In a article, author is Zheng, Mengqi, introduce new discover of the category.

The coal pyrolysis wastewater (CPW) contributed to aquatic environment contamination with amount of aromatic pollutants, and the research on joint toxicity of the mixture of aromatic compounds was vital for environmental protection. By using Tetrahymena thermophile as non-target organism, the joint toxicity of typical nonpolar narcotics and polar narcotics in CPW was investigated. The results demonstrated that the nonpolar narcotics exerted chronic and reversible toxicity by hydrophobicity-based membrane perturbation, while polar narcotics performed acute toxicity by irreversible damage of cells. As the most hydrophobic nonpolar narcotics, indole and naphthalene caused the highest joint toxicity in 24 h with the lowest EC50mix (24.93 mg/L). For phenolic compounds, the combination of p-cresol and p-nitrophenol also showed the top toxicity (EC50mix = 10.9 mg/L) with relation to high hydrophobicity, and the joint toxicity was obviously stronger and more acute than that of nonpolar narcotics. Furthermore, by studying the joint toxicity of nonpolar narcotics and polar narcotics, the hydrophobicity-based membrane perturbation was the first step of toxicity effects, and afterwards the acute toxicity induced by electrophilic polar substituents of phenols dominated joint toxicity afterwards. This toxicity investigation was critical for understanding universal and specific effects of CPW to aquatic organisms.

A chiral SPINOL derived phosphoric acid-catalyzed asymmetric N-alkylation reaction of indoles with cyclic -diaryl-substituted N-acyl imines, which are generated in situ from 3-aryl 3-hydroxyisoindolinones, has been demonstrated. The transformation proceeds smoothly with a broad range of indoles and isoindolinone alcohols. A variety of indole derived N-alkylated tetrasubstituted chiral aminals were afforded in moderate to good yields (50-79%) with excellent enantioselectivities (up to 98% ee).

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 59-87-0, in my other articles.

The inherent ambident reactive sites (electrophilic and nucleophilic) of beta-ketodithioesters (beta-KDEs) have been realised by treating them with indoles and indole-3-carbaldehydes resulting with the formations of two different types of densely functionalized alkenes. Knoevenagel condensations of beta-KDEs with indole aldehydes have been conducted smoothly using the eco-friendly deep eutectic solvent (DES) medium to yield monoindole substituted alkenes. On the other hand, C-3 alkylation of indoles with alpha-oxoketene S,S-acetal by conjugate-addition-substitution pathway resulted in the regioselective synthesis of bisindoloyl alkenes in DES medium.

Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 3380-34-5, Name is Triclosan, molecular formula is C12H7Cl3O2, belongs to indole-building-block compound, is a common compound. In a patnet, author is Wang, Xuemei, once mentioned the new application about 3380-34-5, Product Details of 3380-34-5.

A series of indole-1-carboxylic acid aryl esters was synthesized with indole and substituted phenols as raw materials. The structures of the target compounds were validated by IR and H-1-NMR spectroscopies. The inhibitory activities of the target compounds and their potencies against marine fouling organisms were investigated. The results showed that the target compounds had significant inhibitory effects on the growth of three seaweeds: Isochrysis galbana, Platymonas subcordiformis, and Navicula, and the target compounds also had excellent inhibition on the survival of barnacle larvae. The substituent structure-activity relationships revealed a significant effect on biological inhibition activity: Compounds substituted by electron-withdrawing groups had greater bioactivities than those containing electron-donating groups. Release rate of antifoulant and marine field tests indicated the final compounds had an outstanding antifouling potency against marine fouling organisms.

Asperversiamides A-H (1-8), eight linearly fused prenylated indole alkaloids featuring an unusual pyrano[3,2-f]indole unit, were isolated from the marine-derived fungus Aspergillus versicolor. The structures and absolute configurations of these compounds were elucidated by extensive spectroscopic analyses, single-crystal X-ray diffraction, electronic circular dichroism (ECD) calculations, and optical rotation (OR) calculations. The relative configuration of C-21 of iso-notoamide B was herein revised, and a new methodology for preliminarily determining if the relative configuration of the bicyclo[2.2.2] diazaoctane moiety of a spirobicyclo[2.2.2]diazaoctane-type indole alkaloid is syn or anti was developed. The anti-inflammatory activities of the isolated compounds were all tested, and of these compounds, 7 exhibited a potent inhibitory effect against iNOS with an IC50 value of 5.39 mu M.

Arterial blood pressure (BP) is regulated by a complex network of peripheral and central (brain) mechanisms. Research suggests that gut bacteria-derived compounds may affect the circulatory system. We evaluated hemodynamic effects of indole, a gut bacteria-derived product of tryptophan, and indoxyl sulfate (indoxyl), a liver metabolite of indole. BP and heart rate (HR) were recorded in anesthetized, male, Wistar rats at baseline and after the administration of either a vehicle, indole, or indoxyl into the femoral vein (IV) or into the lateral ventricle of the brain (ICV). Besides, we evaluated the effect of pretreatment with flupentixol, a non-selective D-1, D-2, alpha(1) and 5 HT(2)A receptor blocker; pizotifen, a non-selective 5-HT1, 5-HT2A and 5HT(2c) receptor blocker; and ondansetron, a 5-HT3 blocker, on hemodynamic responses to indole and indoxyl. Vehicle infused IV and ICV did not affect hemodynamics. Indole administered IV produced a dose dependent increase in BP but not HR. In contrast, the ICV infusion of indole produced a decrease in BP and HR. Indoxyl infused IV produced an increase in BP and HR, whereas indoxyl infused ICV did not affect BP and HR. The hemodynamic effects of indole and indoxyl were inhibited by pretreatment with ondansetron and pizotifen but not flupentixol. In conclusion, indole and indoxyl sulfate affect arterial blood pressure via peripheral and central mechanisms dependent on serotonin signalling. We propose that indole and indoxyl sulfate may be mediators in the interaction between gut bacteria and the circulatory system. (C) 2017 Elsevier Ltd. All rights reserved.

The emergence and worldwide spread of drug-resistant bacteria have already posed a serious threat to human life, creating the urgent need to develop potent and novel antibacterial drug candidates with high efficacy. Indole and isatin (indole-2,3-dione) present a wide structural and mechanistic diversity, so their derivatives possess various pharmacological properties and occupy a salient place in the development of new drugs. Indole/isatin-containing hybrids, which demonstrate a promising activity against a panel of clinically important Gram-positive and Gram-negative bacteria, are privileged scaffolds for the discovery of novel antibacterial candidates. This review, covering articles published between January 2015 and May 2020, focuses on the development and structure-activity relationship (SAR) of indole/isatin-containing hybrids with potential application for fighting bacterial infections, to facilitate further rational design of novel drug candidates.
