Grob, C. A. published the artcileThe nature of the inductive effect, Category: chlorides-buliding-blocks, the publication is Chemistry & Industry (London, United Kingdom) (1955), 1222-3, database is CAplus.

The acidity constants of the α-, β-, and γ-betaine hydrochlorides (ClMe₃N(CH₂)_nCO₂H, where n = 1, 2, and 3, resp.); of the 2-, 3-, and 4-carboxylic acids of N,N-dimethylpiperidinium chloride; and of the 2-, 3-, and 4-carboxylic acids of N-methylquinuclidinium chloride were measured. The magnitude of the acid-strengthening effect decreased proportionally to direct distance rather than to chain length. The so-called general inductive effect appears as a function of the direct distance between electrostatically interacting groups and the dielec. constant of the intervening medium, which can be a chain of atoms, solvent, or empty space, according to the geometry of the system.

Amata, Emanuele published the artcile(+)-Methyl (1R,2S)-2-{[4-(4-Chlorophenyl)-4-hydroxypiperidin-1-yl]methyl}-1-phenylcyclopropanecarboxylate [(+)-MR200] Derivatives as Potent and Selective Sigma Receptor Ligands: Stereochemistry and Pharmacological Properties, Recommanded Product: ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Journal of Medicinal Chemistry (2018), 61(1), 372-384, database is CAplus and MEDLINE.

Methoxycarbonyl-1-phenyl-2-cyclopropylmethyl based derivatives [cis-(+)-MR200], [cis-(-)-MR201], and [trans-(±)-MR204], have been identified as new potent sigma (σ) receptor ligands. In the present paper, novel enantiomerically pure analogs were synthesized and optimized for their σ receptor affinity and selectivity. Docking studies rationalized the results obtained in the radioligand binding assay. Absolute stereochem. was unequivocally established by X-ray anal. of a precursor as camphorsulfonyl derivative The most promising compound, I, showed remarkable selectivity over a panel of more than 15 receptors as well as good chem. and enzymic stability in human plasma. An in vivo evaluation evidenced that I, in contrast to its isomers, which behave as σ₁ antagonists, exhibited a σ₁ agonist profile. These data clearly demonstrated that compound I, due to its σ₁ agonist activity and favorable receptor selectivity and stability, provided an useful tool for the study of σ₁ receptors.

The importance of polymers in medicine and technol. requires need for a detailed study of the properties not only of the polymer itself but also its interaction with organic solvents, water, plasticizers and others. In most cases, these same fluids themselves are solvents for the polymer therefore this interaction should be considered as the basis for polymer processing solutions through films.

Zhang, Shuai-Bing published the artcileAntifungal mechanism of 1-nonanol against Aspergillus flavus growth revealed by metabolomic analyses, Product Details of C7H16ClNO2, the publication is Applied Microbiology and Biotechnology (2021), 105(20), 7871-7888, database is CAplus and MEDLINE.

Chem. control of fungal spoilage of postharvest cereal grains is an important strategy for the management of grain storage. Here, the potential antifungal activity of 1-nonanol, a main component of cereal volatiles, against Aspergillus flavus was studied. The growth of A. flavus was completely inhibited by 0.11 and 0.20 μL/mL 1-nonanol at vapor and liquid contact phases, resp. Metabolomic anal. identified 135 metabolites whose expression was significantly different between 1-nonanol-treated and untreated A. flavus. These metabolites were involved in the tricarboxylic acid cycle, amino acid biosynthesis, protein degradation and absorption, aminoacyl-tRNA biosynthesis, mineral absorption, and in interactions with ABC transporters. Biochem. validation confirmed the disruptive effect of 1-nonanol on A. flavus growth, as indicated by the leakage of intracellular electrolytes, decreased succinate dehydrogenase, mitochondrial dehydrogenase, and ATPase activity, and the accumulation of reactive oxygen species. We speculated that 1-nonanol could disrupt cell membrane integrity and mitochondrial function and might induce apoptosis of A. flavus mycelia. Simulated grain storage experiments showed that 1-nonanol vapor, at a concentration of 264 μL/L, completely inhibited A. flavus growth in wheat, corn, and paddy grain with an 18% moisture content. This study provides new insights into the antifungal mechanism of 1-nonanol against A. flavus, indicating that it has a promising potential as a bio-preservative to prevent fungal spoilage of postharvest grains. 1-Nonanol showed higher antifungal activity against A. flavus. · The antifungal mechanisms of 1-nonanol against A. flavus were revealed. · 1-Nonanol could damage cell membrane integrity and mitochondrial function.

Aryldiazonium salts were proved to initiate the regioselective cleavage of aziridines for the installation of varied functional groups to gave β-substituted aryl sulfonamides I [R¹ = Ph, 4-MeC₆H₄, 4-ClC₆H₄, etc.; R² = H, Me; R³ = OMe, OBn, SPh, etc.]. The ring-opening process was effective and general for a variety of nucleophiles, including [O], [S] and [N] at room temperature This highly regioselective process, which could be performed at the gram scale, enjoys operational simplicity, as well as mild and metal-free conditions. The postulated reaction mechanism involved a single electron transfer from aziridines to aryldiazonium salts, which generates a highly reactive amino radical cation.
