2008 NOV 17 - (VerticalNews.com) -- According to a study from South Africa, "Structural properties of selected derivatised cyclodextrins (CDs), gleaned from single crystal X-ray studies, are described with reference to the effects on molecular conformation and inclusion ability accompanying their formation from the corresponding native CDs."

  "Species of interest include several acylated and methylated CDs as well as their inclusion complexes with drug guest molecules. As a representative example of an inclusion complex in this category for which full structural and thermal characterization has recently been achieved, that between permethylated alpha-CD and the antihypertensive metoprolol is presented," wrote M.R. Caira and colleagues, University of Cape Town ...read more

  2008 NOV 17 - (VerticalNews.com) -- "The studied compounds were prepared by decyclization of oxazoline N-acilaminoacid under action of methanol, ethanol propanol and isopropanol. The temperature dependence of the electrical conductivity and Seebeck coefficient of the respective compounds were investigated using thin film samples (d = 0.40 mu m - 2.35 mu m), deposited from dimethylformamide onto glass substrates," investigators in Iasi, Romania report ...read more

  2008 NOV 17 - (VerticalNews.com) -- "The metal-amino acids complexes have different applications as antibacterial agents against Staphylococcus aureus, Streptococcus pyogene, Escherichia coli and also as nutritional supplements. The [Cu(L)(2)]center dot H2O (1), [Co(L)(2) ]center dot 2H(2)O (2) and [Zn(L)(2)]center dot H2O (3) complexes with hystidine (L) as ligand, were synthesized in water solution and analyzed by means of elemental analysis, atomic absorption, FT-IR, UV-VIS and EPR spectroscopies," scientists writing in the Journal of Optoelectronics and Advanced Materials report ...read more
