Chemical Equation Presentation An unusual rhodium carbenoid approach for introduction of 4-substltuted (Z)-pent-2-enoates into sterically encumbered pyrroles and indoles is described. These studies show that (Z)-vinylcarbenoids have a greater tendency than (E)-vinylcarbenoids to react at the vinylogous position of the carbenoid rather than at the carbenoid center

Bromination is a fundamental transformation in organic chemistry and brominated compounds as building blocks are of paramount importance in organic synthesis. In our study, we have developed an efficient method of bromination by using a CFBSA/KBr system at room temperature in a short reaction time. Notably, this approach has been proven to be applicable to a range of substrates including 1,3-diketones and beta-keto esters, phenols, aromatic amines and heteroarenes with good to excellent yields.

Derivatives of the amino acid tryptophan (Trp) serve as precursors for the chemical and biological synthesis of complex molecules with a wide range of biological properties. Trp analogues are also valuable as building blocks for medicinal chemistry and as tools for chemical biology. While the enantioselective synthesis of Trp analogues is often lengthy and requires the use of protecting groups, enzymes have the potential to synthesize such products in fewer steps and with the pristine chemo- and stereoselectivity that is a hallmark of biocatalysis. The enzyme TrpB is especially attractive because it can form Trp analogues directly from serine (Ser) and the corresponding indole analogue. However, many potentially useful substrates, including bulky or electron-deficient indoles, are poorly accepted. We have applied directed evolution to TrpB from Pyrococcus furiosus and Thermotoga maritima to generate a suite of catalysts for the synthesis of previously intractable Trp analogues. For the most challenging substrates, such as nitroindoles, the key to improving activity lay in the mutation of a universally conserved and mechanistically important residue, E104. The new catalysts express at high levels (>200 mg/L of Escherichia coli culture) and can be purified by heat treatment; they can operate up to 75 C (where solubility is enhanced) and can synthesize enantiopure Trp analogues substituted at the 4-, 5-, 6-, and 7-positions, using Ser and readily available indole analogues as starting materials. Spectroscopic analysis shows that many of the activating mutations suppress the decomposition of the active electrophilic intermediate, an amino-acrylate, which AIDS in unlocking the synthetic potential of TrpB.

Herein, we have developed a novel approach for synthesizing symmetrical and unsymmetrical 3,3-bis(indolyl)methane derivatives via CuI-catalyzed C[sbnd]H functionalization of indole using indole-3-tosylhydrazones as carbene precursor. This procedure works well with different substitutions such as NO2, Br, CH3 and OMe on indole or indole-3-tosylhydrazones and features high regioselectivity for C-3 functionalization over the C-1 and N-1 positions. Further, we have also revealed the feasibility of this protocol in a one-pot fashion starting from indole-3-carboxyaldehyde.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: 5-Nitro-1H-indole-3-carbaldehyde, you can also check out more blogs about6625-96-3

The indolealkylamine 5-hydroxytryptamine (5-HT, 0.1 nM-1 muM) caused dose-dependent increases in the number of contractions observed in guts isolated from the caterpillar Spodoptera frugiperda. Of the 5-HT analogues tested for agonist action, 2-methyl-5-HT (0.1-10 muM) was a full agonist with reduced potency while alpha-methyl-5-HT (0.1-100 muM), 5-carboxamidotryptamine (0.1-100 muM), 5-methoxytryptamine (5-MeOT) (10 nM-10 muM), and tryptamine (1-100 muM) were partial agonists. Incubation of isolated guts with proven mammalian 5-HT receptor antagonists showed that cyproheptadine (10 nM-1 muM), MDL 72222 (1-10 muM), tropisetron (1-10 muM) and 5-benzoyloxygramine (1-10 muM) were potent non-competitive antagonists of 5-HT-induced tissue contraction. In comparison, ketanserin (0.1-1 muM) was a competitive antagonist. The mammalian selective serotonin reuptake inhibitors, clomipramine (10 nM-10 muM) and fluoxetine (10 nM-10 muM) also caused non-competitive inhibition of 5-HT-induced contraction while fluvoxamine (10 nM-10 muM) was a weak competitive antagonist. Low doses of clomipramine (0.1 muM) caused potentiation of 5-HT-induced gut contraction thereby suggesting the presence of 5-HT reuptake systems in this tissue. The contractile effects of 5-HT were inhibited by verapamil, Li+ and H7 and potentiated by theophylline thereby indicating that L-type Ca2+ channels, phosphatidylinositol second messengers and cAMP, respectively, are involved in 5-HT-induced tissue contraction. The 5-HT receptors mediating contractility in the gut of S. frugiperda have properties in common with mammalian 5-HT2 and Drosophila 5- HTdro2A/2B receptors. In addition, these data suggest that the tissue also contains receptors that are similar to mammalian 5-ht6 and 5-HT7 as well as Drosophiladro1 receptors. However, the primary amino acid sequence of these lepidopteran 5-HT receptors will have to be elucidated before full comparisons can be made.

