    • 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 of new 4-nitrosophenyl-1,4-dihydropyridines of pharmacological interest 
      Santander Gutiérrez, Ingrid Paola; Núñez Vergara, Luis; Squella Serrano, Juan; Navarrete Encina, Patricio (GEORG THIEME VERLAG KG, 2003-12-18)
      The synthesis and characterization of a series of 4-nitrosophenyl-1.4-dihydropyridines derived from the respective nitro compounds of pharmacological interest is described. The complete synthetic pathway is based on the ...
    • Synthesis of new 4-nitrosophenyl-1,4-dihydropyridines of pharmacological interest 
      Santander Gutierrez, Ingrid Paola; Núñez Vergara, Luis; Squella Serrano, Juan; Navarrete Encina, Patricio (GEORG THIEME VERLAG KG, 2003-12-18)
      The synthesis and characterization of a series of 4-nitrosophenyl-1.4-dihydropyridines derived from the respective nitro compounds of pharmacological interest is described. The complete synthetic pathway is based on the ...
    • Synthesis of some C-3,4,5-substituted 2,6-dimethyl-1,4-dihydropyridines (4-DHPs) 
      Navarrete Encina, Patricio; Squella Serrano, Juan; Carbajo, J.; Conde, B.; Núñez Vergara, Luis (TAYLOR & FRANCIS INC, 2007)
      A series of C-3,4,5-substituted 2,6-dimethyl-1,4-dihydropyridines ( 1,4-DHPs) with pharmacological properties were prepared by a variation from the classical Hantzsch synthesis. The procedure involves treatment of the ...
    • Unexpected diastereotopic behaviour in the H-1 NMR spectrum of 1,4-dihydropyridine derivatives triggered ... 
      Da Silva, Jaqueline; Barría, Claudio; Jullian Matthaei, Carolina; Navarrete Encina, Patricio; Núñez Vergara, Luis; Squella Serrano, Juan (SOC BRASILEIRA QUIMICA, 2005-01)
      1,4-dihydropyridine derivatives constitute an important pharmacological group for the treatment of cardiovascular diseases. We have synthesised a series 4-(5'-nitro-2'-furyl)-1,4-dihydropyridine derivatives, which were ...
    • Voltammetric studies of aromatic nitro compounds: pH-dependence on decay of the nitro radical anion in mixed media 
      Carbajo, J.; Bollo Dragnic, Soledad; Núñez Vergara, Luis; Navarrete Encina, Patricio; Squella Serrano, Juan (ELSEVIER SCIENCE, 2000-12-01)
      In this report we have chosen ethyl-m-nitrobenzoate (EMNB) as a prototype of a nitroaromatic compound in order to carry out a detailed cyclic voltammetric study focused on the coupled chemical reaction of the generated ...
    • X-ray study of bilayered tilted structures in liquid crystalline side chain methacrylic polymers 
      Soto Bustamante, Eduardo; Vergara Toloza, Rafael Orlando; Saldaño Hurtado, Danilo; Navarrete Encina, Patricio (TAYLOR & FRANCIS LTD, 2003-05)
      The synthesis and measurement of thermodynamic properties of six methacrylate-based polymers were undertaken to observe the relationship between structural aliphatic features and mesophase properties. X-ray measurements ...
