A Cu-based homogeneous catalytic system was proposed for the preparation of imides from alkene-tethered amides. Here, O-2 acted as a terminal oxidant and a cheap and easily available oxygen source. The cleavage of C=C bonds and the formation of C-N bonds were catalyzed by Cu(ii) salts with proper nitrogen-containing ligands under 100 degrees C. The synthesis approach has potential applications in pharmaceutical syntheses. Moreover, scaled-up experiments confirmed the practical applicability.

Ethnopharmacological relevance: Danggui Buxue Tang (DBT) has been used to promote hematopoiesis and relieve myelosuppression in China. Antibiotics can cause myelosuppression through gut microbiota disorders. Aim of the study: This study aims to explore the way of DBT to alleviate the metabolic disorder caused by antibiotics. Materials and methods: In this study, 16S rRNA sequencing was used to detect the change of gut microbiota, metabolomics to analyze the change of metabolites. Correlation analysis was used to establishment the correlation between gut microbiota and metabolites. PICRUST 2 was used to predict the function of gut microbiota. Results: Results showed that eighty-two genera of gut microbiota were affected by antibiotic, while twelve were significantly restored after DBT. Seventy-four potential metabolites were significantly different from the antibiotics and DBT. We found significant recovery by the Bacteroides and Rikenellaceae RC9 after DBT. The metabolic pathways influenced by the antibiotic treatment included primary and secondary bile biosynthesis, etc. The metabolic pathways that could be restored after DBT included the primary and secondary bile acid biosynthesis pathway, etc. Through correlation analysis, we found a correlation between the Bacteroides, Rikenellaceae_RC9_gut_groupand other potential differential metabolisms such as those of taurodeoxycholic acid, N-phenylacetyl glycine, etc. The functional prediction showed that the biosynthesis of primary bile acid, secondary bile acid was significantly affected. Conclusions: DBT can restore the gut and reverse the metabolic disorder caused by antibiotics through Bacteroides, and it provides a new medical idea regarding the gut microbiota balance.

The majority of cytochrome P450 enzymes (CYPs) predominantly operate as monooxygenases, but recently a class of P450 enzymes was discovered, that can act as peroxygenases (CYP152). These enzymes convert fatty acids through oxidative decarboxylation, yielding terminal alkenes, and through alpha- and beta-hydroxylation to yield hydroxy-fatty acids. Bioderived olefins may serve as biofuels, and hence understanding the mechanism and substrate scope of this class of enzymes is important. In this work, we report on the substrate scope and catalytic promiscuity of CYP OleT(JE) and two of its orthologues from the CYP152 family, utilizing alpha-monosubstituted branched carboxylic acids. We identify alpha,beta-desaturation as an unexpected dominant pathway for CYP OleT(JE) with 2-methylbutyric acid. To rationalize product distributions arising from alpha/beta-hydroxylation, oxidative decarboxylation, and desaturation depending on the substrate’s structure and binding pattern, a computational study was performed based on an active site complex of CYP OleT(JE) containing the heme cofactor in the substrate binding pocket and 2-methylbutyric acid as substrate. It is shown that substrate positioning determines the accessibility of the oxidizing species (Compound I) to the substrate and hence the regio- and chemoselectivity of the reaction. Furthermore, the results show that, for 2-methylbutyric acid, alpha,beta-desaturation is favorable because of a rate-determining alpha-hydrogen atom abstraction, which cannot proceed to decarboxylation. Moreover, substrate hydroxylation is energetically impeded due to the tight shape and size of the substrate binding pocket.

Petal blight caused by fungi is among the most destructive diseases of Rhododendron, especially Rhododendron agastum. Nonetheless, the metabolite changes that occur during petal blight are unknown. We used untargeted gas chromatography time-of-flight mass spectrometry (GC-TOF-MS) and ultra-high performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry (UHPLC-QTOF-MS/MS) to compare the metabolite profiles of healthy and petal blight R. agastum flowers. Using GC-TOF-MS, 571 peaks were extracted, of which 189 metabolites were tentatively identified. On the other hand, 364 and 277 metabolites were tentatively identified in the positive and negative ionization modes of the UHPLC-QTOF-MS/MS, respectively. Principal component analysis (PCA) and orthogonal projections to latent structures-discriminant analysis (OPLS-DA) were able to clearly discriminate between healthy and petal blight flowers. Differentially abundant metabolites were primarily enriched in the biosynthesis of specialized metabolites. 17 accumulated specialized metabolites in petal blight flowers have been reported to have antifungal activity, and literature indicates that 9 of them are unique to plants. 3 metabolites (chlorogenic acid, medicarpin, and apigenin) are reportedly involved in resistance to blight caused by pathogens. We therefore speculate that the accumulation of chlorogenic acid, medicarpin, and apigenin may be involved in the resistance to petal blight. Our results suggest that these metabolites may be used as candidate biocontrol agents for the control fungal petal blight in Rhododendron.

