Discovery of a novel chalcone derivative inhibiting CFTR chloride channel via AMPK activation and its anti-diarrheal application

Journal of Pharmacological Sciences, 2019
Secretory diarrhea is one of the most common causes of death world-wide especially in children under 5 years old. Isoliquiritigenin (ISLQ), a plant-derived chalcone, has previously been shown to exert anti-secretory action in vitro and in vivo by ...

A novel sulfur‐containing photoinitiator based on benzophenone derivatives for rapid photopolymerization

Smart Molecules, EarlyView.
This study develops a series of unimolecular photoinitiators, BP‐S1‐5, by incorporating hydrogen‐donating groups into a benzophenone framework. This method reduces the reliance on co‐initiators, and enables BP‐S1‐5 with efficient photoinitiation and excellent molding capability.

Enzymatic synthesis of bioactive quinolones and (thio)coumarins by fungal type III polyketide synthases

The FEBS Journal, EarlyView.
Quinolones are valuable scaffolds for drug discovery but are rare in nature. Here, we show that two fungal enzymes, AthePKS and FerePKS, can generate 2‐quinolones and two additional heteroaromatic scaffolds. Using AthePKS, we designed an artificial enzymatic cascade towards an antimicrobial quinolone from a simple precursor and implemented it in E ...
