Arylation of indoles using cyclohexanones dually-catalyzed by niobic acid and palladium-on-carbons

3-Arylindoles were easily constructed from indoles and cyclohexanone derivatives using a combination of catalytic niobic acid-on-carbon (Nb2O5/C) and palladium-on-carbon (Pd/C) under heating conditions without any oxidants. The Lewis acidic Nb2O5/C promoted the nucleophilic addition of indoles to the cyclohexanones, and the subsequent dehydration and Pd/C-catalyzed dehydrogenation produced the 3-arylindoles. The additive 2,3-dimethyl-1,3-butadiene worked as a hydrogen acceptor to facilitate the dehydrogenation step.

Detosylative (Deutero)alkylation of Indoles and Phenols with (Deutero)alkoxides

An efficient strategy for N/O-(deutero)alkylation of indoles and phenols with alkoxides/alcohols as the alkylation reagents is described. The consecutive detosylation/alkylation transformations feature mild reaction conditions, high ipso-selectivity, and good functional group tolerance (>50 examples). A one-pot selective N-alkylation of unprotected indoles with alcohols and TsCl is also realized. The application of this method is demonstrated by the introduction of isotope-labeled (CD3 and (CH3)-C-13) groups using the readily accessible labeled alcohols and the synthesis of pharmaceuticals.

Sulfinate and Carbene Co-catalyzed Rauhut-Currier Reaction for Enantioselective Access to Azepino[1,2-a]indoles

A carbene and sulfinate co-catalyzed intermolecular Rauhut-Currier reaction between enals and nitrovinyl indoles is disclosed. The carbene catalyst activates the enal and the sulfinate co-catalyst activates the nitrovinyl indole. Both activation processes are realized via the formation of covalent bonds between the catalysts and substrates to generate catalyst-bound intermediates. The dual catalytic reaction affords azepino[1,2-a]indole products with excellent stereoselectivity. Our study demonstrates the unique involvement of sulfinate as an effective nucleophilic catalyst in activating electron-deficient alkenes for asymmetric reactions. This dual catalytic approach should also encourage future explorations of both sulfinate and carbene catalysts for new reactions.

A Study of the Reactivity of (Aza-)Quinone Methides in Selective C6-Alkylations of Indoles

The kinetic and thermodynamic features of indole N1- and C6-alkylation reactions with (aza-)quinone methides have been studied. The electrophilic reactivity of these quinone methides have also been compared for the first time by both experiments and DFT calculations. The indole N1-alkylation is typically kinetically favorable, but the C6-alkylation is more thermodynamically favorable. With suitable conditions, the C6-alkylation could be achieved with high efficiency and selectivity. Among these quinone methides, the reactivity increases from aza-p-QMs to o-QMs. The results not only provide access to a range of valuable triarylmethanes, but also guide future development of new reactions with these versatile electrophiles.

Structure-based linker exploration: Discovery of 1-ethyl-1H-indole analogs as novel ATX inhibitors

Aiming to develop novel ATX inhibitors, an indole-3-carboxylic acid lead Indole-1 was identified through high-throughput screening (HTS) efforts. The Indole-1 analogs 1-7 was firstly prepared which exerted mild activity comparable to Indole-1 (740 nM) in ATX enzyme assay. Further structural modification to identify type IV ATX inhibitors was proceeded through derivatization of the indole-3-carboxylic acid group. Resultantly, compounds 8-17 containing acyl hydrazone linker displayed poor activity (over 3.49 mu M). Alternatively, replacing the acylhydrazone linker with urea counterpart by the amide bond reversal principle, the acquired compounds 18-22 achieved obvious improvements with submicromolar activities. Furthermore, with the aim to reducing cLogP, the thiazole ring of 18-22 was altered to the benzamide (23-32) with the urea linker unchanged. Remarkably, the benzamide derivative 24 with 4-hydroxy piperidine fragment was identified which exhibited prominent activity with IC50 value of 2.3 nM. Especially, dedicated molecular docking study was throughout the modification process which qualified 24 as optimal entity in accordance with the ATX inhibitory results.

