Developing oral drug delivery systems is promising for ulcerative colitis (UC). However, the key challenges, including formulation degradation under harsh gastric conditions, poor targeting efficiency, and limited colonic residence, lead to therapeutic efficacy that still needs be tackled. Effective treatment requires a safe, efficacious, enzyme- pH-responsive, biomucoadhesive system overcome these challenges. Therefore, we have developed chitosan-armored 1,2-dimyristoyl-sn-glycero-3-phosphoglycerol (DMPG) nanoliposomes amalgamated with synthesized beta-sitosterol-sinapic acid (Be-S) conjugate, further encapsulated 3,4-methylenedioxy-β-nitrostyrene (MNS) as NLRP3 inhibitor, termed C@MN@DMBe-S, limitation of free MNS sinapic acid. Formulated by thin-film hydration method processed through extrusion, unilamellar liposomes demonstrated structural stability mucoadhesive properties due chitosan coating. This configuration protected from acidic environment allowed retention in inflamed colon 48 h. The enzyme-responsive C@MN@DMBe-S nanoliposome releases at site via esterase activity, providing sustained controlled release MNS. synergistic action delivers antioxidant anti-inflammatory effects while influencing gut microbiota composition releasing short-chain fatty acids. Moreover, investigations revealed exhibited superior compared when administered orally. effectively downregulated NF-κB, NLRP3, Caspase-1, IL-1β expression upregulating MUC5AC expression, indicating enhanced protective thereby promoting mucosal healing. In addition, was found regulate immune cell downregulate neutrophil infiltration. armor- strategy elucidates impact nanomedicines on mitigating UC an effective treatment.

Abstract: Inflammatory bowel disease (IBD), including Crohn's and ulcerative colitis, primarily arises from defects in the colonic barrier, imbalances of gut microbiota, immune response issues. These complex causes make it difficult to achieve a complete cure. Patients with IBD frequently experience recurrent abdominal pain bloody diarrhea, while severe cases may result intestinal obstruction, perforation, cancer. Lifelong maintenance therapy thus be needed manage these symptoms; however, traditional drugs, such as 5-aminosalicylic acid, glucocorticoids, immunosuppressants, biological agents, are often associated problems poor solubility, instability, ineffective targeting, well causing serious side effects non-target tissues. Nanomaterial drug delivery systems (NDDS) have recently shown great promise optimizing distribution, solubility through biocompatible coatings, enhancing bioavailability via PEGylation reducing effects. formulations can enhance drug's pharmacokinetics by modifying its properties, improve ability cross barriers, boost bioavailability. In addition, NDDS enable targeted delivery, increase local concentrations, efficacy, reduce effects, protecting active molecules recognition protease degradation. The clinical use for treating IBD, requires further research. This review summarizes classification concludes that, despite ongoing challenges, represent an effective treatment approach IBD. summary, therapeutic agents specific cells or tissues, thereby improving efficacy. effectively surmount facilitating efficient sites, which is crucial attaining optimal outcomes. contributes deeper understanding how physicochemical properties influence pharmacological behavior vivo expedite their translation.
