Novel derivatives of quinolizidine alkaloid (-)-cytisine were synthesised. ADME properties, cytotoxicity against HEK293 cells and activity against viruses of influenza A/California/07/09(H1N1)pdm09 virus (IAV) and human parainfluenza virus type 3 (HPIV3) were evaluated. It was shown, that 9-carboxamides of methylcytisine (with phenyl and allyl urea’s fragments) are most active compounds against IAV probably due to predicted in silico peculiarity of their interactions with the 4R7B active site of IAV neuraminidase. Indexes of selectivity (SI) calculated as ratio of CC50/IC50 of these ureas are 47 and 59 correspondingly. It was also found, that derivatives obtained from allyl isocyanate and (-)-cytisine or 9,11-dibromocytisine are able to inhibit a reproduction of HPIV3 with SI = 58 and 95. Moreover, last compound – (1 R,5R)-N-allyl-9,11-dibromo-8-oxo-1,5,6,8-tetrahydro-2H-1,5-methanopyrido[1,2-a][1,5]diazocine-3(4H)-carboxamide with two bromine atom in 2-pyridone core of starting (-)-cytisine molecule, demonstrated high activity against HPIV3 (SI = 95) and moderate activity against IAV (SI = 16).

The quadrupolar interaction experienced by the spin-1 N-14 nucleus is known to be extremely sensitive to local structure and dynamics. Furthermore, the N-14 isotope is 99.6% naturally abundant, making it an attractive target for characterisation of nitrogen-rich biological molecules by solid-state NMR. In this study, dynamic nuclear polarization (DNP) is used in conjunction with indirect N-14 detected solid-state NMR experiments to simultaneously characterise the quadrupolar interaction at multiple N-14 sites in the backbone of the microcrystalline protein, GB3. Considerable variation in the quadrupolar interaction (>700 kHz) is observed throughout the protein backbone. The distribution in quadrupolar interactions observed reports on the variation in local backbone conformation and subtle differences in hydrogen-bonding; demonstrating a new route to the structural and dynamic analysis of biomolecules.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 74-79-3. Product Details of 74-79-3.

A two-dimensional molybdenum disulfide (MoS2) nanosheet, as a new type of inorganic material with high hydrophobicity and excellent physicochemical stability, holds great application potential in the preparation of a high separation performance organic-inorganic hybrid membrane. In this work, high hydrophobic MoS2 was embedded in hydrophobic polyether copolymer block amide (PEBA) to prepare PEBA/MoS2 organic-inorganic hybrid membranes. The structure, morphology, and hydrophobicity of the hybrid membrane were characterized by scanning electron microscopy, thermogravimetric analysis, contact angle goniometry, X-ray diffraction, infrared spectroscopy analysis, and atomic force microscopy. The effect of embedding of MoS2 on the swelling degree and pervaporation separation performance of the PEBA/MoS2 hybrid membrane was studied with a 1.0 wt % pyridine dilute solution. The results indicated that with increasing the MoS2 content, the separation factor of PEBA/MoS2 increased first and then decreased, while it showed a downward trend in the permeation flux. When the MoS2 content in the PEBA/MoS2 hybrid membrane was 10.0 wt %, the permeation flux was 83.4 g m(-2)h(-1) (decreased by 21.5% compared with the pure PEBA membrane), and the separation factor reached a maximum value of 11.11 (increased by 37.6% compared with the pure PEBA membrane) Meanwhile, the effects of feed temperature on the pervaporation separation performance of PEBA/MoS2 hybrid membranes were also studied. In addition, as the PEBA/MoS2 hybrid membrane has excellent thermal stability, it is expected to be a promising material for recovering pyridine from wastewater.

G-protein-coupled-receptor (GPCR) signaling is exquisitely controlled to achieve spatial and temporal specificity. The endogenous protein kinase inhibitor peptide (PKI) confines the spatial and temporal spread of the activity of protein kinase A (PKA), which integrates inputs from three major types of GPCRs. Despite its wide usage as a pharmaceutical inhibitor of PKA, it was unclear whether PKI only inhibits PKA activity. Here, the effects of PKI on 55 mouse kinases were tested in in vitro assays. We found that in addition to inhibiting PKA activity, both PKI (6-22) amide and full-length PKI alpha facilitated the activation of multiple isoforms of protein kinase C (PKC), albeit at much higher concentrations than necessary to inhibit PKA. Thus, our results call for appropriate interpretation of experimental results using PKI as a pharmaceutical agent. Furthermore, our study lays the foundation to explore the potential functions of PKI in regulating PKC activity and in coordinating PKC and PKA activities.

