Journal ArticleDOI
The wide pharmacological versatility of semicarbazones, thiosemicarba-zones and their metal complexes.
Heloisa Beraldo,Dinorah Gambino +1 more
TL;DR: The more significant bioactivities of a variety of semicarbazones (anti-protozoa, anticonvulsant) and thiosemicarbazone and their metal complexes are reviewed together with proposed mechanisms of action and structure-activity relationships.
Journal ArticleDOI
Palladium(II) complexes of 2-benzoylpyridine-derived thiosemicarbazones: spectral characterization, structural studies and cytotoxic activity.
Anayive P. Rebolledo,Marisol Vieites,Dinorah Gambino,Oscar E. Piro,Eduardo E. Castellano,Carlos L. Zani,Elaine Maria de Souza-Fagundes,Letícia R. Teixeira,Alzir A. Batista,Heloisa Beraldo +9 more
TL;DR: All complexes show a quite similar planar fourfold environment around palladium(II).
Journal ArticleDOI
Iron(III)-adriamycin and Iron(III)-daunorubicin complexes: physicochemical characteristics, interaction with DNA, and antitumor activity.
TL;DR: Using potentiometric and spectroscopic measurements, it is shown that adriamycin and daunorubicin form two well-defined species with Fe(III), which can be formulated as respectively Fe(HAd)3 and Fe( HDr)3.
Journal ArticleDOI
Copper(II) and zinc(II) complexes with 2-benzoylpyridine-methyl hydrazone
Angel A. Recio Despaigne,Jeferson G. Da Silva,Ana Cerúlia M. do Carmo,Oscar E. Piro,Eduardo E. Castellano,Heloisa Beraldo +5 more
TL;DR: In this paper, the crystal structures of 2-Benzoylpyridine-methyl hydrazone (HBzMe) have been determined and its copper(II) [Cu(Bzme)Cl2] (1) and zinc(II] [Zn(HBzME)Cl 2] (2) complexes have been obtained.
Journal ArticleDOI
Tin(IV) complexes of 2‐benzoylpyridine N(4)‐phenyl‐thiosemicarbazone: spectral characterization, structural studies and antifungal activity

TL;DR: In this paper, three tin-IV complexes of 2-benzoylpyridine N(4)-phenylthiosemicarbazone (H2Bz4Ph) were prepared: [Sn(L)Cl3] (1), [BuSnCl2] (2) and [(Bu)2SnCl] (3), where L stands for the anionic ligand formed upon complexation with deprotonation and release of HCl.
