Imidazoles as Potential Anticancer Agents: An Update on Recent Studies
Molecules, 2021 Nitrogen-containing heterocyclic rings are common structural components of marketed drugs. Among these heterocycles, imidazole/fused imidazole rings are present in a wide range of bioactive compounds.

Cholinesterase-like organocatalysis by imidazole and imidazole-bearing molecules [PDF]
Scientific Reports, 2017 AbstractOrganocatalysis, which is mostly explored for its new potential industrial applications, also represents a chemical event involved in endogenous processes. In the present study, we provide the first evidence that imidazole and imidazole derivatives have cholinesterase-like properties since they can accelerate the hydrolysis of acetylthiocholine

Electrochemically Induced Synthesis of Imidazoles from Vinyl Azides and Benzyl Amines
Molecules, 2022 An electrochemically induced synthesis of imidazoles from vinyl azides and benzyl amines was developed. A wide range of imidazoles were obtained, with yields of 30 to 64%.

Electric deflection of imidazole dimers and trimers in helium nanodroplets: Dipole moments, structure, and fragmentation [PDF]
Journal of Chemical Physics v.153, 081101 (2020), 2020 Deuterated imidazole (IM) molecules, dimers and trimers formed in liquid helium nanodroplets are studied by the electrostatic beam deflection method. Monitoring the deflection profile of (IM)D+ provides a direct way to establish that it is the primary product of the ionization-induced fragmentation both of (IM)2 and (IM)3.

Raman Scattering Spectra of Boron Imidazolate Frameworks Containing Different Magnetic Ions [PDF]
, 2023 We present a Raman scattering spectroscopic study of boron imidazolate metal-organic frameworks (BIFs) with three different magnetic metal ions and one non-magnetic in a wide frequency range from 25 to 1700 cm$^{-1}$, which covers local vibrations of the linkers and well as collective lattice vibrations. We show that the spectral region above 800 cm$^{-

Characterizing and contrasting structural proton transport mechanisms in azole hydrogen bond networks using ab initio molecular dynamics [PDF]
J. Phys. Chem. Lett. 2021, 12, 36, 8749-8756, 2021 Imidazole and 1,2,3-triazole are promising hydrogen-bonded heterocycles that conduct protons via a structural mechanism and whose derivatives are present in systems ranging from biological proton channels to proton exchange membrane fuel cells. Here, we leverage multiple time-stepping to perform ab initio molecular dynamics of imidazole and 1,2,3 ...
