Characterized cis-FeV(O)(OH) intermediate mimics enzymatic oxidations in the gas phase
Autor: Margarida Borrell, Erik Andris, Rafael Navrátil, Jana Roithová, Miquel Costas
Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-9 (2019)
FeV(O)(OH) species have long been thought to play a role in a range of enzymatic oxidations, but their characterization has remained elusive. Here, using gas-phase ion spectroscopy, the authors characterize an FeV(O)(OH) species and find that its rea

Effective Tetradentate Compound Complexes against Leishmania spp. that Act on Critical Enzymatic Pathways of These Parasites
Autor: Kristína Urbanová, Inmaculada Ramírez-Macías, Rubén Martín-Escolano, María José Rosales, Olaf Cussó, Joan Serrano, Anna Company, Manuel Sánchez-Moreno, Miquel Costas, Xavi Ribas, Clotilde Marín
Publikováno v: Molecules, Vol 24, Iss 1, p 134 (2018)
The spectrum and efficacy of available antileishmanial drugs is limited. In the present work we evaluated in vitro the antiproliferative activity of 11 compounds based on tetradentate polyamines compounds against three Leishmania species (L. brazilie

Pro-Oxidant Activity of Amine-Pyridine-Based Iron Complexes Efficiently Kills Cancer and Cancer Stem-Like Cells.
Autor: Marta González-Bártulos, Clara Aceves-Luquero, Jamal Qualai, Olaf Cussó, M Angeles Martínez, Silvia Fernández de Mattos, Javier A Menéndez, Priam Villalonga, Miquel Costas, Xavi Ribas, Anna Massaguer
Publikováno v: PLoS ONE, Vol 10, Iss 9, p e0137800 (2015)
Differential redox homeostasis in normal and malignant cells suggests that pro-oxidant-induced upregulation of cellular reactive oxygen species (ROS) should selectively target cancer cells without compromising the viability of untransformed cells. Co

Reversible Deactivation of Manganese Catalysts in Alkene Oxidation and H2O2 Disproportionation
Autor: Johann B. Kasper, Laia Vicens, C. Maurits de Roo, Ronald Hage, Miquel Costas, Wesley R. Browne
Publikováno v: ACS Catalysis, 13(9), 6403-6415. AMER CHEMICAL SOC
Mononuclear MnII oxidation catalysts with aminopyridine-based ligands achieve high turnover-number (TON) enantioselective epoxidation of alkenes with H2O2. Structure reactivity relations indicate a dependence of enantioselectivity and maximum TON on

A Common Active Intermediate in the Oxidation of Alkenes, Alcohols and Alkanes with H2O2 and a Mn(II)/Pyridin-2-Carboxylato Catalyst
Autor: Johann B. Kasper, Pattama Saisaha, Maurits de Roo, Mitchell J. Groen, Laia Vicens, Margarida Borrell, Johannes W. de Boer, Ronald Hage, Miquel Costas, Wesley R. Browne
Publikováno v: ChemCatChem, 15(1):e202201072. WILEY-V C H VERLAG GMBH
The mechanism and the reactive species involved in the oxidation of alkenes, and alcohols with H2O2, catalysed by an in situ prepared mixture of a MnII salt, pyridine-2-carboxylic acid and a ketone is elucidated using substrate competition experiment

Site-selective methylene C–H oxidation of an alkyl diamine enabled by supramolecular recognition using a bioinspired manganese catalyst
Autor: Arnau Vicens, Laia Vicens, Giorgio Olivo, Osvaldo Lanzalunga, Stefano Di Stefano, Miquel Costas
Publikováno v: Faraday Discussions.
A manganese catalyst equipped with 18-benzo-6-crown ether receptors has been employed in the catalytic oxidation of tetradecane-1,14-diamine. Binding of the protonated amines results in selective (up to 92%) oxidation of the C6/C7 methylenic sites.

Consequences in Hydrogen Atom Transfer Reactivity Angewandte Chemie 62 2 e202211361
Two oxoiron(IV) isomers (R2a and R2b) of general formula [FeIV(O)(RPyNMe3)(CH3CN)]2+ are obtained by reaction of their iron(II) precursor with NBu4IO4. The two isomers differ in the position of the oxo ligand, cis and trans to the pyridine donor. The
