The article was appeared in 《Archiv der Pharmazie (Weinheim, Germany)》. They have made some progress in their research.Reference of 3-Cyanopyridine The article mentions the following:

A new class of cyanopyridine derivatives containing the phenylurea unit was synthesized and tested against some metabolic enzymes including acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and α-glycosidase (α-Gly). The new cyanopyridine derivatives showed Ki values in the range of 40.73 ± 6.54 to 87.05 ± 16.98μM against AChE, 29.17 ± 4.88 to 124.03 ± 22.43μM against BChE, and 3.66 ± 0.93 to 26.33 ± 5.05μM against α-Gly. These inhibition effects were compared with standard enzyme inhibitors like tacrine (for AChE and BChE) and acarbose (for α-Gly). Also, these cyanopyridine derivatives with the best inhibition score were docked into the active site of the indicated metabolic enzymes. Finally, mol. docking calculations were made to compare the biol. activities of the compounds against AChE (-8.81 kcal/mol for mol. 11d, I), BChE (-3.52 kcal/mol for mol. 11d), and α-Gly (-2.98 kcal/mol for mol. 11a, II). After mol. docking calculations, the ADME/T anal. was performed to examine the future drug use properties of the new cyanopyridine derivatives containing phenylurea. And 3-Cyanopyridine (cas: 100-54-9) was used in the research process.

The article contains the following contents:

Conventional synthetic methods to yield polycyclic heteroarenes have largely relied on metal-mediated arylation reactions requiring pre-functionalised substrates. However, the functionalization of unactivated azines has been restricted because of their intrinsic low reactivity. Herein, a transition-metal-free, radical relay π-extension approach to produce N-doped polycyclic aromatic compounds directly from simple azines and cyclic iodonium salts is reported. Mechanistic and ESR studies provide evidence for the in situ generation of organic electron donors, while chem. trapping and electrochem. experiments implicate an iodanyl radical intermediate serving as a formal biaryl radical equivalent This intermediate, formed by one-electron reduction of the cyclic iodonium salt, acts as the key intermediate driving the Minisci-type arylation reaction. The synthetic utility of this radical-based annulative π-extension method is highlighted by the preparation of an N-doped heptacyclic nanographene fragment through fourfold C-H arylation.3-Cyanopyridine (cas: 100-54-9) were involved in the experimental procedure.

The article contains the following contents:

For medicines, the apparent membrane permeability coefficients (Papp) across human colorectal carcinoma cell line (Caco-2) monolayers under a pH gradient generally correlate with the fraction absorbed after oral intake. Furthermore, the in vitro Papp values of 29 industrial chems. were found to have an inverse association with their reported no-observed effect levels for hepatotoxicity in rats. In the current study, we expanded our influx permeability predictions for the 90 previously investigated chems. to both influx and efflux permeability predictions for 207 diverse primary compounds, along with those for 23 secondary compounds Trivariate linear regression anal. found that the observed influx and efflux logPapp values determined by in vitro experiments significantly correlated with mol. weights and the octanol-water distribution coefficients at apical and basal pH levels (pH 6.0 and 7.4, resp.) (apical to basal, r = 0.76, n = 198; and basal to apical, r = 0.77, n = 202); the distribution coefficients were estimated in silico. Further, prediction accuracy was enhanced by applying a light gradient boosting machine learning system (LightGBM) to estimate influx and efflux logPapp values that incorporated 17 and 19 in silico chem. descriptors (r = 0.83-0.84, p < 0.001). The determination in vitro and/or prediction in silico of permeability coefficients across intestinal cell monolayers of a diverse range of industrial chems./food components/medicines could contribute to the safety evaluations of oral intakes of general chems. in humans. Such new alternative methods could also reduce the need for animal testing during toxicity assessment.3-Cyanopyridine (cas: 100-54-9) were involved in the experimental procedure.

