Direct synthesis, characterization, in vitro and in silico studies of simple chalcones as potential antimicrobial and antileishmanial agents

Royal Society Open Science
Chalcone represents a vital biosynthetic scaffold owing to its numerous therapeutic effects. The present study was intended to synthesize 17 chalcone derivatives (3a–q) by direct coupling of substituted acetophenones and benzaldehyde.

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.

Gaining insights into epigenetic memories through artificial intelligence and omics science in plants

Journal of Integrative Plant Biology, EarlyView.
This review explores how artificial intelligence and machine learning predict plant behavior in response to environmental stress by modeling molecular regulatory networks of plant stress responses. Their combined application with omics methods opens new avenues in understanding the functioning of plant memory and future plant memory‐based plant ...

Change Your Diet: How CO2, Plant Phenology and Genotype Alter Grapevine Quality and Affect Performance and Larval Transcriptome of an Insect Herbivore

Molecular Ecology, EarlyView.
ABSTRACT Herbivorous insects need to cope with changing host plant biochemistry caused by abiotic and biotic impacts, to meet their dietary requirements. Larvae of the multivoltine European grapevine moth Lobesia botrana, one of the main insect pests in viticulture, feed on both flowers and berries.

In vitro and in vivo anticancer studies of 2'-hydroxy chalcone derivatives exhibit apoptosis in colon cancer cells by HDAC inhibition and cell cycle arrest [PDF]

Considering the therapeutic values of bioflavonoids in colon cancer treatment, six 2′-hydroxy chalcones (C1-C6) were synthesized, characterized and screened for in vitro cytotoxicity on human colon carcinoma (HCT116) and African green monkey kidney ...

A Review of the Mechanisms of Action of the Herbal Medicine, STW 5‐II, Underlying Its Efficacy in Disorders of Gut–Brain Interaction

Neurogastroenterology &Motility, EarlyView.
The pathophysiology of functional dyspepsia and irritable bowel syndrome includes altered motility, secretion, sensitivity to sensory signals, impaired epithelial barrier function, inflammation, and gut dysbiosis. The phytomedicine, STW 5‐II, represents a multi‐targeted approach, addressing these pathophysiologies.

Phytochrome A is required for light‐inhibited germination of Aethionema arabicum seed

New Phytologist, EarlyView.
Summary The germination of most seeds is influenced by the duration, intensity, and quality of light. The seeds of the model plant Arabidopsis are positive photoblastic and require light to germinate. The germination of negative photoblastic seeds is inhibited by white light.

Evolution of petal patterning: blooming floral diversity at the microscale

New Phytologist, EarlyView.
Summary The flowers of angiosperms are extraordinarily diverse. While most floral variation is visible to the naked eye, this diversity goes beyond the macroscale: Floral organs comprise an underappreciated range of cell types that generate a multitude of patterns across their surfaces and give rise to novel structures.
