Prenylated indole alkaloids and chromone derivatives from the fungus Penicillium sp SCSI0041218

Four new prenylated indole alkaloids (1-4), and four new chromone derivatives (7-10), together with six known compounds (5, 6, and 11-14), have been isolated from the mangrove sediment derived fungus Penicillium sp. SCSI0041218, cultured in the 1% NaCI PDB substrate. The structures of new compounds were determined by analysis of the NMR and MS spectroscopic data. The absolute configuration of the prenylated indole alkaloids were elucidated based on the comparison of ECDs with known analogues. The absolute configurations of the chromone derivatives were determined by time-dependent density functional theory calculations of the ECD spectra. In all of these isolated compounds, penixanthones A and B (12 and 13) exhibited antiallergic activities in vitro. (C) 2017 Elsevier Ltd. All rights reserved.

Catalytic Enantioselective Aminopalladation-Heck Cascade

Domino processes initiated by intramolecular nucleopalladation of alkynes have been developed into powerful synthetic tools for the synthesis of functionalized heterocycles. However, a catalytic enantioselective version of this class of reactions remains scarce. We report herein that reaction of 2-alkynylanilines with prochiral cyclopentenes in the presence of a catalytic amount of Pd(OAc)(2), a chiral bidentate pyrox ligand and O-2 as terminal oxidant affords the structurally diverse indole-cyclopentene conjugates bearing two stereocenters in a highly diastereo- and enantio-selective manner. One of the products is converted to a heavily functionalized tetracyclic indolinone derivative.

Rhizobacteria associated with Miscanthus x giganteus improve metal accumulation and plant growth in the flotation tailings

Purpose Flotation tailings represent an extremely unfriendly substrate for plant colonization due to toxic metal concentrations and marked macronutrient deficiencies. The perennial grass Miscanthus x giganteus J.M.Greef & Deuter ex Hodk. & Renvoize was successfully cultivated in this infertile substrate for two years. Our aim was to identify composition of its rhizosphere bacterial community and to analyze the effects of the selected rhizobacteria on plant growth, root development, metal and P uptake. Methods Using the cultivation-dependent method, 75 isolates were collected from the rhizosphere and six rhizobacterial strains were selected for further characterization based on morphological and biochemical differences. The plant rhizomes were inoculated with the consortium of rhizobacteria and cultivated in the flotation tailings substrate. Results Detected bacterial strains were characterized as metal-resistant and plant growth-promoting rhizobacteria (PGPR) because of their metal tolerance (NiCl2, Pb(C2H3O2)(2), CuSO4, NaAsO2, MnCl2) and some or all of the plant growth-promoting (PGP) properties (indole-3-acetic acid and siderophore production, 1-aminocyclopropane-1-carboxylic acid deaminase activity and phosphate solubilization). PGPR mitigated the negative effects of high metal concentrations and macronutrient deficiency as shown by stimulated lateral roots development, increased root hair length, plant below and above ground biomass yield, higher plant P uptake and metal accumulation rate. Conclusions The isolated PGPR strains could be used in PGP-bacteria assisted phytoremediation of flotation tailings and metal polluted soils by M. x giganteus. Their PGP effects on various metal-tolerant target plant species in the respective substrate remain to be verified.

Visible-light mediated, catalyst-free synthesis of 3-indolyl-3-hydroxy oxindoles in water

For the first time, visible-light as a benign, green, and an inexpensive source has been successfully employed to the synthesis of 3-indolyl-3-hydroxy oxindoles in extremely mild reaction conditions in the absence of any catalyst. Using this sustainable photoinduced approach, various isatins and indoles containing electron withdrawing groups and electron-donating groups gave the corresponding products in moderate to good yield in water at room temperature. The formation of a CT complex between indoles and isatins is significant to proceed this photochemical reaction.

Design of Synthetic Polymer Nanoparticles Specifically Capturing Indole, a Small Toxic Molecule

Synthetic polymers are of interest as stable and cost-effective biomolecule-affinity reagents, since these polymers interact with target biomolecules both in vitro and in the bloodstream. However, little has been reported about orally administered polymers capable of capturing a target molecule and inhibiting its intestinal absorption. Here, we describe the design of synthetic polymer nanoparticles (NPs) specifically capturing indole, a major factor exacerbating chronic kidney disease, in the intestine. N-isopropylacrylamide-based NPs were prepared with various hydrophobic monomers. The amounts of indole captured by NPs depended on the structures and feed ratios of the hydrophobic monomers and the polymer density but not on the particle size. The combination of hydrophobic and quadrupole interaction was effective to enhance the affinity and specificity of NPs for indole. The optimized NPs specifically inhibited intestinal absorption of orally administered indole in mice. These results showed the potential of synthetic polymer NPs for inhibiting the intestinal absorption of a target molecule.
