Cholate-solubilized chick kidney mitochondria that 1-hydroxylated 25-hydroxyvitamin-D3 (25-OH-D3) upon reconstitution also produced 10-oxo-19-nor-25-OH-D3, which co-eluted with 1,25-dihydroxyvitamin D3 (1,25-(OH)2-D3) on normal phase high performance liquid chromatography (HPLC) with hexane:propanol-2 (9:1), the traditional chromatographic system for isolating 1,25-(OH)2-D3. The 10-oxo derivati...
Three dinuclear [Ln2H2OL(1)2(acac)2]·solvent (1, Ln = Gd, solvent = 2CH2Cl2; 2, Ln = Tb, no solvent; 3, Ln = Er, solvent = (C2H5)2O), and two tetranuclear lanthanide clusters [Ln4(μ3-OH)2L(2)2(acac)6]·2(solvent) (4, Ln = Tb, solvent = CH3OH; 5, Ln = Dy, solvent = CH3CN) were characterized in terms of structure, fluorescence and magnetism. The dinuclear lanthanide complexes were constructed by a...
The reaction between [V(IV)OSO(4)] and the tetradentate N(2)O(2)-donor Schiff base ligand, N,N-bis(o-hydroxybenzaldehyde)phenylenediamine (sal-HBPD), obtained by the condensation of salicylaldehyde and o-phenylenediamine in a molar ratio of 2 : 1 respectively, resulted in the formation of [V(IV)O(sal-HBPD)]. The molecular structure of [V(IV)O(sal-HBPD)] was determined by single crystal X-ray di...
In this article, we report on the facile and rapid synthesis of conjugation polymer poly(p-phenylenediamine) nanobelts (PNs) via room temperature chemical oxidation polymerization of p-phenylenediamine monomers by ammonium persulfate in aqueous medium. We further demonstrate the proof-of-concept that PNs can be used as an effective fluorescent sensing platform for nucleic acid detection for the...
The effects of phenylethylbiguanidide, decamethylenediguanidide, and octylguanidine have been studied with mung bean hypocotyl mitochondria (Phaseolus aureus var. Jumbo) supplied with malate, reduced nicotinamide adenine dinucleotide, succinate, or ascorbate-tetramethyl-p-phenylenediamine as substrates. The guanidines act as energy transfer inhibitors, all three inhibiting all three phosphoryla...
The metabolism of 2-acetylaminofluorene (AAF) as well as the activation of AAF to covalently bound and mutagenic intermediates were studied in isolated rat hepatocytes. The cell system readily formed oxidized, deacetylated, and conjugated AAF metabolites. Pretreatments of animals with the inducer beta-naphthoflavone led to increases in phenolic and conjugated as well as covalently protein-bound...
