Preparation of 5-Bromo-2-naphthol: The Use of a Sulfonic Acid as a Protecting and Activating Group

Molbank, 2009
The preparation of 5-bromo-2-naphthol (4) in three steps from 5-amino-2-naphthol (1) is described. A sulfonic acid group is introduced at the 1-position as an activating and protecting group for the Sandmeyer reaction.

Comments to the Article Wu Y, Völler S, Goulooze SC, et al. A Novel Maturation Equation for Hepatic Clearance Across Preterm, Term Neonates, Children, and Adults: Application to Paracetamol and Its Metabolite. J Clin Pharmacol. 2025;65(12):1829‐1843. doi: 10.1002/jcph.70080. PMID: 40910464; PMCID: PMC12649303

The Journal of Clinical Pharmacology, Volume 66, Issue 5, May 2026.
Abstract A recent article in this journal by Wu et al presented a comprehensive model for the maturation of paracetamol clearance from birth to adulthood using pooled plasma and urinary data of the parent drug and its metabolites from 298 subjects. The modeling showed that the oxidative bioactivation to hepatotoxic metabolite N‐acetyl‐p‐benzoquinone ...

The barley–malt–beer chain: A process and food safety approach

JSFA reports, Volume 6, Issue 5, Page 144-159, May 2026.
Abstract This review addresses the current state of knowledge on the barley–malt–beer chain and its main physical, chemical, and microbiological contaminants, with particular emphasis on spoilage microorganisms and their toxic metabolites. The barley–malt–beer production chain represents a mature and globally relevant agro‐industrial sector that ...

Sulfonated, Disulfide‐Bridged Polymer Networks for Atmospheric Water Harvesting

Small, Volume 22, Issue 29, 22 May 2026.
Atmospheric water harvesting is a promising solution to the water crisis. Here, disulfide‐containing hyper‐crosslinked‐style polymers are prepared by combined Friedel–Crafts alkylation and thiol self‐condensation. Exhibiting exceptional uptake capacities, the polymers demonstrate dynamic bonding behavior.

Phase behavior and nanomechanical mapping of block ionomer complexes

, 2013
Block ionomer complexes SSEBS-c-PCL were prepared, as a consequence of proton transfer from the sulfonic acid of sulfonated polystyrene-block- poly(ethylene-ran-butylene)-block-polystyrene (SSEBS) to the tertiary amine of a tertiary amine terminated poly(

Farnesoid x Receptor Deficiency Promotes Hepatocytic Injury in Cyp2c70‐Deficient Mice With a Human‐Like Bile Acid Composition

Liver International, Volume 46, Issue 5, May 2026.
ABSTRACT Background and Aims Loss‐of‐function mutations in bile acid (BA)‐activated farnesoid x receptor (FXR/NR1H4) cause severe neonatal liver pathology in humans, earlier referred to as progressive familial intrahepatic cholestasis type 5 (PFIC5). However, Fxr‐deficient mice do not develop early‐onset liver disease, possibly due to the predominance ...

Processing and release of endogenous immunogenic peptide signals

The Plant Journal, Volume 126, Issue 3, May 2026.
SUMMARY In both animals and plants, small secreted peptides known as cytokines and phytocytokines mediate local and systemic communication during immune and stress responses. These signaling molecules are typically synthesized as inactive precursors that require proteolytic processing to become active.
