Pantoea agglomerans YS19 poly(A) polymerase I gene possesses the indole-sensing sequence in the promoter region

Pantoea agglomerans YS19 is a predominant diazotrophic endophyte with multiple growth-promoting effects on its host plant that was isolated from rice. Indole is confirmed to induce many changes of physiological and biochemical characteristics in bacteria. Although YS19 cannot produce indole, it can sense indole in the environment and be regulated by indole. Here, using gfp as a reporter gene, we constructed a series of recombinant plasmids containing the promoter region of the poly(A) polymerase I gene (pcnB) fusedwith gfp, and compared the green fluorescence intensity at different concentrations of exogenous indole by a flow cytometer. In this research, we confirmed that exogenous indole significantly inhibited the expression of pcnB by its promoter; the regulation sequence sensitive to indole in the promoter region of the pcnB gene (In-pcnB) was between -129 and -88 bp. In-pcnB is widely distributed and strictly conserved in the same genus. These results suggest novel roles of In-pcnB in P. agglomerans YS19, showing its special relation to the indole regulatory pathway.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 28721-07-5 help many people in the next few years. Formula: C15H12N2O2.

Effects of indole and indoxyl on the intracellular oxidation level and phagocytic activity of differentiated HL-60 human macrophage cells

Indoxyl, a derivative of indole originating from tryptophan, may undergo phase-II sulfate-conjugation pathway, thereby forming indoxyl sulfate (IS) in vivo. We previously reported that IS, a well-known uremic toxin, can increase the intracellular oxidation level and decrease the phagocytic activity in a differentiated HL-60 human macrophage cell model. Using the same cell model, the current study aimed to investigate whether indole and indoxyl (the metabolic precursors of indoxyl and IS, respectively) may cause macrophage immune dysfunction. Results obtained indicated that intracellular oxidation level and cytotoxicity markedly increased upon treatment with indole and indoxyl, in comparison with IS. Incubation of the cells with indole and indoxyl also resulted in attenuated phagocytic activity. Human serum albumin (HSA)-binding assay confirmed that tryptophan and IS, but not indole and indoxyl, could selectively bind to the site II in HSA. Collectively, the results indicated that indole and indoxyl may strongly down-regulate the phagocytic immune function of macrophages, whereas IS, formed upon sulfate conjugation of indoxyl, may exhibit enhanced HSA-binding capability, thereby reducing the adverse effects of indoxyl.

Copper-Catalyzed Tandem O-Vinylation of Arylhydroxylamines/[3,3]-Rearrangement/Cyclization: Synthesis of Highly Substituted Indoles and Benzoindoles

Herein, we developed a copper-catalyzed O-vinylation of arylhydroxylamine using vinyliodonium salts as vinylation reagents to generate a transient O-vinyl-N-arylhydroxylamine that rapidly undergoes a [3,3]-sigmatropic rearrangement and subsequent cyclization/rearomatization to form a substituted indole. A wide range of highly substituted indoles and benzoindoles can be afforded in good yields. This approach is readily scalable, and the scope and application of this process are presented.

Metal-Free Multicomponent Construction of Tetrahydroisoquinoline-Indole Derivatives via In Situ Generated ortho-Quinonoid Intermediate

A metal- and ligand-free multicomponent coupling of tetrahydroisoquinoline (THIQ), ortho-hydroxybenzaldehydes and indoles under solvent-free conditions is described. The developed protocol provided a waste-free and concise access to C(1)-functionalized THIQ-indole derivatives under green conditions. The reactant molar ratio and neutral conditions were found crucial for controlling the selectivity of desired THIQ-indole product over competitive by-products i. e. oxazine and bis(indolyl)methane. The experimental and DFT study revealed the involvement of ortho-quinonoid species which reacts with indoles in situ to form THIQ-indole derivatives.

Access to 3-Oxindoles from Allylic Alcohols and Indoles

The site-selective and regioselective allylation of 2-substituted indoles was performed by using a ruthenium(IV) precatalyst containing a phosphine-sulfonate chelate. Mono-, di-, and triallylated indoles were selectively obtained depending on the reaction conditions with the formation of water as the only byproduct. The preparation of 3-oxindole derivatives was then successfully performed owing to air oxidation of the corresponding allylated indoles. Diallylated pseudoindoxyls were proven to be good synthons to perform cyclization through a ring-closing metathesis reaction to afford the corresponding tricyclic adducts. The photophysical properties of the 3-oxindoles were measured, and some of the compounds showed strong fluorescence in water.

P-III-Chelation-Assisted Indole C7-Arylation, Olefination, Methylation, and Acylation with Carboxylic Acids/Anhydrides by Rhodium Catalysis

Rhodium-catalyzed C7-selective decarbonylative arylation, olefination, and methylation of indoles with carboxylic acids or anhydrides by C-H and C-C bond activation have been developed. Furthermore, C7-acylation products can also be generated selectively at a lower reaction temperature in the developed system. The key to the high reactivity and regioselectivity of this transformation is the appropriate choice of an indole N-PtBu2 chelation-assisted group. This method has many advantages, including easy access and removal of the directing group, the use of cheap and widely available coupling agents, no requirement of an external ligand or oxidant, a broad substrate scope, high efficiency, and the formation of a sole regioisomer.

Regioselective Palladium-Catalyzed C-H Bond Trifluoroethylation of Indoles: Exploration and Mechanistic Insight

A selective palladium-catalyzed trifluoroethylation reaction of indoles has been developed. The C-H bond activation process, using CF3CH2I as the fluoroalkyl source, can be employed to prepare a variety of 2-CF3CH2 substituted indoles. Moreover, because it displays a wide functional group tolerance, the process can be employed to synthesize CF3CH2-containing bioactive indoles through late-stage trifluoroethylation. The results of a preliminary mechanistic study and DFT calculations show that a beta-diketone, acting as an ionic palladium ligand, plays an important role in governing the efficiency of the palladium-catalyzed trifluoroethylation reaction by accelerating the oxidative addition step. In contrast, transfer of the indole N-H proton in the palladium center is involved in the rate-determining step.

Pharmacophore-based screening of diamidine small molecule inhibitors for protein arginine methyltransferases

Protein arginine methyltransferases (PRMTs) are essential epigenetic and post-translational regulators in eukaryotic organisms. Dysregulation of PRMTs is intimately related to multiple types of human diseases, particularly cancer. Based on the previously reported PRMT1 inhibitors bearing the diamidine pharmacophore, we performed virtual screening to identify additional amidine-associated structural analogs. Subsequent enzymatic tests and characterization led to the discovery of a top lead K313 (2-(4-((4-carbamimidoylphenyl)amino)phenyl)-1H-indole-6-carboximidamide), which possessed low-micromolar potency with biochemical IC50 of 2.6 mu M for human PRMT1. Limited selectivity was observed over some other PRMT isoforms such as CARM1 and PRMT7. Molecular modeling and inhibition pattern studies suggest that K313 is a nonclassic noncompetitive inhibitor to PRMT1. K313 significantly inhibited cell proliferation and reduced the arginine asymmetric dimethylation level in the leukaemia cancer cells.
