Monoterpenoid indole alkaloids from the stems of Kopsia officinalis

Five new indole alkaloids, kopsiofficines H-L (1-5), along with fourteen known alkaloids (6-19) were isolated from the stems of Kopsia officinalis. Their structures were elucidated by extensive NMR, mass spectroscopic analyses and comparison to the reported data. All the isolated compounds were evaluated their anti-inflammatory activities by inhibiting IL-1 beta, PGE2 and TNF-alpha secretion in lipopolysaccharide (LPS)-activated RAW264.7 cells. Compounds 2, 3, 6, 7, 11, 12, 15, and 17 show significant anti-inflammatory activities. These results demonstrate pharmacodynamic substance basis of these folkloric claims.

Application of 58749-22-7, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 58749-22-7 is helpful to your research.

Mapping insoluble indole metabolites in the gastrointestinal environment of a murine colorectal cancer model using desorption/ionisation on porous silicon imaging

Indole derivatives are a structurally diverse group of compounds found in food, toxins, medicines, and produced by commensal microbiota. On contact with acidic stomach conditions, indoles undergo condensation to generate metabolites that vary in solubility, activity and toxicity as they move through the gut. Here, using halogenated ions, we map promising chemo-preventative indoles, i) 6-bromoisatin (6Br), ii) the mixed indole natural extract (NE) 6Br is found in, and iii) the highly insoluble metabolites formed in vivo using desorption/ionisation on porous silicon-mass spectrometry imaging (DIOS-MSI). The functionalised porous silicon architecture allowed insoluble metabolites to be detected that would otherwise evade most analytical platforms, providing direct evidence for identifying the therapeutic component, 6Br, from the mixed indole NE. As a therapeutic lead, 0.025 mg/g 6Br acts as a chemo-preventative compound in a 12 week genotoxic mouse model; at this dose 6Br significantly reduces epithelial cell proliferation, tumour precursors (aberrant crypt foci; ACF); and tumour numbers while having minimal effects on liver, blood biochemistry and weight parameters compared to controls. The same could not be said for the NE where 6Br originates, which significantly increased liver damage markers. DIOS-MSI revealed a large range of previously unknown insoluble metabolites that could contribute to reduced efficacy and increased toxicity.

Indol-2-Carboxylic Acid Esters Containing N-Phenylpiperazine Moiety – Preparation and Cholinesterase-inhibiting Activity

Background: The indole derivatives and the N-phenylpiperazine fragment represent interesting molecular moieties suitable for the research of new potentially biologically active compounds. This study was undertaken to identify if indol-2-carboxylic acid esters containing N-phenylpiperazine moiety possess acetyleholinesterase and butyrylcholinesterase inhibitory activity. Materials and Methods: The study dealt with the synthesis of a novel series of analogs of 1H-indole-2-carboxylic acid and 3-methyl-1H-indole-2-carboxylic acid. The structure of the derivatives was represented by the indolylcarbonyloxyaminopropanol skeleton with the attached N-phenylpiperazine or diethylamine moiety, which formed a basic part of the molecule. The final products were synthesized as dihydrochloride salts, fumaric acid salts, and quaternary ammonium salts. The first step of the synthetic pathway led to the preparation of esters of 1H-indole-2-carboxylic acid from the commercially available 1H-indole-2-carboxylic acid. The Fischer indole synthesis was used to synthesize derivatives of 3-methyl-1H-indole-2-carboxylic acid. Results and Discussion: Final 18 indolylcarbonyloxyaminopropanols in the form of dihydrochlorides, fumarates, and quaternary ammonium salts were prepared using various optimization ways. The very efficient way for the formation of 3-methyl-1H-indole-2-carboxylate (Fischer indole cyctization product) was the one-pot synthesis of phenylhydrazine with methyl 2-oxobutanoate with acetic acid and sulphuric acid as catalysts. Conclusion: Most of the derivatives comprised of an attached N-phenylpiperazine group, which formed a basic part of the molecule and in which the phenyl ring was substituted in position C-2 or C-4. The synthesized compounds were subjected to cholinesterase-inhibiting activity evaluation, by modified Ellman method. Quaternary ammonium salt of 1H-indole-2-carboxylic acid which contain N-phenylpiperazine fragment with nitro group in position C-4 (7c) demonstrated the most potent activity against acetylcholinesterase.

Two-Way Regulation of MmpL3 Expression Identifies and Validates Inhibitors of MmpL3 Function in Mycobacterium tuberculosis

MmpL3, an essential mycolate transporter in the inner membrane of Mycobacterium tuberculosis (Mtb), has been identified as a target of multiple, chemically diverse antitubercular drugs. However, several of these molecules seem to have secondary targets and inhibit bacterial growth by more than one mechanism. Here, we describe a cell-based assay that utilizes two-way regulation of MmpL3 expression to readily identify MmpL3-specific inhibitors. We successfully used this assay to identify a novel guanidine-based MmpL3 inhibitor from a library of 220 compounds that inhibit growth of Mtb by largely unknown mechanisms. We furthermore identified inhibitors of cytochrome bc(1)-aa(3) oxidase as one class of off-target hits in whole-cell screens for MmpL3 inhibitors and report a novel sulfanylacetamide as a potential QcrB inhibitor.

