Divergent Functionalization of N-Alkyl-2-alkenylanilines: Efficient Synthesis of Substituted Indoles and Quinolines

An efficient divergent functionalization of N-alkylated ortho-alkenylanilines to substituted indoles and quinolines has been accomplished by employing rhodium-catalyzed cross-dehydrogenative coupling and silver-mediated oxidative cyclization, respectively. The developed methods tolerate various functional groups and allow the synthesis of substituted indoles and quinolines in good to excellent yield. Synthetic utility is demonstrated through conversion to an indole with antimicrobial activity and C-H bond functionalization of 2-arylquinolines. Furthermore, a plausible mechanism was proposed based on preliminary mechanistic investigations.

Micropropagation through indirect organogenesis in Solanum capsicoides All., and assessment of clonal fidelity using ISSR markers

Solanum capsicoides All., is an important medicinal plant which is used as a source of ‘Kantakari’ (medicine for phlegm disorders) in India. The restricted distribution of the plant in Kerala along with its overexploitation necessitates the development of a protocol for in vitro propagation of S. capsicoides. The present study reports the effects of four different cytokinins (2 isopentenyl adenine (2iP), benzyl adenine (BAP), kinetin (KIN), and zeatin (ZEA)) in combination with indole 3-butyric acid (IBA) on indirect organogenesis of S. capsicoides from in vitro grown seedling explants such as cotyledon, shoot tip, and hypocotyl. Maximum shoot development was observed from cotyledon explants inoculated on MS medium supplemented with 2.46 mu M IBA and 4.56 mu M ZEA. An average of 17 +/- 0.5 shoots per cotyledon with an average length of 0.53 +/- 0.03 cm was observed. After subculture, an average of 20 +/- 1 shoots was observed in cotyledon explants inoculated on Murashige and Skoog medium supplemented with 2.46 mu M IBA and 6.84 mu M ZEA. Clonal fidelity of regenerated plants was confirmed using DNA based molecular marker, intersimple sequence repeat (ISSR). Clonal fidelity test revealed 0% polymorphism and the PIC value 0 which indicate no diversity from seed-borne plants. The protocol thus developed can be used for rapid multiplication and conservation of S. capsicoides.

Removal of both basic and non-basic N-compounds from diesel fuel with deep eutectic solvent

Deep eutectic solvent (DES) tetraethyl ammonium bromide-malonic acid (TEAB-Mal) was synthesized and its structure was characterized with FTIR spectroscopy. The denitrogenation performance of the solvent was investigated using model diesel fuel containing quinoline or indole. Experiment results showed that the removal efficiencies of quinoline and indole were 97.7 and 90.1% at temperature of 30 degrees C, 1:7 (w/w) DES: oil, extraction time of 30 min, respectively. In addition, the quinoline and indole removal efficiencies can still reach 86.4 and 78.9% after four recycles of the DES, respectively.

Alcaligenes aquatilis GTE53: Phosphate solubilising and bioremediation bacterium isolated from new biotope phosphate sludge enriched-compost

The isolation and identification of beneficial bacteria from the active phase of composting is considered to be a key bio-quality parameter for the assessment of the process. The aim of this work was the selection and identification of beneficial bacteria from a co-composting experiment of vegetable waste (VW), olive oil mill waste (O2MW), and phosphate sludge (PS). Phosphate-solubilizing strains were isolated from the thermophilic phase using Pikovskaya (PVK) solid medium supplemented with tricalcium phosphate Ca-3 (PO4) (TCP) as the sole source of phosphorus (P). Therefore, the selected isolate Alcaligenes aquatilis GTE53 was tested to tolerate abiotic stresses (different levels of temperature, variable pH, high salinity and water stress). The isolate was also assessed for indole acetic acid (IAA) and siderophores synthesis, nitrogen fixation, phenol degradation and pathogens inactivation. The quality of the co-composting process was also investigated by monitoring the physico-chemical parameters. The obtained results showed that A. aquatilis GTE53 displayed a higher solubilization index of 2.4 and was efficiently dissolved, up to 162.8 and 247.4 mg.mL(-1) of inorganic phosphate from PS and phosphate rock (PR), respectively. A. aquatilis GTE53 exhibited siderophores and IAA release, along with atmospheric nitrogen fixation. In addition to that, A. aquatilis GTE53 showed a high resistance to heat and tolerance to acidic and alkaline pH, high salinity and water stress. Moreover, A. aquatilis GTE53 could degrade 99.2% of phenol from a high concentrated medium (1100 mg.L-1 of phenol) and can inactivate the most abundant pathogens in industrial wastes: Escherichia coli, Streptococcus sp., Salmonella sp., and Fusarium oxysporum albedinis. Analysis of temperature, pH, electrical conductivity, carbon/nitrogen (C/N) ratio, indicated successful co composting. An efficient transformation of P to the available form and a great abatement of polyphenols, were also recorded during the process. The findings of this study will help to advance the understanding of A. aquatilis GTE53 functions and will facilitate its application to promote beneficial microbial organisms during composting, thus obtaining a high-quality product.

