An Unexpected FeCl3-Catalyzed Cascade Reaction of Indoles and o-Hydroxychalcones for the Assembly of Chromane-Bridged Polycyclic Indoles

An unexpected FeCl3-catalyzed cascade reaction of simple indoles and o-hydroxychalcone was reported, leading to densely functionalized and strained chromane-bridged polycyclic indoles in moderate to good yields. This reaction not only establishes a new transformation of indoles and o-hydroxychalcones but also provides an efficient method for the synthesis of structurally complex and congested chromane-bridged polycyclic indoles.

Design, synthesis and structure activity relationships of indazole and indole derivatives as potent glucagon receptor antagonists

A novel series of indazole/indole derivatives were discovered as glucagon receptor (GCGR) antagonists through scaffold hopping based on two literature leads: MK-0893 and LY-2409021. Further structure-activity relationship (SAR) exploration and optimization led to the discovery of multiple potent GCGR antagonists with excellent pharmacokinetic properties in mice and rats, including low systemic clearance, long elimination half-life, and good oral bioavailability. These potent GCGR antagonists could be used for potential treatment of type II diabetes.

Dietary Indole-3-Carbinol Activates AhR in the Gut, Alters Th17-Microbe Interactions, and Exacerbates Insulitis in NOD Mice

The diet represents one environmental risk factor controlling the progression of type 1 diabetes (T1D) in genetically susceptible individuals. Consequently, understanding which specific nutritional components promote or prevent the development of disease could be used to make dietary recommendations in prediabetic individuals. In the current study, we hypothesized that the immunoregulatory phytochemcial, indole-3-carbinol (I3C) which is found in cruciferous vegetables, will regulate the progression of T1D in nonobese diabetic (NOD) mice. During digestion, I3C is metabolized into ligands for the aryl hydrocarbon receptor (AhR), a transcription factor that when systemically activated prevents T1D. In NOD mice, an I3C-supplemented diet led to strong AhR activation in the small intestine but minimal systemic AhR activity. In the absence of this systemic response, the dietary intervention led to exacerbated insulitis. Consistent with the compartmentalization of AhR activation, dietary I3C did not alter T helper cell differentiation in the spleen or pancreatic draining lymph nodes. Instead, dietary I3C increased the percentage of CD4(+)ROR gamma t(+)Foxp3(-) (Th17 cells) in the lamina propria, intraepithelial layer, and Peyer’s patches of the small intestine. The immune modulation in the gut was accompanied by alterations to the intestinal microbiome, with changes in bacterial communities observed within one week of I3C supplementation. A transkingdom network was generated to predict host-microbe interactions that were influenced by dietary I3C. Within the phylum Firmicutes, several genera (Intestinimonas, Ruminiclostridium 9, and unclassified Lachnospiraceae) were negatively regulated by I3C. Using AhR knockout mice, we validated that Intestinimonas is negatively regulated by AhR. I3C-mediated microbial dysbiosis was linked to increases in CD25(high) Th17 cells. Collectively, these data demonstrate that site of AhR activation and subsequent interactions with the host microbiome are important considerations in developing AhR-targeted interventions for T1D.

Indole-N-Carboxylic Acids and Indole-N-Carboxamides in Organic Synthesis

Indoles are ubiquitous structures that are found in natural products and biologically active molecules. The synthesis of indoles and indole-involved synthetic methodologies in organic chemistry have been receiving considerable attention. Indole-N-carboxylic acids and derived indole-N-carboxamides are intriguing compounds, which have been widely used in organic synthesis, especially in multicomponent reactions and C-H functionalization of indoles. This Minireview summarizes the advances of reactions involving indole-N-carboxylic acids and indole-N-carboxamides in organic chemistry, and discusses the synthetic potential and perspective of this field.

Stereoselective preparation of methylenecyclobutane-fused angular tetracyclic spiroindolines via photosensitized intramolecular [2+2] cycloaddition with allene

Irradiation of 3-(hexa-4,5-dienyl)indole derivatives in the presence of 3′,4′-dimethoxyacetophenone by a high-pressure mercury lamp through Pyrex glass gave the corresponding [2+2] cycloaddition products stereoselectively in high yields. The major product was a methylenecyclobutane-fused angular tetracyclic spiroindoline derivative produced by the [2+2] cycloaddition through a parallel orientation. The minor product was a hexahydromethanocarbazole derivative through a crossed orientation. Electron-withdrawing substituents, such as acyl or alkoxycarbonyl, on the indole nitrogen were suitable for this reaction. (C) 2019 Elsevier Ltd. All rights reserved.

A survey of core replacements in indole-based HIV-1 attachment inhibitors

Indole- and azaindole-based glyoxylyl amide derivatives have been described as HIV-1 attachment inhibitors (AIs) that act by blocking the interaction between the viral gp120 coat protein and the human host cell CD4 receptor. As part of an effort to more deeply understand the role of the indole/azaindole heterocycle in the expression of antiviral activity, a survey of potential replacements was conducted using parallel synthesis methodology. The design and optimization was guided by a simple 2-dimensional overlay based on an overall planar topography between the indole/azaindole and C-7 substituents that had been deduced from structure-activity studies leading to the discovery of temsavir (3). 2-Substituted naphthalene- and quinoline-derived chemotypes emerged as the most interesting prototypes, with C-5 and C-6 substituents enhancing antiviral potency. Despite the fact that neither of these chemotypes incorporated a H-bond donor that has been shown to engage the side chain carboxylate of Asp(113) in gp120, the antiviral potency of several analogues met or exceeded that of 3, demonstrating that engaging Asp(113) is not a prerequisite for potent antiviral activity.

Myoglobin-Catalyzed C-H Functionalization of Unprotected Indoles

Functionalized indoles are recurrent motifs in bioactive natural products and pharmaceuticals. While transition metal-catalyzed carbene transfer has provided an attractive route to afford C3-functionalized indoles, these protocols are viable only in the presence of N-protected indoles, owing to competition from the more facile N-H insertion reaction. Herein, a biocatalytic strategy for enabling the direct C-H functionalization of unprotected indoles is reported. Engineered variants of myoglobin provide efficient biocatalysts for this reaction, which has no precedents in the biological world, enabling the transformation of a broad range of indoles in the presence of ethyl -diazoacetate to give the corresponding C3-functionalized derivatives in high conversion yields and excellent chemoselectivity. This strategy could be exploited to develop a concise chemoenzymatic route to afford the nonsteroidal anti-inflammatory drug indomethacin.
