摘要

Triosephosphate isomerase from Trypanosoma cruzi (TcTIM), an enzyme in the glycolytic pathway that exhibits high catalytic rates of glyceraldehyde-3-phosphate- and dihydroxyacetone-phosphate-isomerization only in its dimeric form, was screened against an in-house chemical library containing nearly 230 compounds belonging to different chemotypes. After secondary screening, twenty-six compounds from eight different chemotypes were identified as screening positives. Four compounds displayed selectivity for TcTIM over TIM from Homo sapiens and, concomitantly, in vitro activity against T. cruzi.