Anthraquinone-containing compound in rhubarb prevents indole production via functional changes in gut microbiota

Indole is produced from dietary tryptophan by tryptophanase in intestinal bacteria, such as Escherichia coli. In the liver, indole is converted into indoxyl sulfate, a uremic toxin and risk factor for chronic kidney disease (CKD). Probiotics and prebiotics are currently used for suppressing CKD, but there are no drugs that directly suppress indole production. In this study, we developed an optimized HPLC method for analyzing indole production and evaluated the effect of diets and rhubarb on indole production via the changes of gut microbiota. In high-carbohydrate and high-fat diet-fed mice, the indole production was significantly higher than in high-fiber diet-fed mice. We further used the high-carbohydrate diet-fed mice as a model for examining the effect of rhubarb on indole production. The 20% methanol-eluted fraction of aqueous rhubarb extract significantly suppressed indole production, and the eluate constituent rhein 8-O-beta-d-glucopyranoside (RG) contributed to this effect in a concentration-dependent manner. The effect of RG depended on the anthraquinone core substructure, i.e., the aglycone moiety (rhein) of RG, which appeared to inhibit the tryptophanase function in gut microbiota. Thus, in addition to earlier reports that rhubarb is an effective CKD treatment, our study demonstrated that the anthraquinone moiety in rhubarb prevents uremic toxin production via functional changes in gut microbiota, which suppresses CKD progression.

Exploring the scope of indole interaction with 1,2-dicarbonyl compounds

The 1,2-dicarbonyl compounds have received extensive attention due to their high reactivity and toxicity in vitro and in vivo. Availability of scavenging compounds may facilitate development of efficient strategies for their control. The concept of in situ generation of carbonyl trapping agents is an intriguing proposition and has been demonstrated with amino acid tryptophan. Ability of indole to undergo electrophilic aromatic substitution reaction was studied in the past with methylglyoxal. To confirm the generality of this reaction, model systems containing indole and several 1,2-dicarbonyl compounds were prepared and reacted at room temperature (RT) and at 150 degrees C and analyzed by ESI-qTOE-MS/MS and isotopic labeling technique. Indole showed ability to capture all the tested 1,2-dicarbonyls. Longer chain 1,2-dicarbonyls showed higher temperature dependency than shorter chain in their reactivity towards indole. Furthermore, the ability of indole to scavenge Strecker aldehydes was also demonstrated in alanine/glucose and in a bread model systems using [C-13-2]indole.

Regio and Enantioselective Organocatalytic Friedel-Crafts Alkylation of 4-Aminoindoles at the C7-Position

A chiral phosphoric acid catalyzed highly regio- and enantioselective Friedel-Crafts alkylation at the indole C7-position was developed via the introduction of an alkylamine moiety at the C4-position of the indole ring. The methodology is applicable to a wide range of 4-aminoindoles and beta,gamma-unsaturated alpha-ketimino esters to furnish the corresponding C7-position functionalized chiral indole derivatives in high yields with moderate to excellent enantioselectivities. Furthermore, the alpha-ketimino ester moiety in the products is a versatile building block and enables many further transformations.

Assessing of growth, antioxidant enzymes, and phytohormone regulation in Cucurbita pepo under cadmium stress

One of the major problems worldwide is soil pollution by trace metal elements, which limits plant productivity and threatens human health. In this work, we have studied the effect of different concentrations of cadmium on Cucurbita pepo plants, evaluating different physiological and biochemical parameters: hormone signaling, metabolite concentration (malondialdehyde and hydrogen peroxide) and, in addition, the antioxidant enzyme activities of catalase and superoxide dismutase were evaluated. The production of biomass decreased under the Cd-stress. The results showed that C. pepo accumulates higher amounts of Cd2+ in roots than in shoots and fruits. Cd2+ differently affected the content of endogenous phytohormones. Furthermore, data suggest an essential involvement of roots in the regulation of tolerance to trace elements. As a result, indole acetic acid content increased in roots of treated plants, indicating that this phytohormone can stimulate root promotion and growth under Cd-stress. Similarly, salicylic acid content in roots and shoots increased in response to Cd2+, as well as abscisic acid levels in roots and fruits. In roots, the rambling accumulation pattern observed for jasmonic acid and salicylic acid suggests the lack of a specific regulation role against trace element toxicity. The activity of catalase and superoxide dismutase decreased, disrupted by the metal stress. However, the proline, malondialdehyde and hydrogen peroxide content significantly increased in Cd(2+)in all the analyzed tissues of the stressed plants. All these data suggest that C. pepo plants are equipped with an effective antioxidant mechanism against oxidative stress induced by cadmium up to a concentration of 500 mu M.
