Cannabis is an important industrial plant, in addition to its illicit drug use. Compound Delta(9)-THC (Delta(9)-tetrahydrocannabinol) is mainly responsible for the hallucinogenic effect on humans. The aminoalkylindole group cannabimimetics targets at the same physiological receptors to mimic the analgesic effects of Delta(9)-THC. Since there is no reliable colorimetric test to detect these synthetic cannabimimetics on site, a simple colorimetric assay for (aminoalkyl)indole group-containing drugs was developed, based on the silica/sulfuric acid-catalyzed Ehrlich reaction of (aminoalkyl)indoles with p-dimethylaminobenzaldehyde. The electrophilic substitution reaction of indoles with carbonyl compounds resulting in the formation of bis(indolyl)alkanes in an acid-catalyzed reaction has been used for the first time for their spectrophotometric determination by color change from yellow to purple/blue. The method was statistically validated against liquid chromatography tandem mass spectrometry, and applied to certain (aminoalkyl)indole derivatives, with 0.5 – 2.5 mu g mL(-1) detection limits for AM-2201, JWH-081, MAM-2201, JWH-018, JWH-210, JWH-122, 5F-PB-22 and XLR-11.

A convenient NaBr mediated procedure is developed for the preparation of 3-selanylindoles from indoles and diselenides. In this protocol, NaBr is first oxidized by mCPBA into molecular bromine, which reacts with diselenide to form RSeBr. The in situ generated active electrophilic selenium species, then reacts with indoles, affording a series of 3-selanylindoles with high regioselectivity and in moderate to good yields. [GRAPHICS] .

BACKGROUND & AIMS: Acetaminophen (APAP)-induced liver injury is one of the most common causes of acute liver failure, however, a dear definition of sensitizing risk factors is lacking. Here, we investigated the role of the ligand-activated transcription factor aryl hydrocarbon receptor (Ahr) in APAP-induced liver injury. We hypothesized that Ahr, which integrates environmental, dietary, microbial and metabolic signals into complex cellular transcriptional programs, might act as a rheostat for APAP-toxicity. METHODS: Wildtype or conditional Ahr knockout mice lacking Ahr in hepatocytes (Alb(Delta/Delta Ahr)) or myeloid cells (LysM(Delta/Delta Ahr)) were treated with the specific Ahr ligand 2-(1’H-indole-3′-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE) together with APAP. RESULTS: Ahr activation by ITE, which by itself was non-toxic, exacerbated APAP-induced hepatotoxicity compared to vehicle-treated controls, causing 80% vs. 0% mortality after administration of a normally sublethal APAP overdose. Of note, Ahr activation induced hepatocyte death even at APAP doses within the therapeutic range. Aggravated liver injury was associated with significant neutrophil infiltration; however, lack of Ahr in myeloid cells did not protect LysM(Delta/Delta Ahr) mice from exacerbated APAP hepatotoxicity. In contrast, Alb(Delta/Delta Ahr) mice were largely protected from ITE-induced aggravated liver damage, indicating that Ahr activation in hepatocytes, but not in myeloid cells, was instrumental for disease exacerbation. Mechanistically, Ahr activation fueled hepatic accumulation of toxic APAP metabolites by up-regulating expression of the APAP-metabolizing enzyme Cyp1a2, a direct Ahr downstream target. CONCLUSIONS: Ahr activation in hepatocytes potentiates APAP-induced hepatotoxicity. Thus, individual exposition to environmental Ahr ligands might explain individual sensitivity to hyperacute liver failure.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 371-41-5, Name is 4-Fluorophenol, SMILES is OC1=CC=C(F)C=C1, belongs to indole-building-block compound.

Sugarcane smut is a significant fungal disease that causes a major loss in sugar yield and quality. In this study, we isolated an endophytic strain B18 from a sugarcane root, which showed plant growth-promotion, hydrolytic enzyme production, antifungal activity against sugarcane pathogens (Sporisorium scitamineum, Ceratocystis paradoxa, Fusarium verticillioides), and the presence of nifH, acdS, and antibiotic genes (hcn, prn, and phCA) under in vitro conditions. BIOLOG((R)) phenotypic profiling of B18 established its ability to use various carbon and nitrogen sources and tolerate a range of pH and osmotic and temperature stresses. Whole-genome analysis of B18, identified as Pseudomonas aeruginosa, showed that it consists of a single circular chromosome of 6,490,014 bp with 66.33% GC content. Genome annotation has identified 5,919 protein-coding genes, and 65 tRNA, and 12 rRNA genes. The P. aeruginosa B18 genome encodes genes related to ethylene, nitrogen (nifU, norBCDERQ, gltBDPS, and aatJMPQ), and phosphate (pstABCS and phoBDHRU) metabolism and produce indole-3-acetic acid and siderophores. This also includes genes encoding hydrolases and oxidoreductases, those associated with biocontrol mechanisms (hcnABC, phzA_B, phzDEFGMS, and pchA), colonization (minCDE and lysC), and biofilm formation (efp, hfq, flgBCDEFGHI, and motAB), and those associated with metabolism of secondary metabolites. Collectively, these results suggest a role for P. aeruginosa B18 in plant growth enhancement and biocontrol mechanisms. The P. aeruginosa B18 strain was found to be an efficient colonizer in sugarcane; it can improve growth through modulation of plant hormone production and enhanced host-plant resistance to smut pathogen S. scitamineum in a smut-susceptible sugarcane variety (Yacheng71-374). These biocontrol and plant growth promotion properties of P. aeruginosa B18 area are discussed in this report.

Herein, we report a palladium-catalyzed dehydro-genative cross-coupling of indoles with cyclic enones to give beta-indolyl cyclic enones under mild and neutral reaction conditions. The key to the success is to explore a mild condition, which ensures the indole C-H activation and subsequent syn beta-hydride elimination through rapid enolization isomerization of Pd(II)-enolate while suppressing other undesired side reactions. Synthetic utility has also been demonstrated in the flexible transformation of the coupling products to meta-phenols and benzo [a] carbazoles.

Cyclometallated pi-allyliridium C,O-benzoates modified with (S)-tol-BINAP, which are stable to air, water, and SiO2, catalyze highly enantioselective N-allylations of indoles and related azoles. This reaction complements previously reported metal-catalyzed indole allylations in that complete levels of N versus C3 and branched versus linear regioselectivity are observed.
