Here, we have developed a 3-component one-pot sequential approach to 3-substituted indoles. The main advantages of this process are step economy, reduced waste, and operational simplicity. The method involves in situ generation of 3-indolylalcohols from the reaction of indoles and aldehydes in the presence of base. Further, nucleophilic substitution of 3-indolylalcohols with various nucleophiles affords 3-substituted indole derivatives. The reaction does not requires any hazardous and expensive metal catalyst. In addition, the reaction is carried out in (1:1) ethanol-water which is considered as environmentally benign solvent. On the other hand, nonsequential 3-component reaction results in the formation of unwanted bisindolylmethanes. [GRAPHICS] .

The symbiotic interaction between rhizobia and legumes that leads to nodule formation is a complex chemical conversation involving plant release of nod-gene inducing signal molecules and bacterial secretion of lipo-chito-oligossacharide nodulation factors. During this process, the rhizobia and their legume hosts can synthesize and release various phytohormones, such as IAA, lumichrome, riboflavin, lipo-chito-oligossacharide Nod factors, rhizobitoxine, gibberellins, jasmonates, brassinosteroids, ethylene, cytokinins and the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase that can directly or indirectly stimulate plant growth. Whereas these attributes may promote plant adaptation to various edapho-climatic stresses including the limitations in nutrient elements required for plant growth promotion, tapping their full potential requires understanding of the mechanisms involved in their action. In this regard, several N-2-fixing rhizobia have been cited for plant growth promotion by solubilizing soil-bound P in the rhizosphere via the synthesis of gluconic acid under the control of pyrroloquinoline quinone (PQQ) genes, just as others are known for the synthesis and release of siderophores for enhanced Fe nutrition in plants, the chelation of heavy metals in the reclamation of contaminated soils, and as biocontrol agents against diseases. Some of these metabolites can enhance plant growth via the suppression of the deleterious effects of other antagonistic molecules, as exemplified by the reduction in the deleterious effect of ethylene by ACC deaminase synthesized by rhizobia. Although symbiotic rhizobia are capable of triggering biological outcomes with direct and indirect effects on plant mineral nutrition, insect pest and disease resistance, a greater understanding of the mechanisms involved remains a challenge in tapping the maximum benefits of the molecules involved. Rather than the effects of individual rhizobial or plant metabolites however, a deeper understanding of their synergistic interactions may be useful in alleviating the effects of multiple plant stress factors for increased growth and productivity.

Nitidine chloride (NC) possesses anticancer properties in various types of human malignancies. However, the effects of NC on lung cancer cells have not been elucidated. Moreover, the molecular mechanism of NC-involved antitumor activity is unclear. Therefore, we aimed to determine the biological effect of NC and the underlying molecular insights in lung cancer cells. The antineoplastic function of NC was assessed by MTT assays, Annexin VFITC/PI apoptosis assay, wound healing analysis, and Transwell chamber migration and invasion assay in lung cancer cells. NEDD4 modulation was evaluated by western blotting assays of lung cancer cells after NC treatments. NEDD4 overexpression and downregulation were employed to validate the critical role of NEDD4 in the NC-mediated tumor suppressive effects. We found that NC suppressed cell viability, migration and invasion, but induced apoptosis in lung cancer cells. Mechanistic exploration revealed that NC exhibited its antitumor effects by reducing NEDD4 expression. Furthermore, our rescue experiments dissected that overexpression of NEDD4 abrogated the NC-mediated antineoplastic effects in lung cancer cells. Consistently, downregulation of NEDD4 enhanced the NC-induced anticancer effects. Thus, NC is a promising antitumor agent in lung cancer, indicating that NC might have potential therapeutic applications in the treatment of lung cancer.

Indole is a volatile compound and emitted from plants challenged by insect infestation or mechanic wounding. It has been shown to prime defense against herbivory. Here we identified that indole induced defense either directly or as a priming agent against necrotrophic pathogens Fusarium graminearum and F. moniliforme in maize and Magnaporthe oryzae in rice. With indole pretreatment, smaller lesions were developed in infected leaves, as well as less fungal growth. Indole induced H2O2 burst in the priming stage like other priming substances did. Such priming relied on mitogen-activated protein kinase (MAPK) cascade, which potentially activated downstream defense signaling. In addition, indole priming resulted in earlier and stronger defensive gene expression upon pathogen infection, including genes of jasmonate and phytoalexin biosynthesis, pathogenesis-related proteins (PRs) and anti-oxidant enzymes, which enhanced plant resistance. Meanwhile, H2O2 was also identified as the priming agent to induce plant defense. Taken together, indole exhibited priming function not only against herbivory but also necrotrophic pathogens. The common emission of indole in plants suggests that it plays important roles as the universal and endogenous priming substance in plant defense.

The B-BOX (BBX) proteins are an important class of zinc-finger transcription factors involved in the regulation of plant growth and development, and have been identified in many plant species. However, there is no systematic study of common wheat (Triticum aestivum L.) BBX genes. Through comprehensive bioinformatics analysis, we identified and characterised 96 BBX genes from wheat, and provided the genes with a unified nomenclature. We describe the chromosomal location, gene structure, conserved domains, phylogenetic relationships and promoter cis-elements of TaBBX family members. The expression patterns under different conditions, especially under different hormones and light-dark conditions, were studied in detail. According to the diversity of conserved domains, we divided TaBBX proteins into five subfamilies. Gene-duplication analysis showed that duplication of chromosome segments was the main reason for the expansion of the TaBBX gene family. Detecting the expression profiles of six TaBBX genes in different tissues by quantitative real-time PCR, we found that the six genes are regulated under light-dark treatment, and that some TaBBX genes (TaBBX2.11, TaBBX2.13, TaBBX2.15 and TaBBX3.10) are strongly induced by the plant hormones abscisic acid, indole-3-acetic acid and salicylic acid. Our analysis of wheat BBX genes at the genomic level will provide a solid foundation for further identifying the functions of specific genes in light stress responses.

Enzymatic hydrolysis of indole glucosinolates in the human body yields the Indole-3-carbinol family of compounds (I3Cs). I3Cs are implicated in the self-healing processes of the human body and thus used as over the counter dietary supplements characterized as potential antioxidants. In this study, the antioxidant activity of natural indole-3-carbinol derivatives were investigated against the HOO center dot radical by using thermodynamic and kinetic calculations. It was found that natural I3Cs containing only C8-H and/or N1-H bonds such as indole-3-carbinol, 4-methoxy-indole-3-carbinol, and 1-methoxy-indole-3-carbinol exhibit weak antioxidant properties. However, the presence of OH groups in the indole ring significantly increases the radical scavenging in aqueous as well as lipid media. In particular the HOO center dot scavenging activity of 1-hydroxyl-indole-3-carbinol far exceeds that of Trolox, 2.0 times in aqueous medium and 352.9 times in lipid (pentyl ethanoate) medium. This suggests that 1-hydroxyl-indole-3-carbinol is one of the most powerful known antioxidants in lipid environments, pointing at potential dietary application in preventive and regenerative medicine.

N-Arylindoles are transformed into dihydroacridines in a new type of rearrangement, through heating with triethylsilane and potassium tert-butoxide. Studies indicate that the pathway involves (i) the formation of indole radical anions followed by fragmentation of the indole C2-N bond, and (ii) a ring-closing reaction that follows a potassium-ion dependent hydrogen atom transfer step. Unexpected behaviors of ‘radical-trap’ substrates prove very helpful in framing the proposed mechanism.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
