    • 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 ...
    • Electrospray ionization mass spectrometric fragmentation of hydroquinone derivatives 

      Almodovar, Iriux; Ramírez Rodríguez, Oney; Barriga, Andrés; Caroli Rezende, Marcos; Araya Maturana, Ramiro (Wiley, 2011)
      The fragmentation patterns of nine di-, tri- and tetracyclic hydroquinones with potential antitumor activity were rationalized by invoking competing mechanisms that included sterically accelerated homolytic cleavage, ...
    • Electrospray ionization mass spectrometric fragmentation of hydroquinone derivatives - ERRATUM 

      Almodovar, Iriux; Ramírez Rodríguez, Oney; Barriga, Andrés; Caroli Rezende, Marcos; Araya Maturana, Ramiro (Wiley, 2011)
    • Experimental and theoretical reduction potentials of some biologically active ortho-carbonyl para-quinones 

      Martínez Cifuentes, Maximiliano; Salazar, Ricardo; Ramírez Rodríguez, Oney; Weiss López, Boris; Araya Maturana, Ramiro (MDPI AG, 2017)
      The rational design of quinones with specific redox properties is an issue of great interest because of their applications in pharmaceutical and material sciences. In this work, the electrochemical behavior of a series of ...
    • NMR assignment in regioisomeric hydroquinones 

      Dobado, Jose A.; Gómez-Tamayo, José C.; Calvo-Flores, Francisco G.; Martínez-García, Henar; Cardona, Wilson; Weiss López, Boris; Ramírez Rodríguez, Oney; Pessoa Mahana, Hernán; Araya Maturana, Ramiro (2011)
      A set of regioisomeric pairs of tricyclic hydroquinones, analogues of antitumor 9,10-dihydroxy-4,4-dimethyl-5,8-dihydroanthracen-1(4H)-one (1) and other derivatives, were synthesized and their regiochemistry and NMR spectra ...
    • Small structural changes on a hydroquinone scaffold determine the complex I inhibition or uncoupling of tumoral oxidative phosphorylation 

      Urra Faúndez, Félix; Córdova Delgado, Miguel; Lapier, Michel; Orellana Manzano, Andrea; Acevedo Arévalo, Luis; Pessoa Mahana, Hernán; González Vivanco, Jaime; Martínez Cifuentes, Maximiliano; Ramírez Rodríguez, Oney; Millas Vargas, Juan; Weiss López, Boris; Pavani, Mario; Ferreira Parker, Jorge; Araya Maturana, Ramiro (Academic Press Elsevier Science, 2016)
      Mitochondria participate in several distinctiveness of cancer cell, being a promising target for the design of anti-cancer compounds. Previously, we described that ortho-carbonyl hydroquinone scaffold 14 inhibits the complex ...
