Determination of indole-type phytonutrients in cruciferous vegetables

Consumption of cruciferous vegetables has been associated with a low risk of developing cancer. Indole-type phytonutrients, derived from enzymatic hydrolysis of glucobrassicin, exhibit cancer-preventive properties and occur in all vegetables of theBrassicaceaefamily. A LC-Q-TOF-MS methodology was developed and applied in extracts from seven cruciferous vegetables allowing the rapid determination of indole-3-carbinol, indole-3-carbaldehyde, ascorbigen, indole-3-acetic acid and indole-3-acetonitrile.

Ring-opening transformations of donor-acceptor cyclopropanes (DAC) with carbon-centered nucleophiles is a simple, straight-forward approach to 1,3-bifunctional compounds that has witnessed remarkable progress over the past several years. To date, different reactivity patterns of DACs have been successfully exploited in racemic/stereoselective syntheses of various acyclic compounds or carbocycles with an impressive structural diversity. The thriving strategies have been successfully utilized in multistep synthesis of complex target molecules. Herein, the recent advances (2015-present) in the ring-opening of DAC involving electron rich arenes and indoles, active methylene compounds, various dipolarophiles, organoborates/boronates, vinyl ethers etc. following Friedel-Crafts alkylation, annulation/formal cycloaddition reaction, organocatalytic reaction, Nazarov cyclisation etc. are presented.

Synthesis of Indoles via Electron-Catalyzed Intramolecular C-N Bond Formation

A new protocol for the preparation of N-substituted indole-3-carboxylates has been developed. The key C-N bond formation occurs under transition-metal-free conditions employing a t-BuOK/DMF system without special initiators or additives. Across a number of substrates, indoles were afforded in yields higher or comparable to those obtained under transition-metal catalyzed conditions. While demonstrating high functional group tolerance, new conditions are particularly attractive for manufacturing halogenated indoles that cannot be made in a pure form using other metal-based catalytic methods.

Characterization of the TyrR Regulon in the Rhizobacterium Enterobacter ludwigii UW5 Reveals Overlap with the CpxR Envelope Stress Response

The TyrR transcription factor controls the expression of genes for the uptake and biosynthesis of aromatic amino acids in Escherichia coli. In the plant associated and clinically significant proteobacterium Enterobacter ludwigii UW5, the TyrR orthologue was previously shown to regulate genes that encode enzymes for synthesis of the plant hormone indole-3-acetic acid and for gluconeogenesis, indicating a broader function for the transcription factor. This study aimed to delineate the TyrR regulon of E. ludwigii by comparing the transcriptomes of the wild type and a tyrR deletion strain. In E. ludwigii, TyrR positively or negatively regulates the expression of over 150 genes. TyrR downregulated expression of envelope stress response regulators CpxR and CpxP through interaction with a DNA binding site in the intergenic region between divergently transcribed cpxP and cpxR. Repression of cpxP was alleviated by tyrosine. Methyltransferase gene dmpM, which is possibly involved in antibiotic synthesis, was strongly activated in the presence of tyrosine and phenylalanine by TyrR binding to its promoter region. TyrR also regulated expression of genes for aromatic catabolism and anaerobic respiration. Our findings suggest that the E. ludwigii TyrR regulon has diverged from that of E. coli to include genes for survival in the diverse environments that this bacterium inhabits and illustrate the expansion and plasticity of transcription factor regulons. IMPORTANCE Genome-wide RNA sequencing revealed a broader regulatory role for the TyrR transcription factor in the ecologically versatile bacterium Enterobacter ludwigii beyond that of aromatic amino acid synthesis and transport that constitute the role of the TyrR regulon of E. coli. In E. ludwigii, a plant symbiont and human gut commensal, the TyrR regulon is expanded to include genes that are beneficial for plant interactions and response to stresses. Identification of the genes regulated by TyrR provides insight into the mechanisms by which the bacterium adapts to its environment.

Chromosome-level genome assembly of Ophiorrhiza pumila reveals the evolution of camptothecin biosynthesis

Plant genomes remain highly fragmented and are often characterized by hundreds to thousands of assembly gaps. Here, we report chromosome-level reference and phased genome assembly of Ophiorrhiza pumila, a camptothecin-producing medicinal plant, through an ordered multi-scaffolding and experimental validation approach. With 21 assembly gaps and a contig N50 of 18.49Mb, Ophiorrhiza genome is one of the most complete plant genomes assembled to date. We also report 273 nitrogen-containing metabolites, including diverse monoterpene indole alkaloids (MIAs). A comparative genomics approach identifies strictosidine biogenesis as the origin of MIA evolution. The emergence of strictosidine biosynthesis-catalyzing enzymes precede downstream enzymes’ evolution post gamma whole-genome triplication, which occurred approximately 110 Mya in O. pumila, and before the whole-genome duplication in Camptotheca acuminata identified here. Combining comparative genome analysis, multi-omics analysis, and metabolic gene-cluster analysis, we propose a working model for MIA evolution, and a pangenome for MIA biosynthesis, which will help in establishing a sustainable supply of camptothecin.Ophiorrhiza pumila is a medicinal plant that can produce the anti-cancer monoterpene indole alkaloid (MIA) camptothecin. Here, the authors report its genome assembly and propose a working model for MIA evolution and biosynthesis through comparative genomics, synteny, and metabolic gene cluster analyses.

Gender differences in plasma pharmacokinetics and hepatic metabolism of geissoschizine methyl ether from Uncaria hook in rats

Ethnopharmacological relevance: Geissoschizine methyl ether (GM), an indole alkaloid from Uncaria hook, is an active ingredient in the traditional Japanese Kampo medicine yokukansan, which is used to treat neurosis, insomnia, irritability, and night crying in children. Aim of the study: Recent our pharmacokinetic studies suggested that there may be gender differences in the plasma concentrations of GM in rats, but not in humans. However, the details of this difference remain unverified. The purpose of this study was to clarify the reasons for the gender differences in rats. Materials and methods: GM plasma pharmacokinetics was compared in male and female rats orally administered yokukansan (4 g/kg). To confirm the involvement of cytochrome P450 (CYP) in GM liver metabolism, GM was incubated with male and female rat liver 59 fraction in the absence or presence of 1-aminobenzotriazole (a nonspecific CYP inhibitor). CYP isoforms involved in GM metabolism were estimated using recombinant rat CYP isoforms and anti-rat CYP antibodies. Results: The maximum GM plasma concentrations were significantly higher in female than in male rats. When GM was incubated with rat liver 59 fractions, GM reduction was more striking in male 59 (69.3%) than that in female 59 (10.0%) and was completely blocked with nonspecific CYP inhibitor 1-aminobenzotriazole. Screening experiments using recombinant rat cytochmme P450 (CYP) isoforms showed that CYP1A1, CYP2C6, CYP2C11, CYP2D1, and CYP3A2 were involved in GM metabolism. Of these CYP isoforms, the use of anti-rat CYP antibodies indicated that male-dependent CYP2C11 and CYP3A2 were predominantly involved in the liver micro-somal GM metabolism with gender differences. Conclusions: These results suggest that the cause of gender differences in plasma GM pharmacokinetics in rats is most likely because of male-dependent CYP2C11 and CYP3A2, and provide also useful information to further evaluate the pharmacological and toxicological effects in future. This study is the first to demonstrate that the gender differences in plasma GM pharmacokinetics in rats are caused by the gender-dependent metabolism of GM.
