Interaction of [(VO)-O-IV(acac)(2)] with Human Serum Transferrin and Albumin
Correia, Isabel; Chorna, Ielyzaveta; Cavaco, Isabel; Roy, Somnath; Kuznetsov, Maxim L.; Ribeiro, Nadia; Justino, Goncalo; Marques, FernandaVO(acac)(2)] is a remarkable vanadium compound and has potential as a therapeutic drug. It is important to clarify how it is transported in blood, but the reports addressing its binding to serum proteins have been contradictory. We use several spectroscopic and mass spectrometric techniques (ESI and MALDI-TOF), small-angle X-ray scattering and size exclusion chromatography (SEC) to characterize solutions contai...
Evaluation of the binding of four anti-tumor Casiopeinas to human serum albumin
Correia, Isabel; Borovic, Sladjana; Cavaco, Isabel; Matos, Cristina P.; Roy, Somnath; Santos, Hugo M.; Fernandes, Luz; Capelo, Jose L.The metal complexes designated by Casiopeinas (R) are mixed-ligand Cu-II-compounds some of them having promising antineoplastic properties. We report studies of binding of Cu(glycinato)(4,7-dimethyl-1,10-phenanthroline) (Cas-II-Gly (1)), Cu(acetylacetonato)(4,7-dimethy1-1,10-phenanthroline) (Cas-III-Ea (2)), Cu(glycinato) (4,4'-dimethyl-2,2'-bipyridine) (Cas-W-Gly (3)) and Cu(acetylacetonato)(4,4'-dimethyl-2,2'...
