Natural Anthraquinone‐Like Compound Extracted from Green Husk of Walnut Improves Photocatalytic H2O2 Production Catalyzed by TiO2 Nanoparticles

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a novel biomolecule/semiconductor hybrid catalyst was prepared by loading anthraquinone‐liked juglone onto anatase TiO2. This catalyst exhibited high photocatalytic activity for H2O2 production. Hydrogen peroxide (H2O2) is a vital oxidant with broad industrial applications, and its production via photocatalysis represents a highly ...

Two new phenolic glycosides from the rhizome of Gastrodia elata

, 2012
Two new phenolic glycosides, named parishins F-G (1-2), together with known parishin E, were isolated from the rhizome of Gastrodia elata. The new structures were established as 1,3-di-[4-O-(beta-D-glucopyranosyl) benzyl]-2-{4-O-[beta-D-glucopyranosyl-(1

Synthesis of S‐Linked Glycoconjugates of Monosaccharides and Levoglucosenone Derivatives Through Photoinduced Thiol–Ene Reaction Mediated by 4CzIPN and Its Water Soluble Analog

European Journal of Organic Chemistry, EarlyView.
Visible‐light thiol–ene reaction mediated by 4CzIPN enables access to hydrolytically stable S‐linked glycoconjugates from levoglucosenone‐derived thiols (Y = 91% to quant. d.r. = up to >95:5) and conventional thio‐sugars (Y = 80% to quant. d.r. = up to >95:5).

Synthesis of α‐C‐Glycoside Conjugates Promoted by 4CzIPN‐Based Porous Organic Polymers Through Giese‐Like Reaction of Glycosyl Bromides in Batch and Continuous Flow

European Journal of Organic Chemistry, EarlyView.
Visible light and a 4CzIPN‐based porous organic polymer (4CzIPN‐POP) enable Giese‐like coupling of glycosyl bromides with electron‐poor alkenes to access α‐C‐glycoside conjugates. The study shows how heterogeneous thermally activated delayed fluorescence photocatalysis can be combined with continuous flow to overcome light penetration limits and ...

Therapeutic potential of plant-derived natural products against drug-induced liver injury

Frontiers in Pharmacology
Drug-induced liver injury (DILI) is a major cause of drug development failure and post-marketing restrictions. To date, over 1,000 drugs have been reported to cause liver damage, such as acetaminophen, isoniazid, methotrexate, triptolide and so on ...

The gut microbiome and drug‐resistant epilepsy: Microbiome–antiseizure medication interactions and implications for pharmacoresistance

Epilepsia Open, EarlyView.
Abstract Drug‐resistant epilepsy (DRE) affects approximately one‐third of patients with epilepsy and represents a major unmet clinical need. While traditional hypotheses of pharmacoresistance have focused on alterations in drug targets, efflux transporter overexpression, and intrinsic disease severity, the gut microbiome has recently emerged as a ...