Background/objectives: Low-grade chronic inflammation in visceral adipose tissue and the intestines are important drivers of obesity associated insulin resistance. Bioactive compounds derived from plants are an important source of potential novel therapies for the treatment of chronic diseases. In search for new immune based treatments of obesity associated insulin resistance, we screened for tissue relevant anti-inflammatory properties in 20 plant-based extracts. Methods: We screened 20 plant-based extracts to assess for preferential production of IL-10 compared to TNFalpha, specifically targetting metabolic tissues, including the visceral adipose tissue. We assessed the therapeutic potential of the strongest anti-inflammatory compound, indigo, in the C57BL/6J diet-induced obesity mouse model with supplementation for up to 16 weeks by measuring changes in body weight, glucose and insulin tolerance, and gut barrier function. We also utilized flow cytometry, quantitative PCR, enzyme-linked immunosorbent assay (ELISA), and histology to measure changes to immune cells populations and cytokine profiles in the intestine, visceral adipose tissue (VAT), and liver. 16SrRNA sequencing was performed to examine gut microbial differences induced by indigo supplementation. Results: We identifed indigo, an aryl hydrocarbon receptor (AhR) ligand agonist, as a potent inducer of IL-10 and IL-22, which protects against high-fat diet (HFD)-induced insulin resistance and fatty liver disease in the diet-induced obesity model. Therapeutic actions were mechanistically linked to decreased inflammatory immune cell tone in the intestine, VAT and liver. Specifically, indigo increased Lactobacillus bacteria and elicited IL-22 production in the gut, which improved intestinal barrier permeability and reduced endotoxemia. These changes were associated with increased IL-10 production by immune cells residing in liver and VAT. Conclusions: Indigo is a naturally occurring AhR ligand with anti-inflammatory properties that effectively protects against HFD-induced glucose dysregulation. Compounds derived from indigo or those with similar properties could represent novel therapies for diseases associated with obesity-related metabolic tissue inflammation.

A prolonged increase in pro-inflammatory cytokines, TNF-alpha and IL-6 occurs in inflammatory diseases. Although existing therapies like steroids and TNF-alpha antagonists are effective they may cause serious adverse effects. We describe the preparation and evaluation for anti-inflammatory activity of 11 novel derivatives of indoline carbamates with a propionic ester, 2-aminoethyl, 3-aminopropyl 2-(dimethylamino)ethyl or 3-(dimethylamino)propyl group in positions 3 or 1. Compounds 25, 26 and 29 were previously shown to inhibit acetylcholinesterase with IC50s ranging from 0.4 to 55 muM and to prevent cytotoxicity induced by reactive oxygen species in a concentration range of 100 pM-1 muM. Compounds 25, 26, 29, 9, 10, 17 and 18, reduced NO, TNF-alpha and IL-6 at concentrations of 1-10 pM in LPS-activated RAW-264.7 and mouse peritoneal macrophages. The reduction in cytokines by compound 25 was associated with an increase in IkappaBalpha degradation and a decrease in the phosphorylation of p38 but not that of ERK. Conclusion: Indoline derivatives substituted at position 3 with chains carrying ester or amino groups may have potential for the treatment of chronic inflammatory and neurodegenerative diseases.
