In this study, we attempted the chemical simplification of Psammaplin (PsA), while retaining its activity in vitro . Inspired by the previous Structure Activity Relationship (SAR) studies on various PsA analogues and relying on the fact that oxime is metabolically unstable, we initially designed and synthesized a diverse library of PsA analogues and evaluated for cytotoxic activity. Among 32 compounds of Psammaplin analogues synthesized, the compound 10b was almost equally active as parent Psammaplin in vitro. (C) 2020 Elsevier B.V. All rights reserved.

The first stereoselective, near-equimolar, and metal-free oxidative bioconjugation of amino acids and oligopeptides to aldehydes is presented. Based on a newly developed organocatalytic oxidative concept, the C-terminal and side-chain carboxylic acid functionalities of amino acids and oligopeptides are shown to couple in a stereoselective manner to alpha-branched aldehydes catalyzed by a chiral primary amine and a quinone as oxidizing agent. The oxidative coupling generally proceeds in high yield. For aspartic acid, selective coupling of the side-chain, or the C-terminal carboxylic acid, is demonstrated depending on the protection strategy. The stereoselective, oxidative bioconjugation concept is extended to a series of oligopeptides where coupling to carboxylic acid functionalities is presented. Bioorthogonal linker molecules for further functionalization are obtained by merging the oxidative coupling strategy with the click concept. It is demonstrated that the configuration of the new stereocenter is determined exclusively by the organocatalyst.

A quinoxaline-based porous organic polymer (Q-POP) as a mesoporous organic copolymer was developed as a new platform for the immobilization of CuNPs and copper nanocrystals. The prepared materials were characterized by FT-IR, XRD, N-2 adsorption-desorption isotherms, ICP, TGA, SEM, HR-TEM, EDX, and single-crystal X-ray crystallography. The obtained catalyst presented extraordinary catalytic activity towards Ullmann C-O coupling reactions with high surface area, hierarchical porosity, and excellent thermal and chemical stability. Due to its high porosity, and synergistic effect of copper nanocrystals incorporated in the polymer composite, the as-synthesized catalyst was successfully utilized for the Ullmann C-O coupling reaction of phenols and different aryl halides to prepare various diaryl ether derivatives. All types of aryl halides (except aryl fluorides) were screened in the Ullmann C-O coupling reaction with phenols to produce diaryl ethers in good to excellent yields (70-97 %), and it was found that aryl iodides have the best results. Besides, due to the strong interactions between CuNPs, N, and O-atoms of quinoxaline moiety existing in the polymeric framework, the copper leaching from the support was not observed. Furthermore, the catalyst was recycled and reused for five consecutive runs without significant activity loss.

A novel facile synthetic method for producing diphenylmethyl (DPM) ethers from 2-diphenylmethoxypyridine was developed. A variety of DPM ethers was successfully achieved with high yield via treatment of alcohols with 2-diphenylmethoxypyridine in the presence of catalytic FeCl3. The procedure is a practical and efficient synthetic procedure to protect various alcohols, and it can be applied to prepare bioactive compounds.

The Name is 4-Methoxybenzaldehyde. Through research, I have a further understanding and discovery of 123-11-5.

Phenylpropanoids, common natural compounds, possess many different biological activities such as antioxidant, anti-inflammatory and antiviral. Spring viraemia of carp virus (SVCV) can cause a high mortality in common carp (Cyprinus carpio). However, there are currently no licenced drugs that effectively cure this disease. In this study, we designed and synthesized a phenylpropanoid derivative 4-(4-methoxyphenyl)-3,4-dihydro-2H-chromeno[4,3-d]pyrimidine-2,5(1 H)-dione (E2), and explored the antiviral effect against SVCV in vitro and in vivo. Up to 25 mg/L of E2 significantly inhibited the expression levels of SVCV protein genes in the epithelioma papulosum cyprini (EPC) cell line by a maximum inhibitory rate of >90%. As expected, E2 remarkably declined the apoptotic of SVCV-infected cells and suppressed potential enhancement of the mitochondrial membrane potential (Delta Psi m), these data implied that E2 could protect mitochondria from structural damage in response to SVCV. Meanwhile, E2 was added to EPC cells under four different conditions: time-of-addition, time-of-removal, pre-treatment of viruses and pre-treatment of cells indicated that E2 may block the post-entry transport process of the virus. Additionally, the up-regulation of six interferon (IFN)-related genes also demonstrated that E2 indirectly activated IFNs for the clearance of SVCV in common carp. Drug cure effect showed that treatment with E2 at 0.5 d post infection (dpi) is more effective than at 0, 1 or 2 dpi. Most importantly, intraperitoneal therapy of E2 markedly improved common carp survival rate and reduced virus copies in body. Therefore, the E2 has potential to be developed into a novel anti-SVCV agent.

A novel series of 7,8-dichlorobenzofuro[3,2-c]quinoline-6,9,10(5H)-triones was obtained regioselectively in good yields. The products were formed by the reactions of the 4-hydroxy-2(1H)-quinolinones with 3,4,5,6-tetrachloro-1,2-benzoquinone in tetrahydrofuran as the solvent. Infrared, nuclear magnetic resonance (two-dimensional nuclear magnetic resonance), mass spectra and elemental analysis were used to elucidate the structures of new compounds.

Sturgeon (Acipenser sinensis) meat has not been fully utilised due to quality defects which were raised by Chinese sturgeon processing industry. This study was aimed to develop a high-quality sturgeon meat product and the effect of fermentation on qualities was studied. Results showed that fermentation with Saccharomyces cerevisiae could enhance ‘mushroom’, ‘fruity’ and ‘chocolate’ flavour by 1-octen-3-ol, ethyl acetate and 3-methyl-butanal; and enrich flavour through mild lipid oxidation and hydrolysis. In addition, fermentation could give an attractive colour with higher a*, b* and L* value. Texture properties were also improved with higher hardness, springiness, gumminess and chewiness. Higher free amino acids, TCA-soluble peptides and taste score in fermented sturgeon meat indicated better flavour and taste. The organoleptic evaluation suggested an overall satisfactory of wine-aroma sturgeon meat by fermentation with S. cerevisiae.

Despite common perception, the use of strong bases in Wittig chemistry is utterly unnecessary: we report a series of novel ion-pair phosphonium carboxylate reagents which are essentially storable ylides. These reagents are straightforwardly prepared in excellent yields, and their fluxional nature permits clean olefination of a broad range of aldehydes and even hemiacetals.

Presented here is a highly efficient procedure for the selective hydrogenation of aldehydes in the presence of ketones and its application in equilibrium displacement in a one-enzyme procedure catalysed by.-transaminase. A palladium-based heterogeneous catalyst was chemically synthesized from K2PdCl4 and 1,1′-binaphthyl-2,2′-ylenediamine and found to be suitable for selective hydrogenation of aldehydes using H2 of 1 atm, with a wide spectrum of aldehydes being efficiently and selectively reduced to the corresponding alcohols with a selectivity of up to 99%. This catalyst and its developed procedure can be successfully applied in pushing the equilibrium to product formation during transamination in a.-transaminase-promoted one-enzyme procedure via hydrogenation of the co-product, and an array of chiral amines was afforded in good to excellent yields of up to 99% with ees of up to > 99%.
