Isoastilbin Usage And Synthesis

Description

Isoastilbin (IA) is a dihydroflavonol glycoside compound, and studies have shown that IA has a good effect on antioxidants.

Biological Activity

Isoastilbin, a dihydroflavonol glycoside compound in Rhizoma Smilacis glabrae and Astragalus membranaceus. It inhibits glucosyltransferase (GTase) with IC50 value of 54.3 μg/mL, and also inhibits tyrosinase activity. It has neuroprotective, antioxidant, antimicrobial and anti-apoptotic properties and can be used in Alzheimer's disease research.

target

IC50: 54.3 μg/mL (Glucosyltransferase (GTase)
