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.

Heterocyclic systems containing S/N regioselective nucleophilic competition: facile synthesis, antitubercular and antimicrobial activity of thiohydantoins and iminothiazolidinones containing the benzo[b]thiophene moiety [PDF]

open access: yesJournal of the Serbian Chemical Society, 2005
The required compounds N-aryl-N'-(3-chloro-2-benzo[b]thenoyl)–thioureas 1a–k were prepared by condensing 3-chloro-2-benzo[b]thenoyl chloride with different arylamines using ammonium thiocyanate, which in turn when treated with chloroacetic acid, yielded ...

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

open access: yesEuropean 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.

Chiral Quaternary Ammonium Salt‐Catalyzed Enantioselective Addition Reactions of Hydantoins

open access: yesHelvetica Chimica Acta, Volume 107, Issue 3, March 2024.
Abstract We herein report a protocol for the asymmetric 1,4‐addition of hydantoins to various Michael acceptors by utilizing Cinchona alkaloid‐based chiral quaternary ammonium salt catalysts. Various products were obtained with moderate to good enantioselectivities and accompanying computational investigations helped to identify key interactions ...

Crystal Structure of Crataeva tapia Bark Protein (CrataBL) and Its Effect in Human Prostate Cancer Cell Lines

open access: yes, 2013
A protein isolated from the bark of Crataeva tapia (CrataBL) is both a Kunitz-type plant protease inhibitor and a lectin. We have determined the amino acid sequence and three-dimensional structure of CrataBL, as well as characterized its selected ...

Dopaminergic neuronal death via necroptosis in Parkinson's disease: A review of the literature

open access: yesEuropean Journal of Neuroscience, Volume 59, Issue 6, Page 1079-1098, March 2024.
We reviewed the current literature on the potential role of necroptosis, a recently characterized regulated cell death mechanism, in Parkinson's disease (PD) pathogenesis. We summarized findings from studies on necroptosis in PD preclinical models and PD human tissue samples, discussing how manipulating necroptosis might open a novel therapeutic ...
