BACKGROUND Indole, an important type of N-heterocyclic aromatic compound, is considered a toxic and odorous pollutant in coking and municipal wastewater. For efficient bioremediation of indole-containing wastewater, an indole-degrading bacterial strain JW was isolated from activated sludge in this study. The indole biodegradation characteristics and the whole-genome sequence of strain JW were also determined. RESULTS Strain JW, capable of utilizing indole as the sole carbon and nitrogen source, was identified as Acinetobacter sp. based on 16S rRNA gene sequence analysis. It was able to completely degrade 100 mg L-1 indole within 20 h, and transform organic nitrogen to ammonia (NH4+-N) and nitrate (NO3–N). Meanwhile, strain JW also presented high capacity for indole degradation at a range of initial indole concentrations (25-200 mg L-1) and pH (6.0-8.0). The key metabolites during indole biodegradation were identified by liquid chromatography coupled to Q-Exactive high resolution mass spectrometry, and included isatin, anthranilate, salicylate, catechol and indigo. The whole-genome sequence of strain JW revealed the possible functional genes related to indole biodegradation, such as iif genes, ant genes and downstream metabolic genes. Thus, an indole biodegradation mechanism was proposed based on metabolites identification and genomic analysis. CONCLUSION The results suggested that Acinetobacter sp. JW could be a promising biological candidate for bioremediation of indole, and the useful genetic information might enrich our understanding of microbial degradation of indole.

The C-C ring closure of alpha-chloromethyl alkyl or aryl N-aryl imines catalyzed with 1 to 10 % Pd(OAc)(2)/P(p-tolyl)(3) afford efficiently 2-aryl- and 2-alkyl-1H-indoles. The heterocyclization reaction involves the initial formation of [2-(arylimino)ethyl]palladium(II) chloride complexes with subsequent C-H activation of the aromatic amine ring. Readily or commercially available alpha-chloromethyl-aryl or -alkyl ketones are used as the precursors. Functionalized indoles at the benzene ring are obtained when the imines are derived from substituted anilines.

Indole derivatives are important heterocycles in organic synthesis for serving as privileged building blocks for functional material and as key components in a lot of bioactive compounds. Propargylic alcohols, bearing alkynyl and hydroxyl functional groups, have emerged as promising feedstock materials for the construction of carbo- and heterocycles. Especially, in the last decade, the Lewis or Bronsted acid catalysed tandem annulations of propargylic alcohols to build structurally diverse indole derivatives have been well-investigated. In this review, we summarize two main synthetic strategies toward indole derivatives via the cascade reactions of propargylic alcohols: indole-ring formation involved tandem reactions and the direct function-alization of indole skeletons. We hope this review would help to develop new and more efficient protocols for the synthesis of indole-included N-heterocycles.

An organocatalytic asymmetric arylmethylation/N-hemiacetalization of 2-indolyl methane derivatives and 2-enals was developed. Notably, the 2-methyl of indole was readily deprotonated to produce highly reactive nucleophilic species by introducing the nitro group at the C3 position of the indole ring. A spectrum of valuable chiral dihydropyrido[1,2-a]indoles were efficiently constructed with excellent enantioselectivity (up to >99% ee). Furthermore, the corresponding products could be easily functionalized via simple deprotonation and treatment with other electrophiles with excellent diastereoselectivities (>20:1 dr).

The dispersed on mesoporous SBA-15 has demonstrated the regioselective C-H bond C-3-cyanation of indoles by in-situ generation of -CN using DMF and NH4I in presence of O-2. Pyridine adsorbed diffuse reflectance infrared spectroscopy (DRIFTS) results revealed that surface Cu2+ species are acting as Lewis acid sites in the in-situ generation of cyano-group for the synthesis of indole nitriles. A direct correlation between Cu metal surface area and the indole nitrile yields are established and the dual role of copper is substantiated by N2O titration and XPS techniques. The 10 wt%Cu/SBA-15 demonstrated superior performance when compared to Pd, Ru supported on SBA-15. The 10 wt%Cu/SBA-15 catalyst showed consistent activity and selectivity after the 4th cycle.

Acetylenic Indole-Encapsulated Schiff Bases: Synthesis, In Silico Studies as Potent Antimicrobial Agents, Cytotoxic Evaluation and Synergistic Effects

A family of pharmacophore acetylenic indole-3-carboxaldehyde (3) and acetylenic indole schiff bases (5a-5i) bearing indole framework were synthesized to afford structurally diverse moieties. Acetylenic indole-3-carboxaldehyde was coupled with various amines to furnish the novel scaffolds 5a-5i. These acetylenic indole Schiff bases (AISB) were synthesized in shorter times under microwave irradiation in comparison to classical reaction conditions. AISB were experimentally characterized by using IR, (HNMR)-H-1, (CNMR)-C-13, X ray crystallographic and mass spectrometric methods. The synthesized compounds showed promising anti-bacterial and anti-fungal properties when tested invitro against six bacterial and seven fungal strains. Among these, hybrids 5a, 5c, 5e and 5g were found to be even more potent than the standard drugs and were more influential against the bacterial than the fungal strains. These more potent compounds were then evaluated for their cytotoxicity by MTT assay on Hek293 and HeLa cells. The synergistic effect of bis-acetylenic compound 5g with kanamycin and amphotericin B has also been scrutinized. Further, the structural and electronic properties of the molecules were investigated theoretically by performing density functional theory (DFT).

Metal-Catalyzed Synthesis of Substituted Indoles

Indoles are important structural motifs that are commonly found in a diverse array of natural products, pharmaceuticals, and other functional molecules. Consequently, the development of new, more efficient synthetic methods for the construction of substituted indoles continues to be of great importance and considerable interest. Over the past few decades, metal-catalyzed C-C/C-N bond-forming reactions have emerged as a powerful synthetic strategy for heterocyclic synthesis. In this review, we have provided a brief overview of recent advances in the metal-catalyzed synthesis of substituted indoles through the construction of the pyrrole nucleus of indoles, involving the formation of multiple C-C/C-N bonds.

Backpropagation neural networks modelling of photocatalytic degradation of organic pollutants using TiO2-based photocatalysts

BACKGROUND The advanced oxidation process using photocatalysts has been proven to be an efficient technique used for the degradation of organic pollutants in wastewater. However, there exists a nonlinear relationship between the process parameters of the photodegradation reaction, which needs to be well understood for the design of an efficient photoreactor. This study employed a backpropagation artificial neural network (BPANN) for the modelling of photocatalytic degradation of indole, anthraquinone dye and methyl blue using undoped and Ag+-doped TiO2 catalysts. RESULTS A Levenberg-Marquardt algorithm was employed to train the BPANN by varying the hidden neurons to obtained an optimized architecture. Optimized architectures with 3-14-1, 4-12-1 and 3-16-1 consist of the input layers, hidden layer and the output layer, were obtained using the datasets from photodegradation of indole, anthraquinone dye and methyl blue, respectively. The optimized BPANN accurately predicts the indole, anthraquinone dye and methyl blue degradation as a function of colour removal from the wastewater. High coefficients of determination (R-2) of 0.999, 0.961 and 0.993 were obtained for the prediction of the photodegradation of indole, anthraquinone dye and methyl blue, respectively, with over 95% confidence level. The study revealed that dye concentration, catalyst dosage and reaction time have the highest level of importance for the photodegradation of indole, anthraquinone dye and methyl blue, respectively. CONCLUSION This study has demonstrated the robustness of BPANN for predictive modelling of photodegradation of organic pollutants such as indole, anthraquinone dye and methyl blue.
