Low-toxicity copper corrosion inhibitors

The efficiency of various imidazole derivatives as corrosion inhibitors for copper in hydrochloric and sulfuric acids (HCl and H2SO4) was investigated. Electrochemical measurements showed the organic compounds investigated have fairly good inhibiting properties, except for 4-methyl-5-imidazole-carbaldehyde in HCl. Protecting properties of most imidazole derivatives were close to those of commercial inhibitors for copper. Evaluation of the toxicity of the water solutions on the biological system for treatment of waste water – as measured in regard to chemical oxygen demands (COD), aerobic, and anaerobic toxicity – showed the tested inhibitors have relatively low toxicity.

Reference of 288-32-4, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 288-32-4.

QSAR studies on hetaryl imidazoles derivatives as novel dual inhibitors of vascular endothelial growth factor receptors I and II

The QSAR studies have been carried out on 19-hetaryl imidazoles derivatives, which were reported as inhibitor of vascular endothelial growth factor receptors (VEGFR). The present study was undertaken to determine the physico chemical parameters, which govern the anticancer activity of the given series of drug molecules. The best QSAR model thus obtained, have high statistical significance (> 99.9 %) and moderate correlation coefficient (r = 0.85) led us to know that the activity of these compounds is mainly influenced by substitutions (R) done at meta position of benzene ring and presence of 4-pyridine group at Ar position is found to be important for activity of given series of drug molecules.

Assessment of effective imidazole derivatives against SARS-CoV-2 main protease through computational approach

Because of the fast increase in deaths due to Corona Viral Infection in majority region in the world, the detection of drugs potent of this infection is a major need. With this idea, docking study was executed on eighteen imidazole derivatives based on 7-chloro-4-aminoquinoline against novel Coronavirus (SARS-CoV-2). In this study, we carried out a docking study of these molecules in the active site of SARS-CoV-2 main protease. The result indicate that Molecules No 3, 7 and 14 have more binding energy with SARS-CoV-2 main protease recently crystallized (pdb code 6LU7) in comparison with the other imidazole derivatives and the two drug; Chloroquine and hydroxychloroquine. Because of the best energy of interaction, these three molecules could have the most potential antiviral treatment of COVID-19 than the other studied compounds. The structures with best affinity in the binding site of the protease have more than 3 cycles and electronegative atoms in the structure. This may increase the binding affinity of these molecules because of formation of p-bonds, halogen interactions and/or Hydrogen bond interactions between compounds and the enzyme. So, compounds with more cycles and electronegative atoms could have a potent inhibition of SARS-CoV-2 main protease.

New investigation of 1-substituted imidazole derivatives as thermal latent catalysts for epoxy-phenolic resins

Novel 1-substituted imidazole derivatives (4-10) were synthesized by imidazole and the corresponding substituted reagents (chloromethylpivalate, diphenylphosphinicchloride, di-tert-butyldicarbonate, 1,1′-oxalylchloride, pyrazine, phneylisocyanat, and p-toluensulfonylchloride). Polymerization of diglycidyl ether of bisphenol A (DGEBA) with 1-substituted imidazole derivatives, two commercial available catalysts (imidazole and 1-cyanoethyl-2-ethyl-4-methylimidazole) and N-benzylpyrazinium hexafluoroantimonate were investigated as model reactions of epoxy resin systems with respect to the thermal latency and storage stability of the catalysts. The catalytic activity of I-substituted imidazole derivatives 4-10 depended on the steric and withdrawing electronic effect of the substitution groups. To characterize the cure activation energy and the viscosity-storage time, the order of thermally latent activity is 1-tosylimidazole (6) > 1,1′-oxalyldiimidazole (8) > N-benzylpyrazinium hexafluoroantimonate (BPH, 3) > 1-tritylimidazole (9) > N-phenyl-imidazole-1-carboxamide (5) > 3-(diphenylphosphinoyl)imidazole (7) > tert-butyl-1H-imidazole-1-carboxylate (4) > 1-cyanoethyl-2-ethyl-4-methylimidazole (2E4MZ, 2) > 1-[(pivalyloxy)methyl]imidazol (10) > imidazole (1). In comparison with commercially available catalysts imidazole (1) and 1-cyanoethyl-2-ethyl-4-methylimidazole (2) and a cationic latent catalyst N-benzylpyrazinium hexafluoroantimonate (BPH, 3) as the standard compounds, in addition to 1-[(pivalyloxy)methyl]imidazole (10), the I-substituted imidazole derivatives (4-9) revealed better thermal latency.
