The main objective of this project is to prove the biological activity of quinoxaline derivatives in the drug development for tropical diseases such as Chagas' disease and leishmaniasis. More specifically, our goal is the synthesis of quinoxaline derivatives aiming at improving yield, a scalable and safe process and decreasing of chemical residues.Candidates should send CV to Professor Arlene Corrêa: firstname.lastname@example.org.This opportunity is open to candidates of any nationalities.
