Novel 1,3,4-thiadiazole-chalcone hybrids containing catechol moiety: synthesis, antioxidant activity, cytotoxicity and DNA interaction studies
(Royal Soc Chemistry, Cambridge, 2018)
Hybrid compounds that combine the 1,3,4-thiadiazole-containing catechol moiety with a chalcone motif were synthesized and examined for their antioxidant activity, cytotoxicity, and DNA-binding activity. A series of thirteen ...
Synthesis, dopamine D-2 receptor binding studies and docking analysis of 5-[3-(4-arylpiperazin-1-yl)propyl]-1H-benzimidazole, 5-[2-(4-arylpiperazin-1-yl)ethoxy]-1H-benzimidazole and their analogs
(Editions Scientifiques Medicales Elsevier, Paris, 2005)
5-[3-(4-Arylpiperazin-1-yl)propyl]-1H-benzimidazoles and 5-[2-(4-aryipiperazin-1-yl)ethoxy]-1H-benzimidazoles were synthesized and their affinity for the D-1, D-2 and 5-HT1A, receptors examined. They expressed a rather ...
Assessment of Degradation of Sulfonylurea Herbicides in Water by Chlorine Dioxide
(Springer International Publishing Ag, Cham, 2018)
The degradation of two sulfonylurea herbicides, nicosulfuron and thifensulfuron methyl in water by chlorine dioxide, was studied for the first time in this paper. In order to examine the optimal parameters for degradation ...
Anti-human albumin monoclonal antibody immobilized on EDC-NHS functionalized carboxylic graphene/AuNPs composite as promising electrochemical HSA immunosensor
(Elsevier, 2020)
Diagnosis and treatment of some important diseased and metabolic disorders is based on successful detection of albumin. In this work, we aim to develop a simple immunosensor for the detection of human serum albumin in ...
Photochemically induced mercuric oxide - iodine oxidation of some unsaturated steroid compounds
(Pergamon, 1994)
Photochemically induced HgO/I2 oxidation of cholest-5-en-3α-ol (6) and cholest-5-en-3β-ol (7) afforded (Scheme 3) products arising from the corresponding alkoxy radicals (12, 13 and 14a,b) and from attack of the I2O ...
Free-radical oxidative transformations of androst-4-ene-3β,9α,17β-triol 3,17-diacetate
(Tetrahedron, 1988)
The oxidation of androst-4-ene-3β,9α,17β-triol 3,17-diacetate (2) with lead tetraacetate resulted mainly In β-fragmentation of the C(9)-C(10) bond to give a mixture of 10α- and 10β-acetoxy-Δ4-unsaturated 9,10-seco-steroidal ...
A Base Promoted Cyclization of N-Propargylaminopyridines. Synthesis of Imidazo[1,2-a]pyridine Derivatives
(American Chemical Society (ACS), 2011)
A base promoted cyclization of the protected N-propargylaminopyridines was shown to be an efficient method for the preparation of imidazo[1,2-a] pyridine derivatives. The reactions were carried out with a small excess of ...

(Journal of Basic Microbiology, 2009)
An extracellular lipase from Pseudomonas aeruginosa ATCC 27853 has been purified and its enzymatic characteristics were determined. According to SDS-PAGE and gel filtration molecular mass estimated to be 30 kDa, what ...
Catalysis of hydrogen evolution on different Pd/Au(111) nanostructures in alkaline solution
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Hydrogen evolution reaction (HER) was studied on Pd/Au(1 1 1) bimetallic surfaces in alkaline solution. Au(1 1 1) was modified by palladium nanoislands spontaneously deposited using PdSO4 center dot 2H(2)O and PdCl2 salts. ...
