Synthesis Of Resveratrol Ester Derivatives Using Selective Enzymatic Hydrolysis., Marian Osei-Mensah

Electronic Theses and Dissertations

Resveratrol, a naturally derived stilbene, is an interesting compound mostly talked about recently because for its anti-cancer properties. Unfortunately it has some shortcomings due to its low bioavailability and low solubility in water. For this reason, my research is to overcome resveratrol's drawbacks by improving its bioavailability and hydrophilicity. My research is focused on syntheses of novel derivatives of resveratrol such as 3, 5-di-O-isobutyroyl resveratrol and 3, 5-di-O-hexanoyl resveratrol using lipase catalyzed hydrolysis. Therefore, the tri-acylated resveratrols 3, 5, 4'-tri-O-isobutyroyl resveratrol and 3, 5,4'-tri-O-hexanoyl resveratrol were first synthesized.

3,5,4'-tri-O-isobutyroyl resveratrol and 3,5,4'-tri-O-hexanoyl resveratrol were then hydrolyzed using lipase (C. …

Drug Design, Biological Activity, And Metabolic Consequences Of Cytotoxic Platinum Compounds: Utilizing Fluorescent Tagging To Understand Drug Action And Metabolism, Brad Benedetti

Theses and Dissertations

Platinum drugs are among the most commonly used chemotherapeutics for the treatment of testicular, head and neck, ovarian, small cell lung, and colorectal carcinomas. Although the current set of platinum chemotherapeutics has proven somewhat successful, the overall success of platinum based drugs is limited due to acquired drug resistance and a limited range of tumor types that are treatable with the current regime. The development of novel cytotoxic platinum based compounds, both trans- and polynuclear, provides for the promising treatment of clinical platinum drug resistant tumors. While the cytotoxic activity of platinum drugs provides for a hopeful outlook, the ultimate …

Synthesis And Analytical Evaluation Of Folate Conjugates For Use In Cancer Cell Detection, Rakeshkumar V. Desai

All Capstone Projects

Folate receptors have two glycosyl phosphatidylinositol anchored isomers, alpha and beta. Folate receptor alpha binds with high affinity for folic acid and act as a receptor for mediated transport of folate into the cells. Folate is necessary for DNA metabolism and thus it is speculated that rapidly dividing cancer cells have an increased necessity for folic acid. Folate receptor alpha levels eminent in specific malignant diseases (like solid tumors and leukemia) and thus folate receptors serve in the detection of FR+ (Folate receptor positive) and diagnosis of cancers.
