A highly enantioselective [4 + 2] annulation of 2-ylideneoxindole with malononitrile has been accomplished by cinchonine catalysis under mild conditions. The corresponding enantiomerically enriched 4H-pyrano[3,2-b]indoles were generated in moderate to high yields (up to 94%) with excellent enantioselectivities (up to 98% ee). To explain the stereoselectivity of the organocatalytic Michael-ammonization cascade, we also carried out the control experiments and proposed plausible transition-state models for the catalytic cycle based on the observed stereochemistry of the products. In addition, some of the products showed moderate antibacterial activity against S. aureus and S. epidermidis in vitro, which might be considered as a potential clue for the discovery of new antimicrobial agents.

Safety of 6-Chloro-5-(4-(1-hydroxycyclobutyl)phenyl)-1H-indole-3-carboxylic acid

Studies on indole-3-carboxylic acid derivatives as direct activators of human adenosine monophosphate-activated protein kinase (AMPK) alpha1beta1gamma1 isoform have culminated in the identification of PF-06409577 (1), PF-06885249 (2), and PF-06679142 (3) as potential clinical candidates. Compounds 1-3 are primarily cleared in animals and humans via glucuronidation. Herein, we describe the biosynthetic preparation, purification, and structural characterization of the glucuronide conjugates of 1-3. Spectral characterization of the purified glucuronides M1, M2, and M3 indicated that they were acyl glucuronide derivatives. In vitro pharmacological evaluation revealed that all three acyl glucuronides retained selective activation of beta1-containing AMPK isoforms. Inhibition of de novo lipogenesis with representative parent carboxylic acids and their respective acyl glucuronide conjugates in human hepatocytes demonstrated their propensity to activate cellular AMPK. Cocrystallization of the AMPK alpha1beta1gamma1 isoform with 1-3 and M1-M3 provided molecular insights into the structural basis for AMPK activation by the glucuronide conjugates.

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.

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.

“Chemical Equation Presented” The first example of central metal controlled reversal of enantioselectivity in asymmetric Friedel-Crafts alkylation of indoles andbetagamma-unsaturated alpha-ketoesters has been developed. Using the same chiral starting material derived N,N’-dioxides 1a and 1b as ligands, various indole esters 4 were obtained in good to excellent yields and enantioselectivities. The reaction also featured mild reaction conditions and remarkably low catalyst loading (down to 0.01 mol %).
