Nontuberculous mycobacteria (NTM) pathogens particularly infect patients with structural lung disorders. We previously reported novel indole-2-carboxamides (ICs) that are active against a wide panel of NTM pathogens. This study discloses in vivo data for two lead molecules (compounds 5 and 25) that were advanced for efficacy studies in Mycobacterium abscessus-infected mouse models. Oral administration of the lead molecules showed a statistically significant reduction in the bacterial loads in lung and spleen of M. abscessus-infected mice.

An atom-economical one-pot synthesis of a new push-pull dienaminodiones from a 3,4-dihydroxysalicylaldehyde-derived Schiff base and indoles in the presence of phenyliodine(III) diacetate is described. Variation of indoles and anilines constitute a broad substrate scope of the methodology with good to moderate yields. Formation of Schiff base followed by an indole addition to afford dienaminodione takes place in one-pot; thus, the present method serves as a sequential multicomponent reaction. The present work also serves as a methodology to afford indole variants of natural product talaroenamine B. (C) 2020 Elsevier Ltd. All rights reserved.

Indoleamine 2,3-dioxygenases (Ms) degrade L-tryptophan to kynurenines and drive the de novo synthesis of nicotinamide adenine dinucleotide. Unsurprisingly, various invertebrates, vertebrates, and even fungi produce IDO. In mammals, IDO1 also serves as a homeostatic regulator, modulating immune response to infection via local tryptophan deprivation, active catabolite production, and non-enzymatic cell signaling, Whether fungal !dos have pleiotropic functions that impact on host-fungal physiology is unclear. Here, we show that Aspergillus fumigatus possesses three ido genes that are expressed under conditions of hypoxia or tryptophan abundance. Loss of these genes results in increased fungal pathogenicity and inflammation in a mouse model of aspergillosis, driven by an alternative tryptophan degradation pathway to indole derivatives and the host aryl hydrocarbon receptor. Fungal tryptophan metabolic pathways thus cooperate with the host xenobiotic response to shape host-microbe interactions in local tissue microenvironments.

Peptic ulcer is a common disorder of the gastrointestinal system affecting people of all ages worldwide. Ethanol is one of the most common causative agents for peptic ulcer. The aim of this study was to evaluate the protective effect of two newly synthesized indole imines (389 and 393) against ethanol-induced gastric ulcer in rats. Animals were orally administered different treatments: group I-II (vehicle & ulcer controls, respectively); 0.5% aqueous CMC solution, group III (standard control; omeprazole; 20 mg/kg bw); groups IV-VI, test compound 389 (20, 40 and 60 mg/kg bw) and groups VII-IX, test compound 393 (20, 40 and 60 mg/kg bw). Various parameters including pH, gastric contents, ulcer index and percentage protection were determined and histopathological study of gastric mucosa was performed to evaluate the protective effect of the test compounds. Oral administration of the test compounds, i.e. 389 and 393 (20, 40 and 60 mg/kg bw), significantly (p < 0.05) reduced the ulcer index in a dose-dependant manner as compared to the ethanol-induced ulcer control group. The gastroprotective potential of the studied test compounds was supported by the histological examination of the gastric mucosa showing a decreased inflammatory response with less oedema and leucocyte infiltration. The study concluded that the synthesized test compounds possess antiulcerogenic potential possibly due to their anti-inflammatory effects.

A base-mediated transformation based on a designed intramolecular vinylogous Michael addition (intra-VMA) is presented to access 3-substituted 2-alkenyl indole derivatives. The reaction represents the first example of the intra-VMA for the construction of indoles. A one-pot N-allylation of ortho-tosylamidocinnamates/congeners with gamma-bromocrotonates followed by intra-VMA has been described to provide access to a diverse range of 2-alkenyl indole derivatives in reasonable to high yields. The synthetic value of the developed intra-VMA has been demonstrated by gram-scale synthesis of a representative indole derivative and also by the formal synthesis of MK-7246: a Merck’s clinical CRTH2 antagonist.

Fecal calprotectin and indole were studied in 134 subjects with recurrent CDI before and after FMT. Reduced fecal calprotectin (p = 0.0353, 95% CI 0.1305-0.1439) and rising levels of indole (p < 0.0001, 95% CI < 0.0001-0.0003) predicted successful treatment. A ratio of recal calprotectin/indole may provide prognostic value for FMT (p = 0.0004, 95% CI 0.22-0.87). (C) 2019 The Authors. Published by Elsevier Ltd.

‘On-water’ synthesis of 2,2-bis(indoly-3-yl)indoline-3-ones via N-2-selective dearomatization of ‘(N-H) protection-free’ indole derivatives is described. An oxidative homo trimerization of indole via nano Au/Pd catalysis with oxone as additive was successfully demonstrated for the first time. In situ generation of isatin at room temperature and with water as solvent are key features.

In an article, author is Sethupathy, Sivasamy, once mentioned the application of 97-59-6, Recommanded Product: Allantoin, Name is Allantoin, molecular formula is C4H6N4O3, molecular weight is 158.1154, MDL number is MFCD00005260, category is indole-building-block. Now introduce a scientific discovery about this category.

Indole and its derivatives have been shown to interfere with the quorum sensing (QS) systems of a wide range of bacterial pathogens. While indole has been previously shown to inhibit QS in Serratia marcescens, the effects of various indole derivatives on QS, biofilm formation, and virulence of S. marcescens remain unexplored. Hence, in the present study, we investigated the effects of 51 indole derivatives on S. marcescens biofilm formation, QS, and virulence factor production. The results obtained revealed that several indole derivatives (3-indoleacetonitrile, 5-fluoroindole, 6-fluoroindole, 7-fluoroindole, 7-methylindole, 7-nitroindole, 5-iodoindole, 5-fluoro-2-methylindole, 2-methylindole-3-carboxaldehyde, and 5-methylindole) dose-dependently interfered with quorum sensing (QS) and suppressed prodigiosin production, biofilm formation, swimming motility, and swarming motility. Further assays showed 6-fluoroindole and 7-methylindole suppressed fimbria-mediated yeast agglutination, extracellular polymeric substance production, and secretions of virulence factors (e.g., proteases and lipases). QS assays on Chromobacterium violaceum CV026 confirmed that indole derivatives interfered with QS. The current results demonstrate the antibiofilm and antivirulence properties of indole derivatives and their potentials in applications targeting S. marcescens virulence.
