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?

The Primary Physiological Roles of Autoinducer 2 in Escherichia coli Are Chemotaxis and Biofilm Formation

Autoinducer 2 (AI-2) is a ubiquitous metabolite but, instead of acting as a universal signal, relatively few phenotypes have been associated with it, and many scientists believe AI-2 is often a metabolic byproduct rather than a signal. Here, the aim is to present evidence that AI-2 influences both biofilm formation and motility (swarming and chemotaxis), using Escherichia coli as the model system, to establish AI-2 as a true signal with an important physiological role in this bacterium. In addition, AI-2 signaling is compared to the other primary signal of E. coli, indole, and it is shown that they have opposite effects on biofilm formation and virulence.

Enantioselective N-Heterocyclic Carbene-Catalyzed Cascade Reaction for the Synthesis of Pyrroloquinolines via N-H Functionalization of Indoles

Functionalization of the indole N-H bond for enantioselective synthesis of biologically important pyrroloquinoline derivatives has been reported under oxidative N-heterocyclic carbene catalysis conditions. The interception of catalytically generated chiral alpha,beta-unsaturated acylazoliums with the indole derivatives proceeds in an aza-Michael/Michael/lactonization sequence to deliver the pyrroloquinoline derivatives in good yields, diastereoselectivities, and enantioselectivities. The simultaneous enhancement of reactivity and selectivity observed in polar aprotic solvents is noteworthy.

Dialkylation of Indoles with Trichloroacetimidates to Access 3,3-Disubstituted Indolenines

2-Substituted indoles may be directly transformed to 3,3-dialkyl indolenines with trichloroacetimidate electrophiles and the Lewis acid TMSOTf. These reactions provide rapid access to complex indolenines which are present in a variety of complex natural products and medicinally relevant small molecule structures. This method provides an alternative to the use of transition metal catalysis. The indolenines are readily transformed into spiroindoline systems which are privileged scaffolds in medicinal chemistry.

Newly isolated Bacillus sp. PS-6 assisted phytoremediation of heavy metals using Phragmites communis: Potential application in wastewater treatment

This work aimed to study Bacillus sp. PS-6 assisted phytoremediation of metals from pulp and paper industry wastewater as a novel green technique for the removal of metals of wastewater. Results revealed that heavy metal (mg L-1) contents in wastewater were reduced after in-situ phytoremediation for Fe, Cu, Zn, Cd, Mn, Ni, Pb, and As. Phragmites communis showed higher potential for the enrichment of Fe, Cu, Zn, Cd, Mn, Ni, Pb, and As in its rhizomes, roots, and shoots compared to leaves. The strain produced indole acetic acid, siderophores, and hydrolytic and ligninolytic enzymes, and resulted in nutrients solubilization. Results offer potential basis for the removal of metals from pulp and paper industry wastewater at large scale and prevention of pollution.

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 52927-22-7 is helpful to your research. Name: 6-Hydroxy-2-naphthonitrile.

SYNTHESIS OF DIBENZO[cd, g]INDOLE

In this paper, a synthesis method is proposed and discussed for a compound not previously described – dibenzo [cd, g] indole. For the successful synthesis of the target compound we used the classical method based on well-known procedure of indoles obtaining according to Fisher method with some changes. Commercially available derivatives of anthracene were used as the starting compound since they already contain a ready-made system of three condensed aromatic rings and they reaction activity is rather high. The corresponding diazonium salt was obtained from 9-amino anthracene by reaction with ethyl nitrite. Attempts to obtain the diazonium salt by reaction the amine with inorganic nitrites in an acidic aqueous medium did not lead to a product with an acceptable yield. 9-Antryl hydrazine was prepared by reducing the diazonium salt under mild conditions. Reduction was carried out using sulfur dioxide in aqueous sodium hydrosulfite. Formaldehyde of 9-anthrylhydrazone was obtained from anthrylhydrazine after condensation with paraformaldehyde. The target product was obtained by intramolecular cyclization of hydrazone under the action of BF3 * Et2O under the condition of high dilution and low temperature. The physicochemical characteristics of all the obtained compounds are determined. Melting point was determined on a Stuart SMP-30 instrument. IR spectra were recorded on a Nicolet 380 FT-IR spectrometer in tablets with potassium bromide. NMR spectra were recorded on a Bruker DRX-400 spectrometer (400 MHz), Me4Si was used as a H-1 standard, in CDCl3 as a solvent. Elemental analysis was performed on a EuroEA 3000 analyzer. Based on the data from the above analysis methods, it was concluded that the proposed structures correspond to the real ones. In addition, we can conclude that synthesized products are individual substances.

One-Pot Heteroarene Synthesis Based on Ruthenium-on-Carbon-Catalyzed Oxidative Aromatization Using Oxygen

Various heteroarenes, such as indole, carbazole, dibenzofuran, dibenzothiophene, etc., were easily constructed by the Diels-Alder reaction of the corresponding vinyl-substituted pyrrole, indole, benzofuran or benzothiophene with the dienophiles and the subsequent heterogeneously ruthenium-on-carbon (Ru/C)-catalyzed oxidative aromatization using oxygen in a one-pot manner.

[GRAPHICS] An efficient [8 + 2]/aryl-ene tandem reaction between azaheptafulvenes and arynes has been developed, leading to the formation of cyclohepta[b]indoles in a single step with good yield.

This is the first time that azaheptafulvenes have been employed in tandem reactions with arynes.
