Decarboxylation of indole-3-carboxylic acids under metal-free conditions

Two reaction systems have been developed for the decarboxylation of indole-3-carboxylic acids. The decarboxylation can be achieved smoothly under K2CO3-catalyzed or acetonitrile-promoted basic conditions. It provided an efficient and simple method for the transformation of indole-3-carboxylic acids and the corresponding indoles were isolated with good to excellent yields. From the experimental facts, we put forward the possible reaction mechanism.

Oxidative Pictet-Spengler cyclisations through acceptorless iridium-catalysed dehydrogenation of tertiary amines

The valuable tetrahydro-beta- and gamma-carboline skeleta can be accessed through Pictet-Spengler cyclisation initiated by acceptorless dehydrogenation of saturated cyclic amines. The substrate scope for the beta-isomers is found to be somewhat limited, but access to the gamma-isomers through the more reactive 2(aminoethyl)indoles is more general. The synthetic utility of hydrogen transfer catalysis is highlighted in a two-step preparation of the alkaloid desbromoarborescidine A by sequential redox-neutral alkylation/ de hyd roge native cyclisation.

Metabolomic analysis to detect urinary molecular changes associated with bipolar depression

Bipolar disorder (BD) is a debilitating mental disorder with complex clinical manifestations and low diagnostic accuracy. Depressive episodes are most common in the course of BD with high comorbidity and suicide rates, which present greater clinical challenges than mania and hypomania episodes. However, there are no objective biomarkers for bipolar depression. The aim of this study was to detect urinary metabolite biomarkers that could be useful for the diagnosis of bipolar depression. Nuclear magnetic resonance spectroscopy was used to profile urine samples of patients with bipolar depression (n = 37) and healthy volunteers (n = 48). Data were analyzed using Orthogonal Partial Least Square Discriminant Analysis and t-test. Differential metabolites were identified (VIP > 1 and p < 0.05), and further analyzed using Metabo Analyst 3.0 to identify associated metabolic pathways. In total, we identified seven metabolites differentially expressed in patients with BD and healthy controls. Compared with healthy group, the levels of betaine, glycerol, hippuric acid, indole sulfate, trimethylamine oxide, and urea in urine samples of BD patients were significantly higher, while the level of inositol was significantly lower. Most of these small molecules are related to lipid metabolism and gut microbiota metabolism. These differential metabolites could provide critical insight into the pathological mechanisms of bipolar depression. The results of this study provide a meaningful reference for similar and further studies in the future. Interested yet?

Catalytic Hydrodenitrogenation of Pyridine under Hydrothermal Conditions: A Comprehensive Study

This article focuses on the kinetic modeling and catalytic performance of hydrodenitrogenation of pyridine under hydrothermal conditions. Piperidine derivatives are the major nitrogen-containing intermediates, including 1-piperidinecarboxaldehyde, 1-piperidineethanol, and alkyl piperidines. Catalysts overall improved the formation of N-free products including 1-pentanol and 2-methyl-1-pentanol. Commercial Pd/C provided the highest pyridine conversion rate at 350 degrees C, while the homemade Ni-Ru bimetallic catalyst provided a prominent denitrogenation activity at 400 degrees C, leading to the highest 1-pentanol yield as a major denitrogenated product. Conversion of pyridine over the Ni50Ru50/C catalyst led to formation of three major alkyl piperidines (1-ethyl piperidine, 1-methyl piperidine, and 1-pentyl piperidine). These alkyl piperidine intermediates could further be converted into amino and N-free compounds. A kinetic model was developed to mathematically describe the hydrothermal HDN reaction of pyridine over the Ni50Ru50/C catalyst, which clearly captured all data trends and fitted the temporal variation of all major products. Sensitivity analysis suggested that dehydrogenation from piperidine to pyridine has a strong impact on the whole reaction pathways.

Light-triggered elimination of CO2 and absorption of O-2 (artificial breathing reaction) in photolysis of 2-(4-nitrophenyl)-1H-indole derivatives

A new chromophore, 2-(4-nitrophenyl)-1H-indole (NPI), was synthesized as a potential photolabile protecting group. Caged benzoic acids featuring the NPI chromophore were synthesized as model compounds. Benzoic acid was released in moderate yields (similar to 40-60%) upon photolysis of the caged benzoic acids without any additional chemical reagents. Interestingly, an aldehyde, 1-(5-(1-formyl-1H-indo1-2-yl)-2-nitrophenyl)ethyl benzoate, was isolated in approximate to 20% together with benzoic acid 40%) in photolysis of a caged benzoic acid, 2-(2-(3-(1-(benzoyloxy)ethyl)-4-nitrophenyl)-1H-indol-1-yl)acetic acid. The functional group, CH2COOH, at the indole nitrogen was transformed into the aldehyde group, CHO, under photolysis conditions in air. The similar photochemical transformation was observed in the photolysis of 2-(2-(4-nitrophenyl)-1H-indol-1-yl)acetic acid, in which the benzoate group is not attached at the nitrophenyl ring. Products analysis, transient absorption spectroscopy, and computational study suggested that intramolecular electron transfer is key for the elimination of CO2 and absorption of O-2 for the formation of the aldehyde. The artificial breathing-type reaction can apply to transition metal-free oxidation of amino acids under mild conditions. [GRAPHICS] .

