Reported herein is the rhodium(III)-catalyzed C-H activation of anilines bearing an N-isoquinolyl directing group for oxidative [3+2] annulation with four classes of internal alkynes, leading to atroposelective indole synthesis via dynamic kinetic annulation with C-N reductive elimination constituting the stereo-determining step. This reaction proceeds under mild conditions with high regio- and enantioselectivity and functional group compatibility.

Optimization of the side-chain of a phenyl indole scaffold identified from a high-throughput screening campaign for inhibitors of the AAA+ ATPase p97 is reported. The addition of an N-alkyl piperazine led to high potency of this series in a biochemical assay, activity in cell-based assays, and excellent pharmaceutical properties. Molecular modeling based on a subsequently obtained cryo-EM structure of p97 in complex with a phenyl indole was used to rationalize the potency of these allosteric inhibitors.

Heteroaromatic indoles play a leading role in the development of pharmaceutical, medical, chemical and agricultural fields due to their structural properties. In this study, it was first time that biological properties of (antioxidant, antimicrobial, cytotoxic and apoptotis-induced anticancer) 3-(5-bromothiophen-2-yl)-1-ethyl-2-phenyl-1H-indole 4 and 3-([2,2 ‘-bithiophen]-5-yl)-1-ethyl-2-phenyl-1H-indole 5 were described. According to the overall results, while 4 did not show any significant cytotoxic, antioxidant and antimicrobial activities, 5 showed high reducing activity and very strong antibacterial activity against Enterococcus faecalis. Furthermore, 5 showed dose-dependent cytotoxic effect in all tested cell lines. The EC50 values of the 5 were found to be 16 mu M for CaCo-2, 29 mu M for LnCaP, 14 mu M for MDA-MB231, 21 mu M for HepG2 and 87 mu M for HEK293 cells, respectively. 5 also caused induction of apoptosis and promising glutathione S-transferase (GST) enzyme inhibition in HepG2 cells. Consequently, 5 could be also considered as a promising medical agent in cancer treatment.

Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Huc, Tomasz, once mentioned the application of 138786-67-1, Name is Pantoprazole sodium, molecular formula is C16H14F2N3NaO4S, molecular weight is 405.35, MDL number is MFCD01658543, category is indole-building-block.

Portal hypertension (PH) is a potentially life-threatening condition. We investigated the effects of indole and dietary tryptophan. a substrate for gut bacterial production of indole, on portal blood pressure (PBP), portal blood flow (PBF), and arterial blood pressure (ABP) in Sprague-Dawley rats (SD) and SD with PH induced by liver cirrhosis (SD-PH). Hemodynamics were recorded in anesthetized male 28-wk-old SD and SD-PH at baseline and after the administration of either a vehicle or indole into the colon. Blood levels of tryptophan and its bacterial metabolites were evaluated using chromatography coupled with mass spectrometry. Indole at lower doses increased PBP and PBF. Indole at higher doses produced a transient increase in PBP, which was accompanied by a decrease in ABP. Portal blood levels of indole, indole-3-propionic, indole-3-lactic. and indole-3-acetic acids were higher in SD-PH, suggesting an increased gut-blood barrier permeability. Rats on a tryptophan-rich diet showed a significantly higher PBP and portal blood level of indoles than rats on a tryptophan-free diet. In conclusion, a tryptophan-rich diet and intracolonic indole increase PBP and portal blood level of indole. Rats with PI I show an increased penetration of indoles from the colon to the circulation. Intracolonic indole production may be of therapeutic importance in PH.

Separation and purification of indole present in model coal tar fraction was examined by the combination of extraction to separate indole from the crude model coal tar fraction, distillation to obtain high concentration of indole in the extract, and solute crystallization (SC) to obtain high-purity indole present in indole-enriched distillate. The model fraction was made up of four types of nitrogen heterocyclic compounds (quinoline, iso-quinoline, 4.66% indole, and quinaldine), three types of bicyclic aromatic compounds (1-methylnaphthalene, 2-methylnaphthalene, and dimethylnaphthalene), biphenyl, and phenyl ether. Aqueous solutions of formamide and n-hexane were used as the extraction solvent and the SC solvent, respectively. Through the combination of formamide extraction, distillation, and SC using n-hexane in this work, 99.5% indole was recovered. We confirmed that the combination examined by this work was one of the very useful combinations for the high-purity purification of indole present in the coal tar fraction.

In a document, author is Borpatra, Paran J., Safety of SIS3.

Here, we have developed a 3-component one-pot sequential approach to 3-substituted indoles. The main advantages of this process are step economy, reduced waste, and operational simplicity. The method involves in situ generation of 3-indolylalcohols from the reaction of indoles and aldehydes in the presence of base. Further, nucleophilic substitution of 3-indolylalcohols with various nucleophiles affords 3-substituted indole derivatives. The reaction does not requires any hazardous and expensive metal catalyst. In addition, the reaction is carried out in (1:1) ethanol-water which is considered as environmentally benign solvent. On the other hand, nonsequential 3-component reaction results in the formation of unwanted bisindolylmethanes. [GRAPHICS] .

The Summary of main observation and conclusion A new class of indole-based allylic donors have been designed and developed for palladium-catalyzed decarboxylative allylations. In addition, the first application of these indole-based allylic donors in palladium-catalyzed decarboxylative [3+2] cycloaddition and allylic amination has been achieved by reacting with isocyanates and sulfonyl amines, respectively. This approach represents the first design of indole-based allylic donors, which is helpful for settling the challenge of designing and developing new class of heterocycle-based allylic donors for Pd-catalyzed decarboxylative allylation reactions.

Indole-3-acetic acid biosynthesis and its regulation in plant-associated bacteria

Numerous studies have reported the stimulation of plant growth following inoculation with an IAA-producing PGPB. However, the specific mode of IAA production by the PGPB is rarely elucidated. In part, this is due to the overwhelming complexity of IAA biosynthesis and regulation. The promiscuity of the enzymes implicated in IAA biosynthesis adds another element of complexity when attempting to decipher their role in IAA biosynthesis. To date, the majority of research on IAA biosynthesis describes three separate pathways classified in terms of their intermediates-indole acetonitrile (IAN), indole acetamide (IAM), and indole pyruvic acid (IPA). Each of these pathways is mediated by a set of enzymes, many of which are traditionally assumed to exist for that specific catalytic role. This lends the possibility of missing other, novel, enzymes that may also incidentally serve that function. Some of these pathways are constitutively expressed, while others are inducible. Some enzymes involved in IAA biosynthesis are known to be regulated by IAA or by IAA precursors, as well as by a multitude of environmental cues. This review aims to provide an update to our current understanding of the biosynthesis and regulation of IAA in bacteria.

Methylene Surrogates for the Synthesis of 3,3′-Diindolylmethanes

Di(1H-indol-3-yl)methanes (DIMs) and their derivatives are one of the highly essential indole derivatives with a broad spectrum of biological activities. The scaffold involves two indole/substituted indole moieties connected to each otherviaa methenyl bridge generally at the 3,3′ positions, as well as 2,2′ and 2,3′ positions. Synthesis of such moieties with the use of easily available chemicals and process is highly desirable for its tremendous importance in the fields of organic and medicinal chemistry. Herein, we review the synthesis of 3,3′-methylene bridged indoles with the use of some methylene surrogates under various chemical and catalytic conditions.
