      Arriagada, Francisco; Ugarte Núñez, Catalina; Günther Sapunar, Germán; Larraín Barth, María Angélica; Guarnizo Herrero, Víctor; Nonell, Santi; Morales Valenzuela, Javier (MDPI, 2020)
      The incorporation of pigments and natural polyphenols into inorganic matrices, resulting in a hybrid material that improves the resistance and chemical stability of the pigments and the antioxidant capacity of the materials, ...
    • Estudio comparativo de la liberación in vitro de la asociación de lidocaína-prilocaína desde preparados magistrales 

      Ferrufino Zarges, Felipe Andrés (Universidad de ChileCyberDocs, 2011)
      La administración de fármacos a través de la piel es una práctica muy utilizada en dermatología. La vía de administración cutánea es poco invasiva, de fácil acceso y en cierta manera, es segura debido a la externalidad de ...
    • Nanoantioxidant–Based silica particles as flavonoid carrier for drug delivery applications 

      Arriagada, Francisco; Gunther Sapunar, Germán; Morales Valenzuela, Javier (MDPI, 2020)
      Nanosystems used in pharmaceutical formulations have shown promising results in enhancing the administration of drugs of difficult formulations. In particular, porous silica nanoparticles have demonstrated excellent ...
    • Organic and Inorganic Nanoparticles for Prevention and Diagnosis of Gastric Cancer 

      Oyarzún Ampuero, Felipe; Guerrero Hernández, Ariel; Hassan López, Natalia; Morales Valenzuela, Javier; Bollo Dragnic, Soledad; Corvalán Rodríguez, Alejandro; Quest, Andrew F. G.; Kogan Bocian, Marcelo (Bentham, 2015)
      Organic and inorganic nanoparticles show great potential for cancer diagnosis and treatment. Because gastric cancer (GC) represents the second most deadly type of neoplasia worldwide, continued research efforts by scientists ...
    • Substituent Effect on the Photolability of 4-Aryl-1,4-Dihydropyridines 

      García, Cristóbal; Cabezas, Karina; Nonell, Santi; Núñez Vergara, Luis; Morales Valenzuela, Javier; Günther Sapunar, Germán; Pizarro Urzúa, Nancy Alejandra (The American Society of Photobiology, 2014)
      The electronic nature of substituents attached to the 4-aryl moiety of 1,4-dihydropyridines strongly affects the photophysical and photochemical behavior of these family of compounds. The presence of an electron donor ...
    • 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, ...