Biological potential of Bacillus subtilis V26 for the control of Fusarium wilt and tuber dry rot on potato caused by Fusarium species and the promotion of plant growth

Fusariosis of potato caused by the Fusarium spp. is one of the most destructive soil-borne diseases throughout the world. This study aimed to investigate the growth-promoting and biocontrol potential of Bacillus subtilis V26 against the causal agents of Fusarium wilt and Fusarium dry rot diseases on potato. Characterization of plant growth promoting traits was assessed in vitro. The strain V26 was able to fix nitrogen, to produce indole-3-acetic acid, siderophore, hydrolytic enzymes and to solubilize inorganic phosphate. The PCR detection of ituC, fenA, fenB, fenD, srfAA, bmy, mnlA, bae and bac genes coding for iturin, fengycin, surfactin, bacyllomicin, macrolactin, bacillaene and bacilysin indicated a potential for lipopeptides, polyketides and dipeptide production, respectively by the strain V26. In vitro antagonism test showed that this strain can effectively inhibit F. oxysporum, F. solani, F. gramineaurum and F. sambucinum growth by 54.7 to 85.3% as compared to the untreated control, in a dual method. Antifungal activity was demonstrated against the dry rot potato tubers caused by Fusarium species. The preventive application of V26 significantly decreased the Fusarium dry rot disease severity at 42.8-63.8%, after 21 days of fungi inoculation. After 15 days of seedling emergence, plants were irrigated with V26 spore suspensions (108 CFU/mL), prior infection by Fusaium species, Fusarium wilt severity were reduced by 54.8 to 60.8% and plant growth parameters were improved, compared to the untreated ones, 60 days post-inoculation. Therefore, this strain could be a promising candidate to be developed as commercial biofertilizer and biocontrol formulation in sustainable agriculture.

A multicomponent reaction to design antimalarial pyridyl-indole derivatives: Synthesis, biological activities and molecular docking

Using fragment-based design strategy, new pyridyl-indole hybrids 4a-y and indole intermediates 3a-e were synthesized using multicomponent one pot reaction. The synthesized compounds were subjected to screening for antimalarial activity against chloroquine sensitive (D6) and chloroquine resistant (W2) strains of Plasmodium falciparum. Several compounds exhibited antimalarial activity with IC50 values in the range of 1.47-9.23 mu M, and 1.16-7.66 mu M, for D6 and W2 strains, respectively. Compounds 4a, 4k and 4u showed the highest selectivity index among all the tested compounds (S.I. ranged 3.8-10). Binding interactions between the active antimalarial compounds and the active site of quadruple mutant Plasmodium falciparum dihydrofolate reductase enzyme have been investigated using molecular docking analysis.

Copper-Catalyzed Chemodivergent Cyclization of N-(ortho-alkynyl)aryl-Pyrrole and Indoles

Herein, we described an efficient copper-catalyzed chemo-divergent tandem reaction of N-(ortho-alkynyl)aryl-pyrrole and (iso)indoles, delivering ring-fused N-heterocycles in good yields in an atom-economical manner. N-(ortho-alkynyl)aryl-pyrrole and indoles undergo the tandem cyclization/migration reaction, in which the group at 2-position was migrated to 3-position. In contrast, the dearomative cyclization of N-(ortho-alkynyl)aryl-isoindoles would occur to deliver the N-fused tetracyclic products efficiently.

Melotenuines A-E, cytotoxic monoterpenoid indole alkaloids from Melodinus tenuicaudatus

Five new monoterpenoid indole alkaloids, melotenuines A-E (1-5), along with 18 known indole alkaloids, were isolated from the twigs and leaves of Melodinus tenuicaudatus. The structures of the new alkaloids were determined by a combination of MS, NMR and ECD analysis. Melotenuine A (1) represents the first example of aspidosperma-meloscandonine type bisindole alkaloids characterized by a methylene bridge between the two monomers, while melotenuine B (2) possessed a rare eburnamine-melsocandonine skeleton. All of the new indole alkaloids were evaluated for in vitro cytotoxicities against five human cancer cell lines. Among them, alkaloid 4 showed specific cytotoxicity against HL-60 cell line with IC 50 value (5.15 +/- 0.16 mu M) comparable with that of positive control.
