Cyclic bridged analogs of isoCA-4: Design, synthesis and biological evaluation

In this work, a series of cyclic bridged analogs of isocombretastatin A-4 (isoCA-4) with phenyl or pyridine linkers were designed and synthesized. The synthesis of the desired analogs was performed by the formation of nitro-vinyl intermediates, followed by a Cadogan cyclization. Structure activity relationship (SAR) study demonstrates the critical role of the combination of quinaldine as ring A, pyridine as the linker, and indole as ring B in the same molecule, for the cytotoxic activity. Among all tested compounds, compound 42 showed the highest antiproliferative activity against a panel of cancer cell lines with average IC50 values of 5.6 nM. Also, compound 42 showed high antiproliferative activity against the MDR1-overexpressing K562R cell line; thus, it was 1.5- and 12-fold more active than the reference compounds, isoCA-4 and CA-4, respectively. Moreover, 42 displayed a strong antiproliferative activity against the colon-carcinoma cells (HT-29), which are resistant to combretastatin A-4 and isoCA-4, and it was found to be 8000-fold more active than natural CA-4. Compound 42 also effectively inhibited tubulin polymerization both in vitro and in cells, and induced cell cycle arrest in G2/M phase. Next, we demonstrated that compound 42 dose-dependently caused caspase-induced apoptosis of K562 cells through mitochondrial dysfunction. Finally, we evaluated the effect of compound 42 in human no cancer cells compared to the reference compound. We demonstrated that 42 was 73 times less cytotoxic than isoCA-4 in quiescent peripheral blood lymphocytes (PBLs). In summary, these results suggest that compound 42 represents a promising tubulin inhibitor worthy of further investigation. (c) 2020 Elsevier Masson SAS. All rights reserved.

Identification and characterization of CTP:phosphocholine cytidylyltransferase CpCCT1 in the resurrection plant Craterostigma plantagineum

Phosphatidylcholine is a major phospholipid which is shown to be involved in stress adaptation. Phosphatidylcholine increased during dehydration in Craterostigma plantagineum, and therefore we characterized CTP: phosphocholine cytidylyltransferase (CpCCT1), a key regulatory enzyme for phosphatidylcholine synthesis in plants. The CpCCT1 gene from the resurrection plant C. plantagineum was cloned and the amino acid sequence was compared with homologs from other species including yeast and rat. CCT proteins have conserved catalytic and membrane-binding domains while the N-terminal and C-terminal domains have diverged. The tissue specific expression analysis indicated that CpCCT1 is expressed in all tested tissues and it is induced by dehydration and in response to 0.5 M NaCl solutions. In plants exposed to low temperature in the dark, the CpCCT1 transcript increased after 4 h at 4 degrees C. CpCCT1 expression also increased during mannitol and sorbitol treatments in a concentration dependent manner. Phytohormones such as abscisic acid and indole-3-acetic acid also trigged transcript accumulation. Comparisons of transcript and protein accumulations for different treatments (except for dehydration) suggest transcriptional and translational control mechanisms. Analysis of promoter activity and polysome occupancy suggest that CpCCT1 gene expression is mainly under translational regulation during dehydration.

Hydrogen-bonded polyamide 6/Zr-MOF mixed matrix membranes for efficient natural gas dehydration

New types of mixed matrix membranes (MMMs) were fabricated by incorporating Zr-MOF (UiO-66-NH2 and UiO66-NH3+Cl-) filler into polyamide 6 (PA 6) polymer, enabling efficient natural gas dehydration. All membranes were characterized and applied for H2O/CH4 mixtures separation at 1 bar pressure difference at 30 degrees C. It was found that the Zr-MOF nanoparticles in a size range of 0.4-0.5 mu m were successfully incorporated into the high permeability polymer PA 6 to obtain MMMs with 10-30 wt% particle loadings. MMMs loaded with 25 wt% of UiO-66-NH3+Cl- and 20 wt% of UiO-66-NH2 demonstrated ultrahigh H2O/CH4 selectivity of 747.7 and 687.4, respectively, and enhanced H2O permeability as well as H2O/CH4 selectivity compared with the pure PA 6 polymer. The excellent membrane performance attributed to direct and extensive hydrogen bonds between the polymer and MOFs. This type of MMMs could be an alternative for further research in H2O/CH4 separation at industrial scale.

A Study on the Interaction between New Indole Amide Compound and Aluminum(III) Ion

A new indole-based compound N-(pyridine-2-ylmethyl)-1H-indole-2-carboxamide (FL) which could selectively recognize Al3+ had been designed, synthesized and evaluated. FL could detect Al3+ with high sensitivity. The fluorescence intensity of FL-Al3+ solution was linear dependence to the concentration of Al3+ in the ranges from 0 to 5 mol/L. The addition of Al3+ caused quenching of fluorescence intensity and the limit of detection for Al3+ was as low as 1.79×10(-9)M. The binding ratio of FL-Al3+ was obtained 3:2 by Job’s plot and the binding constant was 9.37×10(5). Moreover, FL had been successfully applied in real sample detection.

