Investigation of Novel Isatinylhydantoin Derivatives as Potential Anti‐Kinetoplastid Agents

open access: yesChemMedChem, Volume 20, Issue 1, January 2, 2025.
A series of isatinylhydantoin derivatives were synthesized and investigated for antileishmanial and antitrypanosomal activities in vitro and in vivo. The derivative 5 was identified with higher leishmanicidal activity than the clinical drug amphotericin B while 4b was uncovered as in vitro trypanocidal hit against T. congolense parasite.
