    • Chalcone-induced apoptosis through caspase-dependent intrinsic pathways in human hepatocellular carcinoma cells 
      Ramirez-Tagle, Rodrigo; Escobar, Carlos A.; Romero, Valentina; Montorfano, Ignacio; Armisén, Ricardo; Borgna, Vincenzo; Jeldes, Emanuel; Pizarro, Luis; Simon, Felipe; Echeverria, Cesar (MDPI AG, 2016)
      © 2016 by the authors; licensee MDPI, Basel, Switzerland. Hepatocellular carcinoma (HCC) is one of the most commonly diagnosed cancers worldwide. Chemoprevention of HCC can be achieved through the use of natural or synthetic ...
    • Chemical composition of precloacal secretions of two Liolaemus fabiani populations: Are they different? 
      Escobar, Claudio M.; Escobar, Carlos A.; Labra, Antonieta; Niemeyer, Hermann M. (2003)
      The chemical composition of secretions of precloacal pores from two populations of the lizard Liolaemusfabiani (Puilar and Punta-Brava) were compared. This is an endemic species from the Atacama Salt Flat (26°46'S 68° 14'W; ...
    • Evaluation of DIMBOA analogs as antifeedants and antibiotics towards the aphid Sitobion avenae in artificial diets 
      Escobar, Carlos A.; Sicker, Dieter; Niemeyer, Hermann M. (Kluwer Academic/Plenum Publishers, 1999)
      A total of 25 compounds including benzoxazinones, benzoxazolinones, and N-glyoxylamide derivatives were tested as antifeedants and antibiotics towards the aphid Sitobion avenae in diet bioassays. The antifeedant and mortality ...
    • Five bicyclo-[3.3.0]octa-2,6-dienes 
      Vega, Andrés; Donoso-Tauda, Oscar; Ibãez, Andres; Escobar, Carlos A. (2008)
      A series of five compounds containing the bicyclo-[3.3.0]octa-2,6-diene skeleton are described, namely tetra-methyl cis,cis-3,7-dihydroxy-bicyclo-[3.3. 0]octa-2,6-diene-2,4-exo,6,8-exo-tetracarboxyl-ate, C16H18O10, (I), ...
    • Gold nanoparticles for photothermally controlled drug release 
      Guerrero, Ariel R.; Hassan, Natalia; Escobar, Carlos A.; Albericio, Fernando; Kogan Bocian, Marcelo; Araya, Eyleen (Future Medicine Ltd., 2014)
      © 2014 Future Medicine Ltd. In this article, we describe how nanoparticles work in photothermally triggered drug delivery, starting with a description of the plasmon resonance and the photothermal effect, and how this is ...
    • Potential of hydroxamic acids in breeding for aphid resistance in wheat 
      Escobar, Carlos; Niemeyer, Hermann (1993)
      Swedish wheats were analysed at the seedling stage for hydroxamic acids (Hx), a family of natural aphid resistance factors. Analysis comprised the historical development from old landraces to modem cultivars, and included ...
    • Sources of pheromones in the lizard Liolaemus tenuis 
      Labra, Antonieta; Escobar, Carlos A.; Aguilar, Paz M.; Niemeyer, Hermann M. (Sociedad de Biologia de Chile, 2002)
      Experimental tests were conducted with the lizard Liolaemus tenuis (Tropiduridae), to determine the potential sources of pheromones used in its chemical communication, centered in the phenomenon of self-recognition. During ...
    • Structural antitumoral activity relationships of synthetic chalcones 
      Echeverría, César; Santibáñez, Juan Francisco; Donoso Tauda, Óscar; Escobar, Carlos A.; Ramírez Tagle, Rodrigo (2009)
      Relationships between the structural characteristic of synthetic chalcones and their antitumoral activity were studied. Treatment of HepG2 cells for 24 h with synthetic 2'-hydroxychalcones resulted in apoptosis induction ...
    • Synthesis of 1,5-benzodiazepines with unusual substitution pattern from chalcones under solvent-free microwave ... 
      Escobar, Carlos A.; Donoso Tauda, Oscar; Araya Maturana, Ramiro; Sicker, Dieter (2009)
      1,5-Benzodiazepines have been synthesized from the corresponding 2'-hydroxychalcones [1-(2-hydroxyphenyl)-3-aryl-2-propen-1-ones] and o-phenylenediamine, both in methanol, under reflux and under solvent-free microwave ...
