Silyanova, Eugenia A. published the artcileFormation of 3,4-Diarylpyrrole- and Pyrrolocoumarin Core of Natural Marine Products via Barton-Zard Reaction and Selective O-Demethylation, COA of Formula: C9H10O3, the main research area is diarylpyrrole pyrrolocoumarin lamellarin core preparation Barton Zard selective demethylation.

A metal-free approach to 3,4-diarylpyrrole-2-carboxylate and pyrrolocoumarin cores of lamellarins and related natural products based on Barton-Zard reaction of nitrostilbenes with Et isocyanoacetate was developed. In the case of diarylpyrrole-2-carboxylates with a 3-(o-methoxyphenyl) fragment, treatment with 1 equivalent of BBr3 resulted in selective O-demethylation of the ortho-methoxy group, while other methoxy groups in the mol. remained intact. The resulting 3-(2-hydroxyphenyl)pyrrole-2-carboxylates underwent base-induced lactonization to form the target pyrrolocoumarins.

Murugesan, Kathiravan published the artcileHomogeneous cobalt-catalyzed reductive amination for synthesis of functionalized primary amines, Application In Synthesis of 1205-17-0, the main research area is carbonyl compound ammonia cobalt catalyst reductive amination; primary amine preparation.

The combination of cobalt and linear-triphos (bis(2-diphenylphosphinoethyl)phenylphosphine) as the molecularly-defined non-noble metal catalyst for the synthesis of linear and branched benzylic, heterocyclic and aliphatic primary amines from carbonyl compounds, gaseous ammonia and hydrogen in good to excellent yields was reported. Noteworthy, this cobalt catalyst exhibited high selectivity and as a result the -NH2 moiety was introduced in functionalized and structurally diverse mols. An inner-sphere mechanism on the basis of the mono-cationic [triphos-CoH]+ complex as active catalyst was proposed and supported with d. functional theory computation on the doublet state potential free energy surface and H2 metathesis was found as the rate-determining step.

Wang, Weigang published the artcileOrganic compounds evolution and sludge properties variation along partial nitritation and subsequent anammox processes treating reject water, Safety of 2,3-Dimethoxybenzaldehyde, the main research area is organic compound sludge nitritation anammox wastewater treatment; Denitrification; Nitrogen removal; Organic compounds evolution; Partial nitritation-anammox; Reject water.

Reject water contains complex components of organic compounds, which have significant influences on the nitrogen removal performance when treated using biol. autotrophic nitrogen removal technol. In this study, a two-stage partial nitritation (PN)-anammox (floc-granule) system was established to treat reject water (COD/NH+4-N = 0.97 ± 0.15), and the evolution of organic compounds along PN and annamox bioreactors was investigated using gas chromatog.-mass spectrometry and excitation-emission matrix. Also, the variation of PN and anammox sludge properties relating to COD reduction was examined The PN-anammox system removed approx. 80% of total inorganic nitrogen and COD with hydraulic reaction time of 16 h. The influent organics (330-600 mg COD/L) in reject water were primarily composed of volatile, protein-like and humic acid-like organic compounds PN process contributed 53 ± 18% of the overall COD removal, primarily including oxygen-containing organics (e.g. phenol), proteins and humic acids. Anammox process contributed 22 ± 15% of the overall COD removal, but large mol. acids (e.g. lactic acid) and small mol. alcs. (e.g. glycerol) were reoccurred, contributing to the effluent COD with recalcitrant hydrocarbons (e.g. n-Octadecane). Reject water increased the extracellular proteins/polysaccharides ratio of PN and anammox sludge, promoting the adsorption and degradation of organic compounds High-throughput sequencing results showed that denitrifying bacteria of Ottowia increased from 0.03% to 14.4% in PN reactor, and of Denitratisoma increased from 9.6% to 15.4% in anammox reactor. The occurrence of these denitrifiers might mitigate the neg. impact of organics to functional organisms. This study highlights the organics fate during PN-anammox treatment system, which is important to maintain the robust nitrogen removal when treating organics-containing and high ammonium concentration wastewater.

