2020-01-08T10:10:24Z urn:hdl:10259/5200 Synthesis, characterization, DFT calculations and anticancer activity of a new oxidovanadium(iv) complex with a ligand derived from o-vanillin and thiophene Rodríguez, María R. Balsa, Lucía M. Plá, Julián del García Tojal, Javier Pis Diez, Reinaldo Parajón Costa, Beatriz S. León, Ignacio E. González Baró, Ana C. From the interaction of the vanadyl ion with a ligand (HL), obtained by the condensation reaction of o-vanillin and 2-thiophenemethylamine, an oxidovanadium(IV) complex (VOL2) was obtained. It was characterized by spectroscopic techniques, including solid state FTIR, Raman, EPR and diffuse reflectance, and UV-vis and EPR, in solution. Its thermal behavior was analyzed by means of TGA and DTA. Theoretical studies based on DFT computational methods aided in the interpretation and assignment of spectroscopic data. Cytotoxicity assays (48 h) against bone cancer cells (MG-63, IC50 = 50.4 ± 8.7), breast cancer cells (MCF-7, IC50 = 42.3 ± 4.7), (MDA-MB-231, IC50 = 29.0 ± 1.7) and a normal fibroblast (L929, IC50 = 71.0 ± 3.5) demonstrated the enhancement of the effectiveness and selectivity of the complex as compared with both the ligand and the free metal ion. Besides, the compound inhibits cell migration, increases ROS levels and facilitates apoptosis. On a whole, these results show the main mechanisms of the deleterious effects of [VOL2] in a triple negative breast cancer cell line (MDA-MB-231), demonstrating that this complex is a promising therapeutic agent for this kind of breast cancer. 2020-01-08T10:10:24Z 2020-01-08T10:10:24Z 2019 info:eu-repo/semantics/article 1144-0546 http://hdl.handle.net/10259/5200 10.1039/C9NJ02092F 1369-9261 eng New Journal of Chemistry. 2019, V. 43, n. 29, p. 11784-11794 https://doi.org/10.1039/C9NJ02092F info:eu-repo/grantAgreement/JCyL/BU076U16 info:eu-repo/grantAgreement/JCyL/BU022G18 info:eu-repo/grantAgreement/MINECO/CTQ2016-75023-C2-1-P info:eu-repo/grantAgreement/MINECO/CTQ2015-70371- REDT info:eu-repo/grantAgreement/CONICET-CCT-La Plata/PIP-0651 info:eu-repo/grantAgreement/CONICET-CCT-La Plata/PIP-0034 info:eu-repo/grantAgreement/ANPCyT/PICT 2016-1574 info:eu-repo/grantAgreement/UNLP/11-X763 info:eu-repo/semantics/openAccess Royal Society of Chemistry
