The Prevalence of Contact Allergy to Formaldehyde and Formaldehyde Releasers: A Systematic Review and Meta‐Analysis

open access: yesContact Dermatitis, EarlyView.
ABSTRACT Formaldehyde and its releasers are common preservatives and potent sensitizers. This meta‐analysis aimed to estimate the prevalence of formaldehyde contact allergy and allergy to its five most common releasers among dermatitis patients. Two authors independently searched PubMed, Embase, and Web of Science from inception to 30th September 2025.

Palladium Catalyzed C‑Arylation of Amino Acid Derived Hydantoins

open access: yes, 2015
Palladium­(II) trifluoroacetate (5 mol %) catalyzes the C-arylation of N,N-disubstituted hydantoins by aryl iodides in good yield. The reaction proceeds through base-promoted enolization of the amino acid derived hydantoins, and the resulting 5,5 ...

ADAM17 and its proteolytic targets in disease pathogenesis

open access: yesThe FEBS Journal, EarlyView.
ADAM17 as a multifunctional sheddase with contrasting roles across inflammatory, metabolic, cardiovascular, and neoplastic diseases. Through regulated activation by iRhom, iTAP/FRMD8, and tetraspanins, ADAM17 cleaves diverse membrane ligands and receptors, thereby promoting inflammation, fibrosis, obesity, insulin resistance, and tumor progression ...

The synthesis of 5-substituted hydantoins

open access: yes, 2008
The Bucherer-Bergs reaction is a classical multi-component reaction that yields hydantoins, which can be hydrolysed to afford α-amino acids. Hydantoins have many uses in modern organic synthesis, and this moiety has been included in a number of ...

Synthesis, Electrochemistry, In Vitro Antiprotozoal Efficacy and Mechanistic Study of Novel ‘Ferrantoin’ and Related Derivatives

open access: yesApplied Organometallic Chemistry, Volume 40, Issue 7, July 2026.
1,2‐Disubstituted ferrocene analogues bearing hydantoin or rhodanine synthons were synthesised and assessed for antitrypanosomatid activity. An antileishmanial early lead, analogue 23, acting through ROS generation and hence oxidative stress, was uncovered.

Enantioselective Tandem Povarov/Urech–Read Reaction for the Synthesis of Dihydroquinoline/Hydantoin Hybrids

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
Herein, an organocatalytic asymmetric synthesis of dihydroquinoline/hydantoin hybrids is described. The synthetic protocol involves a tandem reaction comprising a phosphoric acid–catalyzed initial Povarov dimerization of in situ generated imine/enamine mixtures under tautomeric equilibrium, followed by a Urech–Read reaction of the 1,2‐dihydroquinoline ...
