Synthesis, Characterization and Electrochemical Properties of Tri‐ and Tetranuclear CoIII‐Oxo Complexes

European Journal of Inorganic Chemistry, Accepted Article.
Heterocubane‐type complexes containing a central [CoIII4O4] core have received increasing interest as surface cut‐outs of active spinel‐type Co3O4 water splitting catalysts. We here report the synthesis of a series of tetranuclear ([Co4O4(O2CR)4(py)4] (R = Me 1, Et 2, n‐Pr 3)) and trinuclear Co(III) carboxylate complexes [CoIII3(μ3‐O)(μ2‐OH)(O2CR)3(py ...

Catalytic Dehydrogenation of Lauric Acid and a Potential Use in Polyester Synthesis

European Journal of Lipid Science and Technology, EarlyView.
A three‐step reaction sequence was developed to synthesize renewable lauric acid–based dimethyl esters. The sequence consists of a catalytic dehydrogenation of saturated fatty acids with molecular oxygen as oxidant, an esterification with methanol, and a dimerization reaction with dithiols via thia‐Michael addition.

Design, Synthesis and Anti-fibrosis Activity Study of N1-Substituted Phenylhydroquinolinone Derivatives

Molecules, 2012
Pirfenidone (5-methyl-1-phenyl-2(1H)-pyridone, PFD) is a small-molecule compound acting on multiple targets involved in pathological fibrogenesis and is effective to increase the survival of patients with fibrosis, such as idiopathic pulmonary fibrosis ...

One‐Step Aqueous Synthesis of Glycosyl Pyridinium Salts, Electrochemical Study, and Assessment of Utility as Precursors of Glycosyl Radicals Using Photoredox Catalysis

ChemistryOpen, EarlyView.
Unprotected glycosyl pyridinium salts may be accessed in a single step from the corresponding unprotected sugar in aqueous solution. Whilst meta‐ and para‐substitution is well tolerated, ortho substitution of the N‐heterocycle inhibits product formation. Electrochemical studies revealed reduction potentials in the range of −0.9 to −1.4 V.

Harnessing Molecular and Bioactivity Network Analysis to Prioritize Antibacterial Compound Isolation From Ant‐Associated Fungi

Phytochemical Analysis, EarlyView.
ABSTRACT Introduction Antimicrobial resistance is a global public health problem that requires the development of new bioactive compounds. In this context, metabolomic analyses can expedite the research of fungal metabolites as a valuable resource. Objectives To investigate the metabolic profiles and isolate antibacterial compounds from micromycetes ...

Nicotinamide Riboside Supplementation Benefits in Patients With Werner Syndrome: A Double‐Blind Randomized Crossover Placebo‐Controlled Trial

Aging Cell, EarlyView.
Nicotinamide riboside improved arterial stiffness (cardio–ankle vascular index), reduced skin ulcer area, and showed a trend toward mitigating heel pad thinning in patients with Werner syndrome, with no serious adverse events. Metabolomic analysis revealed a significant decrease in creatinine, suggesting a potential suppression of renal functional ...

Chemical constitutions in the Colour Index™: A century of colourant classification

Coloration Technology, EarlyView.
Abstract This article details how the Colour Index™ (CI) system categorises and unambiguously labels commercial dyes and pigments based upon their chemical constitutions. It outlines the current process by which colourants that are new to the market find a place within CI and acquire generic identifiers.

Designing Enzymatic Reactivity with an Expanded Palette

ChemBioChem, Volume 26, Issue 11, June 3, 2025.
Innovation in biocatalysis is rapidly increasingly the diversity of catalytic reactivity that can be mediated by enzymes, addressing a key bottleneck for their widespread adoption in industrial chemical synthesis. A key approach to this is building enzymes with unnatural catalytic components that provide an expanded palette with new possibilities for ...

Noninvasive Evaluation of Prolonged‐Release Pirfenidone in Compensated Liver Cirrhosis. ODISEA Study, a Randomised Trial

Liver International, Volume 45, Issue 6, June 2025.
ABSTRACT Background Advanced liver fibrosis (ALF) predicts an adverse prognosis in chronic liver disease. In addition to etiological treatment, a new approach to stop or reverse residual fibrosis is desirable. Objective To assess the efficacy and safety of prolonged‐release pirfenidone (PR‐PFD) versus placebo in compensated cirrhosis.
