Alzheimer’s disease (AD) is a multifactorial neurological disorder involving complex pathogenesis. Single target directed drugs proved ineffective and since last few years’ different pharmacological strategies including multi-targeting agents are being explored for the effective drug development for AD. A total of 19 dipropargyl substituted diphenylpyrimidines have been synthesized and evaluated for the monoamine oxidase (MAO) and acetylcholinesterase (AChE) inhibition potential. All the compounds were found to be selective and reversible inhibitors of MAO-B isoform. These compounds also displayed good AChE inhibition potential with IC50 values in low micromolar range. AVB4 was found to be the most potent MAO-B inhibitor with IC50 value of 1.49 +/- 0.09 mu M and AVB1 was found to be the most potent AChE inhibitor with IC50 value of 135 +/- 0.03 mu M. In the ROS protection inhibition studies, AVB1 and AVB4 displayed weak but interesting activity in SH-SYSY cells. In the cytotoxicity studies involving SH-SY5Y cells, both AVB1 and AVB4 were found to be non-toxic to the tissue cells. In the molecular dynamic simulation studies of 30 ns, the potent compounds were found to be quite stable in the active site of MAO-B and AChE. The results suggested that AVB1 and AVB4 are promising dual inhibitors and have the potential to be developed as anti-Alzheimer’s drug. (C) 2019 Published by Elsevier Masson SAS.

Six fluorine-containing, mix-substituted phosphazene-based branched benzoxazine monomers with a low melting point were successfully prepared and their chemical structures were verified by H-1, C-13, P-31 and F-19 nuclear magnetic resonance (NMR). These branched benzoxazine resins underwent thermal ring-opening polymerization to form cured polymers with high thermal stability both in N-2 atmosphere and in air. The co-substituents, both m-CF3PhOH andp-CF3PhOH, imposed significant effects on processing, thermal, and surface properties of corresponding polybenzoxazines. Non-isothermal differential scanning calorimetry (DSC) under diverse heating rates was adopted to investigate the curing kinetics and determine the activation energy of polymerization. DSC results indicate that the m-CF3PhO-/p-CF3PhO- groups have the potential to lower ring-opening polymerization temperature. Glass transition temperatures (T(g)s) of polybenzoxazines derived from p-CF3PhOH are higher than that of polymers derived from m-CF3PhOH due to different steric hindrance and crosslinking density. More interesting, all polybenzoxazines show relatively high dielectric constant but exhibit low dielectric loss at ambient temperature.

Demidov, MR; Osyanin, VA; Osipov, DV; Klimochkin, YN in [Demidov, Maxim R.; Osyanin, Vitaly A.; Osipov, Dmitry, V; Klimochkin, Yuri N.] Samara State Tech Univ, Samara 443100, Russia published Three-Component Condensation of Pyridinium Ylides, beta-Ketonitriles, and Aldehydes with Divergent Regioselectivity: Synthesis of 4,5-Dihydrofuran-3-and 2H-Pyran-5-carbonitriles in 2021.0, Cited 41.0. The Name is 4-Methoxybenzaldehyde. Through research, I have a further understanding and discovery of 123-11-5.

A library of trans-4,5-dihydrofuran-3-carbonitriles was synthesized in a diastereoselective manner in good yields by the three-component reaction of beta-ketonitriles, carbonyl- and semistabilized pyridinium ylide precursors, and aldehydes in the presence of piperidine. This one-pot transformation generates two C-C and one C-O bond and proceeds through a cascade Knoevenagel condensation, a Michael addition, and intramolecular S(N)2 cyclization. Formation of cyclopropanecarbonitrile derivatives, which in some cases were obtained as major products, was found to be a competing reaction. The use of arylglyoxals changes regioselectivity and leads to 2-hydroxy-2H-pyran-5-carbonitriles.

Copper(I) complexes of the types [Cu(N-N)(PPh3)(2)]NO3(LC41-LC44) and [Cu(N-N)(PPh3)(NO3)] (LC45) carrying 3-substituted 1-pyridine-2-ylimidazo[1,5-a]pyridine (N-N) derivatives and triphenylphosphine (PPh3) ligands have been prepared. The synthesized copper(I)-phosphine complexes were fully characterized by NMR, IR, ESI-MS and UV-visible spectroscopy as well as by cyclic voltammetry. Selected structures such as LC42, LC43 and LC45 were additionally analysed by single-crystal X-ray method, which show that copper(I) centre adopts a highly distorted tetrahedral geometry. The(1)H and(13)C NMR spectral data of the complexes throw light on the nature of metal-ligand bonding. They display d pi-pi* metal-to-ligand charge transfer (MLCT) transition and show quasireversible Cu-I/Cu(II)metal oxidation. Among the copper(I)-phosphine complexes, LC41-LC44 exhibit moderate cytotoxicity (IC50: 24 h, 67-74 mu M; 48 h, 58-70 mu M) against human lung epithelial adenocarcinoma A549 cells, whereas LC45 displays the best activity (IC50: 24 h, 42 mu M; 48 h, 34 mu M) for A549 cancer cell line, which is better than that of the commercial antitumor drug cisplatin. All the complexes also displayed excellent selectivity by being relatively inactive against the human lung epithelial L132 normal cell line with selectivity index (SI) values ranging from 3.4 to 7.4. The complexes block cell cycle progression of A549 cells in G(0)/G(1)phase. FACSVerse analyses are suggestive of reactive oxygen species (ROS) generation and apoptotic cell death induced by the LC41, LC43 and LC45. The induction of apoptosis in A549 cells was shown by Annexin V with propidium iodide (PI) and 4 ‘,6-diamidino-2-phenylindole (DAPI) staining methods and established the ability of LC41, LC43 and LC45 to accumulate in the cell nuclei.

