Aggregation-induced emission with white, green, or blue luminescence from biologically-active indole derivatives

Among several advantages of single-chromophore white-light-emitting dyes over mixed dyes are their phase stability and fabrication low-cost. Also, materials with aggregation-induced emission (AIE) have been employed as good bioprobes for DNA and for detecting some biomacromolecules sensitively and selectively. To be suitable for biological applications, the molecule should have AIE properties and be biocompatible. Indoles are electron-rich unsaturated compounds that display photophysical properties with potential applications such as fluorescent probes in addition to their widespread biological activities. Materials characterized with white-color emission, AIE activity, and biocompatibility are presented in this work. The thermal behavior and photophysical properties of some indole derivatives have been studied experimentally and theoretically using density functional theory. Besides their reported biological activities, the studied indole dyes show high thermal stabilities and ME behavior. Some dyes gave white-color luminescence from a single chromophore, while others produced blue or green emissions. Theoretical and experimental results indicate that the different emission behavior of these dyes resulted from forming various kinds of aggregates with different intermolecular interactions.

Cu(II)-Catalyzed Oxidative Trifluoromethylation of Indoles with KF as the Base

This paper offers an efficient copper-catalyzed oxidative trifluoromethylation of indoles with low-cost CF3SO2Na via C-H activation. Notably, the use of a base is crucial for the trifluoromethylation of indoles. This reaction proceeds efficiently in good to excellent yields and is tolerance of a broad range of functional groups. Furthermore, melatonin, a medicine for sleep disorders, is converted to its 2-CF3 analogue in 68% yield. Studies of possible reaction pathways suggest that this reaction proceeds through a radical process.

C7-Indole Amidations and Alkenylations by Ruthenium(II) Catalysis

C7-H-functionalized indoles are ubiquitous structural units of biological and pharmaceutical compounds for numerous antiviral agents against SARS-CoV or HIV-1. Thus, achieving site-selective functionalizations of the C7-H position of indoles, while discriminating among other bonds, is in high demand. Herein, we disclose site-selective C7-H activations of indoles by ruthenium(II) biscarboxylate catalysis under mild conditions. Base-assisted internal electrophilic-type substitution C-H ruthenation by weak O-coordination enabled the C7-H functionalization of indoles and offered a broad scope, including C-N and C-C bond formation. The versatile ruthenium-catalyzed C7-H activations were characterized by gram-scale syntheses and the traceless removal of the directing group, thus providing easy access to pharmaceutically relevant scaffolds. Detailed mechanistic studies through spectroscopic and spectrometric analyses shed light on the unique nature of the robust ruthenium catalysis for the functionalization of the C7-H position of indoles.

Metal and Oxidant Free Construction of Substituted- and/or Polycyclic Indoles: A Useful Alternative to Bischler and Related Syntheses

A wide range of substituted indoles or polycyclic derivatives containing the indole core are easily accessible by acidic treatment of aromatic amines and 1,2-diaza-1,3-dienes. Unlike the related indole-Bischler synthesis, the regioselectivity of the method here reported is unique and predictable, the yields are generally good and also electron withdrawing substituted indoles are smoothly recovered.

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.

Mechanistic Perspectives in the Regioselective Indole Addition to Unsymmetrical Silyloxyallyl Cations

Our investigations on the reaction mechanism to account for regioselectivity on the addition of indoles to unsymmetrical silyloxyallyl cations are reported. Using both experimental and computational methods, we confirmed the significance of steric effects from the silyl ether group toward directing the inward approach of indoles, leading to nucleophilic attack at the less substituted electrophilic alpha’-carbon. The role of residual water toward accelerating the rate of reaction is established through stabilization of the participating silyloxyallyl cation.

Selective Syntheses of Benzo[b]carbazoles and C3-Substituted Indoles via Tunable Catalytic Annulations of beta-Alkynyl Ketones with Indoles

Tunable catalytic annulation reactions of beta alkynyl ketones with indoles have been developed, enabling multiple chemical bond-forming events to selectively access skeletally diverse indole-containing heterocycles with generally good yields. Silver-catalyzed intermolecular benzannulation reaction of beta-alkynyl ketones with indoles afforded tetracyclic benzo[b]carbazoles whereas isochromen-1-yl-substituted indoles could be obtained using the same silver catalysis by lowering the reaction temperature (0 degrees C or rt). Interestingly, using Sc(OTf)(3)and AgOTf as a combined catalytic system led to the formation of C3-naphthylated indolesviaintramolecular benzannulation reaction.

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. you can also check out more blogs about 348640-06-2. Quality Control of 4-Bromo-7-azaindole.

Synergistic Dual Role of [hmim]Br-ArSO2Cl in Cascade Sulfenylation-Halogenation of Indole: Mechanistic Insight into Regioselective C-S and C-S/C-X (X = Cl and Br) Bond Formation in One Pot

Bifunctionalized indoles are an important class of biologically active heterocyclic compounds and potential drug candidates. Because of the lack of efficient synthetic methods, one pot cascade synthesis of these compounds is rare and remains a challenge. To expand this field, we herein disclose a step-economical and temperature tunable strategy wherein the synergistic effect between [hmim]Br-ArSO2Cl leads exclusively to the formation of 3-arylthio indole via sulfenylation of indole at room temperature, while heating the reaction mixture at 50 degrees C provided an unexpected 2-halo-3-arylthio indole with construction of C-S and C-S/C-X (X = Cl and Br) bonds without addition of any external halogenating agent via cascade sulfenylation-halogenation reactions under metal-oxidant-base-free conditions. Further, insight into the reaction mechanism provides an unprecedented observation wherein the synergistic interaction between [hmim]Br-ArSO2X in the presence of a catalytic amount of water generates arylsulfonic anhydride (ArSO2)(2)O in situ as a new sulfur source along with the formation of [hmim]PTS as probed by NMR, ESI-MS, DART-MS, and HPLC studies. Notably, the mixture of bifunctionalized 2-halo(Br/Cl)-3-arylthio indole was smoothly diversified with privileged heterocycle triazole to provide 2-(1H-triazole-1-yl)-3-arylthio indole, which is an analogue of the potent indole-based anticancer agent.

Regiodivergent Trifluoromethanesulfonic Acid-Promoted Cycloisomerizations of Ynenamines to Fused Indoles

Trifluoromethanesulfonic acid (TfOH)-mediated cycloisomerizations were controlled through the choice of the electron-withdrawing functional group at C3 of indoles to provide pyrrolo[3,2,1-ij]quinolines and benzo[3,4]azepino[1,2-a]indoles via 6-endo-dig and 7-endo-dig cyclizations, respectively. The natures of the different cyclizations could be controlled by tuning the electronic influences; indole substrates with carbonyl groups (such as -CO2Et and -COMe) gave products with six-membered rings, while substrates with sulfonyl groups (such as -Ts and -Ms) gave products with seven-membered rings in moderate to good yields. By comparison, electronically-neutral substituents (such as -Ph and -H) turned out to give seven-membered products through different mechanism.
