External Stimuli‐Activable Single‐Atom Nanozymes for Bioapplications

Small, EarlyView.
Stimuli‐activable single‐atom nanozymes (SANs) are reviewed from materials design to biomedical applications. We explain electronic‐structure tuning principles and synthesis strategies that maximize the responsiveness of metal active sites and supports to light, ultrasound, and magnetic fields.

Reactivity of the Iron Complexes with the Macrocyclic Ligand 5,5,7,12,12,14‐Hexamethyl‐1,4,8,11‐Tetraazacyclotetradecane (tet) Toward Dioxygen

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The complex [(tet a)FeII(OTf)2] reacts with dioxygen first to a superoxido intermediate and in a consecutive reaction to the corresponding iron–oxido complex. The reactions of the iron complexes [(tet a)FeII(OTf)2] and [(tet b)FeII](OTf)2 (tet = 5,5,7,12,12,14‐hexamethyl‐1,4,8,11‐tetraazacyclotetradecane) with dioxygen were investigated.

Enhancing antitumour response to proteasome inhibitors with inhibitors of insulin‐degrading enzyme, a new molecular vulnerability in multiple myeloma

British Journal of Pharmacology, EarlyView.
Inhibitors of insulin‐degrading enzyme boost PI cytotoxicity through an increased sensitivity of proteasome to PI inhibitors, induction of ISR, DNA damage and Myc down‐regulation. They overcome PI resistance in vitro and induce tumour regression in vivo.

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

Inhibition of α-, β-, γ-, and δ-carbonic anhydrases from bacteria and diatoms with N′-aryl-N-hydroxy-ureas

Journal of Enzyme Inhibition and Medicinal Chemistry, 2018
The inhibition of α-, β-, γ-, and δ-class carbonic anhydrases (CAs, EC 4.2.1.1) from bacteria (Vibrio cholerae and Porphyromonas gingivalis) and diatoms (Thalassiosira weissflogii) with a panel of N’-aryl-N-hydroxy-ureas is reported. The α-/β-CAs from V.

Quantitative Competition Binding of Fluorinated Ligands by Real‐Time 19F In‐Cell NMR to Assess Isoform Selectivity in Human Cells

Magnetic Resonance in Chemistry, Volume 64, Issue 6, Page 584-593, June 2026.
Real‐time in‐cell 19F NMR spectroscopy in a flow NMR bioreactor was used to monitor the binding of fluorinated compounds to three cytosolic carbonic anhydrase isoforms in living human cells. The simultaneous observation of the two ligands allowed for the quantitative ranking of their intracellular affinities by competition binding. This approach allows

Activation studies of the α- and β-carbonic anhydrases from the pathogenic bacterium Vibrio cholerae with amines and amino acids

Journal of Enzyme Inhibition and Medicinal Chemistry, 2018
The α- and β-class carbonic anhydrases (CAs, EC 4.2.1.1) from the pathogenic bacterium Vibrio cholerae, VchCAα, and VchCAβ, were investigated for their activation with natural and non-natural amino acids and amines.

Unravelling the Influence of Silicon Nanoparticles on Growth and Physiological Changes in Rice Under Cadmium Stress

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT Cadmium (Cd) is a toxic trace metal that causes severe environmental pollution and alters plants' physiological and biochemical responses. Although commercially synthesised silicon nanoparticles (SiNP) have been reported in alleviating biotic and abiotic stresses, the role of PV (photovoltaic) driven SiNP in modulating plant physio‐biochemical
