Investigations into the characterization, degradation, and applications of biodegradable polymers by mass spectrometry

open access: yesMass Spectrometry Reviews, EarlyView., 2023
Abstract Biodegradable polymers have been getting more and more attention because of their contribution to the plastic pollution environmental issues and to move towards a circular economy. Nevertheless, biodegradable materials still exhibit various disadvantages restraining a widespread use in the market.

Cytoprotection by prostaglandins

open access: yesGastroenterology, 1979
Prostaglandins (PG) are a group of ZO-carbon oxy- genated fatty acids that are present in most mamma- lian cells and tissues. Approximately 20 of these chemicals have been identified in tissues and body fluids, whereas hundreds have been synthesized as analogs or derivatives of the natural PG.

Advances in Diclofenac Derivatives: Exploring Carborane‐Substituted N‐Methyl and Nitrile Analogs for Anticancer Therapy

open access: yesChemMedChem, EarlyView.
By N‐methylation, the intramolecular lactam formation in carborane‐substituted diclofenac analogs is prevented, yielding a series of open‐chain derivatives alongside with their phenyl analogs exhibiting anticancer activity and thus offering a promising avenue for future drug development. This study explores the anticancer potential of N‐methylated open‐

Synthesis and Biological Evaluation of Bicyclic Pyrazolines with Promising Antimicrobial Activities

open access: yesChemMedChem, EarlyView.
Continuous flow technology is exploited for the generation of bicyclic pyrazolines via photo‐click reactions. These heterocyclic species contain a valuable 3D scaffold along with a polar succinimide moiety. Subsequent antimicrobial testing reveals that halogenated moieties such as chlorine atoms and trifluoromethoxy groups enhance the potency of these ...

Carborane‐Based Analogs of Celecoxib and Flurbiprofen, their COX Inhibition Potential, and COX Selectivity Index

open access: yesChemMedChem, EarlyView.
Eight nido‐ and ortho‐carborane compounds based on celecoxib and flurbiprofen were synthesized and their COX inhibition was determined. The deboronation of the di‐substituted celecoxib derivative results in a switch from COX‐1 inhibitory preference to COX‐2 inhibition.

Synthesis of 19‐Hydroxyarachidonic Acid by Fungal Peroxygenases: An Experimental and Computational Study

open access: yesChemSusChem, Accepted Article.
Hydroxylated derivatives of arachidonic acid play crucial roles in physiology and inflammation response, with distinct biological effects for (R)‐ and (S)‐enantiomers, highlighting their pharmaceutical relevance. Here, we harness recombinant unspecific peroxygenases (UPOs)—from the fungi Coprinopsis cinerea (rCciUPO) and Agrocybe aegerita (rAaeUPO ...
