AI Technical Summary
Existing technologies for the treatment of liver fibrosis with dexamethasone have problems with systemic side effects and poor targeting, making it difficult to achieve precise targeted delivery and specific release. Furthermore, traditional nanocarriers cannot effectively solve the problems of off-target toxicity and inaccurate drug release.
We designed and synthesized a GGT enzyme-responsive dexamethasone-oligopeptide prodrug for liver fibrosis. By covalently coupling dexamethasone and oligopeptide through Michael addition reaction, we formed self-assembled nanoparticles, which enabled precise self-release of the drug at the site of liver fibrosis lesions and combined anti-inflammatory and immunomodulatory effects.
It achieves precise delivery and specific release of drugs at the site of liver fibrosis, significantly reduces systemic side effects, inhibits the progression of liver fibrosis, and demonstrates more comprehensive therapeutic potential than traditional drugs.
