    • 8,8-Diethyl-1,4,5,8-tetrahydronaphthalene-1,4,5-trione 
      Vega, Andrés; Ramírez Rodríguez, Oney; Martínez Cifuentes, Maximiliano; Ibáñez, Andrés; Araya Maturana, Ramiro (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), ...
    • 9,10-dihydroxy-4,4-dimethyl-5,8-dihydroanthracen-1(4H)-one 
      Ramírez Rodríguez, Oney; Martínez Cifuentes, Maximiliano; Ibáñez, A.; Vega, Andrés; Araya Maturana, Ramiro (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 ...
    • Electrochemical characterization of hydroquinone derivatives with different substituents in acetonitrile 
      Salazar, Ricardo; Vidal, Jorge; Martínez Cifuentes, Maximiliano; Araya Maturana, Ramiro; Ramírez Rodríguez, Oney (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 ...
    • Heterocyclic curcumin derivatives of pharmacological interest: Recent progress 
      Martínez Cifuentes, Maximiliano; Weiss López, Boris; Santos, Leonardo S.; Araya Maturana, Ramiro (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 ...
    • Intramolecular hydrogen bond in biologically active o-carbonyl hydroquinones 
      Martínez Cifuentes, Maximiliano; Weiss López, Boris; Santos, Leonardo S.; Araya Maturana, Ramiro (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 ...
    • Location, orientation and dynamics of two molecules with mitochondrial activity dissolved in anionic ... 
      Bahamonde-Padilla, Víctor; Martínez Cifuentes, Maximiliano; Muñoz-Masson, Daniel; Ruiz, Álvaro; Ahumada, Hernán; Araya Maturana, Ramiro; Soto Delgado, Jorge; Weiss López, Boris (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 ...
    • Theoretical Study about the Effect of Halogen Substitution on the Reactivity of Antitumor 3-Formylchromones ... 
      Martínez Cifuentes, Maximiliano; Weiss López, Boris; Araya Maturana, Ramiro (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 ...
