Malecka, Magdalena;Machura, Barbara;Szlapa-Kula, Agata research published 《 Optical properties of 2,6-di(pyrazin-2-yl)pyridines substituted with extended aryl groups》, the research content is summarized as follows. A convenient one-pot method based on Krohnke condensation was used to obtain a series of new 2,6-di(pyrazin-2-yl)pyridines (dppy) functionalized with polyaromatic Ar groups: 1-naphthyl, 2-naphthyl, 9-anthryl, 9-phenanthryl, 1-pyrenyl and 2-triphenylenyl. From a structural point of view, the designed Ar-dppys are regarded as analogs of 2,2′:6′,2”-terpyridines, which are the most extensively used organic building blocks for supramol. and coordination chem. The main emphasis of the current research was put on systematic studies of the impact of the extended aryl group on electrochem., thermal and photophys. properties of Ar-dppys. The pendant aryl units in the studied Ar-dppys differ in the π-conjugation length, torsional hindrance due to the inter-ring H···H repulsions and abilities for donation of electron d. into π-conjugated trisheterocyclic unit (dppy). To get a deeper and wider understanding structure-property relationships, all presented Ar-dppys were also compared with previously reported aryl-substituted 2,2′:6′,2”-terpyridines (Ar-terpys). Addnl., the impact of solvent polarity on optical behavior of Ar-dppys was studied.

Series of Re(I) carbonyls complexes were designed and synthesized to explore the impact of the triimine skeleton and number of methoxy groups attached to aryl substituents on their optoelectronic and thermal properties. The chem. structures of the prepared complexes were confirmed by ¹H and ¹³C NMR spectroscopy, HR-MS, elemental anal., and x-ray measurements. DSC measurements showed that they melted in the range of 198-325°. Some of them form stable mol. glasses with high glass transition temperatures (158-173°). Exptl. obtained optical properties were supported by DFT calculations The UV-Vis spectra display a series of overlapping absorption bands in the range 200-350 nm, and much weaker broad band in the visible spectral region, due to intraligand and charge transfer transitions, resp. All synthesized complexes were emissive in solution and in solid state as powder. Moreover, when applied in diodes, some of them exhibited ability for emission of light under external voltage with maximum of electroluminescence band located at 591-630 nm.

Marcinek, Patrick;Haag, Franziska;Geithe, Christiane;Krautwurst, Dietmar research published 《 An evolutionary conserved olfactory receptor for foodborne and semiochemical alkylpyrazines》, the research content is summarized as follows. Mol. recognition is a fundamental principle in biol. systems. The olfactory detection of both food and predators via ecol. relevant odorant cues are abilities of eminent evolutionary significance for many species. Pyrazines are such volatile cues, some of which act as both human-centered key food odorants (KFOs) and semiochems. A pyrazine-selective odorant receptor has been elusive. Here we screened 2,3,5-trimethylpyrazine, a KFO and semiochem., and 2,5-dihydro-2,4,5-trimethylthiazoline, an innate fear-associated non-KFO, against 616 human odorant receptor variants, in a cell-based luminescence assay. OR5K1 emerged as sole responding receptor. Tested against a comprehensive collection of 178 KFOs, we newly identified 18 pyrazines and (2R/2S)-4-methoxy-2,5-dimethylfuran-3(2H)-one as agonists. Notably, OR5K1 orthologs in mouse and domesticated species displayed a human-like, potency-ranked activation pattern of pyrazines, suggesting a domestication-led co-evolution of OR5K1 and its orthologs. In summary, OR5K1 is a specialized olfactory receptor across mammals for the detection of pyrazine-based key food odors and semiochems.

Morris, Anna M.;Leonard, Stephen S.;Fowles, Jefferson R.;Boots, Theresa E.;Mnatsakanova, Anna;Attfield, Kathleen R. research published 《 Effects of E-Cigarette Flavoring Chemicals on Human Macrophages and Bronchial Epithelial Cells》, the research content is summarized as follows. E-cigarettes utilize a wide range of flavoring chems. with respiratory health effects that are not well understood. In this study, we used pulmonary-associated cell lines to assess the in vitro cytotoxic effects of 30 flavoring chems. Human bronchial epithelial cells (BEAS-2B) and both naive and activated macrophages (THP-1) were treated with 10, 100, and 1000μM of flavoring chems. and analyzed for changes in viability, cell membrane damage, reactive oxygen species (ROS) production, and inflammatory cytokine release. Viability was unaffected for all chems. at the 10 and 100μM concentrations At 1000μM, the greatest reductions in viability were seen with decanal, hexanal, nonanal, cinnamaldehyde, eugenol, vanillin, alpha-pinene, and limonene. High amounts of ROS were elicited by vanillin, ethyl maltol, and the diketones (2,3-pentanedione, 2,3-heptanedione, and 2,3-hexanedione) from both cell lines. Naive THP-1 cells produced significantly elevated levels of IL-1β, IL-8, and TNF-α when exposed to ethyl maltol and hexanal. Activated THP-1 cells released increased IL-1β and TNF-α when exposed to ethyl maltol, but many flavoring chems. had an apparent suppressive effect on inflammatory cytokines released by activated macrophages, some with varying degrees of accompanying cytotoxicity. The diketones, L-carvone, and linalool suppressed cytokine release in the absence of cytotoxicity. These findings provide insight into lung cell cytotoxicity and inflammatory cytokine release in response to flavorings commonly used in e-cigarettes.

