Abstract
Extracts from Securidaca longipedunculata showed antiplasmodial activities against reference clones and clinical isolates using SYBR Green I method. A new benzophenone, 2,3,4,5-tetramethoxybenzophenone (1) was isolated and characterized along with seven known compounds: 4-hydroxy-2,3-dimethoxybenzophenone (2); 3-hydroxy-5-methoxybiphenyl (3), methyl-2-hydroxy-6-methoxybenzoate (4), benzyl-2-hydroxy-6-methoxybenzoate (5), 2-hydroxy-6-methoxybenzoic acid (6), 2,4,5-trimethoxybenzophenone (7) and 2-methoxy-3,4-methylenedioxybenzophenone (8). Compounds 1 and 2 showed ex vivo antiplasmodial activities (IC50 28.8 μM and 18.6 μM, respectively); while 5 and 8 showed in vivo activities (IC50 19.7 μM and 14.5 μM, respectively) against D6 strain. In a cytotoxicity assay, all the extracts (with an exception of the MeOH extract of the leaves) and pure compounds were not toxic to the normal LO2 and BEAS cell-lines, while the methanol roots extract (IC50 66.4 µg/mL against A549, and 77.4 µg/mL against HepG2), compounds 6 (IC50 22.2 µM against A549) and 7 (IC50 45.2 µM against HepG2) were weakly active against cancerous cell-lines.

Xanthones from Securidaca inappendiculata exert significant therapeutic efficacy on adjuvant-induced arthritis in mice. Inflammation 2015; 37:908-16.

Abstract
The study was designed to investigate effects of the xanthones from Securidaca inappendiculata on adjuvant-induced arthritis (AA) mice in vivo. Arthritis severity was evaluated by arthritic score, body weight loss, paw circumference, histological changes and hyperplasia of lymphatic tissues. Plasma samples were collected for estimation of interleukin-1 (IL-1), tumor necrosis factor alpha (TNF-α), monocyte chemotactic protein 1 (MCP-1) and vascular endothelial growth factor (VEGF) using enzyme-linked immunosorbent assay method. The levels of glutathione (GSH), malondialdehyde (MDA), N-acetyl glucosaminidase (NAG) and sialic acid (SA) in liver were assessed by colorimetric method. Xanthones significantly ameliorated the severity of AA indicated by the physical parameters changes, and reverted the abnormal changes of MDA, GSH, NAG and SA in liver. Levels of IL-1, TNF-α, MCP-1 and VEGF reduced dramatically meanwhile. The effects of xanthones on AA were the outcome of the multitargets activities, and probably associated with NF-κB signaling pathway.

Abstract
Natural benzophenones are a class of compounds with more than 300 members, mainly in the Clusiaceae family. We review key benzophenones, and provide an in-depth discussion of their great structural diversity and biological activity.
