Chagas' disease is caused by the hemoflagellate protozoan Trypanosoma cruzi, which is predominantly found in South and Central America and Mexico. Although the parasite is present in the United States, confirmed cases of human disease are rare. The most serious manifestation of chronic Chagas' disease is a progressive inflammatory cardiomyopathy. However,(More)
A number of chelating agents and some of their derivatives are as effective as, or superior to, benznidazole, the compound currently in clinical use, in the suppression of the reproduction of epimastigotes of Trypanosoma cruzi, the protozoa that causes Chagas' disease. All compounds were examined at a culture concentration of 5 micrograms/mL. The most(More)
Tetraethylthiuram disulfide (disulfiram) (TETD) and sodium diethylamine-N-carbodithioate (DECD) were examined for their in vitro trypanocidal activity against Trypanosoma cruzi. Benznidazole (BNZ), the drug used clinically for the chemotherapy of Chagas' disease, was used as a positive control. Inhibition assays included evaluation against the epimastigote,(More)
This report describes the syntheses and in vitro trypanocidal activity of a number of iron (III) chelators against epimastigotes of Trypanosoma cruzi. The compounds examined included a number of lipophilic N-alkyl derivatives of 2-ethyl- and 2-methyl-3-hydroxypyrid-4-ones, N,N'-bis(o-hydroxybenzyl)-(+/-)-trans-1,2-diaminocyclohexane,(More)
The relative effectiveness of 20 iron chelating agents in suppressing the growth and multiplication of Trypanosoma cruzi epimastigotes has been examined in vitro. 1,2-Dimethyl-3-hydroxypyrid-4-one (L1) and several of its newly synthesised N-substituted analogs containing hydrophobic substituents were significantly more effective than deferoxamine, even(More)
Agent-based modeling allows researchers to investigate theories of complex social phenomena and subsequently use the model to generate new hypotheses that can then be compared to real-world data. However, computer modeling has been underutilized in regard to the understanding of religious systems, which often require very complex theories with multiple(More)
