Antigiardial activity of novel triazolyl-quinolone-based chalcone derivatives:when oxygen makes the difference [PDF]
, 2015 Giardiasis is a common diarrheal disease worldwide caused by the protozoan parasite Giardia intestinalis. It is urgent to develop novel drugs to treat giardiasis, due to increasing clinical resistance to the gold standard drug metronidazole (MTZ). New

Synthesis and Preliminary Evaluation of Several Chalcone Derivatives as Sunscreen Compounds
Chemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2019 Four chalcone derivatives were synthesized and pre-evaluated as broad-spectrum UV protector. Chalcones 1-4 showed a wide range of UV absorbance values and moderate molar absorptivity values. Chalcones 3 and 4 showed better photostability than chalcones 1

Plant Biotechnology Journal, EarlyView.ABSTRACT Salvianolic acid is the main active component of Salvia miltiorrhiza and holds significant value in the clinical treatment of myocardial ischemia and hypoxia. Previous studies have shown that salicylic acid (SA) can significantly promote the accumulation of salvianolic acid, but its molecular mechanism remains incompletely understood.

Plant Biotechnology Journal, EarlyView.ABSTRACT Tangeretin has been known as a polymethoxylated flavone conferring both phytoprotection and nutraceutical value, but cryoprotective roles and molecular regulation of tangeretin under abiotic stresses remain largely unexplored. In this study, we demonstrated that cold treatment led to greater accumulation of tangeretin and upregulation of ...

Synthetic and Mechanistic Studies on the Solvent-Dependent Copper-Catalyzed Formation of Indolizines and Chalcones [PDF]
, 2015 Copper nanoparticles supported on activated carbon have been found to catalyze the multicomponent synthesis of indolizines from pyridine-2-carbaldehyde derivatives, secondary amines, and terminal alkynes in dichloromethane; in the absence of solvent ...
