(Elsevier Science ltd., 1995)Bioactivity guided fractionation of the dichloromethane extract from Psoralea glandulosa yielded the isolation of a diasteromeric mixture of cyclobakuchiols A and B as possible anti-inflammatory active compounds.
-
(2012)The knowledge of the host-guest complexes using cyclodextrins (CDs) has prompted an increase in the development of new formulations. The capacity of these organic host structures of including guest within their hydrophobic ...
-
(MDPI, 2021)In drug delivery, one widely used way of overcoming the biopharmaceutical problems present in several active pharmaceutical ingredients, such as poor aqueous solubility, early instability, and low bioavailability, is the ...
-
(SPRINGER/PLENUM PUBLISHERS, 2011-04)The slightly water-soluble flavonoid kaempferol (KAE) and its inclusion complexes with beta-cyclodextrin (beta CD), hydroxypropyl-beta-cyclodextrin (HP beta CD) or heptakis-2,6-O-dimethyl-beta-cyclodextrin (DM beta CD) ...
-
(Elsevier, 2018)A novel series of cyrhetrenyl (3a-4a) and ferrocenyl (3b-4b) Schiff bases were synthesized through a condensation reaction, between the known 4-ferrocenylaniline (2b) or the unreported 4-cyhretrenylaniline (2a) with 4-or ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2000-09)Carbon paste electrodes were modified with cytochrome c reductase enzyme. The behavior of the electrodes was characterized by cyclic voltammetry. The cytochrome c reduction was investigated both on the enzyme modified ...
-
(Elsevier B.V., 2017)Two new organometallic compounds with the general formula [Ru(eta(6)-anethole)(en)(MPF6, where X = Br (5) or I (6) and en = ethylenediamine, were synthesized and fully characterized using standard techniques (NMR, MS and ...
-
(American Chemical Society, 2020)Opioids are arguably one of the most important pharmacologic classes, mainly due to their rich history, their useful and potent analgesic effects, and also, just as importantly, their “Dark Side”, constituted by their ...
-
(1987)The deactivation of a number of excited polycyclic aromatic hydrocarbons by copper(II), cobalt(II), nickle(II) and chromium(III) in ethanol-water (1:1 by volume) has been investigated. In spite of the fact that most of the ...
-
(Pergamon Press Ltd, 1982)During 1 yr, CO2-C losses from 7 agricultural soils containing 0,5-1,5% organic C ranged from 70 to 243 mg 100g-1 while losses from three allophanic soils containing 4,9-8,9% organic C varied from 92 to 191 mg. Losses as ...
-
(1991)Kinetic and product studies indicate that the title compound decomposes in aqueous solutions to give 5-nitro-2-aminophenol with the intermediacy of N-(2-hydroxy-4-nitrophenyl)carbamic acid. © 1991.
-
(2016)The uptake of triclosan (TCS) and its metabolite methyl-triclosan (MTCS) by plants is poorly discussed in the current literature. The aim of this research was to analyze the extent of absorption of these compounds by the ...
-
(Elsevier, 2015)Diabetic cardiomyopathy (DCM) is a common consequence of longstanding type 2 diabetes mellitus (T2DM) and encompasses structural, morphological, functional, and metabolic abnormalities in the heart.Myocardial energy metabolism ...

Defined Single-Gene and Multi-Gene Deletion Mutant Collections in Salmonella enterica sv Typhimurium (PLOS One, 2014)We constructed two collections of targeted single gene deletion (SGD) mutants and two collections of targeted multi-gene deletion (MGD) mutants in Salmonella enterica sv Typhimurium 14028s. The SGD mutant collections ...
-
(Springer Verlag, 2018)© 2018, Springer-Verlag GmbH Germany, part of Springer Nature. The intensive use of insecticides such as chlorpyrifos (CPF) and diazinon (DZN) in the agricultural activities worldwide has produced contamination of soils ...
