Pt-II, Pd-II and Au-III complexes with a thiosemicarbazone derived from diacethylmonooxime: Structural analysis, trypanocidal activity, cytotoxicity and first insight into the antiparasitic mechanism of action
Ana Cristina Gonçalves,Zumira A. Carneiro,Carolina G. Oliveira,Amanda Danuello,Wendell Guerra,Ronaldo Junio de Oliveira,F. Ferreira,Laudimir L.W. Veloso-Silva,Fernanda Aparecida Heleno Batista,Júlio César Borges,Sérgio de Albuquerque,Victor M. Deflon,Pedro I. S. Maia +12 more
TL;DR: The results showed that complexation of the thiosemicarbazone ligand H2L1 to PtII, PdII and AuIII metal centers enhances the in vitro trypanocidal activity and that the cytotoxicity is dependent on both the metal center and coligands.
Journal ArticleDOI
Heterobimetallic nickel(II) and palladium(II) complexes derived from S-benzyl-N- (ferrocenyl)methylenedithiocarbazate: Trypanocidal activity and interaction with Trypanosoma cruzi Old Yellow Enzyme (TcOYE)
Zumira A. Carneiro,Jackelinne C. Lima,Carla D. Lopes,Ana P S Gaspari,Sérgio de Albuquerque,Luis R. Dinelli,Laudimir L.W. Veloso-Silva,Marcella O. Paganelli,Silvia H. Libardi,Carolina G. Oliveira,Victor M. Deflon,Ronaldo Junio de Oliveira,Júlio César Borges,Pedro I. S. Maia +13 more
TL;DR: Although HFedtc was not processed by the enzyme, it was able to act as a competitive inhibitor, blocking the hydride transfer from the FMN prosthetic group of the enzyme to the menadione substrate, and showed the greater potential between the two complexes studied.
Journal ArticleDOI
Structural studies of Old Yellow Enzyme of Leishmania braziliensis in solution.
Laudimir L.W. Veloso-Silva,Paulo R. Dores-Silva,Dayane Eliara Bertolino-Reis,Louis Fellipe Moreno-Oliveira,Silvia H. Libardi,Júlio César Borges +5 more
TL;DR: The structural studies of the OYE of Leishmania braziliensis are presented, showing that the binding sites in both proteins are essentially similar, and their interactions with the substrate menadione occur with an affinity of the same order of magnitude.
