Journal ArticleDOI
TL;DR: These compounds are the first derivatives of magic-size CdSe nanoclusters to be isolated in purity and characterized by elemental analysis, IR spectroscopy, UV-vis spectroscopic, TEM, and low-angle XRD.
Abstract: Four [(CdSe)13(RNH2)13] derivatives (R = n-propyl, n-pentyl, n-octyl, and oleyl) are prepared by reaction of Cd(OAc)2·2H2O and selenourea in the corresponding primary-amine solvent. Nanoclusters gr...

Journal ArticleDOI
TL;DR: In this article, a one-pot synthesis of three new ferrocene incorporated selenoureas was reported, namely; 1-(2-fluorobenzoyl)-3-(4-ferrocenyl-3-methylphenyl)selenourea (MeP2F), 1-(3-fluorsenoyl), 3-methyl-4-fricenyl aniline (3-M-Aniline), and MeP4F, by the reaction of corresponding carboxylic acid chlorides with potassium se

Journal ArticleDOI
TL;DR: In this article, the authors have reported synthesis, chemical characterization (with single crystal XRD, elemental analysis, FTIR and multinuclear NMR spectroscopy), DNA binding and antioxidant activities (1,1-diphenyl-2-picrylhydrazyl scavenging) of 1-(2-methylbenzoyl)-3-(3-ferrocenylphenyl)selenourea (MOT).

Journal ArticleDOI
TL;DR: Low biopersistence in the human body may be anticipated after establishing relations between biomimetic retention factors and lipophilicity, the effect of the presence of reduced glutathione to retention, as well as to determine the oxidation potential by means of cyclic voltammetry.

TL;DR: Bis(4,6-dimethylpyrimidin-2-yl) diselenide, a new representative of dihetaryl diselsenides, was obtained by successively treating selenourea with hydrochloric acid, acetylacetone, potassium hydroxide, and the system iodine.
Abstract: Bis(4,6-dimethylpyrimidin-2-yl) diselenide, a new representative of dihetaryl diselenides, was obtained by successively treating selenourea with hydrochloric acid, acetylacetone, potassium hydroxide, and the system iodine—potassium iodide. The unusual planar trans-conformation of this compound (X-ray diffraction data) is stabilized by intramolecular attractive nonvalent Se…N interactions (Se…N, 2.926(1) A) and stacking of the π-systems of the aromatic heterocycles (the centers of the pyrimidine rings are spaced apart at 3.365(2) A). The energy parameters of the factors that make the molecular structure flattened were estimated by quantum chemical DFT calculations.

TL;DR: A simple route for the synthesis of neoglycosylated amino acids possessing a selenourea moiety is described in this article, where the coupling of �-isoselenocyanato esters or Cbz/Boc-amino alkyl isoselenocalyanates with peracetyl/benzoylated glucosylamine at ambient temperature led to insert selenoupine as a linker.
Abstract: A simple route for the synthesis of a new class of neoglycosylated amino acids possessing a selenourea moiety is described. The coupling of �-isoselenocyanato esters or Cbz/Boc-amino alkyl isoselenocyanates with peracetyl/benzoylated glucosylamine at ambient temperature led to insert selenourea as a linker. All the compounds prepared have been isolated as analytically pure ones, and characterized by 1 H, 13 C and 77 Se NMR, and mass spectroscopy.
