A new hemicyanidine-based colorimetric-fluorescent probe L (I) has been synthesized and characterized by x-ray single crystal diffraction, NMR, HRMS and other technologies. The probe L serves as a “”turn-on”” probe for the detection of Fe3+ and Al3+ ions in DMF-HEPES system with a high sensitivity and an excellent selectivity. The probe L manifesting the color of the solution containing L turns red on the addition of Fe3+, and turns pink on the addition of Al3+. The fluorescence turn-on detection of Fe3+ and Al3+ ions is attributed to the photo-induced electron transfer (PET) process and the exertion of the chelation-enhanced fluorescence effect (CHEF) mechanism. The results of thin layer silica gel plate coloration experiments also present the same characteristics. Addnl., further the probe L exhibit good cell permeability and could be employed to monitor Fe3+ and Al3+ ions in the living cells.

Marques, Joao Paulo Cordeiro; Rios, Italo Castro; Arruda, Tathilene Bezerra Mota Gomes; Rodrigues, Francisco Eduardo Arruda; Uchoa, Antonia Flavia Justino; Tavares de Luna, Francisco Murilo; Cavalcante, Celio Loureiro; Ricardo, Nagila Maria Pontes Silva published the artcile< Potential Bio-Based Lubricants Synthesized from Highly Unsaturated Soybean Fatty Acids: Physicochemical Properties and Thermal Degradation>, SDS of cas: 104-76-7, the main research area is lubricant soybean fatty acid.

The use of mineral lubricants and petroleum derivatives has become, along the years, harmful to the environment, so renewable raw materials have gained expressive notoriety. The innovation of this study is to understand how the highly unsaturated content from soybean oil influences the physicochem. properties and the thermal behavior of synthesized biolubricant base stocks. The process used was carried out in three steps: esterification with 2-ethylhexanol, epoxidation, and oxirane ring opening with 2-ethylhexanol. The modifications were monitored by 1H NMR, the main physicochem. properties were measured, and the thermogravimetric behaviors of products were evaluated. The synthesized samples had high viscosity indexes (VI > 120) and viscosities that fit in application grade ISO-32. The samples using highly unsaturated fatty acids had a better pour point (-12 °C). The raw material composition directly influenced the physicochem. properties but did not affect the thermogravimetric behavior.

Bae, Kideog; Zheng, Wei; Ma, Ying; Huang, Zhiwei published the artcile< Real-Time Monitoring of Pharmacokinetics of Mitochondria-Targeting Molecules in Live Cells with Bioorthogonal Hyperspectral Stimulated Raman Scattering Microscopy>, HPLC of Formula: 10602-04-7, the main research area is raman scattering microscopy mitochondria pharmacokinetics live cells.

The dynamics of mitochondria in live cells play a pivotal role in biol. events such as cell metabolism, early stage apoptosis, and cell differentiation. Triphenylphosphonium (TPP) is a commonly used mitochondria-targeting agent for mitochondrial studies. However, there has been a lack of understanding in intracellular behaviors of TPP in the course of targeting mitochondria due to the difficulty in tracking and quantifying small mols. in a biol. environment. Here, we report the utility of hyperspectral stimulated Raman scattering (SRS) microscopy associated with a Raman tag synthesized for real-time visualization and quantitation of TPP dynamics within live cells at the subcellular level. With the myriad of merits offered by a synthesized aryl-diyne-based Raman tag such as excellent photostability, negligible background interferences, and a linear dependence of the SRS signal on the TPP concentration, we successfully establish a quant. model to associate the mitochondrial membrane potential with the key pharmacokinetic parameters of TPP inside the live cells. The model reveals that reduction in the mitochondrial membrane potential leads to significant decreases in both the uptake rate and intracellular concentrations of TPP. Further, on the basis of the multiplexed SRS images concurrently highlighting the cellular proteins and lipids without further labeling, we find that the TPP uptake causes little cytotoxicity to the host cells. The bioorthogonal hyperspectral SRS microscopy imaging reveals that TPP can maintain stable affinity to mitochondria during the restructuring of mitochondrial networking, demonstrating its great potential for real-time monitoring of pharmacokinetics of small mols. associated with live biol. hosts, thereby promoting the development of mitochondria-targeting imaging probes and therapies in the near future.