Bacteroides thetaiotaomicron relieves colon inflammation by activating aryl hydrocarbon receptor and modulating CD4(+)T cell homeostasis

Inflammatory bowel disease (IBD) is a form of nonspecific chronic intestinal inflammation associated with gut microbiome dysbiosis. Modulating the composition of the intestinal flora may be a viable means of alleviating such inflammatory pathology. Bacteroides thetaiotaomicron (B. thetaiotaomicron) is a symbiotic intestinal microbe that has been associated with IBD, although the mechanistic basis for this association remains to be clarified. In this present study, we determined that B. thetaiotaomicron can alleviate colonic inflammation through mechanisms associated with the modulation of tryptophan metabolism and T cell subsets within inflamed intestinal tissues. Specifically, we found that B. thetaiotaomicron promotes the preferential differentiation of antiinflammatory Treg/Th2 cells while suppressing the relative differentiation of pro-inflammatory Th1/Th17 cells, thereby decreasing inflammation within the colon. At a molecular level, B. thetaiotaomicron treatment was linked to altered CpG methylation within the Foxp3 promoter that was associated with enhanced Treg cell functionality. In a murine dextran sulfate sodium (DSS) colitis model system, B. thetaiotaomicron increased the levels of the aryl hydrocarbon receptor (AHR) ligands indole metabolites-indole acetic acid (IAA) and indole propionic acid (IPA), thereby increasing AHR activation that is related to changes of transcription factor expression profiles within T cells. In summary, our data suggest that B. thetaiotaomicron can activate AHR and modulate CD4(+) T cell differentiation profiles in a murine DSS colitis model system, suggesting that this bacterium may be of therapeutic relevance for the treatment of IBD.yy

Recurrent secondary embryogenesis in androgenic embryos and clonal fidelity assessment of haploid plants of Tea,Camellia assamica ssp. assamica and Camellia assamica ssp. lasiocaylx

Globular androgenic haploid embryos of TV21 and TV19 cultivars of Camellia ssp., obtained on embryo induction medium (EIM), Murashige and Skoog medium with 10 mu M 6-benzylaminopurine (BAP), 3 mu M gibberellic acid (GA(3)), 800 mg l(-1) L-glutamine and 200 mg l(-1) L-serine, were pretreated with 18 mu M abscisic acid (ABA) and 25 g l(-1) mannitol for 20 days in liquid medium to attain maturation. The pre-treatment favoured the primary globular embryos to grow and pass through all the developmental stages from globular, heart-shape, torpedo shape to fully matured docotyledonous embryos. Fivefold and threefold increase in secondary embryogenesis (SE) was attained in Camellia assamica ssp. assamica (TV21; Assam Type) and Camellia assamica ssp. lasiocaylx (TV19; Cambod Type), respectively, when pre-treated primary embryos were transferred to the liquid embryo development (ED) medium, supplemented with tenfold reduced concentration of growth regulators that were present in EIM. Embryos were germinated well on 10 mu M BAP, 0.5 mu M GA(3), 1 mu M indole-3-butyric acid (IBA), 80 mg l(-1) L-glutamine and 20 mgl(-1) L-serine, following liquid-to-semi-solid transition method. Well developed shoots and roots were formed when embryos were initially kept for four weeks in liquid germination medium, followed by their transfer to semi-solid medium on similar medium composition. The method promoted recurrent secondary embryogenesis in lesser time with highest germination rate, 66.6% and 30.3% in TV21 and TV19 cultivars, respectively. Histology and field emission scanning electron microscopy (FESEM) were performed to determine ontological events during embryo development. Clonal fidelity of haploid plantlets was assessed using random amplified polymorphic DNA (RAPD) to ensure no somaclonal variations occurred during the multistep process of secondary embryogenesis, embryo maturation and germination.

Optimization of theoretical maximal quantity of cells to immobilize on solid supports in the rational design of immobilized derivatives strategy

Current worldwide challenges are to increase the food production and decrease the environmental contamination by industrial emissions. For this, bacteria can produce plant growth promoter phytohormones and mediate the bioremediation of sewage by heavy metals removal. We developed a Rational Design of Immobilized Derivatives (RDID) strategy, applicable for protein, spore and cell immobilization and implemented in the RDID1.0 software. In this work, we propose new algorithms to optimize the theoretical maximal quantity of cells to immobilize (tMQ(Cell)) on solid supports, implemented in the RDIDCell software. The main modifications to the preexisting algorithms are related to the sphere packing theory and exclusive immobilization on the support surface. We experimentally validated the new tMQ(Cell) parameter by electrostatic immobilization of ten microbial strains on AMBERJET((R)) 4200 Cl- porous solid support. All predicted tMQ(Cell) match the practical maximal quantity of cells to immobilize with a 10% confidence. The values predicted by the RDIDCell software are more accurate than the values predicted by the RDID1.0 software. 3-indolacetic acid (IAA) production by one bacterial immobilized derivative was higher (similar to 2.6 mu g IAA-like indoles/10(8) cells) than that of the cell suspension (1.5 mu g IAA-like indoles/10(8) cells), and higher than the tryptophan amount added as indole precursor. Another bacterial immobilized derivative was more active (22 mu g Cr(III)/10(8) cells) than the resuspended cells (14.5 mu g Cr(III)/10(8) cells) in bioconversion of Cr(VI) to Cr(III). Optimized RDID strategy can be used to synthesize bacterial immobilized derivatives with useful biotechnological applications.
