Radical, one-step approach to o-chlorophenyl thioethers from xanthates. A rapid access to vinylsilanes
(Amer Chemical Soc, Washington, 2008)
Xanthates have been readily converted into o-chlorophenyl thioethers using a one-step procedure conducted under radical conditions. In some selected cases, these aryl thioethers were successfully oxidized to the corresponding ...
Photophysical, electrochemical, and mesomorphic properties of a liquid-crystalline [60]fullerene-peralkylated ferrocene dyad
(Royal Soc Chemistry, Cambridge, 2008)
Two fullerene-peralkylated ferrocene derivatives were synthesized: (1) a liquid-crystalline dyad (compound 1) was obtained by introduction of nonamethyl ferrocene into a liquid-crystalline fullerene derivative and (2) a ...
Chemical stability of the peroxide bond enables diversified synthesis of potent tetraoxane Antimalarials
(Amer Chemical Soc, Washington, 2008)
The development of widespread drug resistance to chloroquine (CQ(a)) has resulted in severe health issues for countries in malaria endemic regions. The antimalarial properties of artemisinin 2 and of other peroxides, such ...
Simultaneous determination of some water-soluble vitamins and preservatives in multivitamin syrup by validated stability-indicating high-performance liquid chromatography method
(Elsevier Science Bv, Amsterdam, 2008)
HPLC stability-indicating method has been developed for the simultaneous determination of some water-soluble vitamins (ascorbic acid, thiamine hydrochloride, riboflavin-5'-phosphate sodium, pyridoxine hydrochloride, ...
Evaluation of antioxidant capacity of Allium ursinum L. volatile oil and its effect on membrane fluidity
(Elsevier Sci Ltd, Oxford, 2008)
A total of 20 components were identified in Allium ursinum volatile oil (AUVO) by GC-MS, and 10 of them are found for the first time in this plant species. The antioxidant capacity of AUVO was examined by beta-carotene-linoleic ...
Electrochemical bromination of peracetylated glycals
(Wiley-V C H Verlag Gmbh, Weinheim, 2008)
Bromination of glycals with tribromides formed in situ from bromine and different bromide salts in dichloromethane (DCM) or acetonitrile (AN) was found to give predominantly the products of anti addition of bromine from ...
New chimeric antimalarials with 4-aminoquinoline moiety linked to a tetraoxane skeleton
(Amer Chemical Soc, Washington, 2008)
The synthesis of the chimeric molecules consisting of two pharmacophores, tetraoxane and 7-chloro-4-aminoquinoline, is reported. The tetraoxanes 2, 4, and 8 show relatively potent in vitro antimalarial activities, with ...
A 3-fold "Butterfly Valve" in Command of the Encapsulation's Kinetic Stability. Molecular Baskets at Work
(Amer Chemical Soc, Washington, 2008)
Molecular basket 1, composed of a semirigid tris-norbornadiene framework and three revolving pyridine-based gates at the rim, has been built to "dynamically" enclose space and as such regulate molecular encapsulation. The ...
Removal of organically bound sulfur from oil shale by iron(III)-ion generated-regenerated from pyrite by the action of Acidithiobacillus ferrooxidans - Research on a model system
(Elsevier Science Bv, Amsterdam, 2008)
Oil shale is one of the alternative sources of hydrocarbon fuels ("synthetic petroleum") but is characterized by increased sulfur and nitrogen contents, which represent even greater ecological problems in its use compared ...
Quantification of the thaumatin-like kiwi allergen by a monoclonal antibody-based ELISA
(Wiley-Blackwell, Malden, 2008)
Thaumatin-like proteins (TLPs) have been established as a new family of fruit and pollen allergens. The aim of this study was to develop a two-site ELISA for the quantification of the thaumatin-like kiwi allergen (Act d ...
