhibited cytotoxicity against human oral epidermoid (KB), cervical epitheloid (Hela), and liver (hepa59T/VGH) carcinoma cells.
