In view of known antitumor and cytotoxic properties of 2- and 3-pyridinyl substituted indole derivatives, respectively a number of isomeric N-pyridinyl substituted indoles and their analogs were synthesized as potential cytotoxic agents. A greener approach was developed to synthesize these compounds via an ultrasound assisted selective N – 1 heteroarylation of indoles. The methodology involved reaction of indoles with heteroaryl halides in PEG-400 under ultrasound irradiation. One of the products i.e. 1-(pyrimidin-2-yl)-1H-indole was further functionalized via Pd-mediated CAH activation at C-2 on the indole ring. All the synthesized N – 1 heteroarylindoles were tested for their in vitro anti-proliferative properties against cancer (leukemia) and non-cancerous cell lines. Some of the compounds showed promising and selective cytotoxic effects toward leukemia cells. (C) 2015 King Saud University. Published by Elsevier B.V.

Readily prepared 3-(2-aminoaryl)-6-aminopyridazine N-oxides undergo a photoinduced cascade transformation to furnish 1H-indole-2-acetamides. The reported method uniquely proceeds via acid-catalyzed isomerization of a 2-aminofuran intermediate and supports modular synthetic entry to indole derivatives that would be difficult to access by any other means.

Arthrobacter pascens ZZ21 is a plant-beneficial, fluoranthene-degrading bacterial strain found in the rhizosphere. The production of the phytohormone indole-3-aectic acid (IAA) by ZZ21 is thought to contribute to its ability to promote plant growth and remediate fluoranthene-contaminated soil. Using genome-wide analysis combined with metabolomic and high-performance liquid chromatography-mass spectrometry (HPLC-MS) analyses, we characterized the potential IAA biosynthesis pathways in A. pascens ZZ21. IAA production increased 4.5-fold in the presence of 200 mgL(-1) tryptophan in the culture medium. The transcript levels of prr and aldH, genes which were predicted to encode aldehyde dehydrogenases, were significantly upregulated in response to exogenous tryptophan. Additionally, metabolomic analysis identified the intermediates indole-3-acetamide (IAM), indole-3-pyruvic acid (IPyA), and the enzymatic reduction product of the latter, indole-3-lactic acid (ILA), among the metabolites of ZZ21, and subsequently also IAM, ILA, and indole-3-ethanol (TOL), which is the enzymatic reduction product of indole-3-acetaldehyde, by HPLC-MS. These results suggest that the tryptophan-dependent IAM and IPyA pathways function in ZZ21.

In this work, the effect of ultrasound irradiation on the catalytic oxidative/adsorptive denitrogenation (COADN) of model hydrocarbon fuels (composed of pyrrole or indole as an organonitrogen compounds dissolved in n-nonane) has been investigated using magnetic reduced graphene oxide supported with phosphomolybdic acid (PMo-Fe3O4/rGO) as a heterogeneous catalyst/adsorbent and hydrogen peroxide as an oxidant. The synthesized PMo-Fe3O4/rGO nanocomposite was characterized by XRD, FE-SEM, VSM and BET surface area analysis methods. Moreover, different experimental variables including catalyst dose, initial pyrrole/indole concentration, H2O2 to pyrrole/indole molar ratio, ultrasound power and sonication time have been studied on the COADN process. The regeneration/recyclability of PMo-Fe3O4/rGO catalyst was also examined. Experimental results revealed that, the ultrasound treatment significantly improved the adsorption process of organonitrogen compounds from model fuels (q(e) increased by 50.3% for pyrrole and 18% for indole). Furthermore, high ultrasound-aided catalytic oxidative denitrogenation efficiency (85.6% for pyrrole and 90% for indole) has been attained under optimal conditions (ultrasonic power = 200 W, sonication time = 240 min, catalyst dose = 2 g/L, and H2O2:pyrrole/indole molar ratio = 5). The recyclability of catalyst displayed that the prepared catalyst can be reused five times without any significant reduction in its performance.

A mild, reductive spirocyclization of indole-linked amides and lactams for the efficient and selective synthesis of aza-spirocyclic indoline products is described. The catalytic reductive activation of tertiary amides or lactams by Vaska’s complex with tetramethyldisiloxane as the terminal reductant allowed iminium ion formation, before a diastereoselective 5-endo-trig spirocyclization of the tethered indole moiety was triggered. Terminal reduction affords the aza-spiroindoline products in an overall highly chemoselective and diastereoselective one-pot process.

The intestinal epithelium is a highly dynamic structure that rejuvenates in response to acute stressors and can undergo alterations in cellular composition as animals age. The microbiota, acting via secreted factors related to indole, appear to regulate the sensitivity of the epithelium to stressors and promote epithelial repair via IL-22 and type I IFN signaling. As animals age, the cellular composition of the intestinal epithelium changes, resulting in a decreased proportion of goblet cells in the colon. We show that colonization of young or geriatric mice with bacteria that secrete indoles and various derivatives or administration of the indole derivative indole-3 aldehyde increases proliferation of epithelial cells and promotes goblet cell differentiation, reversing an effect of aging. To induce goblet cell differentiation, indole acts via the xenobiotic aryl hydrocarbon receptor to increase expression of the cytokine IL-10. However, the effects of indoles on goblet cells do not depend on type I IFN or on IL-22 signaling, pathways responsible for protection against acute stressors. Thus, indoles derived from the commensal microbiota regulate intestinal homeostasis, especially during aging, via mechanisms distinct from those used during responses to acute stressors. Indoles may have utility as an intervention to limit the decline of barrier integrity and the resulting systemic inflammation that occurs with aging.

Catalytic amounts of B(C6F5)(3) was found to be able to catalyze the highly regioselective addition of various indoles to phenylacetylene, and produced different substituted bisindolylmethanes in high yields at room temperature. Contrast to the traditional catalysts such as In, Pt and Ru, (C6F5)(3) finished the reaction under green and mild catalytic conditions with high atom economical and good functional group tolerance. Under the optimization reaction conditions, near quantitative conversions and up to 92% yields of bisindolylmethanes were achieved. According to the separated byproduct 4a’ and the observed intermediates I, a possible reaction mechanism based on the mechanistic studies has been proposed. The reaction was initiated from the activation of phenylacetylene by (C6F5)(3) and ended with the addition of two molecules indoles one by one to the phenylacetylene. The further applied value research of bisindolylmethanes is in progress.

Method for the determination of two auxins, indole-3-acetic acid and indole-3-butyric acid, is developed using HPLC with electrochemical detection. As the working electrode, recently developed carbon felt detector with high conversion degree was employed. Optimum conditions, i.e. separation on 125-4 Lichrospher 100, RP-18 column with mobile phase consisting of buffer pH 4.0 and methanol (40:60, v/v) and detection at potential +1.5V, allow to obtain linear concentration dependences in the concentration range from 1 to 100 mu moldm(-3), with determination limits of 1.1 mu moldm(-3) and 1.8 mu moldm(-3) for indole-3-acetic and -butyric acid, respectively. Applicability of the method was verified by the determination of both analytes in rooting preparation; the results were in agreement with the reference method, although not with the values declared by the manufacturer.
