    Abstract:
    Chagas' disease (CD) has been responsible for many deaths and disabilities mainly in South America. Currently, 40 million people are at risk of acquiring this disease and, existing therapies are still unsatisfactory, presenting harsh side effects. Therefore, the development of new chemical entities to reverse this state is critical. A series of peptidomimetics, developed by Mc Kie et al. (2001) [11], showed a reversible and competitive inhibition against Trypanosoma cruzi Trypanothione Reductase (TR). These inhibitors may be used as basis of lead compounds in the design of new drug candidates for the treatment of CD. In this work, we have docked this series of peptidomimetics into the TR binding site, using the FlexX algorithm as implemented in the Sybyl program, in order to access the binding mode of this class of compounds in the target enzyme.