Although silicon is one of the most prospective alternatives with ultrahigh theoretical capacity, its significant intrinsic volume changes seriously restricts its practical applications. Herein, a water-soluble polymer binder with a three dimensional (3D) network is exploited for stable silicon (Si) anode via in-situ thermal cross-linking of xanthan gum (XG) with polyacrylamide (PAM). Moreover, the cross-linked structure of c-XG-PAM gel binder with hydroxyl groups and amide groups remarkably enhances the adhesion on silicon and Cu current collector. As a result, the c-XG-PAM binder offers appealing electrochemical performance for SiNP electrodes (1104 mAh g(-1) after 1000 cycles) and SiC electrodes (stabilizing for over 400 cycles). The gel polymer binder provides a prospective avenue for pursuing the elongated cycling life of high capacity battery electrodes.

Efficient and general one-pot trifluoromethylative functionalization of amides has been accomplished for the synthesis of various trifluoromethylated bis(indolyl)arylmethane, utilizing trifluoromethyltrimethylsilane and substituted indoles as nucleophiles. The developed reaction involves the in situ generation and trapping of a trifluoromethylated iminium ion, derived from the trifluoromethylated hemiaminal of amide, with various substituted indoles. This method has been successfully extended to the synthesis of diverse trifluoromethylated triarylmethanes employing phenols as nucleophiles. Furthermore, the potential of the method was demonstrated via the two-step synthesis of a trifluoromethylated analog of a hypolipidemic and anti-obesity agent.

YEATS-domain-containing MLLT1 is an acetyl/aryl-lysine reader domain, which is structurally distinct from well-studied bromodomains and has been strongly associated in development of cancer. Here, we characterized piperazine-urea derivatives as an acetyl/acyl-lysine mimetic moiety for MLLT1. Crystal structures revealed distinct interaction mechanisms of this chemotype compared to the recently described benzimidazole-amide based inhibitors, exploiting different binding pockets within the protein. Thus, the piperazine-urea scaffold offers an alternative strategy for targeting the YEATS domain family.

Once removed from the sea, some plastics cannot be recycled or reused. This debris has high calorific value which makes it suitable to use as fuel. For this reason, a mixture of plastic materials was subjected to hydrothermal carbonization using seawater as solvent. We could thus examine the characteristics of the final products obtained and test the feasibility of converting marine plastic debris into fuel. Results showed that raising the temperature of the process reduced the inorganic anions content and increased hydrochar NCV. In addition, thermobalance was used to look for differences in the thermal decomposition of the different solid residues, being hydrochar at 300 degrees C the most affected material. The content of inorganic compounds in the HTC-liquor increases as the process temperature rose. Amides, alcohols and alkanes were the main organic compounds found in all cases. Gases emissions also increased with temperature.

Recently, mechanical ball milling was applied to chitin depolymerization. The mechanical activation afforded higher selectivity toward glycosidic bond cleavage over amide bond breakage. Hence, the bioactive N-acetylglucosamine (GlcNAc) monomer was preferentially produced over glucosamine. In this regard, the force-dependent mechanochemical activation-deactivation process in the relaxed and pulled GlcNAc dimer undergoing deacetylation and depolymerization reactions was studied. For the relaxed case, the activation energies of the rate-determining steps (RDS) proved that the two reactions could occur simultaneously. Mechanical forces associated with ball milling were approximated with linear pulling and were introduced explicitly in the RDS of both reactions through force-modified potential energy surface (FMPES) formalism. In general, as the applied pulling force increases, the activation energy of the RDS of deacetylation shows no meaningful change, while that of depolymerization decreases. This result is consistent with the selectivity exhibited in the experiment. Energy and structural analyses for the depolymerization showed that the activation can be attributed to a significant change in the glycosidic dihedral at the reactant state. A lone pair of the neighboring pyranose ring O adopts a syn-periplanar conformation relative to the glycosidic bond. This promotes electron donation to the sigma*-orbital of the glycosidic bond, leading to activation. Consequently, the Bronsted-Lowry basicity of the glycosidic oxygen also increases, which can facilitate acid catalysis.

Although ionic liquids (ILs) have been widely explored as promising solvents for carbon capture, system-atic study on the rational selection and design of ILs for carbon capture processes is still scarce. In this contribution, a comprehensive literature survey is first performed to provide an up-to-date database comprising 10,116 CO2 solubility data and 463 H-2 solubility data measured in a large number of ILs at various temperatures and pressures. Using this dataset, the UNIFAC-IL model for predicting the vapor- liquid equilibrium of the CO2-H-2-IL ternary system is developed, where 42 main groups and 53 subgroups are specified and 220 group interaction parameters are fitted. With this model, an optimization-based computer-aided ionic liquid design problem is finally formulated and solved to identify the best ILs for the pre-combustion carbon capture process. It is found that the hydroxyl-ammonium and hydroxylimidazolium bis(trifluoromethylsulfonyl)amide ILs are the most promising solvent candidates. (C) 2020 Elsevier Ltd. All rights reserved.
