Antinociceptive and Anti‐inflammatory Effect of Nicandrin B Isolated From Datura ferox in Zebrafish

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Nicandrin B (Nic B), a withanolide isolated from Datura ferox leaves, was investigated for its antinociceptive and anti‐inflammatory effects in adult zebrafish (Danio rerio). Animals treated with Nic B (4, 20, and 40 mg/kg) showed no toxicity and maintained normal locomotor activity.

Mucoadhesive Polyvinyl Alcohol Film Containing Fridericia chica Extract for Mucositis Treatment: Pharmacological Evaluation and Active Compounds Release

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Oral mucositis is a frequent and painful complication of cancer therapy with limited effective options. This study evaluated a mucoadhesive polyvinyl alcohol (PVA) film containing 2.5% Fridericia chica extract as a novel strategy. The formulation was characterized for antioxidant activity, phenolic and flavonoid content, and reactive species ...

Gold‐Dithiocarbamato Glycoconjugates as Potential Anticancer Agents: Design, Physico‐Chemical Characterization, and In Vitro Biological Activity

open access: yesChemBioChem, EarlyView.
Metal‐dithiocarbamato glycoconjugates based on gold(III), gold(I)‐phosphino, and gold(I)‐carbene scaffolds are here investigated as potential anticancer agents. Contrary to expectations, they induce cell death by acting at the extracellular level rather than targeting overexpressed glucose transporters.

Cobalamin‐Dependent Aryl Methyl Ether O‐Demethylases: Promising Enzymes for Biocatalytic Applications from Lignin Valorization to Organic Synthesis

open access: yesChemCatChem, EarlyView.
Cobalamin‐dependent aryl methyl ether O‐demethylases have high potential for biocatalytic applications, including lignin valorization and synthetic chemistry. In this review, we provide a detailed overview of such O‐demethylase systems identified to date from various microorganisms, including their mechanism, substrate scope and selectivity, and ...

Evidences of the Stabilization for Weeks of the Benzyl Cation in Zeolites

open access: yesChemistryEurope, EarlyView.
The benzyl cation is plausibly formed inside zeolites after rearrangement of individually isolated tropylium cations at room temperature. The benzyl cation–entrapped zeolite is stable for weeks without any storage precaution, and a solid–state 13C nuclear magnetic resonance spectrum of this iconic carbocation could be recorded.
