Potential antitripanosomal derived from nitro-heterocyclic compounds


Chagas' disease is endemic for most of Latin America, serioulsy affectinq the health of infected people and shortening their lives. Around 16 to 18 million people are estimated to be infected and about 50 thousands of deaths are registered each year in the 21 endemic countries. The therapeutic armamentarium against the parasitosis is scarce, as only two drugs have been used, none of them sufficiently effective at the cronic stage of this disease. Considering that only people from underdeveloped countries are inffected or under the risk of contracting the parasitosis, the interest is relatively low to the countries responsible for the introduction of most part of druqs in the therapeutics. Thus, searching for new drugs against the disease is mainly a task for those underdeveloped countries, from the above, and taking into account the high activity showed by nitro-heterocyclic derivatives that have been already synthesized by our group, and/or others using diverse approaches, our main goal is to find new and effective drug candidates among this class of compounds. This objective will necessarily be supported by in vitro and in vivo assays, besides by mutagenicity tests. The study of mechanism of action of those candidates through electrochemical methodologies, as using biosensors with immobilized nucleic acids and enzymes, and the elucidation of chemical structure-biological activity (QSAR), especially 3D-QSAR, assisted by molecular modeling, are the rational bases for the design of new and more effective nitro-heterocyclic derivatives. We hope to contribute in a integrated way to the search for better antitripanosomal agents. (AU)
