Development And Ex Vivo Characterization Of Enteric Coated Chitosan Beads For Crohn’S Disease Management, Craig Mendonca

University Scholar Projects

Drug delivery is the process of transporting a drug to its site of action. It includes controlled delivery, where the drug is released at the tissue in a regulated manner. Additionally, it includes targeted delivery, where the drug is aimed at a specific tissue or region to avoid unwanted side effects (that would occur if the drug were distributed throughout the body). A cellulose acetate phthalate coated chitosan bead was developed as a formulation for controlled and targeted release of dexamethasone to the ilium and colon. This formulation was determined to be effective in delaying dexamethasone release until the formulation …

Investigating Propargyl-Linked Antifolates In Inhibiting Bacterial And Fungal Dihydrofolate Reductase, Joshua Andrade

Honors Scholar Theses

Antimicrobial agents have been invaluable in reducing illness and death associated with bacterial infection. However, over time, bacteria have evolved resistance to all major drug classes as a result of selective pressure. The advancement of new drug compounds is therefore vital. The Anderson-Wright Lab has focused on developing potent and selective inhibitors of dihydrofolate reductase (DHFR), an enzyme key in cell proliferation and survival, in several pathogenic species. The lab has found that a set of compounds, known as propargyl-linked antifolates, are DHFR inhibitors that are both biologically effective and have strong pharmacokinetic properties.

The efficacy of novel propargyl-linked antifolates …