A practical copper-catalyzed, 2-picolinamide-directed ortho C-H amination of anilines with benzoyl protected hydroxylamines has been disclosed that proceeds smoothly without any external stoichiometric oxidant or additives. Remarkably, besides anilines, bicyclic naphthyl or heterocyclic amines furnished amination products with five and six-membered cyclic and acyclic amines at the ortho position selectively. This electrophilic C-H amination also proceeds smoothly in water under slightly modified reaction conditions.

The 2-(neopentylsulfinyl)aniline directing group that promotes rapid palladium-catalyzed C-H acetoxylation and alkenylation of arylacetamides has been developed. The acetoxylation reaches completion within only 40 min at 100 degrees C and leads to the bis-functionalized products. Alternatively, the reaction can be carried out at room temperature, which is beneficial for sensitive substrates. For the alkenylation, we have developed a protocol in which easily available 1-substituted cyclopropanols were employed as equivalents of vinyl ketones.

A novel series of benzylidenethiazolidine-2,4-dione derivatives was synthesized and investigated for 15-hydroxyprostaglandin dehydrogenase (15-PGDH)-scavenging activity, PGE(2) release, and wound-healing activity. Among the tested derivatives, seven compounds (3, 9, 11, 12, 13, 14, and 25) resulted in a 50% inhibition of 15-PGDH at concentrations between 0.07 and 0.2 mu M and increased PGE(2) levels from 300 to over 600% in A549 cells treated with 5.0 and 10.0 mu M of the compounds for 12 h. A scratch wound-healing assay using HaCaT cell line was conducted to verify the effects of 10 mu M of these compounds on cell regeneration. The closure rate of the scratch wound healing showed that all compounds (3, 9, 11, 12, 13, 14, and 25) had greater wound regeneration effects than the cell growth factor, TGF-beta 1, which was used as the positive control. In particular, (Z)-N-benzyl-4-((2,4-dioxothiazolidin-5-ylidene)methyl)benzamide (compound 14) showed that the highest wound closure rate, which was 360%; this is about 3.6-fold higher than that of TGF-beta 1. Overall, these results show that compound 14 may be considered a promising candidate for the development of novel wound-healing agents.

Olefins are prevalent substrates and functionalities. The synthesis of olefins from readily available starting materials such as alcohols, amines and carboxylic acids is of great significance to address the sustainability concerns in organic synthesis. Metallaphotoredox-catalyzed defunctionalizations were reported to achieve such transformations under mild conditions. However, all these valuable strategies require a transition metal catalyst, a ligand or an expensive photocatalyst, with the challenges of controlling the region- and stereoselectivities remaining. Herein, we present a fundamentally distinct strategy enabled by electron donor-acceptor (EDA) complexes, for the selective synthesis of olefins from these simple and easily available starting materials. The conversions took place via photoactivation of the EDA complexes of the activated substrates with alkali salts, followed by hydrogen atom elimination from in situ generated alkyl radicals. This method is operationally simple and straightforward and free of photocatalysts and transition-metals, and shows high regio- and stereoselectivities.

Bambusa pervariabilis x Dendrocalamopsis grandis blight, caused by Arthrinium phaeospermum, is one of the most common and serious diseases in bamboo and occurs in the newly born twigs. Bamboo has suffered large dead areas, including more than 3000 hm(2), which greatly threatens the process of returning farmlands to forests and the construction of ecological barriers. To identify differential metabolites and metabolic pathways associated with B. pervariabilis x D. grandis to A. phaeospermum, ultra-performance liquid chromatography (UPLC) and quadrupole-time of flight (Q-TOF) Mass Spectrometry (MS) combined with a data-dependent acquisition method was used to analyse the entire sample spectrum. In total, 13223 positive ion peaks and 10616 negative ion peaks were extracted. OPLS-DA and several other analyses were performed using the original data. The OPLS-DA models showed good quality and had strong predictive power, indicating clear trends in the analyses of the treatment and control groups. Clustering and KEGG pathway analyses were used to screen the differential metabolites in the treatment and control groups from the three B. pervariabilis X D. grandis varieties and reflected their metabolic responses induced by A. phaeospermum infection. The results showed that the three B. pervariabilis x D. grandis varieties mode showed significant changes in the following six resistance-related metabolites after A. phaeospermum invasion in positive and negative ion modes: proline, glutamine, dictamnine, apigenin 7-O-neohesperidoside, glutamate, and cis-Aconitate. The following four main metabolic pathways are involved: Arginine and proline metabolism, Glyoxylate and dicarboxylate metabolism, Biosynthesis of alkaloids derived from shikimate pathway, and Flavone and flavonol biosynthesis. This study lays a foundation for the later detection of differential metabolites and metabolic pathways for targeting, and provides a theoretical basis for disease-resistant breeding and the control of B. pervariabilis x D. grandis blight.
