the aim of this research is preparation of sno2 nanowires by means of thermal chemical reaction vapor transport deposition (tcrvtd) method from sno powders. the morphology, chemical composition and microstructure properties of the nanowires are characterized using field emission scanning electron microscope (fe-sem), eds, and xrd. the xrd diffraction patterns reveal that the sno2 nanowires have...

Introduction: The mechanism of action and metabolism of clozapine, a complex drug used in psychopharmacology, is not completely understood. The effects of this compound in human body are related to some interactions with serotonin and dopamine neurotransmitter receptors. To further elucidate the mechanism of action and to support ongoing drug metabolism studies, [14C] clozapine with suita...

Isophorone is a technically important compound used as high-boiling-point solvent for coatings, adhesives, etc., and it starting material various valuable compounds, including isophorone diisocyanate, precursor polyurethanes. For over 80 years, has been synthesized via base-catalyzed self-condensation of acetone. This reaction complex mechanism with numerous possible steps the formation isophor...

A new tris-chelate Cd(II) complex, [Cd(DADMBTZ)3](ClO3)2 has been successfully synthesized and characterized by IR, 1H, 13C NMR spectroscopy, elemental analysis and single crystal X-ray determination. The thermal behavior, UV-Vis and fluorescence spectra of compound were studied. In reaction with DADMBTZ, Cadmium (II) forms a tris-chelate complex with nearly C3 symmetry for coordination polyhed...

The double Reformatsky reaction, tandem addition of two molecules of zinc alkanoate to a carbonyl compound, and its synthetic application to a series of δ-hydroxy-β-ketoesters has been developed. The key to accelerate the double Reformatsky reaction is considered to be a complex-induced proximity effect of the in situ generated zinc alkoxide coordinated with the pyridyl group of the substrate o...

The article analyzes the role of presupposition in the compound-complex sentence. The authors examine the types of presuppositions and minimal compound-complex sentence as a field of presuppositions action. The analysis of these types of sentences by the material of the English language shows that several kinds of presuppositions are realized in them – contact or distant, - developing in the re...

reaction of aryl methyl ketone with isatin in the presence of a base afforded 2- arylquinoline-4-carboxylic acid (3). reaction of diazomethane with compound 3 yielded the ester 4. compound 5 was prepared from the reaction of n, n'-dialkylethyl (or propyl) arnine with 4. addition of hydrazine hydrate to compound 4a gave 2- (2- pyridyl) quinoline-4-carboxylic acid hydrazide (6). reaction of ...

Background and Aims: Herpes simplex virus type 1 (HSV-1) belonging to herpes viridae family is a normal human pathogen with benign lesions in immunocompromised patients which creates serious problems. Acyclovir is used to treat herpetic infections. Because of developing drug-resistant strains, the use of medicinal plants and their related compounds with fewer side effects is considered for the ...
