Non-invasive qualitative urinary metabolomic profiling discriminates gut microbiota derived metabolites in the moderate and chronic alcoholic cohorts

Background: Excessive alcohol consumption damages the intestine and liver cells directly as well as through unbalancing the gut microbiota. Objective: The current study was undertaken to correlate the alcohol consumption and change in urinary metabolites profile linked with gut microbiota. Method: Non-alcoholic (control) healthy (n=22) and moderate alcoholic (n=26) males with an average age of 39.3¡À1.83 years subjected to alcohol use disorders identification test (AUDIT) were considered for study. First pass urine and blood samples were collected in the morning. Results: Liver function test showed the increased levels of gammaGT, AST and ALT to 40.3 ¡À 2.3, 53.3 ¡À 0.7, and 38.9 ¡À 0.5 U/L, respectively. Urine samples were processed and subjected to HPLC-Q-TOFMS analysis in positive and negative ion polarity modes. Mass data were processed to align and filter out insignificant entities and subjected to One-way ANOVA with Bonferroni multiple testing corrections analysis. The analysis provided list of 211gut microbes specific metabolites with p>0.05 and fold change ?1.5. All metabolites were identified using standards and referring to METALIN library of standard metabolites. Further analyses showed that alcohol intake disturbed more than ten metabolic pathways. Tryptophan, tyrosine, branched chain amino acids and short-chain fatty acids metabolism were the significantly disturbed pathways in alcoholics. Conclusion: Correlation of various metabolites with gut microbiota showed that chronic and moderate dose intake of alcohol decreased the level of Bifidobacterium, Lactobacillus Ruminococcus and Faecalibacterium spp. and increased the levels of Proteobacteria, Alcaligenes and Clostridium.

Syntheses of 1-aryl-5-nitro-1h-indazoles and a general one-pot route to 1-aryl-1h-indazoles

An efficient route to substituted 1-aryl-1H-indazoles has been developed and optimized. The method involved the preparation of arylhydrazones from acetophenone or benzaldehyde substituted by fluorine at C2 and nitro at C5, followed by deprotonation and nucleophilic aromatic substitution (SNAr) ring closure in 45?90%. Modification of this procedure to a one-pot domino process was successful in the acetophenone series (73?96%), while the benzaldehyde series (63?73%) required a step-wise addition of reagents. A general one-pot protocol for 1-aryl-1H-indazole formation without the limiting substitution patterns required for the SNAr cyclization has also been achieved in 62?78% yields. A selection of 1-aryl-1H-indazoles was prepared in high yield by a procedure that requires only a single laboratory operation.

Prospective acetylcholinesterase inhibitory activity of indole and its analogs

Acetylcholinesterase (AChE) inhibitory activity is one of the proposed targets for indole analogs. Simple indoles with substitution of methoxy, carboxy or hydroxy at the benzene ring showed a low percent of inhibitory activity in eel-AChE. Adding a side chain at the pyrrole ring, such as serotonin, beta-carbolines and quinolines (the bioisostere of indole), improved the inhibitory activity significantly. However, proper substitution and conformation of the ring were required for good binding. The result of inhibition in human-AChE of serotonin, beta-carbolines and quinolines showed similar profile as eel-AChE with lower magnitude. The data from molecular docking showed that they shared the same binding site as galantamine.

Revisiting the beta-lactams for tuberculosis therapy with a compound-compound synthetic lethality approach

The suboptimal effectiveness of beta-lactam antibiotics against Mycobacterium tuberculosis has hindered the utility of this compound class for tuberculosis treatment. However, the results of treatment with a second-line regimen containing meropenem plus a beta-lactamase inhibitor were found to be encouraging in a case study of extensively drug-resistant tuberculosis (M. C. Payen, S. De Wit, C. Martin, R. Sergysels, et al., Int J Tuberc Lung Dis 16:558-560, 2012, https://doi.org/10.5588/ijtld.11.0414). We hypothesized that the innate resistance of M. tuberculosis to beta-lactams is mediated in part by noncanonical accessory proteins that are not considered the classic targets of beta-lactams and that small-molecule inhibitors of those accessory targets might sensitize M. tuberculosis to beta-lactams. In this study, we screened an NIH small-molecule library for the ability to sensitize M. tuberculosis to meropenem. We identified six hit compounds, belonging to either the N-arylindole or benzothiophene chemotype. Verification studies confirmed the synthetic lethality phenotype for three of the N-arylindoles and one benzothiophene derivative. The latter was demonstrated to be partially bioavailable via oral administration in mice. Structure-activity relationship studies of both structural classes identified analogs with potent antitubercular activity, alone or in combination with meropenem. Transcriptional profiling revealed that oxidoreductases, MmpL family proteins, and a 27-kDa benzoquinone methyltransferase could be the targets of the N-arylindole potentiator. In conclusion, our compound-compound synthetic lethality screening revealed novel small molecules that were capable of potentiating the action of meropenem, presumably via inhibition of the innate resistance conferred by beta-lactam accessory proteins. beta-Lactam compound-compound synthetic lethality may be an alternative approach for drug-resistant tuberculosis.

Detosylative (Deutero)alkylation of Indoles and Phenols with (Deutero)alkoxides

An efficient strategy for N/O-(deutero)alkylation of indoles and phenols with alkoxides/alcohols as the alkylation reagents is described. The consecutive detosylation/alkylation transformations feature mild reaction conditions, high ipso-selectivity, and good functional group tolerance (>50 examples). A one-pot selective N-alkylation of unprotected indoles with alcohols and TsCl is also realized. The application of this method is demonstrated by the introduction of isotope-labeled (CD3 and 13CH3) groups using the readily accessible labeled alcohols and the synthesis of pharmaceuticals.

Bioactive secondary metabolites with multiple activities from a fungal endophyte

In order to replace particularly biohazardous nematocides, there is a strong drive to finding natural product-based alternatives with the aim of containing nematode pests in agriculture. The metabolites produced by the fungal endophyte Fusarium oxysporum 162 when cultivated on rice media were isolated and their structures elucidated. Eleven compounds were obtained, of which six were isolated from a Fusarium spp. for the first time. The three most potent nematode-antagonistic compounds, 4-hydroxybenzoic acid, indole-3-acetic acid (IAA) and gibepyrone D had LC50 values of 104, 117 and 134?mug?ml?1, respectively, after 72?h. IAA is a well-known phytohormone that plays a role in triggering plant resistance, thus suggesting a dual activity, either directly, by killing or compromising nematodes, or indirectly, by inducing defence mechanisms against pathogens (nematodes) in plants. Such compounds may serve as important leads in the development of novel, environmental friendly, nematocides.
