Keerthisinghe, Tharushi Prabha published the artcileFeeding state greatly modulates the effect of xenobiotics on gut microbiome metabolism: A case study of tetracycline, SDS of cas: 104-01-8, the main research area is tetracycline microbiome metabolism xenobiotic feeding state greatly modulate; Fasted state; Fed state; Global metabolomics; Gut microbiome; Tetracycline.

The human gut microbiome is crucial in modulating host health mostly through bacterial metabolites. Chem. exposure is typical external stress which alters its composition and functionality. To date, very few studies have investigated the effect of feeding state on chem.-induced gut microbial metabolic dysregulations. Here, we set up an in vitro human gut microbiome and incorporated a metabolomics approach to investigate the effect of tetracycline (TET) at multiple doses (i.e., 10, 1, and 0.01 mg/L) on gut microbiome under the fed and fasted states. Overall, the metabolome was highly responsive at the fed state with 62 metabolites dysregulated while only 14 were altered at the fasted state under 10 mg/L (clin. TET dose). As expected, nutrient consumption was significantly inhibited under clin. TET dose at the fed state accumulating nutrients such as glutamate and leucine. Interestingly, at the fed state, TET could increase the synthesis of indole and Ph derivatives including indole-3-aldehyde and hydrocinnamate, while inhibiting indoxyl, tryptamine, and vitamin B production, all of which have host health implications. Furthermore, metabolites like indoxyl and xanthurenic acid were still responsive at 0.01 mg/L (dietary TET dose). Collectively, results demonstrated that the feeding state greatly modulates the chem.-induced gut microbial metabolic alterations.

Habert, Loic published the artcilePhotoinduced Aerobic Iodoarene-Catalyzed Spirocyclization of N-Oxy-amides to N-Fused Spirolactams, Computed Properties of 104-01-8, the main research area is oxyamide fused spirolactam preparation photoinduced aerobic iodoarene catalyst spirocyclization; aerobic photoredox reaction; dual organocatalysis; hypervalent iodine; pyrylium.

Iodoarene catalysis is a powerful methodol. that usually requires an excess of oxidant, or of redox mediator if the terminal oxidant is dioxygen, to generate the key hypervalent iodine intermediate to proceed efficiently. The authors report that, using the spiro-cyclization of amides as a benchmark reaction, aerobic iodoarene catalysis can be enabled by relying on a pyrylium photocatalyst under blue light irradiation This unprecedented dual organocatalytic system allows the use of low catalytic loading of both catalysts under very mild operating conditions.

Cai, Mengke published the artcileEvaluation of antimicrobial activity of Pterocarpus extracts, Application In Synthesis of 104-01-8, the main research area is Pterocarpus Populus Coriolus Gloeophyllum extract antimicrobial.

Pterocarpus is one of the most widely used timber resources on the market. But the utilization rate has been low. In order to improve the utilization of Pterocarpus processing residue, as well as explore the reason of its good decay-resistance. In this study, the antifungal mechanism of Peterocarpes spp., aqueous extracts and ethanol extracts of three Pterocarpus species were studied. The antimicrobial active factors were analyzed by gas chromatog.-mass spectrometry. Italian poplar (Populus euramevicana cv. I-214) wood was immersed in the extracts and then inoculated with both Coriolus versicolor and Gloeophyllum trabeum. The antimicrobial properties of the extracts were studied, and the mechanism underlying these properties were analyzed using gas chromatog.-mass spectrometry. The results showed that the yield of ethanol extracts from the three Pterocarpus species was significantly higher than that of aqueous extracts Pterocarpus soyauxii and Pterocarpus macarocarpus produced the highest yield of ethanol extracts (28.59%) and aqueous extracts (14.31%), resp. With increasing concentrations, the antimicrobial activities of aqueous extracts of Pterocarpus angolensis and Pterocarpus macarocarpus gradually increased, while the antimicrobial activity of other extracts remained constant Gas chromatog.-mass spectrometry anal. identified a considerable number of phenols, ketones, amines, and aromatic compounds in all extracts, which is consistent with their antimicrobial activity and suggests synergism among the chems.

Chemoselective catalytic activation of carboxylic acid for a 1e- radical process is described. The α-oxidation of a variety of carboxylic acids HOC(O)CH2R (R = 4-methylphenyl, 2H-1,3-benzodioxol-5-yl, thiophen-3-yl, etc.), which preferentially undergo undesired decarboxylation under radical conditions, proceeded efficiently under the optimized conditions. Chemoselective enolization of carboxylic acid was also achieved even in the presence of more acidic carbonyls. Extensive mechanistic studies revealed that the cooperative actions of iron species and alkali metal ions derived from 4 Å mol. sieves substantially facilitated the enolization. For the first time, catalytic enolization of unprotected carboxylic acid was achieved without external addition of stoichiometric amounts of Bronsted base.
