Indolic Derivatives Metabolism in the Anaerobic Reactor Treating Animal Manure: Pathways and Regulation

The positive effect of anaerobic digestate on plant growth is attributed not only to the macronutrients it contains (e.g., nitrogen and phosphorus) but also to its high level of indole-3-acetic acid (IAA), which is one of the important plant hormones. Results of indolic derivative analysis in anaerobic reactors revealed that IAA was produced from L-tryptophan. Results of experiments using single indolic component showed that L-tryptophan metabolism under alkalescent anaerobic condition follows two pathways. (i) L-Tryptophan can be converted into skatole via IAA (ISP), and exogenous carbon can completely inhibite the process from IAA to skatole, in which IAA production is enhanced. (ii) Simultaneously, L-tryptophan can also be directly converted into indole (IPM). The mineralization of indole was enhanced by synergetic effect of L-tryptophan and other amino acids. Based on these findings, carbon source and amino acids can theoretically regulate IAA production and indole mineralization, respectively. These findings provide some new perspectives on IAA regulation and indole decontamination in liquid digestate.

Selective Synthesis of Pyrano[3,2-b]indoles or Cyclopenta[b]indoles Tethered with Medium-Sized Rings via Cascade C-C sigma-Bond Cleavage and C-H Functionalization

Highly atom-economical tandem reactions have been developed for the synthesis of pyrano[3,2-b]indoles or cyclopenta[b]indoles tethered with 7-, 8-, or 9-membered rings. These reactions first undergo a carbon-carbon sigma-bond cleavage reaction of cyclic beta-ketoesters. Next, in the presence of CuCl2 and Ag2CO3, intramolecular O-H/C-H coupling occurs to give pyrano[3,2-b]indoles. This is the first example for capture of the enoloxyl radical of the intramolecular C-O bond formation reaction, whereas C3 nucleophilic addition afforded cyclopenta[b]indoles using TsOH center dot H2O.

A Study on the Interaction between New Indole Amide Compound and Aluminum(III) Ion

A new indole-based compound N-(pyridine-2-ylmethyl)-1H-indole-2-carboxamide (FL) which could selectively recognize Al3+ had been designed, synthesized and evaluated. FL could detect Al3+ with high sensitivity. The fluorescence intensity of FL-Al3+ solution was linear dependence to the concentration of Al3+ in the ranges from 0 to 5 mol/L. The addition of Al3+ caused quenching of fluorescence intensity and the limit of detection for Al3+ was as low as 1.79×10(-9)M. The binding ratio of FL-Al3+ was obtained 3:2 by Job’s plot and the binding constant was 9.37×10(5). Moreover, FL had been successfully applied in real sample detection.

Hydrogen-bonded polyamide 6/Zr-MOF mixed matrix membranes for efficient natural gas dehydration

New types of mixed matrix membranes (MMMs) were fabricated by incorporating Zr-MOF (UiO-66-NH2 and UiO66-NH3+Cl-) filler into polyamide 6 (PA 6) polymer, enabling efficient natural gas dehydration. All membranes were characterized and applied for H2O/CH4 mixtures separation at 1 bar pressure difference at 30 degrees C. It was found that the Zr-MOF nanoparticles in a size range of 0.4-0.5 mu m were successfully incorporated into the high permeability polymer PA 6 to obtain MMMs with 10-30 wt% particle loadings. MMMs loaded with 25 wt% of UiO-66-NH3+Cl- and 20 wt% of UiO-66-NH2 demonstrated ultrahigh H2O/CH4 selectivity of 747.7 and 687.4, respectively, and enhanced H2O permeability as well as H2O/CH4 selectivity compared with the pure PA 6 polymer. The excellent membrane performance attributed to direct and extensive hydrogen bonds between the polymer and MOFs. This type of MMMs could be an alternative for further research in H2O/CH4 separation at industrial scale.

