Oxidation of odor compound indole in aqueous solution with ferrate (VI): Kinetics, pathway, and the variation of assimilable organic carbon

Indole is a typical fecal odor compound and has negative impact on water quality at low concentrations. Here, the oxidation of indole by ferrate [Fe(VI)] was investigated, in terms of the reaction kinetics, the oxidation products, and the variation of assimilable organic carbon (AOC). The oxidation of indole was pH-dependent (6.0-9.5), and the pH-dependent profile could be well explained by the acid-base equilibrium of Fe(VI). The apparent second-order rate constants (k(app)) for indole oxidation with Fe(VI) ranged from 692 +/- 26 M-1 s(-1) at pH 6.0 to 3.08 +/- 0.15 M-1 s(-1) at pH 9.5. The results of experiments conducted under real source water background showed that indole could be effectively removed by Fe(VI) from actual polluted waters. After analyzing the reaction pathway, it was found that the initial steps in the oxidation of indole were the hydroxylation of indole to 2,3-dihydroxyindole, followed by the cleavage of N-heterocyclic ring. Formanilide was a major oxidation product in this process, and it is less reactive with Fe(VI) than that of indole. High concentrations of Fe(VI) could effectively oxidize indole in the water and has little impact on the microbiological stability of the treated water. Based on the results, Fe(VI) can be an effective agent for the control of indole in water treatment.

Nonlinear optical responses of organic based indole derivative: An experimental and computational study

The nonlinear optical (NLO) properties of the Indole-7-carboxyldehyde (I7C) have been investigated by computational and experimental (UV-VIS, Raman) data analysis. Mulliken charge analysis, molecular electrostatic potential, and UV-VIS absorption and vibrational Raman studies have been used to analyze the intra-molecular charge transfer occurrence in the probe system. Observed high value of dipole moment, linear polarizability and first order hyperpolarizability values suggest that the indole derivative may indeed have possibility to show good NLO behaviour.

Synthesis of indole-2-carbohydrazides and 2-(indol-2-yl)-1,3,4-oxadiazoles as antioxidants and their acetylcholinesterase inhibition properties

A range of novel 4,6-dimethoxy-1H-indole-2-carbohydrazides was prepared starting from methyl 4,6-dimethoxy-1H-indole-2-carboxylate which underwent cyclodehydration to generate the corresponding 2-(indol-2-yl)-1,3,4-oxadiazole scaffolds in the presence of N,N-diisopropylethylamine and p-toluenesulfonyl chloride in acetonitrile. All novel compounds were fully characterized by H-1 NMR, C-13 NMR, FT-IR, and high-resolution mass spectroscopic data. Biological importance of the designated compounds was identified by employing three different antioxidant property determination assays, namely DPPH free radical scavenging, ABTS cationic radical decolarization, and cupric reducing antioxidant capacity (CUPRAC). The anticholinesterase properties were also evaluated by the acetylcholinesterase and butyrylcholinesterase enzyme inhibition assays. According to the results, the indole compounds possessing carbohydrazide functionality were found to be more promising antioxidant targets than the 2-(indol-2-yl)-1,3,4-oxadiazole systems. N’-Benzoyl-4,6-dimethoxy-1H-indole-2-carbohydrazide, a member of the dimethoxyindole-2-carbohydrazide group, demonstrated a better inhibition performance than the standards. Additionally, extremely important results were obtained in the anticholinesterase enzyme inhibition assays in the case of 2-(indol-2-yl)-1,3,4-oxadiazole derivatives. [GRAPHICS] .

Divergent Coupling of Benzocyclobutenones with Indoles via C-H and C-C Activations

Highly selective divergent coupling reactions of benzocyclobutenones and indoles, in which the chemoselectivity is controlled by catalysts, are reported herein. The substrates undergo C2(indole)-C8(benzocyclobutenone) coupling to produce benzylated indoles and benzo[b]carbazoles in the Ni- and Ru-catalyzed reactions. A completely different selectivity pattern C2(indole)-C2(benzocyclobutenone) coupling to form arylated indoles is observed in the Rh-catalyzed reaction. Preliminary mechanistic studies suggest C-H and C-C activations in the reaction pathway. Synthetic utility of this protocol is demonstrated by the selective synthesis of three different types of carbazoles from the representative products.

Nickel-Catalyzed trans-Carboamination across Internal Alkynes to Access Multifunctionalized Indoles

A Ni-catalyzed reaction was developed for the synthesis of multifunctionalized indoles. The reaction proceeded through oxidative cyclization of the Ni(0)/P<^>N complex with an enyne system, 2-alkynyl anilinoacrylate, to provide a nickelacycle intermediate. The trans-carboamination around the internal alkyne was achieved by syn/anti-rotation of the Ni-carbenoid intermediate formed by C-N bond cleavage of the nickelacycle, and 3-alkenylated indoles were formed by C-N bond-forming reductive elimination. Notably, the synthesized indoles could be successfully transformed to functionalized carbazoles.

Meroterpenoids produced by fungi: Occurrence, structural diversity, biological activities, and their molecular targets

Meroterpenoids are partially derived from the terpenoids, distributing widely in the plants, animals and fungi. The complex structures and diverse bioactivities of meroterpenoids have attracted more attention for chemists and pharmacologists. Since the first review summarized by Geris in 2009, there are absent of systematic reviews reported about meroterpenoids from the higher and lower fungi up to now. In the past decades, myriads of meroterpenoids were discovered, and it is necessary to summarize these meroterpenoids about their unique structures and promising bioactivities. In this review, we use a new classification method based on the non-terpene precursors, and also highlight the structural features, bioactivity of natural meroterpenoids from the higher and lower fungi covering the period of September 2008 to February 2020. A total of 709 compounds were discussed and cited the 182 references. Meanwhile, we also primarily summarize their occurrence, structural diversity, biological activities, and molecular targets.

Alkaloids with Anti-Onchocercal Activity from Voacanga africana Stapf (Apocynaceae): Identification and Molecular Modeling

A new iboga-vobasine-type isomeric bisindole alkaloid named voacamine A (1), along with eight known compounds-voacangine (2), voacristine (3), coronaridine (4), tabernanthine (5), iboxygaine (6), voacamine (7), voacorine (8) and conoduramine (9)-were isolated from the stem bark of Voacangaafricana. The structures of the compounds were determined by comprehensive spectroscopic analyses. Compounds 1, 2, 3, 4, 6, 7 and 8 were found to inhibit the motility of both the microfilariae (Mf) and adult male worms of Onchocerca ochengi, in a dose-dependent manner, but were only moderately active on the adult female worms upon biochemical assessment at 30 mu M drug concentrations. The IC50 values of the isolates are 2.49-5.49 mu M for microfilariae and 3.45-17.87 mu M for adult males. Homology modeling was used to generate a 3D model of the O. ochengi thioredoxin reductase target and docking simulation, followed by molecular dynamics and binding free energy calculations attempted to offer an explanation of the anti-onchocercal structure-activity relationship (SAR) of the isolated compounds. These alkaloids are new potential leads for the development of antifilarial drugs. The results of this study validate the traditional use of V. africana in the treatment of human onchocerciasis.
