Epigallocatechin gallate (EGCG), a naturally occurring compound known for its multiple health benefits including antioxidant, anti-inflammatory, cancer preventive, and weight management effects, faces challenges due to its inherent instability and limited bioavailability. To address these limitations, our study pioneers an investigation into the unique behavior of EGCG, revealing its degradation into epicatechin (EGC) and gallic acid (GA) during the drug delivery process. In this research, we use fluorescent mesoporous silica nanoparticles (FMSNs) as a sophisticated delivery system for EGCG. This innovative approach aims to not only enhance the stability of EGCG but also regulate its sustained release dynamics to enable prolonged cellular activity. To comprehensively evaluate our novel delivery strategy, we performed assays to assess both the antioxidant potential and its impact on lipid inhibition using Oil Red O. The results not only underscore the potential of FMSN-based nanocarriers for efficient EGCG delivery but also reveal groundbreaking insights into its enzymatic degradation, a previously unexplored facet. This research substantially advances our understanding of EGCG's behavior during delivery and offers a promising avenue for improving its therapeutic efficacy and expanding its applications in health management.
表没食子儿茶素没食子酸酯(EGCG)是一种天然存在的化合物,因其具有多种健康益处而闻名,包括抗氧化、抗炎、防癌和体重管理作用,但由于其固有的不稳定性和有限的生物利用度,面临着挑战。为了解决这些限制,我们的研究率先对EGCG的独特行为进行了调查,揭示了其在药物递送过程中降解为表儿茶素(EGC)和没食子酸(GA)的过程。在这项研究中,我们使用荧光介孔二氧化硅纳米颗粒(FMSNs)作为EGCG的精密递送系统。这种创新方法旨在不仅提高EGCG的稳定性,还调节其缓释动力学,以实现延长的细胞活性。为了全面评估我们的新型递送策略,我们进行了测定,以使用油红O评估抗氧化潜力及其对脂质抑制的影响。结果不仅强调了基于FMSN的纳米载体用于高效递送EGCG的潜力,还揭示了对其酶促降解的开创性见解,这是一个以前未被探索的方面。这项研究极大地推进了我们对EGCG在递送过程中行为的理解,并为提高其治疗效果和扩大其在健康管理中的应用提供了一条有前途的途径。
