In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Anti-Escherichia Coli Non-Pathogenic Strain Activity Of Complex Compound Based On Copper(II) And 2,4,5-triphenyl-1h-Imidazole, published in 2021, which mentions a compound: 484-47-9, Name is 2,4,5-Triphenylimidazole, Molecular C21H16N2, Computed Properties of C21H16N2.
The complex of Copper(II) binding 2,4,5-triphenyl-1H-imidazole ligand is a new copper complex and exhibits therapeutic properties to bacteria. The present observation is focused on anti-Escherichia coli non-pathogenic strain using disk diffusion method. Copper(II)-2,4,5-triphenyl-1H-imidazole complex compound showed anti-Escherichia coli non-pathogenic strain activity with a range of inhibition zone 14.51-17.37 mm and compared with free metal Cu(II) less reactive with a range of inhibition zone 10.57-27.16 mm, but more no toxic in the Vero cells with CC50 44.74 Μg/mL.
Although many compounds look similar to this compound(484-47-9)Computed Properties of C21H16N2, numerous studies have shown that this compound(SMILES:C1(C2=CC=CC=C2)=NC(C3=CC=CC=C3)=C(C4=CC=CC=C4)N1), has unique advantages.
