Noninfectious uveitis (NIU) remains a significant cause of vision impairment, typically managed with glucocorticoids. However, current glucocorticoid implants present considerable side effects, including elevated intraocular pressure and cataracts. To overcome these limitations, we synthesized a novel prodrug, dexamethasone gallate (DG), which possesses the powerful anti-inflammatory ability of dexamethasone (DEX) and exhibits strong antioxidant activity of gallic acid (GA) that helps protect ocular tissues against oxidative stress. DG was formulated into cyclodextrin microparticle suspension eye drops, designed to progressively disintegrate and penetrate ocular tissues effectively. In experimental autoimmune uveitis (EAU) models, DG suspension eye drops demonstrated comparable therapeutic efficacy to conventional DEX eye drops at reduced dosages, significantly reducing anterior and posterior ocular inflammation. Notably, DG formulations substantially minimized intraocular pressure elevation and glucocorticoid-related adverse effects. These findings support the potential of DG suspension eye drops as a safer, efficient, and patient-friendly therapeutic alternative for treating NIU.
期刊介绍:
Colloids and Surfaces B: Biointerfaces is an international journal devoted to fundamental and applied research on colloid and interfacial phenomena in relation to systems of biological origin, having particular relevance to the medical, pharmaceutical, biotechnological, food and cosmetic fields.
Submissions that: (1) deal solely with biological phenomena and do not describe the physico-chemical or colloid-chemical background and/or mechanism of the phenomena, and (2) deal solely with colloid/interfacial phenomena and do not have appropriate biological content or relevance, are outside the scope of the journal and will not be considered for publication.
The journal publishes regular research papers, reviews, short communications and invited perspective articles, called BioInterface Perspectives. The BioInterface Perspective provide researchers the opportunity to review their own work, as well as provide insight into the work of others that inspired and influenced the author. Regular articles should have a maximum total length of 6,000 words. In addition, a (combined) maximum of 8 normal-sized figures and/or tables is allowed (so for instance 3 tables and 5 figures). For multiple-panel figures each set of two panels equates to one figure. Short communications should not exceed half of the above. It is required to give on the article cover page a short statistical summary of the article listing the total number of words and tables/figures.
