Resumen
In this work we reported the synthesis and the trypanocidal profile of new 1,3,4-thiadiazole-2-arylhydrazone derivatives of nitroimidazole series (4) or phenyl series (5), designed by exploring the molecular hybridization approach between megazol (2) and guanyl hydrazone derivative (3). The evaluation of the activity against bloodstream trypomastigote forms of Trypanosoma cruzi forms lead us to identify a new potent trypamomicide prototype, that is, brazilizone A (4k), which present an IC50/24 h=5.3 microM. 2022-01-01
