Journal ArticleDOI
Bioinspired functional mimics of the manganese catalases
TL;DR: In this article, a review of nonporphyrinic mimics of catalase catalysts is presented, the properties of which are discussed, stressing the role of bridging and terminal ligands on redox potentials and catalysis.
Journal ArticleDOI
Rationally designed mimics of antioxidant manganoenzymes: Role of structural features in the quest for catalysts with catalase and superoxide dismutase activity
TL;DR: In this paper, the role of ligand donor sites, endogenous acid/base groups, metal environment and second-sphere effects in the catalytic activity of synthetic mononuclear Mn complexes with SOD and/or CAT activity is discussed.
Journal ArticleDOI
Oxidation of L-rhamnose and D-mannose by Cr(VI) in perchloric acid. A comparative study
TL;DR: In this paper, the rate law of perchloric acid was shown to hold for L-rhamnose and D-mannose by Cr(VI) in perchlorated acid.
Journal ArticleDOI
Weak interactions modulating the dimensionality in supramolecular architectures in three new nickel(II)-hydrazone complexes, magnetostructural correlation, and catalytic potential for epoxidation of alkenes under phase transfer conditions.

TL;DR: Three different ONO donor acetyl hydrazone Schiff bases have been synthesized from the condensation of acetic hydrazide with three different carbonyl compounds and all complexes are proved to be efficient catalysts for the epoxidation of alkenes by NaOCl under phase transfer condition.
Journal ArticleDOI
Synthesis, characterization and antioxidant activity of water soluble MnIII complexes of sulphonato-substituted Schiff base ligands.
Diego M. Moreno,Verónica Daier,Claudia Palopoli,Jean Pierre Tuchagues,Jean Pierre Tuchagues,Sandra Signorella +5 more
TL;DR: Two new Mn(III) complexes prepared and characterized show dual superoxide dismutase/catalase activity that renders these compounds particularly attractive as catalytic antioxidants.