The article contains the following contents:

The hydrogen-bond-accepting abilities for more than 100 organic mols. are quantified using 19F and 31P NMR spectroscopy with pentafluorobenzoic acid (PFBA) and phenylphosphinic acid (PPA) as com. available, inexpensive probes. Anal. of pyridines and anilines with a variety of electronic modifications demonstrates that changes in NMR shifts can predict the secondary effects that contribute to H-bond-accepting ability, establishing the ability of PFBA and PPA binding to predict electronic trends. The H-bond-accepting abilities of various metal-chelating ligands and organocatalysts are also quantified. The measured Δδ(31P) and Δδp(19F) values correlate strongly with Hammett parameters, pKa of the protonated HBA, and proton-transfer basicity (pKBH+).

Lanthanide Coordination Polymer-Based Composite Films for Selective and Highly Sensitive Detection of Cr2O72- in Aqueous Media

Due to the high carcinogenicity and bioaccumulation effects of dichromate ions in the human body, sensitive and rapid detection of Cr2O72- ions is necessary. Herein, two lanthanide coordination polymers based on a linear dicarboxylic acid ligand, named {Ln(cpon)(Hcpon)(H2O)(3)}(n) [Ln = Tb, Tbcpon; Eu, Eucpon; H-2 cpon = 5-(4-carboxy-phenoxy)-nicotinic acid], have been successfully synthesized. These two isostructural compounds contain one-dimensional zigzag chains that consist of uncoordinated carboxyl groups and pyridine groups in the framework, and the one-dimensional chains can further form a three-dimensional supramolecular stacking structure by intermolecular interaction. Both Tbcpon and Eucpon show good luminescence performance and high stability. Tbcpon exhibits a good ability to sense Cr2O72- ions in aqueous solution. Moreover, the composite film material composed of Tbcpon and poly(methyl methacrylate) (PMMA) exhibits superior luminescence properties compared to those of pure Tbcpon. The Tbcpon-PMMA film exhibits an excellent ability to recognize Cr2O72- ions with high selectivity and a low detection limit of 5.6 ppb, which the maximum contamination standard of 100 ppb in drinking water specified by the U.S. Environmental is much lower than Protection Agency. Furthermore, the Tbcpon-PMMA film shows good recyclability for more than five cycles and anti-interference ability. After the introduction of the slightly soluble polymer poly(vinyl alcohol) (PVA), the Tbcpon-PVA composite film can effectively detect Cr2O72- ions in as little as 1 min. These composite films could be potentially used as test strips for trace detection and rapid detection of Cr2O72- ions in aqueous solution.

Theoretical study of chloride complexes with hybrid macrocycles

Anions show relevant roles in biological routes. The supramolecular chemistry investigates the chemical bonding between two or more molecules and/or ions. Herein, the nature of the bond between chloride anions and macrocycle receptors elaborated from (i) pyridines, (ii) pyrroles, (iii) borazines, (iv) triazines, and (v) 1,2,3-triazole rings are studied. The energy decomposition analysis (EDA) shows that the receptors that predominantly establish non-covalent interactions with the Cl- anions proportionate a preferable bond than the macrocycles that mostly form a covalent interaction with the Cl- anions. The substitution of pyridine by borazine rings in the macrocycles or the protonation of the receptors increases the interaction with the Cl- anions since there is an increase in the number of -BH or -NH groups available to establish hydrogen bonds with the Cl- anions. In addition, the pyridine -> borazine substitution decreases the number of repulsive interactions. The substitution of pyrrole by 1,2,3-triazole rings does not relevantly favor the interaction with the Cl- anions. The substitution of pyridine by the triazine rings or the addition of electron-withdrawing groups (-OH, -F and -NO2) in the receptor structures increases the acidity of the cavity of the macrocycles and, therefore, favors the interaction with the Cl- anions. The addition of electron-donating groups (-NH2) to the receptor structure promotes the opposite effect. Accordingly, the present investigation brings relevant information for the design of new hybrid macrocycles with the potential for anionic recognition.
