Monoterpenoid indole alkaloids from the fruits of Gelsemium elegans and their anti-inflammatory activities

Two novel monoterpenoid indole alkaloids (MIAs), gelsechizines A-B (1-2), along with four known ones (3-6) were isolated from the fruits of Gelsemium elegans. Compound 1 features a new carbon skeleton with two additional carbon atoms forming a 4-methylpyridine unit. Their structures with absolute configurations were elucidated by NMR, MS, X-ray diffraction and electronic circular dichroism (ECD) calculations. Compounds 1-3 showed significant anti-inflammatory effects in vivo and in vitro, which may be related to the inhibition of the trecruitment of neutrophils and macrophages as well as the secretion of TNF-alpha and IL-6. Preliminary structure-activity relationship analysis revealed that the beta-N-acrylate moiety plays an important role in the anti-inflammatory effect.

This synergistic process provides rapid access to functionalized dihydropyrimidoindolone and tricyclic [1,3]oxazino[3,4-a]indol-1-ones skeletons under redox neutral conditions with broad substrate scope and remarkable functional-group compatibility. Further late-stage modification of structurally complex drug molecules and mechanistic studies were also accomplished.

Synthesis, antimicrobial activity, and molecular docking study of fluorine-substituted indole-based imidazolines

A series of 2- or 3-(4,5-dihydro-1H-imidazol-2-yl)-1H-indole derivatives were synthesized, characterized, and evaluated for their in vitro antibacterial and antifungal activities. Additionally, the synthesized compounds were docked into the II DNA gyrase B active site, and their predicted binding modes were inspected. Inhibitory activity were tested against two species of Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), two species of Gram-positive bacteria (Staphylococcus aureus, Listeria monocytogenes) and two fungi (Candida albicans, Aspergillus niger) using the broth microdilution method. The fluorine-substituted 2-(2-imidazolyl)indole 2b was found to be the most potent antibacterial compound against E. coli and S. aureus strains (MIC value 80 mu g/mL). Compounds showed better activity against Gram-positive bacteria compared to Gram-negative bacteria. The docking results predicted that the imidazoline-indole hybrid moiety bind to the active site protein ATP-binding pocket from E. coli and S. aureus with good interaction energy scores. The significant loss of antibacterial activity for some imidazoline-indole analogs could be attributed to several nonoptimal enzyme interactions, including poor hydrogen bonds provided by Asp73 (E. coli gyrase numbering) or Asp81 (S. aureus gyrase numbering) and an associated water molecule.

Copper-Catalyzed Trifluoromethylation of Ynones Coupled with Dearomatizing Spirocyclization of Indoles: Access to CF3 -Containing Spiro[cyclopentane-1,3 ‘-indole]

A one-pot protocol for the Cu(I)-catalyzed difunctionalization of indolyl ynones has been achieved via trifluoromethylation of alkyne followed by dearomatizing spirocyclization of indoles.

In vitro activity of AST-120 that suppresses indole signaling in Escherichia coli, which attenuates drug tolerance and virulence

AST-120 (Kremezin) is used to treat progressive chronic kidney disease (CKD) by adsorbing uremic toxin precursors produced by gut microbiota, such as indole and phenols. In this study, we propose that AST-120 reduces indole level, consequently suppresses indole effects on induction of drug tolerance and virulence in Escherichia coli including enterohaemorrhagic strains. In experiments, AST-120 adsorbed both indole and tryptophan, a precursor of indole production, and led to decreased expression of acrD and mdtEF which encode drug efflux pumps, and elevated glpT, which encodes a transporter for fosfomycin uptake and increases susceptibility to aztreonam, rhodamine 6G, and fosfomycin. AST-120 also decreased the production of EspB, which contributes to pathogenicity of enterohaemorrhagic E. coli (EHEC). Aztreonam, ciprofloxacin, minocycline, trimethoprim, and sulfamethoxazole were also adsorbed by AST-120. However, fosfomycin, in addition to rifampicin, colistin and amikacin were not adsorbed, thus AST-120 can be used together with these drugs for therapy to treat infections. These results suggest another benefit of AST-120, i.e., that it assists antibacterial chemotherapy.

Application of 320-67-2, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 320-67-2.

Use of Thidiazuron for High-Frequency Callus Induction and Organogenesis of Wild Strawberry (Fragaria vesca)

Strawberry, belonging to the Fragaria genus, is an important crop that produces popular fruits globally. F. vesca, known as wild strawberry, has great characteristics, such as a robust and powerful aroma, making it an important germplasm resource. The present study aims to establish an efficient regeneration method for the in vitro propagation of F. vesca. Firstly, leaf explants were used to induce callus formation on a Murashige and Skoog medium with combinations of cytokinins (thidiazuron (TDZ) and 6-benzylaminopurine (BA)) and auxin (2,4-dichlorophenoxyacetic acid (2,4-D)). Among them, 0.45-4.54 mu M TDZ combined with 0.45-4.53 mu M 2.4-D exhibited a high induction rate after 4 weeks of culturing. Different explants were examined for their ability to form a callus, and whole leaves on the medium containing 2.27 mu M TDZ and 2.27 mu M 2,4-D showed the highest callus induction rate at 100% after 2 weeks of culturing in darkness. The highest shoot regeneration ability through organogenesis from the callus was obtained at 0.44 mu M BA. After 2 weeks of culturing, the shoot regeneration rate and shoot number per explant were 96% and 19.4 shoots on an average, respectively. Rooting of shoots was achieved using indole-3-butyric acid (IBA) or an alpha-naphthaleneacetic acid (NAA)-containing medium, and the resulting plantlets were acclimatized successfully and formed flowers eventually. In this report, we demonstrated that shoot organogenesis was derived from the meristematic cells of calli and by transferring the induced calli to a 0.44 mu M BA medium, the regeneration period can be shortened greatly. A protocol for the efficient regeneration of wild strawberry was established, which might be useful for their large-scale propagation or obtaining transgenic plants in the future.

Total Synthesis of (-)-Alstofolinine A: Selected Furan Oxidation/Cyclization Cascade

Indole-fused tetracyclic ring systems containing nitrogen atoms are common core skeletons of many indole alkaloids such as sarpagine, macroline, and ajmaline. Efficient and stereoselective construction of these ring systems can promote the development of the corresponding alkaloid syntheses. In this article, we briefly summarize our current progress toward the application of the aza-Achmatowicz reaction and indole nucleophilic addition reaction cascade for the first asymmetric total synthesis of the macroline-type indole alkaloid (-)-Alstofolinine A. Our synthetic strategy is based on furan oxidation/rearrangement and proceeds from easily accessible materials such as indole and furan derivatives.

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 96-97-9 is helpful to your research. Recommanded Product: 2-Hydroxy-5-nitrobenzoic acid.
