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.

An atom-economical and environmentally benign approach for the synthesis of indole-substituted 1,4-naphthoquinones from indoles and 1,4-naphthoquinones using readily available Lewis acidic B(C6F5)(3) in water and with the recycling of water and part of the catalyst is reported.

This methodology provides a facile protocol for the synthesis of some new indole-substituted 1,4-naphthoquinones in satisfactory yields and with a broad substrate scope. When compared to known methods for the synthesis of indole-substituted 1,4-naphthoquinones, this protocol is practical and efficient and does not require a transition-metal catalyst or toxic organic solvents. In addition, we utilized a simple filtration process for complete recycling of the solvent and the part of the catalyst in each reaction cycle.

L-tryptophan (Trp) is widely used in food and feed enforcement to play an important role in biological processes. Various metabolites of Trp perform its potent function. The indole pyruvate pathway is one of the main pathways of Trp metabolism in the gut microbiota, providing numerous indole-derivatives, which can modulate intestinal homeostasis and mucosal immunity by activating the aryl hydrocarbon receptor (AHR) signaling pathway. In this study, we constructed an IL4I1-overexpressed 293T cell line and found that IL4I1 can catalyze Tip to produce indole-3-acetic acid (IAA) and indole-3-carboxaldehyde (IAld). Moreover, both IAA and IAld are accumulated in dendritic cells (DCs) and can stimulate the expression of CYP1A1. Our results demonstrate the existence of the indole pyruvate pathway in host cells with IL4I1 as the key enzyme. The IL4I1-mediated Trp metabolism implies the role of dietary impact on immunity.
