Synthesis and biological evaluation of 5-substituted derivatives of benzimidazole
(Serbian Chemical Soc, Belgrade, 2014)
A series of eight novel 5-substituted derivatives of benzimidazole was synthesized by condensation of the corresponding diamine with ethyl 4-[4-(2-chlorophenyl)piperazin-1-yl]butanoate in refluxing 4 M hydrochloric acid. ...
The molecular properties of nitrobenzanthrone isomers and their mutagenic activities
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
The mutagenic activity of five mono-substituted nitrobenzanthrones (NBA) has been determined in the Ames assay (Takamura-Enya et al., 2006). In the present study, a theoretical investigation of the electronic properties ...
Formic Acid Oxidation at Platinum-Bismuth Clusters
(Electrochemical Soc Inc, Pennington, 2014)
Formic acid oxidation was studied on platinum-bismuth deposits on glassy carbon (GC) substrate. The catalysts of equimolar ratio were prepared by potentiostatic deposition using chronocoulometry. Bimetallic structures ...
Dose-dependent survival of K562 cells subjected to irradiation, time course of endogenous enzyme activity and protective effect of applied superoxide dismutase
(Zerbinis Publications, 2014)
Purpose: Irradiation-generated reactive species are proven to affect the cell survival and antioxidant enzyme levels. Radioresistance is a phenomenon which includes many cell mechanisms and signaling pathways. Superoxide ...
Parallel Water/Aromatic Interactions of Non-Coordinated and Coordinated Water
(Wiley-V C H Verlag Gmbh, Weinheim, 2014)
The parallel interactions of non-coordinated and coordinated water molecules with an aromatic ring were studied by analyzing data in the Cambridge structural database (CSD) and by using quantum chemical calculations. The ...
Nanoplasmonic chemical sensors
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
This work considers nanoplasmonic structures applicable in chemical and biological sensing. It offers a possible classification of these structures and an overview of the state-of-the-art sensing schemes that utilize them. ...
Comparative analysis of the polarization and morphological characteristics of electrochemically produced powder forms of the intermediate metals
(Macedonian Journal of Chemistry and Chemical Engineering, 2014)
The polarization and morphological characteristics of powder forms of the group of the intermediate metals were examined by the analysis of silver and copper electrodeposition processes at high overpotentials. The pine-like ...
New Pseudoguaiane Derivatives from Inula aschersoniana Janka var. aschersoniana
(Natural Products Inc, Westerville, 2014)
The aerial parts of Inula aschersoniana Janka var. aschersoniana afforded parthenolide, diepoxycostunolide, inusoniolide, chrysosplenol C and four new pseudoguaiane-type sesquiterpenoids. Their structures were determined ...
