    • Synthesis and electrochemical and biological studies of novel coumarin-chalcone hybrid compounds 
      Pérez Cruz, Fernanda; Vazquez Rodriguez, Saleta; Matos, Maria João; Herrera Morales, Alejandra; Villamena, Frederick A.; Das, Amlan; Gopalakrishnan, Bhavani; Olea Azar, Claudio; Santana, Lourdes; Uriarte, Eugenio (2013)
      A series of novel hydroxy-coumarin-chalcone hybrid compounds 2a-i has been synthesized by employing a simple and efficient methodology. An electrochemical characterization using cyclic voltammetry and ESR spectroscopy were ...
    • Synthesis and electrochemical oxidation of hybrid compounds: Dihydropyridine-fused coumarins 
      Pardo Jiménez, Viviana Gladys; Barrientos, C.; Pérez Cruz, Karina Angélica; Navarrete Encina, Patricio; Olea Azar, Claudio; Núñez Vergara, Luis; Squella Serrano, Juan (2014)
      In this paper, a series of six dihydropyridine-fused coumarins were synthesized and electrochemically characterized in dimethylformamide (DMF). Dihydropyridine ring oxidation on glassy carbon electrode (GCE) for condensed ...

    • Synthesis and evaluation of new heteroaryl nitrones with spin trap properties 
      Barriga González, G.; Aliaga, C.; Chamorro, E.; Olea Azar, Claudio; Norambuena, E.; Porcal, W.; González, M.; Cerecetto, H. (Royal Society of Chemistry, 2020)
      A new series of heteroaryl nitrones were synthesized and evaluated as free radical traps due to the results showed in our previous report. The physicochemical characterization of these new nitrones by electron spin resonance ...
    • Synthesis of silver nanoparticles using aqueous leaf extract of mimosa albida (Mimosoideae): characterization ... 
      Pilaquinga, Fernanda; Amaguana, Dennis; Morey, Jeroni; Moncada-Basualto, Mauricio; Pozo Martínez, Josué; Olea Azar, Claudio; Fernández, Lenys; Espinoza Montero, Patricio; Jara Negrete, Elisa; Meneses, Lorena; López, Fernanda; Debut, Alexis; Piña, Nieves (MDPI, 2020)
      The search for sensitive and rapid analytical techniques for the determination of natural antioxidants is an area in constant growth due, among other aspects, to the complexity of plant matrices. In this study, silver ...