Identification and characterization of CTP:phosphocholine cytidylyltransferase CpCCT1 in the resurrection plant Craterostigma plantagineum

Phosphatidylcholine is a major phospholipid which is shown to be involved in stress adaptation. Phosphatidylcholine increased during dehydration in Craterostigma plantagineum, and therefore we characterized CTP: phosphocholine cytidylyltransferase (CpCCT1), a key regulatory enzyme for phosphatidylcholine synthesis in plants. The CpCCT1 gene from the resurrection plant C. plantagineum was cloned and the amino acid sequence was compared with homologs from other species including yeast and rat. CCT proteins have conserved catalytic and membrane-binding domains while the N-terminal and C-terminal domains have diverged. The tissue specific expression analysis indicated that CpCCT1 is expressed in all tested tissues and it is induced by dehydration and in response to 0.5 M NaCl solutions. In plants exposed to low temperature in the dark, the CpCCT1 transcript increased after 4 h at 4 degrees C. CpCCT1 expression also increased during mannitol and sorbitol treatments in a concentration dependent manner. Phytohormones such as abscisic acid and indole-3-acetic acid also trigged transcript accumulation. Comparisons of transcript and protein accumulations for different treatments (except for dehydration) suggest transcriptional and translational control mechanisms. Analysis of promoter activity and polysome occupancy suggest that CpCCT1 gene expression is mainly under translational regulation during dehydration.

Cyclic bridged analogs of isoCA-4: Design, synthesis and biological evaluation

In this work, a series of cyclic bridged analogs of isocombretastatin A-4 (isoCA-4) with phenyl or pyridine linkers were designed and synthesized. The synthesis of the desired analogs was performed by the formation of nitro-vinyl intermediates, followed by a Cadogan cyclization. Structure activity relationship (SAR) study demonstrates the critical role of the combination of quinaldine as ring A, pyridine as the linker, and indole as ring B in the same molecule, for the cytotoxic activity. Among all tested compounds, compound 42 showed the highest antiproliferative activity against a panel of cancer cell lines with average IC50 values of 5.6 nM. Also, compound 42 showed high antiproliferative activity against the MDR1-overexpressing K562R cell line; thus, it was 1.5- and 12-fold more active than the reference compounds, isoCA-4 and CA-4, respectively. Moreover, 42 displayed a strong antiproliferative activity against the colon-carcinoma cells (HT-29), which are resistant to combretastatin A-4 and isoCA-4, and it was found to be 8000-fold more active than natural CA-4. Compound 42 also effectively inhibited tubulin polymerization both in vitro and in cells, and induced cell cycle arrest in G2/M phase. Next, we demonstrated that compound 42 dose-dependently caused caspase-induced apoptosis of K562 cells through mitochondrial dysfunction. Finally, we evaluated the effect of compound 42 in human no cancer cells compared to the reference compound. We demonstrated that 42 was 73 times less cytotoxic than isoCA-4 in quiescent peripheral blood lymphocytes (PBLs). In summary, these results suggest that compound 42 represents a promising tubulin inhibitor worthy of further investigation. (c) 2020 Elsevier Masson SAS. All rights reserved.

When Indoles Meet Allene and its Derivatives

The allene functional group and the indole ring have emerged as recurring building blocks in organic chemistry due to their diverse reactivity and straightforward preparation. In addition, the biological properties and natural occurrence of indole give a remarkable added-value to newly-prepared indole-based structures. In the last decade, the combination of allenes and indoles as co-reactants has revealed a fruitful reactivity allowing the synthesis of complex structures and the investigation of new mechanistic pathways, such as the challenging asymmetric nucleophilic addition using optically pure allenes as chirality transfer agents, the double nucleophilic addition through metal carbene intermediates, or novel hybrid catalysis in a bimetallic system. Herein we report a critical review into the wide and fascinating ways allenes and indoles can interact, and the structural diversity that can be therefore achieved.

Palladium-Catalyzed Silacyclization of (Hetero)Arenes with a Tetrasilane Reagent through Twofold C-H Activation

The use of an operationally convenient and stable silicon reagent (octamethyl-1,4-dioxacyclohexasilane, ODCS) for the selective silacyclization of (hetero)arenes via twofold C-H activation is reported. This method is compatible with N-containing heteroarenes such as indoles and carbazoles of varying complexity. The ODCS reagent can also be utilized for silacyclization of other types of substrates, including tertiary phosphines and aryl halides. A series of mechanistic experiments and density functional theory (DFT) calculations were used to investigate the preferred pathway for this twofold C-H activation process.
