(Elsevier, 2020)In this work, we present a solid silicon substrate functionalized with modified beta-cyclodextrin monolayers as an optimal surface for organic contaminant uptake. The inclusion and capture of three potential pollutants, ...
-
(Sociedade Brasileira de Quimica, 2009)An apparatus which allows the direct measurement of the antioxidant capacity of volatiles compounds emitted from some herbs and culinary spices is described. The device comprises: a sample chamber, a mixing chamber, a pump ...
-
(Springer New York LLC, 2018)© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. Hydroxyl radical reduction and peroxide bond breaking in hydrogen peroxide are reactions involved in various processes such as the Fenton reaction, which has ...
-
(Scholars Research Library, 2016)An analysis of the relationships between electronic structure and the inhibition of the kinase activity of VEGFR-2 was carried out for a series of 1-(4-((2-oxoindolin-3-ylidene)amino)phenyl)-3-arylureas. A similar study ...
-
(Research Journal of Pharmaceutical, Biological and Chemical Sciences, 2016)Allelopathic effects of a chemical compound strongly depends on the target species, dose or concentration employed, structure of the molecule and physical properties, such as water solubility, lipophilicity and others. In ...
-
(John Wiley and Sons Inc., 2009)A theoretical study of the electronic structure of the first members of the alkali metal atomic clusters series Lin to Csn (n = 2-8) has been done. The geometries of some isomers of the neutral, positive, and negative ...
-
(1990)The relative thermodynamic stabilities of several ion-pair structures, including intimate and solvent-separated forms, in solution have been studied for the allyl+/F- and allyl-/Li+ model systems. The electrostatic part ...
-
(Scholars Research Library, 2016)A Density Functional Theory study was carried out to find relationships between the electronic/molecular structure of a group of pyrazalone-quinazolone hybrids and their inhibition of human 4-hydroxyphenylpyruvate dioxygenase ...
-
(Sociedad Chilena de Química, 2007-05-02)We present the results of a quantum chemical study of the relationship between the electronic-conformational structure of a group of thiazolidenebenzenesulfo namide derivatives (TBS) and their Immunodeficiency Type 1 Virus ...

-
(2005)The reaction mechanism associated with the Bergman cyclization of the (Z)-hexa-1,5-diyne-3-ene to render p-benzyne has been analyzed by means of a combined use of the electron localization function (ELF) and the catastrophe ...
-
(American Chemical Society, 2003)In this paper we describe a method to obtain estimates of the relative nucleophilicity for a series of neutral and charged electron donors from their solution phase ionization potential (Is). The relationship between ...

(Elsevier, 1990)The relative thermodynamic stabilities of several ion-pair structures, including intimate and solvent-separated forms, in solution have been studied for the allyl +/F- and allyl- /Li + model systems. The electrostatic ...
-
A Tomato Tocopherol-Binding Protein Sheds Light on Intracellular α-Tocopherol Metabolism in Plants (NLM (Medline), 2018)Tocopherols are non-polar compounds synthesized in the plastids, which function as major antioxidants of the plant cells and are essential in the human diet. Both the intermediates and final products of the tocopherol ...
-
(Taylor & Francis, 2016)We obtain sufficient conditions ensuring the topological and strong topological equivalence of two perturbed difference systems whose linear part has a property of generalized exponential dichotomy. When the exponential ...

-
(Elsevier Science Ltd., 2003-03-12)Abstract—A simple method for the preparation of homochiral ring-substituted 1-aryl-2-aminopropanones 2 (‘cathinones’) is described, involving initial Friedel–Crafts acylation of aromatics with (S)- or (R)-N-trifluoroacetylalanyl ...
-
(1995)The synthesis, characterization and the reversible interaction with oxygen of a Cu(I)-mercaptoethylamine complex (I) in aqueous solution and room temperature is reported. As a result of the interaction with oxygen a violet ...
-
(University of Tehran., 2003-09-06)We present here the results of a formal structure-property relationship study carried out for 1 CB - and 2 CB -mediated inhibition of adenylyl cyclase (ADC) by a group of classical cannabinoid derivatives. The wave ...
