Schmiegel, Carsten J. published the artcileContinuous Flow Synthesis of Azoxybenzenes by Reductive Dimerization of Nitrosobenzenes with Gel-Bound Catalysts, Safety of 2-Aminobenzonitrile(Flakes or Chunks), the main research area is flow synthesis azoxybenzene reductive dimerization nitrosobenzene gel bound catalyst.

In the search for a new synthetic pathway for azoxybenzenes with different substitution patterns, an approach using a microfluidic reactor with gel-bound proline organocatalysts under continuous flow is presented. Herein the formation of differently substituted azoxybezenes by reductive dimerization of nitrosobenzenes within minutes at mild conditions in good to almost quant. yields is described. The conversion within the microfluidic reactor is analyzed and used for optimizing and validating different parameters. The effects of the different functionalities on conversion, yield, and reaction times are analyzed in detail by NMR. The applicability of this reductive dimerization is demonstrated for a wide range of differently substituted nitrosobenzenes. The effects of these different functionalities on the structure of the obtained azoxyarenes are analyzed in detail by NMR and single-crystal X-ray diffraction. Based on these results, the turnover number and the turnover frequency were determined

Kodama, Susumu published the artcileAssociation between in vitro nuclear receptor-activating profiles of chemical compounds and their in vivo hepatotoxicity in rats, Safety of Phthalonitrile, the main research area is chem compound nuclear receptor activating profile hepatotoxicity.

The liver plays critical roles to maintain homeostasis of living organisms and is also a major target organ of chem. toxicity. Meanwhile, nuclear receptors (NRs) are known to regulate major liver functions and also as a critical target for hepatotoxic compounds In this study, we established mammalian one-hybrid assay systems for five rat-derived NRs, namely PXR, PPARα, LXRα, FXR and RXRα, and evaluated a total of 326 compounds for their NR-activating profiles. Then, we assessed the association between their NR-activating profile and hepatotoxic endpoints in repeated-dose toxicity data of male rats from Hazard Evaluation Support System. In the in vitro cell-based assays, 68, 38, 20, 17 and 17 compounds were identified as positives for PXR, PPARα, LXRα, FXR and RXRα, resp. The association analyses demonstrated that the PXR-pos. compounds showed high frequency of endpoints related to liver hypertrophy, such as centrilobular hepatocellular hypertrophy, suggesting that PXR activation is involved in chem.-induced liver hypertrophy in rats. It is intriguing to note that the PXR-pos. compounds also showed statistically significant associations with both prolonged activated partial thromboplastin time and prolonged prothrombin time, suggesting a possible involvement of PXR in the regulation of blood clotting factors. Collectively, our approach may be useful for discovering new functions of NRs as well as understanding the complex mechanism for hepatotoxicity caused by chem. compounds

Palmeri, M. published the artcileDominant lactic acid bacteria in naturally fermented milks from Messinese goat’s breed, Synthetic Route of 100-70-9, the main research area is lactic acid bacteria fermented milk Messinese goat breed.

Background: Lactic Acid Bacteria (LAB) are an important group of microorganisms responsible for the fermentation dairy products. This study was done to identify the dominant lactic acid bacteria in naturally fermented milks from Messinese goat’s breed. Methods: Eighteen individual raw milk samples collected from Messinese goat’s breed were acidified at pH 5.20 and left to spontaneously ferment at 37°C for 4 days. All samples were analyzed for rod- and coccus-shaped LAB. Also, all presumptive LAB were isolated and differentiated according to their phenotypic properties and genetic polymorphisms and then identified by sequencing the 16S rRNA gene. Data were statistically analyzed using SAS 9.2 software. Results: Levels of coccus- and rod-shaped LAB were in the range of 1.78-7.10 log and 1.00-7.09 log colony forming unit/mL, resp. The microbiol. counts on the two different growth media were significantly (p<0.05) different among the samples. Among 12 identified strains, the most numerous one was Enterococcus hirae (n = 4), followed by E. faecium (n = 3), while the other species (E. durans, E. faecalis, E. lactis, Lactococcus lactis, and Leuconostoc lactis) included one strain each. Conclusion: The major group identified in this study was mainly represented by members of Enterococcus genus. Although Enterococcus spp. are related to the typicality of some traditional fermented dairy products, this study highlights the need for risk assessment of pathogenic enterococci species for the consumers.

