A novel indole-based conjugated microporous polymer for highly effective removal of heavy metals from aqueous solution via double cation-pi interactions

A novel indole-based conjugated microporous polymer (PTIA) with three coplanar indole units, designed and synthesized by an oxidative coupling reaction, was utilized as a platform for removing heavy metals. Owing to the conjugation of the three coplanar indoles, the highly electron-rich large pi planes can simultaneously attract six heavy metal atoms via double cation-pi interactions, endowing this microporous material with remarkable heavy metal adsorption capacity and efficiency.

Regio- and Enantioselective Friedel-Crafts Benzhydrylation of Indoles in Carbocyclic Ring with ortho-Quinomethanes: Access to Chiral Diarylindolylmethanes

The functionalization of indoles in the carbocyclic ring has been achieved via organocatalytic enantioselective Friedel-Crafts benzhydrylation of hydroxyindoles with in situ generated ortho-quinomethanes in oil-water biphases, allowing an efficient access to varied diarylindolylmethanes with a wide substrate scope. The high yields, excellent stereoselectivities, mild conditions, low catalyst loading, and easy scalability also demonstrated the interest of this novel methodology.

Enhanced in vitro shoot proliferation through nodal explants of Staurogyne repens (Nees) Kuntze

In this study, multiple and rapid propagations of Staurogyne repens (Nees) Kuntze with tissue culture techniques were aimed. The nodal explants of S. repens were cultured for multiple shoot regeneration in culture medium supplemented with different rates of 6-Benzilaminopurin (BAP) and Kinetin (KIN) alone (0.25-1.50 mg/L) or combinations with 0.25 mg/L Indole-3-acetic acid (IAA). Generally, shoot regeneration capabilities of the explants were high due to the growth regulators used. Shoot regeneration frequencies were ranked between 77.77% and 100.00% in BAP-IAA and KIN-IAA applications. In BAP-IAA application, the average number of shoots was recorded between 2.53-16.11 shoots/explant and the highest number of shoots per explant (16.11 shoots/explant) was obtained in culture medium containing 1.25 mg/L BAP. As the BAP level used increased, the number of regenerated shoots increased. In KIN-IAA application, mean shoot counts were recorded as 2.66-10.27 shoots/explant, and maximum shoots per explant (10.27 shoots/explant) was determined in culture medium containing 0.50 mg/L KIN. When shoot lengths were examined, longer shoots were seen in KIN-IAA application compared to BAP-IAA application. The longest shoot was obtained as 2.82 cm in the culture medium fortified with 1.50 mg/L KIN. Regenerated shoots for in vitro rooting were transferred to the growth culture containing different concentrations of IAA and 1-Naphthaleneacetic acid (NAA). The best values in terms of number and length of roots per shoot were determined in a growth culture containing 0.25 mg/L IAA. The rooted shoots were accustomed to external conditions successfully.

Competitive adsorption between sulfur- and nitrogen-containing compounds over NiMoS nanocluster: The correlations of electronegativity, morphology and molecular orbital with adsorption strength

Using combination of density functional theory calculation and dispersion corrections, we try to find the correlation between nature of nitrogen-containing compounds (indole, quinoline, carbazole and acridine) as well as their hydrodenitrogenation intermediates and the adsorption strength of them over multisite NiMoS nanocluster, and to utilize the correlation into the competitive adsorption between N-compounds and S-compounds. The competitiveness of aromatic compounds and HDT by-products are included. The results show the adsorption strength is not only dominant by the electronegativity but also influenced by the morphology of N-compounds and the lowest-unoccupied molecular orbitals of active sites. For multisite NiMoS, the influence of competitive adsorption decreases as Corner approximate to Mo-Edge > S-Edge; for certain N-compound series, almost all the adsorption strength is larger than that of corresponding S-compound. Except for the N-compounds themselves, the potential strong inhibitors should be the partial or fully saturated intermediates as well as ammonia. (C) 2020 Elsevier Ltd. All rights reserved.

Synthesis, Antimicrobial Activity, Structure-Activity Relationship, and Molecular Docking Studies of Indole Diketopiperazine Alkaloids

Strategies for the synthesis of indole diketopiperazine alkaloids (indole DKPs) have been described and involve three analogs of indole DKPs. The antimicrobial activity and structure-activity relationship (SAR) of 24 indole DKPs were explored. Compounds 3b and 3c were found to be the most active, with minimum inhibitory concentrations (MIC) values in the range of 0.94-3.87 mu M (0.39-1.56 mu g/mL) against the four tested bacteria (Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, and Escherichia coli). Furthermore, compounds 4a and 4b displayed broad-spectrum antimicrobial activity with MIC values of 1.10-36.9 mu M (0.39-12.5 mu g/mL) against all tested bacteria and plant pathogenic fungi (Colletotrichum gloeosporioides, Valsa mali, Alternaria alternata and Alternaria brassicae). According to the in silico study, compounds 3c showed significant binding affinity to the FabH protein from Escherichia coli, which has been identified as the key target enzyme of fatty acid synthesis (FAS) in bacteria. Therefore, these compounds are not only promising new antibacterial agents but also potential FabH inhibitors.

