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.

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.

A triphenylamine-based colorimetric and fluorescent probe with donor-bridge-acceptor structure for detection of G-quadruplex DNA

In this Letter, three triphenylamine-based dyes (TPA-1, TPA-2a and TPA-2b) with donor-bridge-acceptor (D-pi-A) structure were designed and synthesized for the purpose of G-quadruplexes recognition. In aqueous conditions, the interactions of the dyes with G-quadruplexes were studied with the aim to establish the influence of the geometry of the dyes on their binding and probing properties. Results indicate that TPA-2b displays significant selective colorimetric and fluorescent changes upon binding of G-quadruplex DNA. More importantly, its distinct color change enables visual detection and differentiation of G-quadruplexes from single and duplex DNA structures. CD titration date reveals that TPA-2b could induce and stabilize the formation of G-quadruplex structure. All these remarkable properties of TPA-2b suggest that it should have promising application in the field of G-quadruplexes research.

C7-derivatization of C3-alkylindoles including tryptophans and tryptamines

A versatile strategy for C7-selective boronation of tryptophans, tryptamines, and 3-alkylindoles by way of a single-pot C2/C7-diboronation-C2-protodeboronation sequence is described. The combination of a mild iridium-catalyzed C2/C7-diboronation followed by an in situ palladium-catalyzed C2-protodeboronation allows efficient entry to valuable C7-boroindoles that enable further C7-derivatization. The versatility of the chemistry is highlighted by the gram-scale synthesis of C7-boronated N-Boc-L-tryptophan methyl ester and the rapid synthesis of C7-halo, C7-hydroxy, and C7-aryl tryptophan derivatives.