Nicastri, Michael C.;Lehnherr, Dan;Lam, Yu-hong;DiRocco, Daniel A.;Rovis, Tomislav research published 《 Synthesis of Sterically Hindered Primary Amines by Concurrent Tandem Photoredox Catalysis》, the research content is summarized as follows. Primary amines are an important structural motif in active pharmaceutical ingredients (APIs) and intermediates thereof, as well as members of ligand libraries for either biol. or catalytic applications. Many chem. methodologies exist for amine synthesis, but the direct synthesis of primary amines with a fully substituted α carbon center is an underdeveloped area. We report a method which utilizes photoredox catalysis to couple readily available O-benzoyl oximes with cyanoarenes to synthesize primary amines with fully substituted α-carbons. We also demonstrate that this method enables the synthesis of amines with α-trifluoromethyl functionality. Based on exptl. and computational results, we propose a mechanism where the photocatalyst engages in concurrent tandem catalysis by reacting with the oxime as a triplet sensitizer in the first catalytic cycle and a reductant toward the cyanoarene in the second catalytic cycle to achieve the synthesis of hindered primary amines via heterocoupling of radicals from readily available oximes.

Omaiye, Esther E.;Luo, Wentai;McWhirter, Kevin J.;Pankow, James F.;Talbot, Prue research published 《 Electronic Cigarette Refill Fluids Sold Worldwide: Flavor Chemical Composition, Toxicity, and Hazard Analysis》, the research content is summarized as follows. Flavor chems. in electronic cigarette (EC) fluids, which may neg. impact human health, have been studied in a limited number of countries/locations. To gain an understanding of how the composition and concentrations of flavor chems. in ECs are influenced by product sale location, we evaluated refill fluids manufactured by one company (Ritchy LTD) and purchased worldwide. Flavor chems. were identified and quantified using gas chromatog./mass spectrometry (GC/MS). We then screened the fluids for their effects on cytotoxicity (MTT assay) and proliferation (live-cell imaging) and tested authentic standards of specific flavor chems. to identify those that were cytotoxic at concentrations found in refill fluids. A total of 126 flavor chems. were detected in 103 bottles of refill fluid, and their number per/bottle ranged from 1-50 based on our target list. Two products had none of the flavor chems. on our target list, nor did they have any nontargeted flavor chems. A total of 28 flavor chems. were present at concentrations ≥1 mg/mL in at least one product, and 6 of these were present at concentrations ≥10 mg/mL. The total flavor chem. concentration was ≥1 mg/mL in 70% of the refill fluids and ≥10 mg/mL in 26%. For sub-brand duplicate bottles purchased in different countries, flavor chem. concentrations were similar and induced similar responses in the in vitro assays (cytotoxicity and cell growth inhibition). The levels of furaneol, benzyl alc., ethyl maltol, Et vanillin, corylone, and vanillin were significantly correlated with cytotoxicity. The margin of exposure calculations showed that pulegone and estragole levels were high enough in some products to present a nontrivial calculated risk for cancer. Flavor chem. concentrations in refill fluids often exceeded concentrations permitted in other consumer products. These data support the regulation of flavor chems. in EC products to reduce their potential for producing both cancer and noncancer toxicol. effects.

The representativeness of the so-called biomimetic “in-bean” technique was studied by following the formation of target aroma compounds during the roasting course (10 points from 0 to 400 s) in recombined coffee beans and non-treated green coffee reference beans. For this purpose, the water-soluble fraction was replaced by a biomimetic recombinate in reconstituted beans prior to roasting. The targeted anal. of key aroma compounds was performed by means of the stable isotope dilution assay and solid-phase microextraction-gas chromatog.-mass spectrometry of roasted and ground coffee samples. The results were compared to the quant. data on a green coffee reference roasted under the same conditions. The results showed similar formation kinetics for most of the evaluated volatiles, such as Strecker aldehydes, alkylpyrazines, or α-diketones. In addition, the final quantities of key odorants in both types of samples were quite comparable. Hence, the refined biomimetic approach was validated as a valuable tool in studying different aspects of flavor formation upon coffee roasting.

2-Acetylpyrazine, also known as 1-pyrazinylethanone or fema 3126, belongs to the class of organic compounds known as aryl alkyl ketones. These are ketones have the generic structure RC(=O)R’, where R = aryl group and R’=alkyl group. 2-Acetylpyrazine exists as a solid, soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 2-acetylpyrazine is primarily located in the cytoplasm. 2-Acetylpyrazine has a bitter, bread crust, and chip taste.
2-acetylpyrazine is a pyrazine that is substituted by an acetyl group at position 2. It has been identified as one of the volatile flavor constituents in popcorn, bread crust, vinegar, and potato snacks. It has a role as a flavouring agent. It is an aromatic ketone and a member of pyrazines.
2-Acetylpyrazine is a nitrogen containing compound that has been used in biological studies. 2-Acetylpyrazine has been shown to have inhibitory properties against the growth of prostate cancer cells and other cell lines. It also inhibits the production of fatty acids and epidermal growth factor, which are important for cellular proliferation. The inhibition is due to the photochemical properties of 2-acetylpyrazine, which cause the formation of reactive species that react with biological molecules. The reactive species may be generated by either a reaction mechanism or a reaction pathway that involve coordination geometry. 2-acetylpyrazine has also been used as a fluorescence probe for fatty acid detection in lipid bilayers and liposomes., Name: Acetylpyrazine
