S.; Shashikanth, J.; Nizam, Aatika; Nagaraju, G.. Electric Literature of C7H4BrNThis research focused onzirconium phosphate nanoparticle photocatalytic degradation. The article conveys some information:

Water pollution has increased swiftly, especially the dyes from industries that have disturbed aquatic eco-system. Photocatalytic degradation (PCD) is one of the attractive methods to eliminate dyes from industrial effluents. Zirconium phosphate (ZP) nanoparticles were synthesized by combustion method using zirconyl nitrate and phosphorous pentoxide as precursors. The obtained ZP was characterized by powder X-ray diffractogram, Fourier transform IR, SEM, high-resolution transmission electron microscopy, Raman spectroscopy, photoluminescence spectroscopy, Brunauer-Emmett-Teller surface area. PCD was carried out using methylene blue as a model pollutant in aqueous medium in the presence of UV light irradiation with different concentrations of dye, catalyst and pH. Higher degradation efficiency was observed in basic medium. ZP is employed as a catalyst to form nitrides from aldehydes using different solvents with different aldehydes.

《A New Class of Dengue and West Nile Virus Protease Inhibitors with Submicromolar Activity in Reporter Gene DENV-2 Protease and Viral Replication Assays》 was published in Journal of Medicinal Chemistry in 2020. These research results belong to Kuehl, Nikos; Graf, Dominik; Bock, Josephine; Behnam, Mira A. M.; Leuthold, Mila-Mareen; Klein, Christian D.. Name: 4-Cyanobenzyl bromide The article mentions the following:

Dengue and West Nile virus are rapidly spreading global pathogens for which no specific therapeutic treatments are available. One of the promising targets for drug discovery against dengue and other flaviviruses is the viral serine protease NS2B-NS3. We present the design, synthesis, and in vitro and cellular characterization of a novel chemotype of potent small-mol. non-peptidic dengue protease inhibitors derived from 4-benzyloxyphenylglycine. A newly developed luciferase-based DENV-2 protease reporter system in HeLa cells (DENV2proHeLa) was employed to determine the activity of the compounds in a cellular environment. Specificity and selectivity of the DENV2proHeLa system were confirmed by viral titer reduction assays. The compounds reach low micromolar to upper nanomolar inhibitory potency in cell-based assays, are selective against other serine proteases, and do not show relevant cytotoxicity. An extensive structure-activity relationship study provides a perspective for further drug development against flaviviral infections. In the experiment, the researchers used many compounds, for example, 4-Cyanobenzyl bromide(cas: 17201-43-3Name: 4-Cyanobenzyl bromide)

4-Cyanobenzyl bromide(cas: 17201-43-3) is a white solid. Its melting point is 113-117°C, and flash point is 125.1°C. It is insoluble in water at 20°C. It is stable under normal temperatures and pressures. It should be stored at 0-5°C.Name: 4-Cyanobenzyl bromide
