Attainment of Pentagonal-Bipyramidal LnIII Complexes from a Planar Pentadentate Ligand
(MDPI, 2020)The search for mononuclear lanthanoid-based single-ion magnets (SIMs) has increased the interest in some coordination environments with low coordination numbers, in combination with an axial symmetry, as they could maximize ... -
Biomimetic Catalysts for Oxidation of Veratryl Alcohol, a Lignin Model Compound
(MDPI, 2013)Kraft pulp has to be bleached to eliminate the chromophoric structures, which cause a darkening of the pulp. In Nature, an equivalent role is assumed by ligninolytic enzymes such as lignin peroxidases, manganese peroxidases ... -
Canonical DNA minor groove insertion of bisbenzamidine–Ru(ii) complexes with chiral selectivity
(Royal Society of Chemistry, 2019)We report the first Ru(II) coordination compounds that interact with DNA through a canonical minor groove insertion mode and with selectivity for A/T rich sites. This was made possible by integrating a bis-benzamidine minor ... -
A chemosensor for dihydrogenphosphate based on an oxoazamacrocycle possessing three thiourea arms
(Royal Society of Chemistry, 2012)We report a new H-bond macrocyclic chromogenic chemosensor in organic media, H3L, which displayed drastic changes in its UV–vis spectra revealing selectivity for dihydrogenphosphate over other inorganic anions, such as ... -
Combined Effect of Caspase-Dependent and Caspase-Independent Apoptosis in the Anticancer Activity of Gold Complexes with Phosphine and Benzimidazole Derivatives
(MDPI, 2021)Since the potential anticancer activity of auranofin was discovered, gold compounds have attracted interest with a view to developing anticancer agents that follow cytotoxic mechanisms other than cisplatin. Two benzimidazole ... -
Computational and Experimental Studies Into the Conformations of a Triptycene-Based Ditopic Ligand
(MDPI, 2015)We present a combined computational and experimental study of the possible conformations adopted by a ditopic Schiff base ligand based on triptycene. We have performed DFT calculations on a Y-shaped Schiff base ligand ... -
Copper(II) Complexes of Cyclams Containing Nitrophenyl Substituents: Push–Pull Behavior and Scorpionate Coordination of the Nitro Group