Aromatic Aza-Claisen Rearrangement of Arylpropargylammonium Salts Generated in situ from Arynes and Tertiary Propargylamines

The charge-accelerated aza-Claisen rearrangement of ammonium salts serves as a key step in the construction of complex nitrogen-containing molecules. However, much less attention has been paid to the aromatic aza-Claisen rearrangement than to the aliphatic one. Herein, we report an unprecedented aromatic aza-Claisen rearrangement of arylpropargylammonium salts, generated in situ from arynes and tertiary propargylamines, delivering structurally diverse 2-propargylanilines in moderate to good yields with high regioselectivity. This rearrangement proceeds in the absence of strong bases or transition metals, is compatible with moisture and air, tolerates a wide variety of functional groups, and is amenable to forming 11- to 13-membered heterocycles with a triple bond. The 2-propargylaniline products were treated with aluminum chloride in ethanol to afford multisubstituted indoles in moderate to excellent yields. Finally, a series of deuterium-labeling experiments was performed to elucidate the reaction mechanism.

Impact of metal-oxide nanoparticles on growth, physiology and yield of tomato (Solanum lycopersicum L.) modulated by Azotobacter salinestris strain ASM

The current study for the first time demonstrates the interference of a free-living, N-2 -fixing, and nanoparticle (NP) tolerant Azotobacter salinestris strain ASM recovered from metal-polluted soil with tomato plant-metal oxide NPs (ZnO, CuO, Al2O3 , and TiO2) interactions in a sandy clay loam soil system with bulk materials as control. Tomato plants were grown till full maturity in soils amended with 20-2000 mg kg(-1) of each metal-oxide NP with and without seed biopriming and root-inoculation of A. salinestris. A. salinestris was found metabolically active, producing considerably high amounts of bioactive indole-3-acetic-acid, morphologically unaffected, and with low alteration of cell membrane permeability under 125-1500 mu gml(-1) of NPs. However, ZnO-NPs slightly alter bacterial membrane permeability. Besides, A. salinestris secreted significantly higher amounts of extracellular polymeric substance (EPS) even under NP exposure, which could entrap the NPs and form metal-EPS complex as revealed and quantified by SEM-EDX. NPs were also found adsorbed on bacterial biomass. EPS stabilized the NPs and provided negative zeta potential to NPs. Following soil application, A. salinestris improved the plant performance and augmented the yield of tomato fruits and lycopene content even in NPs stressed soils. Interestingly, A. salinestris inoculation enhanced photosynthetic pigment formation, flower attributes, plant and fruit biomass, and reduced proline level. Bacterial inoculation also reduced the NP’s uptake and accumulation significantly in vegetative organs and fruits. The organ wise order of NP’s internalization was roots > shoots > fruits. Conclusively, A. salinestris inoculation could be an alternative to increase the production of tomato in metal-oxide NPs contaminated soils. (C) 2020 Elsevier Ltd. All rights reserved.

Modulatory Effect of Indoles on the Expression of miRNAs Regulating G1/S Cell Cycle Phase in Breast Cancer Cells

Indole-3-carbinol (I3C) is a naturally occurring glucosinolate found in Brassica vegetables that is usually converted in gastric acidic environment to the efficient metabolite 3,3 ‘-diindolylmethane (DIM). Both indoles (I3C and DIM) are known chemopreventive agents for various cancers including breast cancer. This study aimed to investigate the influence of both indoles on the tumor suppressor miRNAs (let-7a-e, miR-15a, miR-16, miR-17-5p, miR-19a, and miR-20a) and oncomiRs (miR-181a, miR-181b, miR-210, miR-221, and miR-106a), which are controlling the cell cycle key regulators: cyclin-dependent kinases (CDKs), CDK inhibitor p27(Kip1), and cyclin D1. Our results indicated that both indoles generally elevated the expression of the tumor suppressor miRNAs let-7a-e, miR-19a, miR-17-5p, and miR-20a and decreased the expression of the oncomiR list. Both indoles were able to significantly suppress the expression of CDK4 and CDK6 as well as the apoptotic markers Bcl-2 and survivin. Both indoles decreased cyclin-D1 protein, where I3C decreased cytoplasmic and nuclear cyclin-D1 significantly. Cytoplasmic and nuclear P27(Kip1)showed overexpression following treatment with I3C higher than that detected following DIM treatment. This study provides a mechanistic elucidation of the previously reported cell cycle arrest by I3C and DIM in breast cancer cells suggesting that this effect could be through modulation of miRNAs expression that, in turn, regulates the genetic network controlling the G1/S phase in cell cycle progression.
