Chelation of specific metal ions imparts coplanarity and fluorescence in two imidazo[1,2-a]pyridine derivatives: Potential chemosensors for detection of metal ions in aqueous and biosamples
interacting metal ions. Other trivalent metal ions (including Bi3+ and In3+) and common divalent metal ions (including Hg2+ and Cd2+) fail to form any complex with 1 or 2, and they do not interfere in the detection of Zn2+, Al3+, Fe3+ or Cr3+ ions. Noninterference of other metal ions renders 1 and 2 suitable for the detection of fungal cells contaminated with Zn2+, Al3+, Fe3+ or Cr3+ ions.

Abstract In this work, various imidazo[1,2-a]pyridineslinked to carbamate moiety were designed, synthesized, and evaluated for their α-glucosidase inhibitory activity. Among synthesized compounds, 4-(3-(tert-Butylamino)imidazo[1,2-a]pyridin-2-yl)phenyl p-tolylcarbamate (6d) was the most potent compound (IC50 = 75.6 µM) compared with acarbose as the reference drug (IC50 = 750.0 µM).

activities. The most direct way of obtaining this nucleus is the Groebke–Blackburn–Bienaymé three-component reaction (GBB-3CR) between aminopyridines, aldehydes, and isocyanides under both Lewis and Brønsted acid catalysis. However, several catalysts for this reaction have major drawbacks such as being expensive, extremely dangerous, strong oxidizing, and even explosive. In this scenario, heteropolyacids