Potikha, L. M. published the artcileRearrangement of benzyl derivatives of condensed 3-aminoisoquinolinones, Quality Control of 73217-11-5, the main research area is benzophenathridine preparation; isoquinoIinenone isoquinazolinone phenylacetonitrile rearrangement.

A new method for contructing the benzo[b]phenathridine system is proposed. Melting of benzimidazo[1,2-b]isoquinoline-11(5H)-one or 5,13-dihydro-11H-isoquino[3,2-b]quinazolin-11-one with [2-(bromomethyl)phenyl]acetonitrile leads to the formation of C-benzylation products, which is accompanied by intramol. acylation over the β-Carbon of the enamine fragment of the mols. Heating the fusion product in the presence of an acid provokes splitting of the isoquinoline ring and rearrangement to the 12,12a-dihydrobenzo[b]phenanthridine-5(6H)-one derivatives The features of the spatial structure of reaction products and their chem. behavior are considered.

Wollenweber, Eckhard published the artcile8,2′-Dihydroxyflavone from Primula pulverulenta, Name: 2,3-Dimethoxybenzonitrile, the main research area is hydroxyflavone Primula.

A novel flavone, isolated from the farinose exudate of P. pulverulenta, was identified as 8,2′-dihydroxyflavone (I). This is the first naturally occurring flavone in which ring A is oxygenated only at C-8. The structure was deduced from spectral comparisons with the structurally related flavones 5,2′-, 3,2′-, and 2′,3′-dihydroxyflavone and confirmed by total synthesis. The spectral properties of other flavones oxygenation with a simple pattern are discussed in relation to 8,2′-dihydroxyflavone.

Sai Kumar, Gobbilla published the artcileHydroboration of nitriles, esters, and amides catalyzed by simple neosilyllithium, Name: Picolinonitrile, the main research area is hydroboration nitrile ester amide preparation aralkyl amine alc; lithium organometallic catalyst hydroboration reduction nitrile ester amide; crystal mol optimized structure picolyl diborylamine.

We present here an efficient method for the hydroboration of organic nitriles, carboxylic esters, and carboxamides with pinacolborane (HBpin) using an alkali metal catalyst, neosilyllithium (LiCH2SiMe3), in neat reaction conditions. The reactions were accomplished with efficient catalytic reactivity and demonstrated by neosilyllithium at room temperature, in solvent-free condition, to afford a high yield of the corresponding N-boryl amines, boryl ethers, and amine hydrochlorides. The protocol for the catalytic reaction presented in this paper is simple and efficient, with diverse substrate scope for nitriles, carboxylic esters, and carboxamides showing excellent functional group tolerance. DLPNO-CCSD(T) calculations were also performed, showing that the hydroboration of nitriles catalyzed by neosilyllithium occurs through the pre-coordination of the nitrile at Lewis acid lithium followed by hydride migration from the B-H entity.

Malviya, Novina published the artcileAmino-Acid-Derived Emerging Sensor for Detection of S 2 Ion and MeOH Percentage in MeOH-H2O Mixture, Application In Synthesis of 1885-29-6, the main research area is aminoacid emerging sensor detection mixture.

Designing fluorescent probes and its metal-organic materials getting attention due to their fascinating utility in several fields from material to biol. Here, we synthesized N-Ph glycine substituted four new fluorescent probes viz. (2-cyanophenyl)glycine [HL1], (5-chloro-2-cyanophenyl)glycine [HL2], (4-chloro-2-cyanophenyl)glycine [HL3], (2-cyano-3-fluorophenyl)glycine [HL4] and investigated its properties through spectroscopic techniques. Out of all probes, HL1 displayed non-emissive nature in the presence of water and uniquely detect the percentage of methanol in the methanol-water mixture or vice-versa out of the different solvent-water mixture with the help of fluorometric technique. Furthermore, cobalt complex [Co(L1)(phen)2]ClO4 (C1) with distorted octahedral geometry has been synthesized by using HL1. The emissive nature of the complex C1 was further utilized for the selective sensing of S2- ion in the DMSO-water mixture by quenching the fluorescence with a detection limit of 4.8 μM. The selective solvent percentage detection and anion sensing illustrate the potential efficacy of the designed sensors for anal. intent.
