Development Of Novel Therapies For The Treatment Of Inflammatory Bowel Disease, Shrey Kanvinde
Theses & Dissertations
Inflammatory bowel disease (IBD) is a chronic and remittent inflammation of the gastrointestinal tract (GIT). Despite extensive research efforts, there is no cure nor a well-defined pathogenesis for IBD. Loss of epithelial barrier function, increased colonic immune cell infiltration and upregulation of pro-inflammatory cytokines are the hallmarks of IBD. Despite treatments like painkillers, aminosalicylates, steroids, and biologics, almost 70% patients require surgery at least once in their life time. The main limitation with most of the current treatments is they are either absorbed systemically or administered systemically resulting in adverse side effects. As a result, there is a huge unmet …

Electronic Theses and Dissertations
Systemic administration of chemotherapeutics is associated with various side effects deriving from accumulation in off-target sites and acute toxicity of the drugs. In the past decade, engineering targeted drug delivery platforms arose as a novel paradigm to overcome such obstacles and ultimately achieve advanced forms of chemotherapy. This thesis reports successful syntheses of l-RSP, a redox-sensitive self-immolative polymer, and DNS-SN38, thiol-sensitive SN-38 prodrug, as potential candidates for targeted drug delivery platforms. By covalently conjugating a redox-trigger (p-nitrobenzyl alcohol) and self-immolative linker (p-hydroxybenzyl alcohol) to the cyclization spacer (n-2-(hydroxyethyl)ethylene diamine), a novel self-immolative monomer was obtained. Polymerization of the respective monomer …
