Visible Light Photocatalytic Aerobic Oxygenation of Indoles and pH as a Chemoselective Switch

open access: yes, 2016
An efficient chemodivergent strategy for visible light photocatalysis is developed. In the presence of a dicyanopyrazine-derived chromophore (DPZ) photocatalyst, aerobic photooxygenation of indoles could produce either isatins or formylformanilides in ...

Auxin‐Producing Pseudomonas Recruited by Root Flavonoids Increases Rice Rhizosheath Formation through the Bacterial Histidine Kinase Under Soil Drying

open access: yesAdvanced Science, EarlyView.
Drought is a major cause of crop losses across agricultural regions. Rhizosheath formation enhances plant resistance to drought. Polyploids may tolerate stress more effectively through increased interactions with bacteria. However, the contributions of tetraploid rice associated microbiota to rhizosheath formation under soil drying remain unclear ...

Gut Metabolite Indole‐3‐Propionic Acid Regulates Macrophage Autophagy Through PPT1 Inhibiting Aging‐Related Myocardial Fibrosis

open access: yesAdvanced Science, EarlyView.
IPA is an intestinal tryptophan metabolite whose effects decline with decreased heart function. Supplementing IPA can alleviate the aging‐related myocardial fibrosis through PPT1. PPT1 is a key protein localized to lysosomes, and IPA can restore macrophage autophagy function by regulating PPT1 expresssions, thereby reducing aging‐related myocardial ...

Triarylmethyl Cation Catalysis: A Tunable Lewis Acid Organo­catalyst for the Synthesis of Bisindolylmethanes

open access: yesSynOpen, 2017
Triarylmethyl cations serve as tunable organocatalysts for the synthesis of bisindolylmethanes. The catalyst structure can be modified to increase or decrease reactivity as needed to match the requirements of the substrate. High yields are achieved for a

Breaking the Recycling Bottleneck of Thermosets via Bio‐Tailoring Technology

open access: yesAdvanced Science, EarlyView.
Recyclable thermosets are achieved by using the Bio‐Tailoring technology. The Bio‐Tailoring technology effectively addresses the longstanding paradox surrounding the recyclable and reuse properties of thermosets, breaking the recycling bottleneck of thermosets.

Anti‐Inflammatory Mechanisms of Selenium Nanosheets in Ulcerative Colitis: Protein Corona, GP130 Interaction, and Transcriptomic Profile

open access: yesAdvanced Science, EarlyView.
SeNSs provide a biocompatible, anti‐inflammatory UC therapy. SeNSs form protein coronas enriched with AKT/PI3K/NF‐κB pathway proteins, suppress GP130 via hydrophobic interactions, and inhibit pro‐inflammatory cytokines. In DSS‐induced UC mice, SeNSs reduce inflammation, tissue damage, and disease activity by modulating cytokine, chemokine, and ...

Synthesis of constrained analogues of tryptophan

open access: yesBeilstein Journal of Organic Chemistry, 2015
A Lewis acid-catalysed diastereoselective [4 + 2] cycloaddition of vinylindoles and methyl 2-acetamidoacrylate, leading to methyl 3-acetamido-1,2,3,4-tetrahydrocarbazole-3-carboxylate derivatives, is described.

Squaraine Dyes for Organic Photomultiplication Photodetectors with 220% External Quantum Efficiency at 1240 nm

open access: yesAdvanced Science, EarlyView.
The synthesis of a range of squaraine dyes is reported with maximum absorption in solution above 1100 nm. Near‐infrared sensitive organic photomultiplication photodetectors are developed. Photomultiplication occurs via squaraine hole trap‐induced injection of electrons from the external circuit.
