Naphthyl hydrazone anchored with nitrosalicyl moiety as fluorogenic and chromogenic receptor for heavy metals (Ag+, Hg2+) and biologically important F− ion and its live cell imaging applications in HeLa cells and Zebrafish embryos

Positional Isomeric Symmetric Dipodal Receptors Dangled with Rotatable Binding Scaffolds: Fluorescent Sensing of Silver Ions and Sequential Detection of l-Histidine and Their Multifarious Applications

“…During the binding of probes with Ag + ion, there was a high enhancement in fluorescence intensity with an 8 nm shift as the probes with a Ag + complex gave a strong fluorescence emission (turned on), which was observed under 365 nm UV illumination aided by a color change from a colorless solution to a vivid blue color (Figure S21). Many previous works showed interference of other metal ions during the sensing of Ag + by fluorescent probes. ,− In our situation, as shown in Figure S24, three probes showed no significant anti-interference with other metal ions while detecting Ag + ions under identical conditions. As a result, all three probes could hardly detect the Ag + metal ion in DMSO–H 2 O solutions (1:1 v/v, HEPES 50 mM, pH = 7.4) via fluorescence spectroscopy.…”

Structure investigation, density functional theory, and biostudy of synthesized dihydrazone incorporating isatin moiety and its homo‐bimetallic complexes

“…The difference value (Δ = ν as (NO 3 À ) À ν s (NO 3 À = 85 cm À1 ) is small indicating to the unidentate nature of the nitrate group. [84,86] In sulfato complex (7), there are three bands at 1,119, 1,050, and 954 cm À1 attributing to the unichelated sulfate group which is confirmed by has conformity with its low conductivity value. [84,87] In case of UO 2 2+ complex (8), there is a new band at 963 cm À1 , which can be attributed to the ν(O═U═O).…”

“…Accordingly, the hydrazonic chelators and their chelated compounds have been intensely utilized in coordination chemistry because of their chelating capabilities, physiological activities, and broad range of applications in several fields like analytical, clinical, biological, pharmacological, industrial chemistry, biomedical chemical, and wastewater remediation. [4][5][6][7] In this respect, various hydrazonic chelators and their chelated compounds have been stated to have important biological and pharmacological activities involving antimalarial, [8] enzyme inhibitors, [9][10][11][12] antimicrobial, antifungal, antibacterial, [13][14][15] antitrypanosome, [16] anticancer, [17,18] antidiabetic, [19,20] antitumor, [6,21,22] antiinflammatory, [10,23] antiviral, [10,24] and antioxidant. [25,26] Also, some acyl-hydrazone derivatives have been utilized in the Alzheimer's disease treatment, radical scavenging, and myeloperoxidase/acetylcholinesterase inhibition.…”
