Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.Various substituted chromane‐2‐carboxamides were successfully deracemized by employing a chiral benzophenone (BP, 10 mol%) as photocatalyst and an achiral thiol as additive (20 mol%). The method was applied to the concise enantioselective synthesis of five active pharmaceutical ingredients.

Contact Dermatitis, EarlyView.The overall prevalence of sensitization to FA/FRs was 1.9% (48/2592). ACD was diagnosed in 37.5% (18/48), comprising non‐occupational ACD (83.3%) and occupational ACD (16.7%). FA 1%–2% aq. failed to detect FR sensitisation in 31.9% (n = 15/47) and FR‐induced ACD in 35.3% (n = 6/17) of patients.

ADAM17 and its proteolytic targets in disease pathogenesis
The 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 ...

Advanced Synthesis &Catalysis, Volume 368, Issue 6, 17 March 2026.Selective late‐stage modification of N‐terminal phenylalanine short peptides is achived by visible‐light initiated reaction with N‐iodoimides in a debenzylation–amination process. This metal‐free method permits the incorporation of N‐containing heterocycles into the α‐position of the peptide backbone.
