Advanced Synthesis &Catalysis, Volume 368, Issue 16, 18 August 2026.A Strecker‐type reaction of aromatic ortho‐diamines with various aldehydes and cyanide assembles the bicyclic amidine core of flavin‐derived heterocycles under mild conditions. Subsequent oxidation, radical or photochemical cyanation, carboxylation with CO2, and CO2‐mediated cyclization build the three‐ring alloxazine scaffold. This sequence provides a

Contact Dermatitis, Volume 95, Issue 2, Page 125-147, August 2026.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.

ChemMedChem, Volume 21, Issue 13, 14 July 2026.A series of 5‐nitroimidazole‐1,2,3‐triazole hybrids was synthesised and evaluated for antitrypanosomatid activity to assess their potential as treatments against leishmaniasis and trypanosomiasis. No notable in vitro activity against Leishmania was detected.

ChemMedChem, Volume 21, Issue 13, 14 July 2026.Nitrofuran‐based hydrazones derived from furagin are developed as dual inhibitors of thioredoxin reductase 1 and cancer‐associated carbonic anhydrases IX and XII. The series shows selective enzyme inhibition with reduced off‐target carbonic anhydrase (CA) I/II activity, while lead compound 7g exhibits potent TrxR1 inhibition and moderate anticancer ...

Applied 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.

Advanced 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 ...
