Synthesis of 2-substituted tryptophans via a C3- to C2-alkyl migration

Beilstein Journal of Organic Chemistry, 2014
The reaction of 3-substituted indoles with dehydroalanine (Dha) derivatives under Lewis acid-mediated conditions has been investigated. The formation of 2-substituted tryptophans is proposed to occur through a selective alkylative dearomatization ...

Longitudinal Modulation of the Gut Microbiome and Growth Performance by Phytochemicals as Antibiotic Alternatives in Swine Production

Animal Research and One Health, EarlyView.
We conducted a longitudinal trial across nursery, growing, and finishing phases, showing that phytochemical supplementation as a potential antibiotic alternative reduced potential pathogens and promoted beneficial Lactobacillus amylovorus in the nursery phase, and enriched amino acid and carbohydrate metabolism pathways (prediction) during finishing ...

A Metabolomic Signature Predicts Gout Flare Clinical Outcome Associated With Colchicine Prophylaxis

Arthritis &Rheumatology, EarlyView.
Objective This study investigated that serum metabolomics, before urate‐lowering therapy (ULT) initiation, could serve as a biomarker for responsiveness to colchicine prophylaxis in patients with gout commencing treat‐to‐target ULT. Methods We studied a multicenter prospective cohort (n = 409) initiating treat‐to‐target ULT plus colchicine prophylaxis.

Enhanced mitochondrial activity reshapes a gut microbiota profile that delays NASH progression

Hepatology, EarlyView., 2022
Improved mitochondrial activity, due to the lack of methylation‐controlled J protein (MCJ), creates a specific microbiota signature that when transferred through cecal microbiota transplantation delays NASH progression by restoring the gut‐liver axis and enhancing hepatic fatty acid oxidation.

Hierarchical MXene–Carbon Nanotube Architectures for High‐Stability Silicon Oxide Anodes

Batteries &Supercaps, EarlyView.
A novel MXene–CNT hierarchical framework is synthesized via molecularly driven assembly and crosslinking, enabling electrically interconnected and mechanically reinforced Si/SiOx/C composite anodes. The CNTs bridge the MXene flakes to form a robust conductive network, while the MXene surface chemistry facilitates uniform SiOx/C coating and SEI ...

Metabolic fate of drugs of abuse and new psychoactive substances: A pilot study on a novel workflow using a zebrafish embryo model combined with human microdosing

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this study was to develop a novel workflow to identify human urine biomarkers for drugs of abuse and new psychoactive substances. Metabolites of amphetamine, cocaine, LSD, MDMA, methamphetamine, THC, MDMB‐CHMICA, and MDPPP were first identified in a zebrafish embryo (ZE) metabolism study followed by comparison to most abundant human ...

Psilocybin Production With Genetically Modified Aspergillus nidulans Under Pressurized Conditions

Biotechnology and Bioengineering, EarlyView.
Shake flask cultures of psilocybin‐producing A. nidulans were investigated with respect to nitrogen source, rheology, power input, and oxygen availability, and subsequently scaled to a stirred tank reactor scale based on specific power input to develop and optimize a pressurized bioprocess.