Modulatory Effect of Indoles on the Expression of miRNAs Regulating G1/S Cell Cycle Phase in Breast Cancer Cells

Indole-3-carbinol (I3C) is a naturally occurring glucosinolate found in Brassica vegetables that is usually converted in gastric acidic environment to the efficient metabolite 3,3 ‘-diindolylmethane (DIM). Both indoles (I3C and DIM) are known chemopreventive agents for various cancers including breast cancer. This study aimed to investigate the influence of both indoles on the tumor suppressor miRNAs (let-7a-e, miR-15a, miR-16, miR-17-5p, miR-19a, and miR-20a) and oncomiRs (miR-181a, miR-181b, miR-210, miR-221, and miR-106a), which are controlling the cell cycle key regulators: cyclin-dependent kinases (CDKs), CDK inhibitor p27(Kip1), and cyclin D1. Our results indicated that both indoles generally elevated the expression of the tumor suppressor miRNAs let-7a-e, miR-19a, miR-17-5p, and miR-20a and decreased the expression of the oncomiR list. Both indoles were able to significantly suppress the expression of CDK4 and CDK6 as well as the apoptotic markers Bcl-2 and survivin. Both indoles decreased cyclin-D1 protein, where I3C decreased cytoplasmic and nuclear cyclin-D1 significantly. Cytoplasmic and nuclear P27(Kip1)showed overexpression following treatment with I3C higher than that detected following DIM treatment. This study provides a mechanistic elucidation of the previously reported cell cycle arrest by I3C and DIM in breast cancer cells suggesting that this effect could be through modulation of miRNAs expression that, in turn, regulates the genetic network controlling the G1/S phase in cell cycle progression.

Stable Bromiranium Ion Salts as Reagents for Biomimetic Indole Terpenoid Cyclizations

Indole terpene alkaloids are a diverse group of natural products and show significant biological activities. To enable their biomimetic synthesis, electrophilic bromocyclization of polyenyl indole derivatives could be achieved using sterically demanding bromiranium ion salts with the weakly coordinating counterion BArF- as reagent. Starting from polyenyl indole derivatives, the corresponding bromocyclization products have been obtained with very high diastereoselectivity and in good yields.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 109-00-2. Recommanded Product: Pyridin-3-ol.

Enantioselective Synthesis of 2-Amino-1,1-diarylalkanes Bearing a Carbocyclic Ring Substituted Indole through Asymmetric Catalytic Reaction of Hydroxyindoles with Nitroalkenes

An asymmetric catalytic reaction of hydroxyindoles with nitroalkenes leading to the Friedel-Crafts alkylation in the carbocyclic ring of indole is presented. The method is based on the activating/directing effects of the hydroxy group situated in the carbocyclic ring of the indole providing nitroalkylated indoles functionalizated at the C-4, C-5, and C-7 positions with high yield, regio-, and enantioselectivity. The optically enriched nitroalkanes were transformed efficiently in optically enriched 2-amino-1,1-diarylalkanes bearing a carbocyclic ring substituted indole.

Impact of metal-oxide nanoparticles on growth, physiology and yield of tomato (Solanum lycopersicum L.) modulated by Azotobacter salinestris strain ASM

The current study for the first time demonstrates the interference of a free-living, N-2 -fixing, and nanoparticle (NP) tolerant Azotobacter salinestris strain ASM recovered from metal-polluted soil with tomato plant-metal oxide NPs (ZnO, CuO, Al2O3 , and TiO2) interactions in a sandy clay loam soil system with bulk materials as control. Tomato plants were grown till full maturity in soils amended with 20-2000 mg kg(-1) of each metal-oxide NP with and without seed biopriming and root-inoculation of A. salinestris. A. salinestris was found metabolically active, producing considerably high amounts of bioactive indole-3-acetic-acid, morphologically unaffected, and with low alteration of cell membrane permeability under 125-1500 mu gml(-1) of NPs. However, ZnO-NPs slightly alter bacterial membrane permeability. Besides, A. salinestris secreted significantly higher amounts of extracellular polymeric substance (EPS) even under NP exposure, which could entrap the NPs and form metal-EPS complex as revealed and quantified by SEM-EDX. NPs were also found adsorbed on bacterial biomass. EPS stabilized the NPs and provided negative zeta potential to NPs. Following soil application, A. salinestris improved the plant performance and augmented the yield of tomato fruits and lycopene content even in NPs stressed soils. Interestingly, A. salinestris inoculation enhanced photosynthetic pigment formation, flower attributes, plant and fruit biomass, and reduced proline level. Bacterial inoculation also reduced the NP’s uptake and accumulation significantly in vegetative organs and fruits. The organ wise order of NP’s internalization was roots > shoots > fruits. Conclusively, A. salinestris inoculation could be an alternative to increase the production of tomato in metal-oxide NPs contaminated soils. (C) 2020 Elsevier Ltd. All rights reserved.
