Imide and isatin derivatives as β-lactam mimics of β-lactam antibiotics [PDF]
, 2002 Activated γ-lactams, which are derivatives of succinimide, phthalimide and isatin with suitable elements of molecular recognition, have been synthesised as mimics of the ß-lactam antibiotics and their chemical and biological reactivity ...

Contact Dermatitis, Volume 94, Issue 5, Page 515-523, May 2026.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.

Advanced Functional Materials, Volume 36, Issue 28, 7 April 2026.A combinatorial library of dual‐functional antiviral oligomers incorporating N‐halamine and quaternary ammonium functionalities is developed for long‐lasting antiviral activity. The lead materials exhibit rapid and durable antiviral activity against SARS‐CoV‐2 variants and influenza H1N1, with 4 to 5 log reduction in viral copies at 5 mg mL−1 ...

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.

Beilstein Journal of Organic Chemistry, 2018 A practical three-step protocol for the assembly of triazolobenzodiazepine-fused diketopiperazines and hydantoins has been developed. The synthesis of these tetracyclic ring systems was initiated by an Ugi reaction, which brought together all necessary ...
