Proteases and peptidases inTrypanosoma cruzi are considered potential targets for antichagasic chemotherapy. We monitored changes in low-mass metabolites inT. cruzi epimastigotes treated with bestatin, a dipeptide metalloaminopeptidase inhibitor. After treatment, multiple dipeptides were shown to be increased, confirmingin situ inhibition of the leucine aminopeptidase ofT. cruzi (LAPTc) and probably other peptidases.
