Natural medicines-derived carbon dots as novel oral antioxidant administration strategy for ulcerative colitis therapy

Journal of Nanobiotechnology, Год журнала: 2024, Номер 22(1)

Опубликована: Авг. 27, 2024

Abstract Background Ulcerative colitis (UC) is a chronic intestinal inflammation, resulting in global healthcare challenge with no real specific medicine. Natural medicines are recognized as potential clinical alternative therapy, but their applications limited by poor solubility and low bioavailability. Results In this work, inspired the natural of ancient China, novel functional carbon dots derived from Magnetite Medicated Leaven (MML-CDs) were synthesized hydrothermal method, confirmed ultrasmall nano-size (3.2 ± 0.6 nm) Fe doped surface structure, thereby excellent gastrointestinal stability, remarkable capabilities eliminating ROS, highly biocompatibility. With external stimuli, oral administration MML-CDs demonstrated obvious alleviation to UC. Further experiments pointed that could improve hemostasis capability, suppress inflammation reactions oxidative stress, up-regulate expression tight junction proteins. Furthermore, also showed well regulation dysbiosis flora. Conclusion Overall, above evidence reveals green-synthesized can significantly alleviate bleeding, inhibit colon repair colonic barrier damage, further regulating flora microenvironment. Our findings provide an efficient therapy strategy for ulcerative colitis. Graphical
