Vanadium(V) complexes with salicylaldehyde semicarbazone derivatives bearing in vitro anti-tumor activity toward kidney tumor cells (TK-10): crystal structure of [VVO2(5-bromosalicylaldehyde semicarbazone)].
Pabla Noblía,Marisol Vieites,Beatriz S. Parajón-Costa,E. J. Baran,Hugo Cerecetto,Patricia Draper,Mercedes González,Oscar E. Piro,Eduardo E. Castellano,Amaia Azqueta,Adela López de Cerain,Antonio Monge-Vega,Dinorah Gambino +12 more
TL;DR: Results showed that structural modifications on the semicarbazone moiety could have a significant effect on the anti-tumor activity of the vanadium complexes, and no apparent correlation could be demonstrated between reduction potentials of the complexes and their anti-Tumor activities.
Journal ArticleDOI
Selective interaction of lower rim calix[4]arene derivatives and bivalent cations in solution. Crystallographic evidence of the versatile behavior of acetonitrile in lead(II) and cadmium(II) complexes.
TL;DR: The interaction of lower rim calix(4)arene derivatives containing ester (1) and ketone (2) functional groups and bivalent (alkaline-earth, transition- and heavy-metal) cations has been investigated in various solvents and the selective behavior of 1 and 2 for bivalent cations is demonstrated for the first time.
Journal ArticleDOI
Photochemical and photophysical reactions of fac-rhenium(I) tricarbonyl complexes. Effects from binucleating spectator ligands on excited and ground state processes
TL;DR: The ground and excited state properties of the newly prepared complexes Re(CO)3(2,2'biquinoline)LS+, LS = pyrazine or 4,4'bipyridine, and Re( CO)3 (2, 2 'bipy)(2-pyrazinecarboxylate) were investigated by steady state and time-resolved spectroscopy as mentioned in this paper.
Journal ArticleDOI
New Vanadium(V) Complexes with Salicylaldehyde Semicarbazone Derivatives: Synthesis, Characterization, and in vitro Insulin-Mimetic Activity − Crystal Structure of [VvO2(salicylaldehyde semicarbazone)]
Pabla Noblía,Enrique J. Baran,Lucía Otero,Patricia Draper,Hugo Cerecetto,Mercedes González,Oscar E. Piro,Eduardo E. Castellano,Toshifumi Inohara,Yusuke Adachi,Hiromu Sakurai,Dinorah Gambino +11 more
TL;DR: In this article, the new dioxo(semicarbazone)vanadium(V) complexes cis-VO2L have been synthesized, characterized by 1H and 13C NMR and FTIR spectroscopy and tested for bioactivity as potential insulin mimetic agents.
Journal ArticleDOI
Synthesis and characterization of new ruthenium complexes with active ligands against Chagas' disease
Lucía Otero,Pabla Noblía,Dinorah Gambino,Hugo Cerecetto,Mercedes González,Javier Ellena,Oscar E. Piro +6 more
TL;DR: In this article, the synthesis and characterization of a series of new Ru(II) complexes with different antitrypanosomal active compounds is presented, where ruthenium clotrimazole complexes are more active against Trypanosoma cruzi, causative agent of Chagas' disease, than the corresponding free ligand.
