A one-pot direct synthesis of a wide range of biologically active benzimidazoles through coupling of phenylenediamines and aldehydes catalyzed by a highly recyclable nonnoble cobalt nanocomposite was developed. A broad set of benzimidazoles can be efficiently synthesized in high yields and with good functional-group tolerance under additive- and oxidant-free mild conditions. The catalyst can be easily recycled for successive uses, and the process permits gram-scale syntheses of benzimidazoles.

Cobalt complexes containing a salen-type pyridoxal ligand with pyridine were synthesized as a new Co (III) catalytic system for the cycloaddition of carbon dioxide. Two cobalt(III) complexes possessing a salen-type pyridoxyl ligand were synthesized by the reaction of pyridoxal ligands (pyr(2)en = (N,N’-bis (pyridoxylideneiminato)ethylene) and pyr(2)cy = (N,N’-bis(pyridoxylideneiminato)cyclohexane)) and Co (OAc)(2) and characterized by various analytical methods, including infrared spectroscopy and high-resolution mass analysis. Single-crystal X-ray crystallography analysis confirmed that the cobalt pyr(2)en complex had a distorted octahedral structure: the tetradentate Schiff base ligand binds the cobalt metal in one plane, and the metal center adopts an octahedral geometry by the additional coordination of acetate and dimethyl sulfoxide. The synthesized complexes were used as catalysts in the cycloaddition of carbon dioxide (CO2) to propylene oxide. The catalysts showed high activity for cycloaddition between CO2 and epoxides, even at a low loading (0.5 mol%), in the presence of various cocatalysts. (C) 2020 Elsevier Ltd. All rights reserved.

A novel fluorescent probe, TCF-IPY, has been designed and developed for highly selective and ratiometric detection of GSH based on the extend of the pi-conjugation system of imidazo[1,5-alpha]pyridine IPY-CHO. Upon addition of GSH, TCF-IPY displayed remarkable fluorescence variations (approximate 949-fold ratio changes) from 603 nm to 475 nm, thereby enabling GSH detection in a fine ratiometric manner. Moreover, TCF-IPY exhibited excellent selectivity toward GSH over other biologically related species including Cys and Hcy. The huge blue shifts both in absorption (259 nm) and emission spectra (128 nm), low cytotoxicity, high sensitivity (97 nM) and rapid response (240 s) of TCF-IPY make it a robust molecular tool for endogenous GSH investigation. Furthermore, TCF-IPY was also successfully used for ratiometric imaging of endogenous GSH in living MCF-7 cells and zebrafish.

In this study, the chemical and sensory profiles of 42 different nonalcoholic beer (NAB) brands/styles already on the global market and produced through several different brewing techniques were evaluated. A trained panel (i.e., 11 panelists) performed standard-driven descriptive and check-all-that-apply analyses in triplicate to sensorially characterize the aroma and taste/mouthfeel profiles of 42 commercial NABs, a commercial soda, and a commercial seltzer water (n = 44). These beers were also chemically deconstructed using several different analytical techniques targeting volatile and nonvolatile compounds. Consumer analysis (n = 129) was then performed to evaluate the Northern Californian consumer hedonic liking of a selection (n = 12) of these NAB brands. These results provide direction to brewers and/or beverage producers on which techniques they should explore to develop desirable NAB offerings and suggest chemical targets that are indicators of specific flavor qualities and/or preference for American consumers.

Inflammation is a complex biological response to stimuli. Activated macrophages induced excessively release of pro-inflammatory cytokines and mediators such as endogenous radical nitric oxide (NO) play a significant role in the progression of multiple inflammatory diseases. Both natural and synthetic chalcones possess a wide range of bioactivities. In this work, thirty-nine chalcones and three related compounds, including several novel ones, based on bioactive kava chalcones were designed, synthesized and their inhibitory effects on NO production in RAW264.7 cells were evaluated. The novel compound (E)-1-(2′-hydroxy-4′,6′-dimethoxyphenyl)-3-(3-methoxy-4-(3-morpholinopropoxy)phenyl)prop-2-en-1-one (53) exhibited a better inhibitory activity (84.0%) on NO production at 10 mu M (IC50 = 6.4 mu M) with the lowest cytotoxicity (IC50 > 80 mu M) among the tested compounds. Besides, western blot analysis indicated that compound 53 was a potent down-regulator of inducible nitric oxide synthase (iNOS) protein. Docking study revealed that compound 53 also can dock into the active site of iNOS. Furthermore, at the dose of 10 mg/kg/day, compound 53 could both significantly suppress the progression of inflammation on collagen-induced arthritis (CIA) and adjuvant-induced arthritis (AIA) models. In addition, the structure-activity relationship (SAR) of the kava chalcones based analogs was also depicted. (c) 2020 Elsevier Masson SAS. All rights reserved.

Selective cleavage of C & xe001;C bonds is highly important for the synthesis of carbonyl containing fine chemicals and pharmaceuticals. Novel methodologies such as ozonolysis reactions, Lemieux-Johnson oxidation reactionetc. already exist. Parallel to these, catalytic methods using homogeneous catalysts also have been discovered. Considering the various advantages of heterogeneous catalysts such as recyclability and stability, couple of transition metal-based heterogeneous catalysts have been applied for this reaction. However, the pharmaceutical industries prefer to use metal-free catalysts (especially transition metal-free) to avoid further leaching in the final products. This is for sure a big challenge to an organic chemist and to the pharmaceutical industries! To make this feasible, a mild and efficient protocol has been developed using polymeric carbon nitrides (PCN) as metal-free heterogeneous photocatalysts to convert various olefins into the corresponding carbonyls. Later, this catalyst has been applied in the gram scale synthesis of pharmaceutical drugs using direct solar energy. Detailed mechanistic studies revealed the actual role of oxygen, the catalyst, and the light source.

Recommanded Product: 500-22-1. The Name is 3-Pyridinecarboxaldehyde. Through research, I have a further understanding and discovery of 500-22-1.

Reductive amination is essential to the preparation of amines (e.g., pharmaceuticals and industrial products). This protocol shows how to prepare and use graphitic shell-encapsulated cobalt-based nanoparticles as catalysts for this reaction. Reductive aminations are an essential class of reactions widely applied for the preparation of different kinds of amines, as well as a number of pharmaceuticals and industrially relevant compounds. In such reactions, carbonyl compounds (aldehydes, ketones) react with ammonia or amines in the presence of a reducing agent and form corresponding amines. Common catalysts used for reductive aminations, especially for the synthesis of primary amines, are based on precious metals or Raney nickel. However, their drawbacks and limited applicability inspired us to look for alternative catalysts. The development of base-metal nanostructured catalysts is highly preferable and is crucial to the advancement of sustainable and cost-effective reductive amination processes. In this protocol, we describe the preparation of carbon-supported cobalt-based nanoparticles as efficient and practical catalysts for synthesis of different kinds of amines by reductive aminations. Template synthesis of a cobalt-triethylenediamine-terephthalic acid metal-organic framework on carbon and subsequent pyrolysis to remove the organic template resulted in the formation of supported single cobalt atoms and nanoparticles. Applying these catalysts, we have synthesized structurally diverse benzylic, aliphatic and heterocyclic primary, secondary and tertiary amines, including pharmaceutically relevant products, starting from inexpensive and easily accessible carbonyl compounds with ammonia, nitro compounds or amines and molecular hydrogen. To prepare this cobalt-based catalyst takes 26 h, and the reported catalytic reductive amination reactions can be carried out within 18-28 h.