Indolic Derivatives Metabolism in the Anaerobic Reactor Treating Animal Manure: Pathways and Regulation

The positive effect of anaerobic digestate on plant growth is attributed not only to the macronutrients it contains (e.g., nitrogen and phosphorus) but also to its high level of indole-3-acetic acid (IAA), which is one of the important plant hormones. Results of indolic derivative analysis in anaerobic reactors revealed that IAA was produced from L-tryptophan. Results of experiments using single indolic component showed that L-tryptophan metabolism under alkalescent anaerobic condition follows two pathways. (i) L-Tryptophan can be converted into skatole via IAA (ISP), and exogenous carbon can completely inhibite the process from IAA to skatole, in which IAA production is enhanced. (ii) Simultaneously, L-tryptophan can also be directly converted into indole (IPM). The mineralization of indole was enhanced by synergetic effect of L-tryptophan and other amino acids. Based on these findings, carbon source and amino acids can theoretically regulate IAA production and indole mineralization, respectively. These findings provide some new perspectives on IAA regulation and indole decontamination in liquid digestate.

Synthesis, molecular docking, and QSAR study of sulfonamide-based indoles as aromatase inhibitors

Thirty four of indoles bearing sulfonamides (11-44) were synthesized and evaluated for their antiaromatase activities. Interestingly, all indole derivatives inhibited the aromatase with IC50 range of 0.7 -15.3 mu M. Indoles (27-36) exerted higher aromatase inhibitory activity than that of ketoconazole. The phenoxy analogs 28 and 34 with methoxy group were shown to be the most potent compounds with sub-micromolar IC50 values (i.e., 0.7 and 0.8 mu M, respectively) without affecting to the normal cell line. Molecular docking demonstrated that the indoles 28, 30 and 34 could occupy the same binding site on the aromatase pocket and share several binding residues with those of the natural substrate (androstenedione), which suggested the competitive binding could be the mode of inhibition of the compounds. The most potent analog 28 could mimic H-bondinteractions of the natural androstenedione with MET374 and ASP309 residues on the aromatase. QSAR model also revealed that the para-phenoxy indole (28) affords the higher value of electronegativity descriptor MATS6e as well as the higher inhibitory activity compared with that of the ortho-phenoxy compound (34). The study highlighted a series of promising indoles to be potentially developed as novel aromatase inhibitors for therapeutics. (C) 2017 Elsevier Masson SAS. All rights reserved.

Pseudo-five-component synthesis of indolone-3-aminopropenylidene merocyanine dimers and their attenuated aggregation-induced emission

Four indolone-3-aminopropenylidene merocyanine dimers and a reference alpha-indolonyl-gamma-amino merocyanine are readily synthesized in a consecutive multicomponent insertion-alkynylation-addition sequence in a one-pot fashion. The rotational barriers of the terminal amino moieties were estimated by variable temperature NMR measurements and the observed coalescence at room temperature to lie in the same margin as for beta-pyrrolidinyl enoates. While the mono merocyanine, chosen as a reference, displays the expected 1300 fold increase in emission intensity upon induced aggregation, the merocyanine dimers, although intense in their absorption behavior and redshifted in their emission maxima, only show a 50-60 fold fluorescence increase. The considerable attenuation of emission of the merocyanine dimers in the amorphous solid state supports the finding that unimolecular symmetrical merocyanine dimers of this type are not intensive AIE systems.

Indole: The After Next Scaffold of Antiplasmodial Agents?

Malaria remains a global public health problem due to the uphill fight against the causative Plasmodium parasites that are relentless in developing resistance. Indole-based antiplasmodial compounds are endowed with multiple modes of action, of which inhibition of hemozoin formation is the major mechanism of action reported for compounds such as cryptolepine, flinderoles, and isosungucine. Indole-based compounds exert their potent activity against chloroquine-resistant Plasmodium strains by inhibiting hemozoin formation in a mode of action different from that of chloroquine or through a novel mechanism of action. For example, dysregulating the sodium and osmotic homeostasis of Plasmodium through inhibition of PfATP4 is the novel mechanism of cipargamin. The potential of developing multi-targeted compounds through molecular hybridization ensures the existence of indole-based compounds in the antimalarial pipeline.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 546-43-0, in my other articles.

Orientation-dependent effects of indeno [1,2-b] indole-spirofluorene donor on photovoltaic performance of D-pi-A and D-D-pi-A sensitizers

Dyes JY70-73 based on indeno[1,2-b]indole-spirofluorene (IISF) donor have been synthesized and applied in dye-sensitized solar cells, two of them feature donor-pi-acceptor (D-pi-A) configuration and the others adopt a D-D-pi-A structure. Orientation-dependent effects of IISF donor are clearly observed in the photovoltaic properties of D-pi-A type dyes JY70 and JY72, though close power conversion efficiency (PCE) achieves finally owing to the trade-off effect of open-circuit voltage (V-OC) and short-circuit current density (J(SC)). By contrast, regioisomeric dyes JY71 and JY73 with an auxiliary diphenylamine donor present a significantly different photovoltaic performance. Under the [Co(phen)(3)](2+/3+) electrolyte, device based on JY73 gives much higher V-OC and J(SC), hence a greater PCE (7.40%) which is over two times higher than its regioisomeric JY71 (3.31%). Reasons for that have been systematically investigated. Cocktail co-sensitizations of dyes JY73 and JY70/JY72 both promote the PCEs up to over 8%, and device based on JY72&JY73 achieves the highest PCE of 8.32%.
