Preparation, characterization, and liver targeting evaluation of a novel sustained-release brucine self-assembled micelle mediated by glycyrrhetinic acid.

Cancer is a serious threat to human life, health and social development. In recent years, nanomicelles, as an emerging drug carrier material, have gradually entered people's field of vision because of their advantages of improving bioavailability, maintaining drug levels, reducing systemic side effects and increasing drug accumulation at target sites. In this study, B-GPSG nano-micelles were prepared by film dispersion hydration method using brucine as model drug and glycyrrhetinic acid-polyethylene glycol-3-methylene glycol-dithiodipropionic acid-glycerol monostearate polymer as nano-carrier.

A novel nano-drug delivery system of glycyrrhetinic acid-mediated intracellular breakable brucine for enhanced anti-hepatitis B efficacy.

Glycyrrhetinic acid-mediated brucine self-assembled nanomicelles enhance the anti-hepatitis B properties of brucine by improving its water solubility, short half-life, toxicity, and side effects. Brucine (B) is an indole alkaloid extracted from the seeds of (Loganiaceae). To assess the efficacy of the Brucine-Glycyrrhetnic acid-Polyethylene glycol-3,3'-dithiodipropionic acid-Glycerin monostearate (B-GPSG) in treating hepatitis B, its potential to protect against acute liver injury caused by d-galactosamine and its anti-hepatoma activities were studied.
