《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)

In 2022,Nguyen, Thuy; Gamage, Thomas F.; Finlay, David B.; Decker, Ann M.; Langston, Tiffany L.; Barrus, Daniel; Glass, Michelle; Li, Jun-Xu; Kenakin, Terry P.; Zhang, Yanan published an article in Journal of Medicinal Chemistry. The title of the article was 《Development of 3-(4-Chlorophenyl)-1-(phenethyl)urea Analogues as Allosteric Modulators of the Cannabinoid Type-1 Receptor: RTICBM-189 is Brain Penetrant and Attenuates Reinstatement of Cocaine-Seeking Behavior》.Formula: C8H6BrN The author mentioned the following in the article:

We have shown that CB1 receptor neg. allosteric modulators (NAMs) attenuated the reinstatement of cocaine-seeking behaviors in rats. In an effort to further define the structure-activity relationships and assess the druglike properties of the 3-(4-chlorophenyl)-1-(phenethyl)urea-based CB1 NAMs that we recently reported, we introduced substituents of different electronic properties and sizes to the phenethyl group and evaluated their potency in CB1 calcium mobilization, cAMP, and GTPγS assays. We found that 3-position substitutions such as Cl, F, and Me afforded enhanced CB1 potency, whereas 4-position analogs were generally less potent. The 3-chloro analog (31, RTICBM-189)(I) showed no activity at >50 protein targets and excellent brain permeation but relatively low metabolic stability in rat liver microsomes. Pharmacokinetic studies in rats confirmed the excellent brain exposure of 31 with a brain/plasma ratio Kp of 2.0. Importantly, i.p. administration of 31 significantly and selectively attenuated the reinstatement of the cocaine-seeking behavior in rats without affecting locomotion. In addition to this study using 2-(3-Bromophenyl)acetonitrile, there are many other studies that have used 2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5Formula: C8H6BrN) was used in this study.
