Abstract
Chagas Disease, also known as American trypanosomiasis, is a Neglected Tropical Disease that affects around seven million people, especially in Latin America. Noteworthy, there has been an increase in the numbers of case reports in non-endemic areas, such as North America, Europe, Japan, and Australia. The disease is a vector-borne disease caused by the pathogen Trypanosoma cruzi being transmitted by infected bugs. It is known that about forty percent of infected patients develop cardiac, digestive, or neurological alterations. There are only two drugs currently used for treatment, benznidazole and nifurtimox. However, both therapeutic regimens present several limitations, such as toxicity, mutagenicity and low efficiency during the chronic phase. Some reports in the literature point to the occurrence of parasite resistance. To overcome these limitations, the bioprospection of novel molecules as alternatives is one of the major goals to improve therapeutic success in this chronic disease. Bioprospecting active metabolites from natural resources might bring new hopes for disease control and parasite elimination. Here we summarize the most recent advances to identify and test Algae, Bacteria and Fungi-derived bioactive compounds with trypanocidal activity using experimental models, in vitro testing and in silico approaches.
Keywords: Chagas disease, trypanosoma cruzi, virulence factors, therapeutics, algal proteins, fungal proteins.
