Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

A General Copper-Catalyzed Coupling of Azoles with Vinyl Bromides
A copper-catalyzed methodology for the coupling of vinyl bromides with azoles has been developed. This protocol uses a combination of 10 mol % of copper iodide and 20 mol % of ethylenediamine as catalyst.

Facile synthesis of functionalized spiro[indoline-3,2'-oxiran]-2-ones by Darzens reaction
A series of functionalized spiro[indoline-3,2'-oxiran]-2-ones was efficiently synthesized by Darzens reaction of phenacyl bromides with isatins both with N-alkyl groups and without N-substituent in the presence of potassium carbonate as a base catalyst ...

NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Copper-Catalyzed Trifluoromethylation of Alkyl Bromides
Copper oxidative addition into organohalides is a challenging two-electron process. In contrast, formal oxidative addition of copper to Csp2 carbon–bromine bonds can be accomplished by employing latent silyl radicals under photoredox conditions.

TGF‐β1 stimulation downregulates lysosomal channel TRPML1 in pulmonary fibroblasts. The TRPML1 agonist ML‐SA5 suppressed fibroblast‐to‐myofibroblast activation and collagen production. Mechanistically, ML‐SA5 inhibited mTOR phosphorylation, restored autophagic flux, and its effects were enhanced by rapamycin (mTOR inhibitor) and reversed by MHY1485 ...

Reductive Cross-Coupling of Nonaromatic, Heterocyclic Bromides with Aryl and Heteroaryl Bromides
Reductive cross-coupling allows the direct C–C bond formation between two organic halides without the need for preformation of an organometallic reagent.
