L-threonine aldolase (LTA) is a PLP-dependent enzyme that can reversibly catalyze aldol reaction of glycine and acetaldehyde to produce beta-hydroxy-alpha-amino acids. In the present work, a putative Ita gene from Actinocorallia herbida (AhLTA) was mined and over-expressed in Escherichia coli BL21 (DE3). The substrate spectrum assay indicated that AhLTA only used glycine as donor substrate and tolerated a wild range of aromatic aldehydes as acceptor substrates. It was found that the type and position of substituents in the aromatic aldehydes exerted a significant impact on the activity and stereoselectivity at beta-carbon of AhLTA. Among those substrates, AhLTA could catalyze glycine and 4-methylsulphonyl benzaldehyde (14a) to produce L-threo-4-methylsulfonylphenylserine ((2S,3R)-14b) with high conversion (94.4%) and moderate stereoselectivity (19% de). By conditional optimization, the de value of (2S, 3R)-14b was improved to 61% and the conversion was 75%. Taken together, our study suggested that AhLTA might be a promising catalyst for producing chiral beta-hydroxy-alpha-amino acids. (C) 2020 Elsevier Ltd. All rights reserved.

BackgroundLaminitis is a common and serve disease which caused by inflammation and pathological changes of the laminar junction. However, the pathologic mechanism remains unclear. In this study we aimed to investigate changes of the gut microbiota and metabolomics in oligofructose-induced laminitis of horses.ResultsAnimals submitted to treatment with oligofructose had lower fecal pH but higher lactic acid, histamine, and Lipopolysaccharide (LPS) in serum. Meanwhile, oligofructose altered composition of the hindgut bacterial community, demonstrated by increasing relative abundance of Lactobacillus and Megasphaera. In addition, the metabolome analysis revealed that treatment with oligofructose decreased 84 metabolites while 53 metabolites increased, such as dihydrothymine, N3,N4-Dimethyl-L-arginine, 10E,12Z-Octadecadienoic acid, and asparagine. Pathway analysis revealed that aldosterone synthesis and secretion, regulation of lipolysis in adipocytes, steroid hormone biosynthesis, pyrimidine metabolism, biosynthesis of unsaturated fatty acids, and galactose metabolism were significantly different between healthy and laminitis horses. Furthermore, correlation analysis between gut microbiota and metabolites indicated that Lactobacillus and/or Megasphaera were positively associated with the dihydrothymine, N3,N4-Dimethyl-L-arginine, 10E,12Z-Octadecadienoic acid, and asparagine.ConclusionsThese results revealed that disturbance of gut microbiota and changes of metabolites were occurred during the development of equine laminitis, and these results may provide novel insights to detect biomarkers for a better understanding of the potential mechanism and prevention strategies for laminitis in horses.

This work reports an efficient method for the oxidation reaction of aliphatic, aromatic allylic, and benzylic alcohols into aldehydes catalyzed by the cyclopentadienyl ruthenium(II) complex (RuCpCl(PPh3)(2)) with bubbled O-2. Through further optimizing controlled studies, the tendency order of oxidation reactivity was determined as follows: benzylic alcohols>aromatic allylic alcohols>>aliphatic alcohols. In addition, this method has several advantages, including a small amount of catalyst (0.5mol%) and selective application of high discrimination activity of aliphatic, aromatic allylic, and benzylic alcohols.

Recently I am researching about HONEYBUSH TEA; ASPALATHUS-LINEARIS; FLAVONOIDS; GENISTOIDES; SPP.; L.; MS, Saw an article supported by the National Research Foundation of South AfricaNational Research Foundation – South Africa [NR: 84442]; University of Johannesburg; Central Analytical Facility of Stellenbosch University.

