Product Details of 105942-08-3. The article was titled 《Improving the Selectivity of PACE4 Inhibitors through Modifications of the P1 Residue》. The information in the text is summarized as follows:

Paired basic amino acid cleaving enzyme 4 (PACE4), a serine endoprotease of the proprotein convertases family, has been recognized as a promising target for prostate cancer. We previously reported a selective and potent peptide-based inhibitor for PACE4, named the multi-Leu peptide (Ac-LLLLRVKR-NH2 sequence), which was then modified into a more potent and stable compound named C23 with the following structure: Ac-DLeu-LLLRVK-Amba (Amba: 4-amidinobenzylamide). Despite improvements in both in vitro and in vivo profiles of C23, its selectivity for PACE4 over furin was significantly reduced. We examined other Arg-mimetics instead of Amba to regain the lost selectivity. Our results indicated that the replacement of Amba with 5-(aminomethyl)picolinimidamide increased affinity for PACE4 and restored selectivity. Our results also provide a better insight on how structural differences between S1 pockets of PACE4 and furin could be employed in the rational design of selective inhibitors. In the experiment, the researchers used many compounds, for example, 4-Bromo-2-fluorobenzonitrile(cas: 105942-08-3Product Details of 105942-08-3)

In 2019,Asian Journal of Organic Chemistry included an article by Kim, Jihyeon; Golime, Gangadhararao; Kim, Hun Young; Oh, Kyungsoo. Safety of 4-Fluorobenzonitrile. The article was titled 《Copper(II)-Catalyzed Aerobic Oxidation of Amines: Divergent Reaction Pathways by Solvent Control to Imines and Nitriles》. The information in the text is summarized as follows:

The Cu(OAc)2-catalyzed aerobic oxidations of amines to imines RR1CH=NR2 [R = H, Me; R1 = Ph, 4-MeC6H4, 2-thienyl, etc.; R2 = cyclohexyl, Ph, Bn, etc.] and nitriles R3CN [R3 = n-heptyl, Ph, 2-thienyl, etc.] were identified under solvent control conditions and in the presence of mol. oxygen. By modulating the aerobic oxidation pathways of Cu(OAc)2 catalyst in different reaction solvents, the selective formations of homo-coupled imines, cross-coupled imines and nitriles were achieved from amine derivatives In the experiment, the researchers used 4-Fluorobenzonitrile(cas: 1194-02-1Safety of 4-Fluorobenzonitrile)

In 2019,Journal of Medicinal Chemistry included an article by Pirzer, Anna S.; Lasch, Roman; Friedrich, Heike; Huebner, Harald; Gmeiner, Peter; Heinrich, Markus R.. COA of Formula: C8H6BrN. The article was titled 《Benzyl Phenylsemicarbazides: A Chemistry-Driven Approach Leading to G Protein-Biased Dopamine D4 Receptor Agonists with High Subtype Selectivity》. The information in the text is summarized as follows:

Many subtype-selective dopamine receptor ligands developed for the D2-D4 family incorporate a 1-arylpiperazine-derived primary recognition motif, which is connected to a lipophilic moiety occupying an extended binding pocket (EBP) of the receptor via an aliphatic linker of variable lengths. The evaluation of a novel group of dopamine receptor ligands now showed that highly subtype-selective ligands [up to Ki(D4.4) = 0.25 nM, D2L/D4.4 = 320, D3/D4.4 = 710 for APH199 (17)] can be obtained by choosing a relatively large and conformationally flexible 1-benzyl-1-phenylsemicarbazide substructure to fill the EBP. The novel chemotype APH199 (17) was found to act as a full agonist at the D4 receptor showing significant bias toward G protein activation over β-arrestin recruitment in comparison to quinpirole. In the experiment, the researchers used many compounds, for example, 4-Cyanobenzyl bromide(cas: 17201-43-3COA of Formula: C8H6BrN)

In 2019,ACS Medicinal Chemistry Letters included an article by Hu, Xianglong; Wan, Baojie; Liu, Yang; Shen, Jiayi; Franzblau, Scott G.; Zhang, Tianyu; Ding, Ke; Lu, Xiaoyun. Quality Control of 4-Bromo-2-fluorobenzonitrile. The article was titled 《Identification of Pyrazolo[1,5-a]pyridine-3-carboxamide Diaryl Derivatives as Drug Resistant Antituberculosis Agents》. The information in the text is summarized as follows:

A series of pyrazolo[1,5-a]pyridine-3-carboxamide (PPA) derivatives bearing diaryl side chain was designed and synthesized as new antituberculosis agents, aiming to improve the efficacy toward drug resistant Mycobacterium tuberculosis (Mtb) strains. Most of the substituted di-Ph and heterodiaryl PPAs exhibited excellent in vitro potency against the drug susceptive H37Rv strain (MIC < 0.002-0.381 μg/mL) and drug resistant Mtb strains (INH-resistant (rINH), MIC < 0.002-0.465 μg/mL; RMP-resistant (rRMP), MIC < 0.002-0.004 μg/mL). Noticeably, some compounds also showed very low cytotoxicity against Vero cells. Further, compound I displayed good pharmacokinetic profiles with oral bioavailability (F) of 41% and significantly reduced the bacterial burden in an autoluminescent H37Ra infected mouse model.

The author of 《An Experimental Acidity Scale for Intramolecularly Stabilized Silyl Lewis Acids》 were Kuenzler, Sandra; Rathjen, Saskia; Merk, Anastasia; Schmidtmann, Marc; Mueller, Thomas. And the article was published in Chemistry – A European Journal in 2019. HPLC of Formula: 1194-02-1 The author mentioned the following in the article:

A new NMR-based Lewis acidity scale is suggested and its application is demonstrated for a family of silyl Lewis acids. The reaction of p-fluorobenzonitrile (FBN) with silyl cations that are internally stabilized by interaction with a remote chalcogenyl or halogen donor yields silylated nitrilium ions with the silicon atom in a trigonal bipyramidal coordination environment. The 19F NMR chem. shifts and the 1J(CF) coupling constants of these nitrilium ions vary in a predictable manner with the donor capability of the stabilizing group. The spectroscopic parameters are suitable probes for scaling the acidity of Lewis acids. These new probes allow for the discrimination between very similar Lewis acids, which is not possible with conventional NMR tests, such as the well-established Gutmann-Beckett method. In the experiment, the researchers used 4-Fluorobenzonitrile(cas: 1194-02-1HPLC of Formula: 1194-02-1)
