Popis: Inflammatory Bowel (IBD) is an umbrella term which includes Crohn's Disease (CD) and Ulcerative Colitis (UC). At present, therapies available for management of the UC includes, corticosteroid, immuno-suppressants and antibiotics are used for mild to moderate UC conditions which can cause nephrotoxicity, hepatotoxicity and cardiotoxicity. Hence, a novel therapeutic candidate having potent anti-inflammatory effect is urgently warranted for the management of UC. Melatonin has emerged as a potent anti-inflammatory agent. However, poor solubility limits its therapeutic potential. Therefore, colon targeted Eudragit-S-100 coated chitosan nanoparticles have been demonstrated to improve melatonin therapeutic efficacy. It was found that melatonin loaded chitosan and colon targeted chitosan nanoparticles had promising anti-inflammatory efficacy in terms of NO scavenging activity in an in-vitro LPS challenged macrophages. Also, colon targeted oral chitosan nano-formulation exhibited remarkable protection in an in vivo UC mice model by improving gross pathological parameters, histo-architectural protection, goblet cell depletion, and immune cells infiltration which can be extrapolated to clinical studies.
