Biosensors, Год журнала: 2024, Номер 14(5), С. 244 - 244

Опубликована: Май 13, 2024

A novel indolium-based fluorescent probe for the detection of CN− was developed based on conjugation 1, 2, 3, 3-Tetramethyl-3H-indolium iodide and 2-acetyl benzothiophene. The introduction external caused a nucleophilic attack to quaternary amine salt structure in resulted departure ions steric rotation index group, which fluorescence quenching. titration experiments showed that had rapid qualitative quantitative analysis capabilities CN−. Moreover, relevant biocompatibility also demonstrated potential application value probe.

The cholinergic deficits and deposition of β-amyloid (Aβ) species are regarded as the key events contributing to progression Alzheimer's disease (AD). Herein, a series novel donor-acceptor architecture-type potential theranostic agents were designed, synthesized, evaluated for their against cholinesterase (ChE) enzymes detection Aβ species, which primary targets in development therapeutics AD. optimal compound/probe 18 containing benzothiazolium fluorophore with bifunctional electron-donating N-aryl piperazine scaffold exhibited potent inhibitory activities acetylcholinesterase (AChE; IC50 = 0.172 ± 0.011 μM) butyrylcholinesterase (BuChE; 1.376 0.141 μM). Measurement fluorescence properties showed that probe emission maxima (λem) >610 nm dimethyl sulfoxide (DMSO) >590 PBS, suitable imaging.

Abstract A hemicyanine-based colorimetric and fluorometric sensor, 2-(2-(2,3,5,6,8,9-hexahydrobenzo[b][1,4,7,10]tetraoxacyclododecin-12-yl)vinyl)-3,3-dimethyl-1-propyl-3H-indol-1-ium iodide (MH-5), was developed synthesized to detect Li + CN − ions in DMSO-PBS buffer solution (10 mM, pH 7.25, v/v 1:9). MH-5 displayed a rapid highly selective response both , indicated by distinct color change from pink pale the presence of colorless upon detection, without interference other cations or anions. The interaction mechanisms with were investigated using various analytical techniques, including 1 H NMR, ESI–MS, FT-IR spectroscopy, Job’s plot analysis. These studies suggest that is detected through nucleophilic addition indolium moiety MH-5, while detection occurs via coordination oxygen atoms crown ether structure. fluorescence-based limits for determined be 0.150 µM 0.154 µM, respectively. Additionally, evaluated living cells, demonstrating effective cell penetration reliable potential bio-imaging applications. Graphical
