Investigation of Novel Isatinylhydantoin Derivatives as Potential Anti‐Kinetoplastid Agents

ChemMedChem, 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.

1,2‐Diaza‐1,3‐Dienes as a Multifaceted Synthons for the Synthesis of Heterocycles: A Fifteen‐Years Update

European Journal of Organic Chemistry, Volume 27, Issue 44, November 25, 2024.
1,2‐Diaza‐1,3‐butadienes, also called azoalkenes, have received considerable attention as key synthons for constructing various heterocyclic scaffolds. This minireview summarizes the contribution of our group in this field over the period from 2009 to the present, focusing on the role of the azoene building block in forming the heterocyclic structures.
