Serotonergic psychedelics, substances exerting their pharmacological action through activation of the serotonin 2A receptor (5-HT2AR), have continuously comprised a substantial fraction of the over 1000 reported New Psychoactive Substances (NPS) so far. Within this category, N-benzyl derived phenethylamines, such as NBOMes and NBFs, have shown to be of particular relevance. As these substances remain incompletely characterized, this study aimed at synthesizing positional isomers of 25H-NBF, with two methoxy groups placed on different positions of the phenyl group of the phenethylamine moiety. These isomers were then functionally characterized in an in vitro bioassay monitoring the recruitment of beta-arrestin 2 to the 5HT(2A)R through luminescent readout via the NanoBiT technology. The obtained results provide insight into the optimal substitution pattern of the phenyl group of the phenethylamine moiety of N-benzyl derived substances, a feature so far mostly explored in the phenethylamines underived at the N-position. In the employed bioassay, the most potent substances were 24H-NBF (EC50 value of 158 nM), 26H-NBF (397 nM), and 25H-NBF (448 nM), with 23H-NBF, 35H-NBF, and 34H-NBF yielding mu M EC50 values. A similar ranking was obtained for the compounds’ efficacy: taking as a reference LSD (lysergic acid diethylamide), 24H-, 26H-, and 25H-NBF had an efficacy of 106-107%, followed by 23H-NBF (96.1%), 34H-NBF (75.2%), and 35H-NBF (58.9%). The stronger activity of 24H-, 25H-, and 26H-NBF emphasizes the important role of the methoxy group at position 2 of the phenethylamine moiety for the in vitro functionality of NBF substances.

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.

Application In Synthesis of 3-(Trifluoromethyl)phenol. I found the field of Chemistry very interesting. Saw the article Sequential Energy Transfer Catalysis: A Cascade Synthesis of Angularly-Fused Dihydrocoumarins published in 2019, Reprint Addresses Gilmour, R (corresponding author), Westfalische Wilhelms Univ Munster, Inst Organ Chem, Corrensstr 40, D-48149 Munster, Germany.. The CAS is 98-17-9. Through research, I have a further understanding and discovery of 3-(Trifluoromethyl)phenol.

An operationally simple one-pot protocol has been developed to enable the conversion of diversely substituted cinnamic acid derivatives into angularly-fused dihydrocoumarins (up to 94%). Inspired by coumarin biosynthesis, this reaction cascade harnesses photochemical E -> Z alkene isomerization enabled by energy transfer catalysis using inexpensive thioxanthen-9-one (TX) under irradiation at 402 nm. Subsequent lactonization generates the heterocyclic core prior to a second photosensitization event to induce a [2 + 2] cycloaddition, again mediated by TX. The tetracyclic products are generated efficiently, and proof of the structure was established by X-ray crystallography. Mechanistic investigations, including structural probes and NMR reaction monitoring, support the postulated order of events. The study underscores the synthetic value of inexpensive small-molecule organic photocatalysts in the generation of structural complexity via sequential pi-bond activation.

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.

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.

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.

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.
