Novel Bioactive Multifunctional Polyphenols: A Chemo‐Enzymatic Approach

open access: yesChemistry – A European Journal, EarlyView.
One‐step synthesis of complex alkyl oxystilbenin glucosides (6‐47% yield) in alcoholic medium. Switching to ter‐BuOH as solvent afforded δ‐Viniferin diglucoside, with high selectivity and high yield (> 90%), that can be upgraded by enzymatic esterification to alkyl δ‐Viniferin diglucosides.

Study of Uncatalyzed and Micellar‐Catalyzed Oxidative Degradation of Amoxicillin by Colloidal MnO2: Experimental Optimization and Mechanistic Aspects

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The absorption spectra of amoxicillin degradation by colloidal MnO2 in the presence and absence of surfactants. Herein, the oxidative degradation of amoxicillin (AMX) by water‐soluble colloidal MnO2 is investigated spectrophotometrically at 298 K in both uncatalyzed and nonionic micellar‐catalyzed media (Triton X‐100 and Brij‐35).

In vivo kinetics of [bêta]-glucosidase towards glucovanillin and related phenolic glucosides in heat-treated vanilla pod (Vanilla planifolia, Orchidaceae) [PDF]

open access: yes, 2010
Introduction . The traditional curing of vanilla pods includes “killing” and sweating steps when pods are exposed to heat (35–65 °C) for various lengths of time. Although it is known that liberation of vanillin and other phenolics from their non-aromatic