The functionalized 3,4-dihydroquinolin-2-ones I (R1 = Me, 4-MeOC6H4CH2, 4-BrC6H4CH2, 4-MeSC6H4CH2, 2-furylmethyl; R2 = H, Cl; R3 = H, Me, MeO; R4 = H, CF3) have been assembled in good to high yields through the sequential reaction of readily available N-Ts-o-aminobenzyl alcs.

Highly diastereoselective synthesis of trans-3-R1-4-phenyl-1-tosyl-3,4-dihydroquinolin-2(1H)-ones was accomplished from 2-(tosylamino)-α-phenylbenzenemethanol under the same reaction conditions. Regarding the reaction mechanism, the formation of dihydroquinolones proceeds through the in situ generation of aza-o-QMs followed by conjugate addition of enolate/cyclization/elimination of acetone and CO2.

Greenhill, John V.; Ramli, Mohamed; Tomassini, Therezinha published the artcile< Reduction of enaminones in the preparation of 3-aminocyclohexanols. Novel preparation of tetronic acid>, Formula: C6H13NO, the main research area is aminocyclohexanol; cyclohexanol amino; reduction enaminone; tetronate.

Reduction of enaminones by Raney Ni gave the corresponding 3-aminocyclohexanols, of which the major product was trans when the substrate was N-unsubstituted. Thus 3-aminocyclohex-2-enone gave 75% of a 59:31 mixture of trans- and cis-3-aminocyclohexanol. The position of attack of NH3 on 2-acetylcyclopentanone and -hexanone was elucidated by reduction of the derived enaminones. The base attacked the side-chain CO in the former case but in the latter the ring CO was attacked. Reduction of 2-(substituted amino)fumaric esters gave enaminone analogs of tetronic acid (I), which on hydrolysis gave I.

Feng, Zhihui; Li, Yifan; Li, Ming; Wang, Yijun; Zhang, Liang; Wan, Xiaochun; Yang, Xiaogen published the artcile< Tea aroma formation from six model manufacturing processes>, Category: alcohols-buliding-blocks, the main research area is tea aroma formation processing; Aroma character impact; Precursors; Quantitative SPME; Tea aroma; Tea processing; Tea types; Volatiles.

Tea aroma is determined by the nature of the plant, the production processes, and many other factors influencing its formation and release. The objective of this study was to investigate the impact of manufacturing processes on the aroma composition of tea. Fresh tea leaves from the same cultivar and growing area were selected for producing the six types of tea: green, white, yellow, oolong, black, and dark teas. Comprehensive anal. by gas chromatog. mass spectrometry (GC/MS) was performed for the volatiles of tea infusion, prepared by solid-phase microextraction (SPME), solid-phase extraction (SPE), and solvent assisted flavor evaporation (SAFE). A total of 168 volatile compounds were identified. Black tea has the highest volatile concentration of 710 μg/g, while green tea has the lowest concentration of 20 μg/g. Significantly affected by these processes, tea aroma mols. are formed mainly from four precursor groups: carotenoids, fatty acids, glycosides, and amino acids/sugars.

Ma, Shuai; Cui, Jing-Wang; Rao, Cai-Hui; Jia, Meng-Ze; Chen, Yun-Rui; Zhang, Jie published the artcile< Boosting activity of molecular oxygen by pyridinium-based photocatalysts for metal-free alcohol oxidation>, HPLC of Formula: 403-41-8, the main research area is boosting oxygen pyridinium photocatalyst metal alc oxidation.

An eco-friendly and economical approach for the photocatalytic oxidation of organic inter-mediates by air under mild conditions is highly desirable in green and sustainable chem., where the photogeneration of active oxygen species plays a key role in improving conversion efficiency and selectivity. By using pyridinium derivatives as mol. mediators for electron transfer and energy transfer, the simultaneous activation of O2 from air into superoxide radicals and singlet oxygen species can be achieved, and a photoinduced electron transfer catalytic system for the oxidation of alcs. has been developed. Thus, we have successfully simplified the complicated catalytic system into a single mol. catalyst without any addnl. noble metals and co-catalysts/additives. The current photocatalytic system shows high catalytic efficiency not only for aromatic alcs. but also for aliphatic alcs. that are generally difficult to undergo aerobic oxidation at room temperature under air atm., representing an ideal photocatalytic platform for green and economical organic syntheses.