As a contribution towards a better understanding of phenolic variation in the genus Cyclopia (honeybush tea), a collection of 82 samples from 15 of the 23 known species was analysed using liquid-chromatography-high resolution mass spectrometry (UPLC-HRMS) in electrospray ionization (ESI) negative mode. Mangiferin and isomangiferin were found to be the main compounds detected in most samples, with the exception of C. bowiena and C. buxifolia where none of these compounds were detected. These xanthones were found to be absent from the seeds and also illustrated consistent differences between species and provenances. Results for contemporary samples agreed closely with those based on analysis of a collection of ca. 30-year-old samples. The use of multivariate tools allowed for graphical visualizations of the patterns of variation as well as the levels of the main phenolic compounds. Exclusion of mangiferin and citric acid from the data was found to give better visual separation between species. The use of UPLC-HRMS generated a large dataset that allowed for comparisons between species, provenances and plant parts (leaves, pods, flowers and seeds). Phenetic analyses resulted in groupings of samples that were partly congruent with species but not with morphological groupings within the genus. Although different provenances of the same species were sometimes found to be very variable, Principle Component Analysis (PCA) indicated that a combination of compounds have some (albeit limited) potential as diagnostic characters at species level. 74 Phenolic compounds are presented, many of which were identified for the first time in Cyclopia species, with nine of these being responsible for the separation between samples in the PCAs.

A series of novel N’-(2-thiouracil-5-oyl)hydrazones were designed and chemically synthesized using an active substructure combination method. The synthesized compounds were structurally characterized on the basis of elemental (%) analyses, IR, MS, H-1 NMR, and C-13 NMR spectra. All the prepared compounds were evaluated in vitro against MCF-7 human breast cell line using MTT assay. The anticancer results showed that compounds 3j, 4a, 3c, 3b , and 3h exhibit the most prominent effect against breast cancer cell line with IC50 values of 3.40, 3.50, 3.60, 3.70, and 3.80 mu g/ml, respectively using doxorubicin as a control drug. Moreover, molecular docking studies were also performed in order to identify the binding mode mechanism of these compounds with prospective target, thymidylate synthase (PDB:1JU6). On the other hand, the antibacterial activities of all prepared compounds were screened in vitro against three bacterial strains, namely, Escherichia coli, and Pseudomonas aeruginosa as Gram negative bacteria and Staphylococcus aureus as a Gram positive bacterium using agar well diffusion method. The antibacterial activity results revealed that most of the compounds under test were inactive however, among all the tested compounds, only 3g and 4a , in a concentration of 50 mu g/ml showed a high antibacterial activity against the three used bacterial strained. It is worthy to note that the potency of 3g against Escherichia coli was comparable to that of the reference drug, while compound 2 exhibited significant activity against Pseudomonas aeruginosa only and compound 3j displayed low activity against Staphylococcus aureus. The structure-antibacterial activity relationship analysis can be modulated by the presence of aromatic or heteroaromatic moiety containing more lipophilic character significantly contributed to antibacterial activity. In addition, the drug-likeness properties have predicted for the target compounds. (C) 2021 Published by Elsevier B.V.

Efforts aimed at increasing the in vivo potency and reducing the elimination half-life of 1 and 2 led to the identification of aryl ether and thioether-derived bicyclic S1P(1) differentiated modulators 3-6. The effects of analogs 3-6 on lymphocyte reduction in the rat (desired pharmacology) along with pulmonary- and cardiovascular-related effects (undesired pharmacology) are described. Optimization of the overall properties in the aryl ether series yielded 3d, and the predicted margin of safety against the cardiovascular effects of 3d would be large enough for human studies. Importantly, compared to 1 and 2, compound 3d had a better profile in both potency (ED50 < 0.05 mg/kg) and predicted human half-life (t(1/2) similar to 5 days). COA of Formula: C7H8O2.

This paper describes the synthesis of polyindole by chemical oxidative polymerization using copper chloride as oxidant. Polyindole was characterized by various spectroscopic techniques like FT-IR, XRD, FESEM, and TGA. The XRD pattern confirms the semi-crystalline nature of polyindole. An efficient, solvent-free, ultrasound-assisted synthesis of biologically active 3,4-dihydropyrimidin-2(1 H)-one/thiones (DHPM) derivatives is reported by using polyindole as a recyclable catalyst. The advantages of this method are mild reaction conditions, short reaction time, excellent yields with high purity and low loading of catalyst. Polyindole can be used several times without loss of significant catalytic activity as compared to the other reported catalysts. Factors affecting on the rate of reaction, like use of ultrasonication, temperature, solvent, amount, and recyclability of catalyst have also been studied.
