Abstract In the face of escalating challenges microbial resistance strains, this study describes design and synthesis 5‐({1‐[(1 H ‐1,2,3‐triazol‐4‐yl)methyl]‐1 ‐indol‐3‐yl}methylene)thiazolidine‐2,4‐dione derivatives, which have demonstrated significant antimicrobial properties. Compared with minimum inhibitory concentrations (MIC) values ciprofloxacin on respective compounds 5a , 5d 5g 5l 5m exhibited potent antibacterial activity MIC ranging from 16 to 25 µM. Almost all synthesized showed...
There is burgeoning interest among supramolecular chemists to develop novel molecular systems detect biogenic amines and bio-thiols in aqueous non-aqueous media due their potential role biological processes. Biogenic are biologically important targets because of involvement the energy metabolism human requirement met through food nutrition. However, increasing instances serious health problems toxicity have raised quality nowadays. been frequently considered as markers or primary parameters...
A novel vitamin B6 Schiff base analog (L) was synthesized by combining cofactor pyridoxal with 2-aminophenol. Receptor L displays a color change detectable the naked-eye from yellow to red in presence of fluoride and acetate due formation hydrogen bonding host–guest complexes 1 : stoichiometry. Importantly, receptor showed fluoride-selective 'turn-on' fluorescent response detection limit (3σ) 7.39 × 10−8 M.
A benzothiazole derivative linked "off-on" multi-responsive and selective chemosensor has been synthesized evaluated for cation recognition properties. The receptor shows a high sensitivity selectivity Zn(2+) through 'turn-on' fluorescence response over the other tested cations with detection limit as low 0.67 μM. was successfully applied of in live HeLa cells. Then, complex also used cyanide recognition.
A highly selective colorimetric as well fluorescence sensor for Fe(<sc>iii</sc>) and Cu(<sc>iii</sc>) in 99% aqueous medium.
A novel fluorescent receptor L was synthesized by Schiff base condensation of 1-pyrenemethylamine with the vitamin B6 cofactor pyridoxal. The is highly selective and sensitive towards Zn2+ ions among other tested metal ions. Upon interaction Zn2+, showed a distinct fluorescence enhancement at 485 nm due to excimer formation leading colour change from blue bluish-green. Subsequently, when in situ generated ZnL2 complex interacted various anions amino acids, addition H2PO4- cysteine reinstated...
In this paper, a new Th4+ ion-selective chromogenic sensor (L) was developed by reacting 1,10-phenanthroline-2,9-dicarbohydrazide with 2-hydroxy naphthaldehyde. The sensing ability of L toward investigated in solution and paper strips loaded using spectrophotometric colorimetric methods. selective interaction examined various f-metal ions other selected metal from s-block d-block elements. Results show that the method solution-phase dimethyl sulfoxide/H2O (7:3, v/v) strip methods, naked-eye...
A new optical chemosensor N1 was designed and synthesized by condensing 4-chloro-7-nitrobenzofurazan with 2-aminophenylbenzimidazole. In CH3OH : H2O (1 1, v/v) medium, sensor exhibited high selectivity sensitivity towards Cu2+ Hg2+ ions showing a distinct colour change from pale yellow to pink due the internal charge transfer occurring between Cu2+/Hg2+ upon complexation in 1 stoichiometry. Also, binding of resulted absorption bands at 540 nm 375 concurrent disappearance 485 321 nm. Using...
Abstract This communication demonstrates a rapid, reproducible and highly selective colorimetric nanosensor for the detection of Cr 3+ ions in aqueous medium using functionalized gold nanoparticles. The AuNPs were obtained three steps: (i) citrate capped Cit‐AuNPs prepared by standard procedure, (ii) thiolated Schiff base CAPLP was generated in‐situ reacting vitamin B 6 cofactor pyridoxal 5′‐phosphate cysteamine, then (iii) decorated over surface via ligand exchange method yielding spherical...
