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.

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.

Concise approach to the syntheses of (+/-)-gliocladin C and related diketopiperazine alkaloids

A unique approach to the diketopiperazine indole alkaloid (+/-)-gliocladin C was developed and applied to formal syntheses of the related alkaloids (+/-)-gliocladine C and (+/-)-T988C. The key features of the strategy include an unprecedented nucleophilic addition of a diketopiperazine to an isatin derivative followed by a Friedel-Crafts alkylation of the resultant tertiary alcohol with indole to establish the critical quaternary center. Subsequent reduction of the intermediate oxindole moiety and cyclization then delivered a pivotal hexahydropyrrolo[2,3-b]indole diketopiperazine intermediate that was readily converted into (+/-)-gliocladin C as well as racemic versions of key intermediates in the Overman syntheses of (+)-gliocladine C and (+)-T988C.

Unusual rearrangements in activated indoles: Synthesis of indoloquinolines, dibenzonaphthyridines and indolobenzodiazepines

Reaction of 2-arylindoles with 2-acetamidobenzyl chloride gave 3-alkylated indoles rather than those substituted at nitrogen. Similar reactions with 3-arylindoles gave reduced indoloquinolines, and a 2,3-diphenylindole gave a 3-alkylated indole. On reaction with phosphoryl chloride, the amidobenzylindoles undergo rearrangement to benzonaphthyridines. Similarly, the indoloquinolines undergo rearrangement to benzodiazepino-indoles.

Weak Coordinating Carbonyl-Directed Rhodium(III)-Catalyzed C-H Activation at the C4-Position of Indole with Allyl Alcohols

A weakly coordinating carbonyl-directed coupling of allyl alcohols at the C-4 position of indole derivatives under the C-H activation conditions catalyzed by Rh(III) is reported. This results in alkylation at the C-4 position of indole derivatives exclusively. The obtained product forms a tricyclic derivative under aldol reaction conditions, which can be a potential precursor for synthesizing a few alkaloid molecules such as ergot, hapalindole alkaloids, and related heterocyclic compounds.

Indole-based alkaloids from Ophiocordyceps xuefengensis

Seven undescribed indole-based alkaloids, xuefengins A-D and xuefenglasins A-C, were isolated from natural Ophiocordyceps xuefengensis, along with six known alkaloids. Their structures were elucidated by comprehensive spectroscopy, with absolute configurations confirmed by comparison with calculated electronic circular dichroism spectra. Eleven of the isolates were tested for cytotoxicity against the U937, NB4, MCF-7, Hep G2, and A549 cancer cell lines. Two compounds exhibited moderate activities, with IC50 values of 2.83-25.68 mu M and 1.54-12.16 mu M. Further pharmacological studies showed that these two compounds inhibit cell proliferation by inducing apoptosis, and decreasing p38 and caspase-3 levels in A549 cells.

Regiodivergent Trifluoromethanesulfonic Acid-Promoted Cycloisomerizations of Ynenamines to Fused Indoles

Trifluoromethanesulfonic acid (TfOH)-mediated cycloisomerizations were controlled through the choice of the electron-withdrawing functional group at C3 of indoles to provide pyrrolo[3,2,1-ij]quinolines and benzo[3,4]azepino[1,2-a]indoles via 6-endo-dig and 7-endo-dig cyclizations, respectively. The natures of the different cyclizations could be controlled by tuning the electronic influences; indole substrates with carbonyl groups (such as -CO2Et and -COMe) gave products with six-membered rings, while substrates with sulfonyl groups (such as -Ts and -Ms) gave products with seven-membered rings in moderate to good yields. By comparison, electronically-neutral substituents (such as -Ph and -H) turned out to give seven-membered products through different mechanism.

Synergistic Dual Role of [hmim]Br-ArSO2Cl in Cascade Sulfenylation-Halogenation of Indole: Mechanistic Insight into Regioselective C-S and C-S/C-X (X = Cl and Br) Bond Formation in One Pot

Bifunctionalized indoles are an important class of biologically active heterocyclic compounds and potential drug candidates. Because of the lack of efficient synthetic methods, one pot cascade synthesis of these compounds is rare and remains a challenge. To expand this field, we herein disclose a step-economical and temperature tunable strategy wherein the synergistic effect between [hmim]Br-ArSO2Cl leads exclusively to the formation of 3-arylthio indole via sulfenylation of indole at room temperature, while heating the reaction mixture at 50 degrees C provided an unexpected 2-halo-3-arylthio indole with construction of C-S and C-S/C-X (X = Cl and Br) bonds without addition of any external halogenating agent via cascade sulfenylation-halogenation reactions under metal-oxidant-base-free conditions. Further, insight into the reaction mechanism provides an unprecedented observation wherein the synergistic interaction between [hmim]Br-ArSO2X in the presence of a catalytic amount of water generates arylsulfonic anhydride (ArSO2)(2)O in situ as a new sulfur source along with the formation of [hmim]PTS as probed by NMR, ESI-MS, DART-MS, and HPLC studies. Notably, the mixture of bifunctionalized 2-halo(Br/Cl)-3-arylthio indole was smoothly diversified with privileged heterocycle triazole to provide 2-(1H-triazole-1-yl)-3-arylthio indole, which is an analogue of the potent indole-based anticancer agent.
