Aretz, Christopher D.; Kharade, Sujay V.; Chronister, Keagan; Rusconi Trigueros, Renata; Martinez Rodriguez, Erick J.; Piermarini, Peter M.; Denton, Jerod S.; Hopkins, Corey R. published an article in 2021. The article was titled 《Further SAR on the (Phenylsulfonyl)piperazine Scaffold as Inhibitors of the Aedes aegypti Kir1 (AeKir) Channel and Larvicides》, and you may find the article in ChemMedChem.Synthetic Route of C7H3BrFN The information in the text is summarized as follows:

Zika virus (ZIKV), dengue fever (DENV) and chikungunya (CHIKV) are arboviruses that are spread to humans from the bite of an infected adult female Aedes aegypti mosquito. As there are no effective vaccines or therapeutics for these diseases, the primary strategy for controlling the spread of these viruses is to prevent the mosquito from biting humans through the use of insecticides. Unfortunately, the commonly used classes of insecticides have seen a significant increase in resistance, thus complicating control efforts. Inhibiting the renal inward rectifier potassium (Kir) channel of the mosquito vector Aedes aegypti has been shown to be a promising target for the development of novel mosquitocides. We have shown that Kir1 channels play key roles in mosquito diuresis, hemolymph potassium homeostasis, flight, and reproduction Previous work from our laboratories identified a novel (phenylsulfonyl)piperazine scaffold as potent AeKir channel inhibitors with activity against both adult and larval mosquitoes. Herein, we report further the synthesis and SAR work around this scaffold and have identified addnl. compounds, e.g., I and II, with improved in vitro potency and mosquito larvae toxicity. In addition to this study using 4-Bromo-2-fluorobenzonitrile, there are many other studies that have used 4-Bromo-2-fluorobenzonitrile(cas: 105942-08-3Synthetic Route of C7H3BrFN) was used in this study.

An expansive data set containing 33 substrates, 36 unique monophosphine ligands, and two solvents was produced for the NiCl2·6H2O catalyzed aryl (pseudo)halide borylation with tetrahydroxydiboron for a total of 1632 reactions. Exploratory data anal. revealed excellent reaction performance with simple triarylphosphines (P(p-F-Ph)3 and P(p-Anis)3) and mixed aryl-alkyl phosphines (PPh2Cy), in addition to the previously established high performance with Cy-JohnPhos. The data were used to train machine learning models that predicted out of sample reaction performance with a root-mean-square error of 18.4. The important features extracted from the models identified three phosphine parameters that offered reliable reactivity thresholds for identifying optimal ligand performance. The predictive models showed reasonable performance for predicting reaction yields employing ligands not included in model training, while the important feature boundaries accurately classified the performance of 10 of the 12 external ligands examined4-Bromo-2-fluorobenzonitrile(cas: 105942-08-3Application of 105942-08-3) was used in this study.

COA of Formula: C8H6BrNIn 2019 ,《Synthesis of N-benzyl substituted 1,4-imino-L-lyxitols with a basic functional group as selective inhibitors of Golgi α-mannosidase IIb》 appeared in Bioorganic Chemistry. The author of the article were Klunda, Tomas; Sestak, Sergej; Kona, Juraj; Polakova, Monika. The article conveys some information:

Inhibition of the biosynthesis of complex N-glycans in the Golgi apparatus is one of alternative ways to suppress growth of tumor tissue. Eight N-benzyl substituted 1,4-imino-L-lyxitols with basic functional groups (amine, amidine, guanidine), hydroxyl and fluoro groups were prepared, optimized their syntheses and tested for their ability to inhibit several α-mannosides from the GH family 38 (GMIIb, LManII and JBMan) as models for human Golgi and lysosomal α-mannoside II. All compounds were found to be selective inhibitors of GMIIb. The most potent structure bearing guanidine group, inhibited GMIIb at the micromolar level (Ki = 19 ± 2 μM) while no significant inhibition (>2 mM) of LManII and JBMan was observed Based on mol. docking and pKa calculations this structure may form two salt bridges with aspartate dyad of the target enzyme improving its inhibitory potency compared with other N-benzyl substituted derivatives published in this and previous studies. The results came from multiple reactions, including the reaction of 4-Cyanobenzyl bromide(cas: 17201-43-3COA of Formula: C8H6BrN)

4-Cyanobenzyl bromide(cas: 17201-43-3) can reacts with 2H-tetrazole in the presence of KOH to yield 4-[(2H-tetra-zol-2-yl)methyl]benzonitrile. And it may be used in the synthesis of ligands containing a chelating pyrazolyl-pyridine group with a pendant aromatic nitrile.COA of Formula: C8H6BrN
