AzUlene‐Fused Polycyclic Aromatic Hydrocarbons: Synthesis, Structural, Optical, and Electrochemical Properties of Azuleno[2,1‐a]phenalenones

open access: yesChemistryEurope, EarlyView.
Delving into the synthesis of azulene‐fused polycyclic aromatic hydrocarbons, this article presents an effective route via Suzuki–Miyaura coupling and Brønsted acid‐mediated cyclization. It details unique optical properties, that is, UV/vis and fluorescence spectra, and electrochemical behavior, highlighting remarkable halochromism and electrochromism ...

Electrochemical Fabrication of Nanoparticles and Single‐Atom Catalysts via Cathodic Corrosion

open access: yesChemistry – A European Journal, EarlyView.
While cathodic corrosion can be detrimental to electrode surfaces, it has emerged as a powerful electrochemical method for fabricating nanoparticles and single‐atom catalysts from bulk wires. This mini‐review highlights recent advancements in cathodic corrosion‐based synthesis, focusing on its unique capabilities and the superior (photo ...

Optimization of Steroid Photochemistry and Its Application in the Synthesis of 5,6‐dihydro‐ophiopogonol A.

open access: yesChemistry – A European Journal, Accepted Article.
The photoreactivity of steroids represented a hot topic in the middle of the last century and in this project we “rediscover” it through the exploration of the photochemical behavior of D1‐3‐keto‐steroids. In terms of number of products obtained, the photochemistry of D1‐3‐keto‐steroids is less complicated than that of D4‐3‐keto‐ and D1,4‐3‐keto ...

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

open access: yesHepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

3,4,5‐Trifluorophenyldiazonium – a unique radical source for the visible light induced, catalyst‐free arylation of tyrosine residues in peptides

open access: yesChemistry – A European Journal, Accepted Article.
The direct radical arylation of tyrosine residues in peptides has been achieved under highly attractive conditions, requiring only the peptide substrate, a 3,4,5‐trifluorophenyldiazonium salt and irradiation with visible light. Being well‐balanced in its reactivity to form strong charge transfer complexes with the phenolic side chain, which are ...