Yang, Yang published the artcileStructure-activity relationship study of DEL-22379: ERK dimerization inhibitors with increased safety, Synthetic Route of 104-01-8, the main research area is lung liver cancer DEL22379 anticancer agent ERK signaling; Anti-cancer activity; ERK dimerization inhibitor; Indolin-2-one; Structure–activity relationship; Synthesis.

Abstract: Aberrant activation of ERK signaling pathway usually leads to oncogenesis, and small mol. agents targeting this pathway are impeded by the emergence of drug resistance due to reactivation of ERK signaling. Compound DEL-22379 has been reported to inhibit ERK dimerization which was unaffected by drug-resistant mechanism reactivating the ERK signaling. Here, we discussed a structure-activity relationship study of DEL-22379. Forty-seven analogs were designed and synthesized. Each synthesized compound was biol. evaluated for their inhibitory rates on several tumor cell lines and compounds with high inhibitory rates were further evaluated for IC50 values. The structure-activity relationship of idolin-2-one scaffold and the impact of Z/E configuration on potency were discussed. Potential safety of two synthesized analogs was investigated and in silico docking study of five compounds was performed to understand the structural basis of ERK dimerization inhibition.

Wei, Quanzeng published the artcileSearch for potential molecular indices for the fermentation progress of soy sauce through dynamic changes of volatile compounds, Synthetic Route of 21834-92-4, the main research area is soy sauce fermentation volatile compound.

To date, the fermentation progress and maturity of soy sauce are mainly judged by olfactory and individual experiences, which are subjective and lack quality control. In this study, dynamic changes of volatile compounds during soy sauce fermentation were profiled to search for mol. indexes of fermentation progression. In total, 119 volatile compounds were identified and quantified by headspace solid-phase microextraction gas chromatog.-mass spectrometry. Principal component anal. (PCA) revealed the compounds that contributed most to the distinction of various stages of fermentation progression; the list included 2-methoxy-4-vinylphenol, phenylethyl alc., phenylacetaldehyde, and benzaldehyde. The degradation of 2-methoxy-4-vinylphenol and the generation of phenylethyl alc. could remarkably discriminate between the discrete stages of soy sauce fermentation It therefore suggests that their group was a refined and potential index to indicate the progression of the soy sauce fermentation This work furthers our understanding of the mol. changes occurring during soy sauce fermentation and improves its quality control and process management.

Xue, Jinjin published the artcileIdentification of aroma-active compounds responsible for the floral and sweet odors of Congou black teas using gas chromatography-mass spectrometry/olfactometry, odor activity value, and chemometrics, Computed Properties of 21834-92-4, the main research area is black tea aroma compound odor GC MS olfactometry chemometrics; aroma-active compounds; congou black tea; floral odor; gas chromatography-mass spectrometry/olfactometry; sweet odor; terpenoid.

Floral and sweet odors are two typical characteristic aromas of Congou black tea, but their aroma-active compounds are still unclear. Characterizing the key aroma-active compounds can provide a theor. foundation for the practical aroma quality evaluation of Congou black tea and directional processing technol. of high-quality black tea with floral or sweet odors. Gas chromatog.-olfactometry (GC-O) combined with odor activity value (OAV) is often used to screen key aroma-active substances, but the interaction between aroma components and their impact on the overall sensory quality is ignored. Therefore, in this study, OAV combined with variable importance in projection (VIP) and Spearman correlation anal. (SCA) were used to characterize the aroma-active components of Congou black teas with floral and sweet odors. Eighty-five volatiles were identified in these samples using gas chromatog.-mass spectrometry (GC-MS). Twenty-three compounds were identified as potential markers for the floral and sweet odors of Congou black teas from orthogonal partial least squares discriminant anal. (OPLS-DA). Eighteen compounds were selected as candidate aroma compounds based on GC-O anal. and OAV calculations In addition, 26 compounds were screened as crucial aroma compounds based on SCA. Finally, 19 compounds were evaluated as key aroma compounds by the comprehensive evaluation of VIP, OAV, and SCA. Terpenoids are the main active compounds that contribute to the floral odor of Congou black tea, whereas aldehydes are the key compounds for the sweet odor. The proposed method can effectively screen the aroma-active compounds and can be used for comprehensive quality control of products. 2022 Society of Chem. Industry.
