A Simple and Robust Model for Predicting the Reduction Potential of Quinones Family; Electrophilicity Index Effect

International Journal of Electrochemical Science, 2012
This paper describes a procedure revealing the relationship between quantum chemical indices and electronic descriptors as independent variables and half-wave potential (E1/2) of quinones family as a dependent variable.

It Takes Two to Tango, Part II: Synthesis of A-Ring Functionalised Quinones Containing Two Redox-Active Centres with Antitumour Activities

Molecules, 2023
In 2021, our research group published the prominent anticancer activity achieved through the successful combination of two redox centres (ortho-quinone/para-quinone or quinone/selenium-containing triazole) through a copper-catalyzed azide-alkyne ...

Polyphenol-Protein Complexes and Their Consequences for the Redox Activity, Structure and Function of Honey. A Current View and New Hypothesis – a Review

Polish Journal of Food and Nutrition Sciences, 2015
There is increasing evidence that protein complexation by honey polyphenols is changing honey structure and function. This relatively less investigated filed of honey research is presented in a context of known mechanism of formation of the stable ...

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

Advanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Dopamine, Chlorogenic Acid, and Quinones as Possible Cofactors of Increasing Adventitious Rooting Potential of In Vitro Krymsk 5 Cherry Rootstock Explants

Agronomy, 2022
In the present study, the effect of some not commonly used phenolic compounds was evaluated during the in vitro rooting stage of the cherry rootstock ‘Krymsk 5′ (P. fruticosa × P. lannesiana), in the absence or presence of auxin.

Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

Advanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,
