Molecular orbital studies on pericyclic reactions of cinnamyl xanthates in beta-cyclodextrin cavities.
The solid beta-cyclodextrin (beta-CyD) complex of O-cinnamyl S-methyl dithiocarbonates (xanthate, 1a), upon heating at 45 degrees C, underwent asymmetric [3,31-sigmatropic rearrangement to give the optically S-(1-phenylallyl) S-methyl dithiocarbonate (2a) with 60% ee. Heating the beta-CyD complex of 2a at 120 degrees C caused extrusion of COS to give cinnamyl methyl sulfide (3a) in high yield. ...
متن کاملMetal (II) Complexes of Fluconazole: Thermal, XRD and Cytotoxicity Studies
We report thermal, X-ray diffraction (XRD) and cytotoxicity studies of complexes of fluconazole (FCZ) with Cu (II), Fe(II), Cd(II), Co(II), Ni(II), and Mn(II). From XRD measurements, FCZ and its metal complexes were identified as polycrystalline. Marked differences in the X-ray patterns of drug and its metal complexes revealed that the complexes are indeed different compounds and not just the m...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

متن کاملSpeciation Studies of Metal Ions in Environmental and Biological Media Using Supported Liquid Membrane Extraction
In ecological risk assessment for chemical pollutants, it is important to quantify the concentrations of freely dissolved substances in aqueous samples for approximate characterization of the bioavailable fraction. Such measurements are important because the concentration and toxicity of a chemical in an organism’s body are linked to the bioavailable fraction and its chemical form within the su...
