Heat was employed to coat crystalline goethite onto a quartz sand surface so that the adsorbent properties of the coating could be utilized. The adsorption characteristics of cadmium and humic acid onto goethite-coated sand were examined. Results show that the goethite-coated sand surface had a higher specific surface area and more mesopores than the(More)
In this study, we investigated the effects of 95% ethanol (FS-t1), 50% ethanol (FS-t2) and water (FS-w) extracts of Forsythia suspense Vahl (Oleaceae) on the production of regulated on activation, normal T cell expressed and secreted (RANTES) and macrophage chemotactic protein-1 (MCP-1) by influenza A virus (H1N1)-infected human bronchial epithelial cell(More)
The antiinflammatory activities of the isolated flavonoids, including cycloartomunin (1), cyclomorusin (2), dihydrocycloartomunin (3), dihydroisocycloartomunin (4), cudraflavone A (5), cyclocommunin (6), and artomunoxanthone (7), and cycloheterohyllin (8), artonins A (9) and B (10), artocarpanone (11), artocarpanone A (12), and heteroflavanones A (13), B(More)
In an effort to develop novel antitumor or chemopreventive agents, a series of 2',5'-dimethoxychalcone derivatives were prepared by Claisen-Schmidt condensation of appropriate acetophenones with suitable aromatic aldehyde. In vitro screening revealed low micromolar activity (IC(50)) against several human cancer lines. Activity in MCF-7 cells correlated with(More)
We attempted to clarify the role of Ca2+ in cell death caused by beta-amyloid protein (Abeta) and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in SK-N-SH neuroblastoma, respectively. Two insults both reduced cell viability in a concentration-dependent manner and induced equal cytotoxicity in the presence of 20 microM Abeta and 0.4 mM MPTP for 72 h,(More)
Twenty-three ursolic acid (1) derivatives 2-24 including nine new 1 derivatives 5, 7-11, 20-22 were synthesized and evaluated for cytotoxicities against NTUB1 cells (human bladder cancer cell line). Compounds 5 and 17 with an isopropyl ester moiety at C-17-COOH and a succinyl moiety at C-3-OH showed potent inhibitory effect on growth of NTUB1 cells.(More)
Twenty 18beta-glycyrrhetic acid (18beta-GA) derivatives 2-21 including 13 new 18beta-GA derivatives were synthesized and evaluated as anti-inflammatory and antioxidant agents. Compounds 7 and 20 with a 3,4-seco-structure and compound 6 with a lactone moiety showed potent inhibitory effect on superoxide anion generation in rat neutrophils response to fMLP/CB(More)
The accumulation of inflammatory cells in the infective sites has been reported to play a crucial role in the progression of chronic inflammation and multiple sclerosis after viral infection. In the present study, nine ethanol extracts of Forsythia suspensa Vahl. (Oleaceae), Lonicera japonica Thunb. (Caprifoliaceae), Isatis indigotica Fort. (Cruciferae),(More)
A new phloroglucinol, garcinielliptone HF ( 1), possessing an unprecedented skeleton, and the tautomeric pair of garcinielliptone FC ( 2/ 2a) were isolated from the heartwood and pericarp of Garcinia subelliptica, respectively. Their structures, including relative configurations, were elucidated by means of spectroscopic methods. The ability of compounds 1(More)
Deep ocean water (DOW) has, in previous studies, been found to be a novel anti-obesity drink and useful in raising Monascus-produced monascin and ankaflavin levels. This may resolve the limited anti-obesity ability of red mold dioscorea (RMD) known as the Monascus purpureus-fermented Disocorea batatas. This study aims to compare the anti-obesity effect of(More)
