Synthesis, antimicrobial evaluation and docking study of triazole containing triaryl-1H-imidazole [PDF]

open access: yes, 2019
An efficient route for the synthesis of triazole containing triaryl-1H-imidazole (3a–3r) was achieved involving multicomponent condensation of triazole aldehydes, ammonium acetate and 1,2-dicarbonyl compounds in glacial acetic acid.

Imidazole-Functionalized Y‑Shaped Push–Pull Dye for Nerve Agent Sensing as well as a Catalyst for Their Detoxification [PDF]

open access: yes
A Y-shaped push–pull dye (1) with N,N-dimethylanilino donors and a benzonitrile acceptor connected via an imidazole-based π-conjugated spacer was designed. It showed a dark yellow color in solution due to facile intramolecular charge-transfer interaction,

Dual role of imidazole as activator/inhibitor of sweet almond (Prunus dulcis) β-glucosidase

open access: yesBiochemistry and Biophysics Reports, 2017
The activity of Prunus dulcis (sweet almond) β-glucosidase at the expense of p-nitrophenyl-β-d-glucopyranoside at pH 6 was determined, both under steady-state and pre-steady-state conditions. Using crude enzyme preparations, competitive inhibition by 1–5
