A novel polyhydroxy compound with a linear carbon-chain, lingshuiol (1), had been isolated from the cultured marine dinoflagellate Amphidinium sp. Its structure was elucidated by extensive analysis of 2D NMR spectral data. Lingshuiol possessed a powerful cytotoxic activity against A-549 and HL-60 cells in vitro with the IC(50) of 0.21 and 0.23 microM,… (More)
A metal-organic nanotubular architecture was built from parallel-aligned single-walled nanotubes which interlink by means of micro3-bridged counterions, representing the first example of coordination nanotubes presumably generated from two-dimensional (2D) sheets.
It was found in the present study that combined use of fusidic acid (FA) and berberine chloride (BBR) offered an in vitro synergistic action against 7 of the 30 clinical methicillin-resistant Staphylococcus aureus (MRSA) strains, with a fractional inhibitory concentration (FIC) index ranging from 0.5 to 0.19. This synergistic effect was most pronounced on… (More)
Five new sesquiterpenes, named lingshuiolides A (1) and B (2), lingshuiperoxide (6), isodysetherin (10), and spirolingshuiolide (12), along with several known related analogues (7- 9, 11, and 13- 15), were isolated from the Hainan marine sponge Dysidea septosa. The structures of new compounds 1, 2, 6, 10, and 12 were determined by detailed analysis of 1D… (More)
Rare gas containing cations with general formula [Rg, B, 2F](+) have been investigated theoretically by second-order Mo̸ller-Plesset perturbation, coupled cluster, and complete active space self-consistent field levels of theory with correlation-consistent basis sets. Totally two types of minima, i.e., boron centered C(2) (v) symmetried RgBF(2) (+) (Rg =… (More)
One-pot solvothermal treatments of organonitriles, ammonia, and Cu(II) salts yielded Cu(I) and 3,5-disubstituted 1,2,4-triazolates. The organic triazolate components were derived from copper-mediated oxidative cycloaddition of nitriles and ammonia, in which a key intermediate 1,3,5-triazapentadienate was isolated as [Cu(II)(4-pytap)(2)] (4-Hpytap =… (More)
Coordination polymers have been emerging as a topical research field in crystal engineering, solid-state chemistry, and materials science. Considering the wide occurrence of structural and compositional diversity during self-assembly and crystallization, supramolecular isomerism represents an indication of composition control and structure prediction.… (More)
Two complexes, 2D [Cu(2)(CN)(2)(4-Hpcih)](n) and 3D [[Cu(2)(CN)(1.5)(4-pcih)].1.25H(2)O](n) (4-Hpcih = 4-pyridinecarbaldehyde isonicotinoyl hydrazone), were obtained using a synthetic approach of pH-induced formation of metalloligands, successfully demonstrating a strategy to increase structure dimensionality by tuning the number of ligand functional sites.
ETHNOPHARMACOLOGICAL RELEVANCE Tripterygium hypoglaucum (levl.) Hutch (Celastraceae) (THH) root is a traditional Chinese medicinal herb commonly used for treating autoimmune diseases and cancer. Alkaloid is one of the most bioactive components of THH extract. To evaluate the in vitro and in vivo antitumor properties of the total alkaloids of THH (THHta). … (More)
