Gut Microbial Catabolites of Tryptophan Are Ligands and Agonists of the Aryl Hydrocarbon Receptor: A Detailed Characterization

We examined the effects of gut microbial catabolites of tryptophan on the aryl hydrocarbon receptor (AhR). Using a reporter gene assay, we show that all studied catabolites are low-potency agonists of human AhR. The efficacy of catabolites differed substantially, comprising agonists with no or low (i3-propionate, i3-acetate, i3-lactate, i3-aldehyde), medium (i3-ethanol, i3-acrylate, skatole, tryptamine), and high (indole, i3-acetamide, i3-pyruvate) efficacies. We displayed ligand-selective antagonist activities by i3-pyruvate, i3-aldehyde, indole, skatole, and tryptamine. Ligand binding assay identified low affinity (skatole, i3-pyruvate, and i3-acetamide) and very low affinity (i3-acrylate, i3-ethanol, indole) ligands of the murine AhR. Indole, skatole, tryptamine, i3-pyruvate, i3-acrylate, and i3-acetamide induced CYP1A1 mRNA in intestinal LS180 and HT-29 cells, but not in the AhR-knockout HT-29 variant. We observed a similar CYP1A1 induction pattern in primary human hepatocytes. The most AhR-active catabolites (indole, skatole, tryptamine, i3-pyruvate, i3-acrylate, i3-acetamide) elicited nuclear translocation of the AhR, followed by a formation of AhR-ARNT heterodimer and enhanced binding of the AhR to the CYP1A1 gene promoter. Collectively, we comprehensively characterized the interactions of gut microbial tryptophan catabolites with the AhR, which may expand the current understanding of their potential roles in intestinal health and disease.

Photocatalytic Intramolecular [2+2] Cycloaddition of Indole Derivatives via Energy Transfer: A Method for Late-Stage Skeletal Transformation

Visible light-promoted dearomative [2 + 2] cycloaddition of indole derivatives tethered with olefins at the N1 position has been considered thermodynamically unfeasible due to the high triplet excited-state energies. We describe visible light-promoted [2 + 2] cycloaddition with concomitant dearomatization of indole derivatives tethered with olefins at the N1 position via the energy transfer process, providing cyclobutane-fused polycyclic indoline derivatives that are potentially useful in drug design and discovery. These cyclobutane-fused indoline-based polycycles are obtained in high yields and with good diastereoselectivities (>99:1). The key to the success of the reaction is the formation of H-bond(s) between N-alkenoylindole and solvent, enabling the reduction of the triplet energy of the indole derivatives, which greatly improved the efficiency of the protocol. The applicability of the method is demonstrated by late-stage skeletal diversification of indole-containing bioactive molecules, which provides a powerful strategy for the rapid skeleton remodeling. DFT calculations were used to give a deep understanding of the reaction pathways.

Organocatalytic Asymmetric Synthesis of Indole-Based Chiral Heterocycles: Strategies, Reactions, and Outreach

CONSPECTUS: Indole-based chiral heterocycles constitute a class of important heterocyclic compounds that are found in numerous pharmaceuticals, functional materials, and chiral catalysts or ligands. Catalytic asymmetric synthesis, for which the 2001 Nobel Prize in Chemistry was awarded, has been demonstrated to be the most efficient method for accessing chiral compounds. Therefore, the catalytic asymmetric synthesis of indole-based chiral heterocycles has attracted great interest from the scientific community. However, the strategies toward this goal are rather limited, and great challenges remain in this field, such as metal contamination in the products, the limited number of platform molecules with versatile reactivity, and the limited number of catalytic asymmetric reactions that offer high step economy, atom economy, and excellent enantiocontrol. Therefore, novel strategies for the catalytic asymmetric synthesis of indole-based chiral heterocycles are urgently needed. To achieve this goal, our group has developed a series of unique strategies, such as designing and developing versatile platform molecules and their corresponding organocatalytic asymmetric reactions to access indole-based chiral heterocycles. In this Account, we describe our efforts to address the remaining challenges in this research field. Namely, we have designed and developed vinylindoles, indolylmethanols, arylindoles and indole derivatives as versatile platform molecules for the construction of indole-based chiral heterocyclic scaffolds with structural diversity and complexity. Based on the reactivities of these platform molecules, we have designed and accomplished a series of organocatalytic asymmetric cycloaddition, cyclization, addition and dearomatization reactions with a high step economy, atom economy and excellent enantiocontrol. Using these strategies, a wide range of indole-based chiral heterocycles, including five-membered to seven-membered heterocycles, axially chiral heterocycles and tetrasubstituted heterocycles, have been synthesized with high efficiency and excellent enantioselectivity. In addition, we have investigated the properties of some indole-based chiral heterocycles, including their bioactivities and catalytic activities, and showed that these chiral heterocycles have potent anticancer activities and promising catalytic activities in asymmetric catalysis. These results help elucidate the potential applications of indole-based chiral heterocycles in drug development and chiral catalysts. The organocatalytic asymmetric synthesis of indole-based chiral heterocycles has undoubtedly become and will continue to be a hot topic in the field of asymmetric catalysis and synthesis. Our efforts, summarized in this Account, will not only open a window for the future development of innovative strategies toward organocatalytic asymmetric synthesis of indole-based chiral heterocycles but also inspire chemists worldwide to confront the remaining challenges in this field and prompt further advances.
