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

open access: yesSmart 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.

Synthesis, Antioxidant and Antimicrobial Activities of a Novel Series of Chalcones, Pyrazolic Chalcones, and Allylic Chalcones

open access: yesPharmacology & Pharmacy, 2011
A new series of chalcones (4a-c) and allylicchalcones (11a-b) have been prepared by the Claisen-Schmidt condensation. A novel series of pyrazolicchalcones (5a-c) have been synthesized by the reaction of respective chalcones (4a-c) and hydrazine hydrate.

Mechanofluorochromism (MFC) of Donor–π–Acceptor (D–π–A)‐Type Fluorescent Dyes

open access: yesThe Chemical Record, EarlyView.
Mechanofluorochromism (MFC) is a photophysical phenomenon that induces changes in fluorescent colors as well as colors of organic fluorescent dyes in the solid‐state by external mechanical stimuli. In this Personal Account, we offer an insight into the mechanism for the expression of MFC and present a direction in the molecular design toward creating D–

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

open access: yesThe 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 ...

Light regulates tomato fruit metabolome via SlDML2‐mediated global DNA demethylation

open access: yesJournal of Integrative Plant Biology, EarlyView.
In tomato growth and development, red and blue light signals are captured by the photoreceptors phyB2 and CRY1a, which kickstart tomato fruit ripening by activating HY5, which activates DNA demethylation via DML2 to trigger a metabolic and ripening transformation cascade within the tomato.

Metabolo‐Transcriptomics Analyses Reveal Alfalfa Adaptation to Combined Saline‐Alkali and Low‐Temperature Stress in the Field

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Alfalfa (Medicago sativa L.) is known as the ‘King of Forage’ because of its high protein content and excellent palatability. Alfalfa productivity is adversely affected in cold regions with saline‐alkali soils. However, the mechanisms underlying the response of alfalfa to combined saline‐alkali and low‐temperature stress under field conditions
