(WILEY-BLACKWELL PUBLISHING, INC, 2009-02)The title molecule, C14H14O3, contains two fused six-membered carbon rings with keto groups at positions 1, 4 and 5 and a gem-diethyl group at position 8. The molecule is close to planar (maximum deviation = 0.044 angstrom), ...
-
(BLACKWELL PUBLISHING, 2008-07)In the title molecule, C16H16O3, the ring system is planar and an intramolecular hydrogen bond is present. The molecular packing is dominated by an intermolecular hydrogen bond and by pi-stacking interactions [interplanar ...
-
(MDPI AG, 2019)© 2019 by the authors.Intramolecular hydrogen bond (IMHB) interactions have attracted considerable attention due to their central role in molecular structure, chemical reactivity, and interactions of biologically active ...
-
(Taylor and Francis Ltd., 2018)Searching for a lubricant to be used in articular bone joints, a new nematic liquid crystal (NLC) was characterised. It is formed by dissolving tetradecyltrimethyl ammonium bromide (TTAB), decanol (DeOH), sodium bromide ...
-
(Royal Soc Chemistry, 2015)In this work we present a study on the molecular structure and electrochemical behavior of a series of methoxylated 2'-hydroxychalcones, whose antitumor activity has been previously described. Cyclic voltammetry was used ...
-
(Royal Soc Chemistry, 2015)The effect of carbonyl groups in the ortho position with respect to a hydroxyl group on the electrochemical oxidation of hydroquinones in acetonitrile is studied. The electrochemical response of hydroquinone on a glassy ...
-
(Bentham Science Publishers B.V., 2015)© 2015, Bentham Science Publishers. Curcumin, a natural yellow polyphenol, is isolated from the herb Curcuma longa L. (turmeric), a member of the ginger family. It has been extensively studied due to their multiple ...
-
(MDPI, 2014)Intramolecular hydrogen bonds (IHBs) play a central role in the molecular structure, chemical reactivity and interactions of biologically active molecules. Here, we study the IHBs of seven related o-carbonyl hydroquinones ...
-
(Sociedad Chilena de Quimica, 2012)4,4-Dimethyl-5,8-dihydroanthracene-1,9,10(4H)-trione (Q1) and 9,10-Dihydroxy-4,4-dimethyl-5,8-dihydro-1 (4H)-anthracenone (Q2), two molecules that inhibit cancer cell respiration, were selectively deuterated and dissolved ...
-
(2014)A study about the oxidative coupling of some representative carbo-and heterocyclic non-symmetrical quinones with aryl-and alkylamines, was carried out comparing dichloromethane and water as reaction mediums. We found that ...
-
(Elsevier, 2013)Tumor cells present a known metabolic reprogramming, which makes them more susceptible for a selective cellular death by modifying its mitochondrial bioenergetics. Anticancer action of the antioxidant 9,10- dihydroxy-4 ...
-
(Universidad de Chile, 2013-09)En esta tesis doctoral se estudió, en forma experimental y teórica, la reacción de acoplamiento oxidativo de las quinonas carbo- y heterocíclicas 2-metil-1,4-benzoquinona, 8,8-dimetilnaftalen-l,4,5(8H)-triona y el éster ...
-
(Universidad de ChileCyberDocs, 2011)Se sintetizó una serie de hidroquinonas tricíclicas, mediante reacciones Diels-Alder de quinonas bicíclicas con distintos dienos. Posteriormente, algunas de las hidroquinonas tricíclicas fueron oxidadas a las correspondientes ...
-
(Hindawi Limited, 2017)© 2017 Maximiliano Martínez-Cifuentes et al. The mandatory presence of a chlorine atom on the aromatic ring of 6-hydroxy-3-formyl angular chromones, on the respiration inhibition of mammary carcinoma mouse, is explained ...