HPLC of Formula: C7H8O2. I found the field of Pharmacology & Pharmacy very interesting. Saw the article The tyrosinase-inhibitory effects of 2-phenyl-1,4-naphthoquinone analogs: importance of the (E)–phenyl-,-unsaturated carbonyl scaffold of an endomethylene type published in 2019.0, Reprint Addresses Moon, HR (corresponding author), Pusan Natl Univ, Coll Pharm, Busan 609735, South Korea.; Chun, P (corresponding author), Inje Univ, Coll Pharm, Gimhae 50834, Gyeongnam, South Korea.; Chun, P (corresponding author), Inje Univ, Inje Inst Pharmaceut Sci & Res, Gimhae 50834, Gyeongnam, South Korea.. The CAS is 150-19-6. Through research, I have a further understanding and discovery of m-Methoxyphenol.

In order to investigate the effect of the (E)–phenyl-,-unsaturated carbonyl scaffold of an endomethylene type on tyrosinase inhibition, 2-phenyl-1,4-naphthoquinone derivatives were synthesized by Michael addition of substituted benzenes to 1,4-naphthoquinone and subsequently an auto-oxidation. Most of the derivatives potently inhibited mushroom tyrosinase and four derivatives, including 1c (IC50=22.00 +/- 1.63M), more potently inhibited mushroom tyrosinase than kojic acid (IC50=37.86 +/- 2.21M). Cell-based assays using B16F10 cells (a melanoma cell line) showed 1c dose-dependently suppressed melanin production and more potently inhibited tyrosinase activity than kojic acid. Docking simulation results between 1c and tyrosinase and a kinetic study suggest that 1c is a competitive inhibitor that binds to the active site of tyrosinase. These results support that anti-melanogenic effect of naphthoquinone derivatives results from their tyrosinase inhibiting activity and the (E)–phenyl-,-unsaturated carbonyl scaffold of an endomethylene type can confer tyrosinase-inhibitory activity.

Molecular behavior under bilayer membrane environments is one of the important research topics concerning how organic molecules exert their biological activities when interacting with cellular membranes. However, chemistry-based approaches to this property have not been successful when compared with the structural biological strategy on ligand-receptor interactions. Here, we investigated the molecular behavior of the lipophilic ATPase inhibitor bafilomycin A(1) and its derivatives under a lipid environment from a chemical point of view. Our results revealed significant differences in membrane affinity and dynamics among ligands having different inhibitory potencies, suggesting the specific contribution of ligand-membrane interactions to their biological activity.

The effects of different paprikas on the sensory properties and the physicochemical properties of spiced beef were studied. Headspace solid phase microextraction and gas chromatography-mass spectrometry were used to identify the flavor substances in the samples. The results showed that the protein and fat content of the samples with paprika were higher compared to the blank group, which were 24.10-25.60 g/100 g and 3.40-3.70 g/100g, respectively. The scores of flavor and color in the blank group were 6.50 and 6.56, respectively, which were lower than the paprikas treatment group. Among the five paprika treatment groups, the color and taste scores of the samples treated with qixing paprika were higher, which were 8.00 and 8.07, respectively. A total of 145 volatile flavor substances were detected, compared with the control group, there were more volatile flavor substances in the paprika additive groups, indicated that paprika additive could enrich the flavor of spiced beef. Practical applications Paprika not only has a unique flavor, but also has good antioxidant properties. Spiced beef is popular among consumers. However, the surface color of the product is easy to change due to oxidation, which affects the color of the product, resulting in a decline in product sales and economic losses to the enterprise. In addition, the protein and fat of the product will be lost due to oxidation during processing. Therefore, the effects of different paprika on the color, nutritional value, and volatile flavors of spiced beef were studied. The purpose was to slow down the oxidation of products, improve the color of products, retain the nutritional value, and reduce the loss of enterprises by adding different capsicum. In addition, the volatile flavor of products will directly affect the sensory evaluation of consumers, so it is very important to understand the influence of pepper on volatile flavor compounds and consumption preference for volatile components.
