Enzymatic modification of dihydromyricetin by glucosylation and acylation, and its effect on the solubility and antioxidant activity.

Although dihydromyricetin exhibits strong potential for pharmaceutical applications, its limited aqueous solubility, permeability and stability restrict its use. In this work, we have synthesized a series of glucosides and acyl-glucosides of dihydromyricetin that could increase the bioavailability of this molecule. First, the R134A variant of sucrose phosphorylase from catalyzed the formation of three monoglucosides, and the major one was identified as dihydromyricetin 4'--α-D-glucopyranoside (>75% conversion yield).

Heart failure (HF) is a significant event for public health. It has a prevalence between 1-2%, mortality rate between 7-17%, and hospitalization between 32-44%. This implies a risk to health and quality of life, but also great financial efforts for health systems.
