Target Based Design And Synthesis Of Heterocycles In The Potential Treatment Of Cancer And Opportunistic Infection, Shruti Choudhary

Electronic Theses and Dissertations

Dose limiting toxicity and development of multidrug resistance by the tumors are the major limitations of current cancer chemotherapy. Microtubule targeting agents (MTAs) are a structurally diverse set of compounds that disrupt microtubule dynamics and exert their anticancer effect. Among the various classes of such agents, the colchicine site binding agents are particularly important as they circumvent the Pgp and β-III tubulin mediated clinical resistance. These resistance mechanisms, when manifested, are a major reason for the failure of clinically used agents such as taxanes and vinca alkaloids. A series of monocyclic pyrimidine analogs were designed and synthesized as colchicine site …

Nitric Oxide Release From Poly(Lactic-Co-Glycolic Acid) Nanoparticles And Titanium Alloy, Nina A. Reger

Electronic Theses and Dissertations

Current methods for the treatment of bacterial infection involve the use of systemic antibiotics, which are high concentrations of antibiotics delivered over a long period time. Unfortunately, the use of systemic antibiotics can cause harmful side effects to the patient and increases the possibility for antibiotic resistance. The delivery of antibiotics or alternative antimicrobial compounds, such as nitric oxide, directly to the site of infection would decrease the amount of antibiotic necessary to treat a bacterial infection.

Poly (lactic-co-glycolic acid)/polyvinyl alcohol nanoparticles and a titanium- aluminum-vanadium metal oxide alloy implant were surface functionalized to deliver nitric oxide. Polymer nanoparticles can …
