Novel synthesis of 3,4-fused indoles

open access: yes, 2001
The goal of this project was to synthesize 3,4-fused indoles having a variety of ring sizes and a variety of functional groups. This has been accomplished by the development of a novel palladium-catalyzed route to 3,4-fused indoles. The key steps are two

The Role of the Gut Microbiota in Allogeneic Hematopoietic Cell Transplantation

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Allogeneic hematopoietic cell transplantation (allo‐HCT) is an effective treatment for patients with high‐risk hematologic malignancies. Over the last decade, gut microbiota composition during allo‐HCT has been associated with patients' outcomes.

Enantioselective Synthesis of a New Class of Stable and Functionalized Cyclopentadienes via CuH‐Catalysis

open access: yesAngewandte Chemie, EarlyView.
Cyclopentadienes (CpHs) are fundamental building blocks with widespread applications in chemistry. However, their inherent acidity and isomeric instability have long limited access to chiral variants in an asymmetric fashion. Here, we introduce a CuH‐catalyzed asymmetric transformation that provides an unprecedented entry into a new class of ...

Exosome‐mediated gut–brain axis signaling in neurodegenerative diseases: Mechanisms, experimental evidence, and therapeutic perspectives—A narrative review

open access: yesAnimal Models and Experimental Medicine, EarlyView.
The gut–brain axis is a bidirectional communication network between the intestines and brain, mediated by gut microbiota and exosomes, that regulates neuroinflammation, protein aggregation, and neuronal health processes central to neurodegenerative diseases.

Rapid Fragment Screening by 19F Steady‐State Free Precession NMR

open access: yesAngewandte Chemie, EarlyView.
19F$^{19}{\rm F}$ SSFP NMR is a broadband and very sensitive experiment for detecting protein–ligand interactions. The method enables rapid fragment screening at low micromolar protein concentrations, even for challenging drug targets such as intrinsically disordered proteins.

Single‐Atom Iron‐Catalyzed Oxidative Esterification: From Methylarenes to the Upcycling of Polystyrene and Lignin‐Derived Feedstocks

open access: yesAngewandte Chemie, EarlyView.
Heterogeneous iron‐catalyzed environmentally benign and sustainable CH‐oxidative esterification methodology has been developed for the synthesis of esters. This challenging reaction has been achieved by the rational design of specific single atom iron‐based catalyst with Fe‐N4 active centers, which empowered the oxidative esterification of methyl and ...

2‐Azaazulenium Hemicyanine Dyes for NIR‐II Multimodal Imaging and Combined Phototherapy

open access: yesAngewandte Chemie, EarlyView.
A strategically engineered class of 2‐azaazulenium hemicyanines is developed, featuring bright fluorescence in the second near‐infrared (NIR‐II) window and multifunctional performance. SWJT‐OCH3 shows type I/II reactive oxygen species (ROS) generation and excellent photothermal activity.
