    • Electrochemical, ESR, theoretical studies and in vitro anti-t. cruzi activity of 2-Organometallic-5-Nitro ... 
      Barriga González, Germán; Olivares Petit, Carla; Toro, Patricia M.; Klahn, A. Hugo; Olea Azar, Claudio; Maya Arango, Juan D.; Huentupil, Yosselin; Arancibia, Rodrigo (Soc. Chilena de Química, 2020)
      The bioorganometallic compounds 2-cyrhetrenyl-5-nitro-benzimidazole (Bzn-1) and 2-ferrocenyl-5-nitro-benzimidazole (Bzn-2) have been proposed as potential anti-Trypanosoma cruzi agents. In this regard, electrochemical, ...
    • Evaluation of the Antioxidant Activity of the Flavonoids Isolated from Heliotropium Sinuatum Resin Using ... 
      Barriga González, Germán; Chamorro, Eduardo; Salinas, Melissa; Modak, Brenda; Olea Azar, Claudio (Sociedad Chilena Química, 2016)
      The antioxidant capacity has been determined for a number of flavonoid compounds from Heliotropium sinuatum, a plant that grows in arid areas in the north of Chile. The methodologies used were: ORAC(FL) (oxygen radical ...
    • Nitrones: a potential new alternative as therapeutic agents 
      Barriga González, Germán Eduardo; Aliaga, Carolina; Olea Azar, Claudio; Zúniga López, María C.; González, Mercedes; Cerecetto, Hugo (Bentham Science Publishers Ltd., 2017)
      Background: Nowadays, nitrones are the most used spin traps to characterize free radicals in biological systems due to the versatility and variety depending on the types of radicals to study and that the half-lives of the ...
    • Synthesis and antioxidant study of new polyphenolic hybrid-coumarins 
      Pérez Cruz, Karina Angélica; Moncada-Basualto, Mauricio; Morales Valenzuela, Javier; Barriga González, Germán; Navarrete Encina, Patricio; Núñez Vergara, Luis; Squella Serrano, Juan; Olea Azar, Claudio (Elsevier, 2018-05)
      The antioxidant capacity of hydroxylated coumarins and hydroxybenzoic acids has been widely described. However, there is little information on the antioxidant activity when both systems are functionalized. In this work, ...
    • 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 ...
