REPU MAGAZINE N 3 2016 REPU Research Projects 2017 REPU - Chemistry Diego Nieto - University of Navarra Organic and Pharmaceutical Chemistry Department, Spain Malaria is a life-threatening disease that is typically transmitted through the bite of an Anopheles mosquito infected with a Plasmodium species organism. This tropical disease continues affecting large parts of the world and there are no long-term sustainable treatments available yet. Currently, artemisinin-based combination therapies are the mainstay of antimalarial treatment but in recent years parasite resistance against artemisinin and its derivatives has emerged and spread. In order to handle this challenge, new antimalarial entities are needed. Potent antimalarial drugs, such as quinine, mefloquine, lumefantrine and halofantrine owe their high antiplasmodial activity and ADMET values to the presence of an arylamino alcohol moiety into the structure. Based on this antiplasmodial pharmacophore, Diego Nieto worked in the Laboratory of Synthesis of the Department of Organic and Pharmaceutical Chemistry of the University of Navarra, mainly in the development of new molecules that could meet the structure, activity and ADMET requirements of an active antimalarial drug, a crucial step in the drug discovery process. nanoREPU Ricardo Vilchez - McMaster University Turak Laboratory, Canada In the past years, the price of fossil fuel has increased more than anytime in recent memory. Hence, the race for an alternate energy source to replace or lessen the use of fossil fuels has risen. The activity of creating electricity using organic solar cells is an example of a sustainable energy source. This technology also uses nanoparticles that exhibit unique properties, like Nanostructured titanium dioxide (TiO2), which attracts significant attention in the field of photocatalysis, photonic crystals, optical emission and sensing, because of its optical and catalytic properties. During his internship at the Organic Electronic Interface Laboratory at McMaster University, Ricardo focused on a solution of the charge transport problem on organic solar cells through the synthesis of titanium dioxide nanoparticles by reverse micelle technique and characterizing them with an atomic force microscope (AFM). Also, he studied the array order of the micelles and how can change it. 13
