The Signaling Molecule Indole Inhibits Induction of the AR2 Acid Resistance System in Escherichia coli

Induction of the AR2 acid response system of Escherichia coli occurs at a moderately low pH (pH 5.5) and leads to high levels of resistance to pH levels below 2.5 in the presence of glutamate. Induction is mediated in part by the EvgAS two component system. Here, we show that the bacterial signaling molecule indole inhibits the induction of key promoters in the AR2 system and blocks the development of glutamate-dependent acid resistance. The addition of tryptophan, the precursor for indole biosynthesis, had the same effects, and this block was relieved in a tnaA mutant, which is unable to synthesize indole. Expression of a constitutively active EvgS protein was able to relieve the inhibition caused by indole, consistent with EvgS being inhibited directly or indirectly by indole. Indole had no effect on autophosphorylation of the isolated cytoplasmic domain of EvgS. This is consistent with a model where indole directly or indirectly affects the ability of EvgS to detect its inducing signal or to transduce this information across the cytoplasmic membrane. The inhibitory activity of indole on the AR2 system is not related to its ability to act as an ionophore, and, conversely, the ionophore CCCP had no effect on acid-induced AR2 promoter activity, showing that the proton motive force is unlikely to be a signal for induction of the AR2 system.

A micellar catalysis strategy applied to the Pd-catalyzed C-H arylation of indoles in water

The selective control over multiple competing C-H sites would enable straightforward access to functionalized indoles. In this context, we report here a modular and selective C-H arylation of indoles following the micellar catalysis approach using the third generation designer surfactant SPGS-550-M in the presence of 1 mol% of [(cinnamyl)PdCl](2) under mild conditions. Thus, access to high value C-arylated (C-3 and C-2) indoles was achieved fulfilling the triple bottom line philosophy of green chemistry. The nature of the phosphine ligand was found to be critical for achieving site-selectivity, DPPF and DPPP being the most effective in promoting the arylation at C-3-H and C-2-H, respectively. The reaction is scalable and offers high chemo- (C vs. N) and regio-selectivity (C-3 vs. C-2) with a wide range of functional group tolerance. The surfactant aqueous solution can be recycled and reused without compromising on product yields.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 88321-09-9 is helpful to your research. Application In Synthesis of Aloxistatin.

A monoalkoxy phenyl group as a dummy ligand on indolyl(aryl)iodonium imides, which is related to the N-I bonding hypervalent iodine(III) compound, for the copper-catalyzed indole-selective C-N coupling reaction was designed to provide 3-bissulfonimido-indole derivatives in high yields.

Pseudomonas entomophila PE3 and its exopolysaccharides as biostimulants for enhancing growth, yield and tolerance responses of sunflower under saline conditions

Evaluation of plant growth promoting bacteria and the associated metabolites under saline conditions can be a potential eco-friendly remediation and productivity enhancement strategy. Salt-tolerant Pseudomonas entomophila PE3 was isolated from saline soil and screened for plant growth promoting (PGP) traits. The isolate produced indole acetic acid (IAA), gibberellic acid (GA), exopolysaccharides (EPS) and siderophore along with the potential to solubilize potassium (K), zinc (Zn) and phosphorus (P). Maximum stimulation of PGP attributes was recorded at 2% NaCl concentration. To determine the role of EPS, their composition was analyzed (at different salt concentrations) and comparison was done to determine the changes upon exposure to salinity. EPS was found to be rich in carbohydrates, proteins and phenolic compounds. The extracted EPS were also found to possess salt-tolerance properties including antioxidant, hydroxyl scavenging activity, reducing power, emulsification and flocculation potential, and Na+ accumulation ability. Interestingly, the salt tolerance properties of EPS were enhanced upon exposure to salinity (2% NaCl). Finally, EPS based bioformulation of isolate PE3 was checked through field assay in saline soil. With promising results on growth promotion and improved salinity tolerance attributes of inoculated sunflower plants, the bioformulation of PE3 amended with EPS can be a breakthrough for remediation of saline-agroecosystems.

Unified enantioselective total syntheses of (-)-scholarisine G, (+)-melodinine E, (-)-leuconoxine and (-)-mersicarpine

A unified strategy enabled the enantioselective syntheses of (-)-scholarisine G, (+)-melodinine E, (-)-leuconoxine and (-)-mersicarpine from a common 2-alkylated indole intermediate bearing an all-carbon quaternary stereogenic center. The Smith-modified Madelung indole synthesis was used to couple simple o-toluidine with chiral lactone (+)-8, incorporating the key elements for further cyclizations. Lactone (+)-8 was prepared via a palladium-catalyzed intermolecular asymmetric allylic alkylation. The unified and protecting-group-free reaction sequences allowed the synthesis of these alkaloids in a maximum of 10 steps and with high efficiency.

Identification and functional study of an iif2 gene cluster for indole degradation in Burkholderia sp. IDO3

Burkholderia sp. IDO3 is an indole-degrading bacterium isolated from activated sludge. A previous genomic clone library assay identified an iif1 gene cluster for indole metabolism in strain ID03. To further explore the underlying indole degradation mechanisms, the complete genome of strain IDO3 was sequenced (8,003,806 bp). The genome contained three circular chromosomes and one plasmid, and 7550 genes were predicted. Interestingly, in addition to iif1 on chromosome 3, bioinformatic analyses identified a second indole oxygenase gene cluster, iif2, on chromosome 1. Both iif clusters were up-regulated in response to indole. Heterologous expression of iifC1D1 and iifC2D2 in Escherichia coli BL21(DE3) demonstrated that these genes were capable of oxidizing indole to indigo. Gene knockout assays provided additional evidence that iifC2 played crucial roles in indole metabolism. In addition, we identified a novel gene (iifF) in the iif2 cluster. This gene was shown to encode an isatin hydrolase. IifF was expressed in E. coli, and a purified his-tagged enzyme preparation was obtained. IifF converted isatin to isatinate with K-m of 4.4 +/- 0.7 mu M and k(cat) of 95.5 +/- 4 s(-1). This is the first study to show that indole can be degraded by two iif gene clusters, and that isatin hydrolase is involved in indole metabolism, improving our understanding of indole metabolic processes.
