Synthesis, spectral properties, chemical descriptors and light harvesting studies of a new bioactive azo imidazole compound

Synthesis, characterization and computational study on potential inhibitory action of novel azo imidazole derivatives against COVID-19 main protease (Mpro: 6LU7)

“…In the 1 H NMR spectrum of L1-L6, a signal of slightly broad singlet peak appearing in the range δ 12.80–13.80 ppm can be assigned to OH proton and a singlet peak at δ14.2 ppm in the 1 H NMR spectra of L5 can be assigned to COOH group [47] . Similarly, the signal appearing in the range δ 8.54–8.88 ppm can be attributed for CH N proton of the compounds L1-L6 [ 47 , 57 , 59 , 66 ]. A set of three singlet peaks for imidazole ring NCH proton for all the synthesized derivatives appeared in the range 7.62–7.66 ppm, 7.75–7.79 ppm and 9.13–9.20 ppm respectively.…”

“…Synthesis of azo imidazole derivatives has been achieved by following the literature procedure given elsewhere [ 38 , [57] , [58] ]. 5 mmol of 1-(2-Aminoethyl)−3-methylimidazolium hexafluoro-phosphate in absolute ethanol was added to an ethanolic solution of azo-coupled o-vaniline precursors (5 mmol) during a period of 10 min.…”

Exploration of inhibitory action of Azo imidazole derivatives against COVID-19 main protease (Mpro): A computational study

“…azo imidazole derivatives has been synthesized by following the literature procedure given elsewhere [37, [62] , [63] , [64] , [65] . In a typical synthetic procedure 1-(2-Aminoethyl)−3-methylimidazolium hexafluoro-phosphate, ([2aemim] [PF 6 ]) (5 mmol) in absolute ethanol was pour in a stirring solution of azo-coupled o-vaniline precursors (5 mmol) in 20 ml of absolute ethanol during a period of 10 min.…”

Conformational analysis and quantum descriptors of two new imidazole derivatives by experimental, DFT, AIM, molecular docking studies and adsorption activity on graphene

“…HMY and HMM are prepared according to reported protocol [ 21 , 22 ]. Perkin Elmer spectrometer was used for FT-IR spectrum ( Figure 2 ) and Raman spectrum ( Figure 3 ) of the sample were using Bruker UFS 66V model interferometer using Nd:YAG laser source.…”

“…Mary et al. reported a number of imidazole derivative's spectroscopic studies [ 17 , 18 , 19 , 20 , 21 , 22 , 23 ]. In literature, broad research has been reported on graphene activity [ 24 , 25 , 26 , 27 , 28 , 29 ].…”
