Isolation And Total Synthesis Of Sigma-2 Ligands From Marine Cyanobacteria, Andrea Hough
Isolation And Total Synthesis Of Sigma-2 Ligands From Marine Cyanobacteria, Andrea Hough
Electronic Theses and Dissertations
Cyanobacteria have been studied for over 50 years as a source of new antibiotics, antiviral, and anticancer drugs. The research described in this dissertation investigates marine cyanobacteria as a source of natural products with activity within the central nervous system and with cytotoxicity against breast cancer cells. Barbamide (1) is a known cyanobacterial metabolite that has been re-isolated from a variety of species and collection sites suggesting broad utility as a signaling molecule. Utilizing the psychoactive drug screening program, we screened barbamide for CNS activity and found that barbamide exhibited affinity for the kappa opioid receptor (KOR) and …
Long-Acting Intraductal Drug Delivery Systems For The Breast, Mibin Joseph
Long-Acting Intraductal Drug Delivery Systems For The Breast, Mibin Joseph
Electronic Theses and Dissertations
Breast cancer is the second most commonly diagnosed cancer in women in the US. Ductal carcinoma in situ (DCIS) is a premalignant lesion that has not metastasized through the regional lymph nodes to other organs. Currently, all breast cancers including localized breast cancers are treated with the same aggressive therapy. Localized drug delivery by direct intraductal injections into the mammary ducts can achieve high drug concentration at the target site. However, poor retention of drugs in the ducts limits the successful translation of this approach to the clinic. To this end, the main goal of this dissertation is to develop …
Role Of Human Arylamine N-Acetyltransferase 1 In Tumorigenesis And Cancer Biology., Marcus William Stepp
Role Of Human Arylamine N-Acetyltransferase 1 In Tumorigenesis And Cancer Biology., Marcus William Stepp
Electronic Theses and Dissertations
Human arylamine N-acetyltransferase 1 (NAT1) is a well-known phase II metabolic enzyme that has been associated with carcinogenesis. Its role in the biotransformation of aromatic and heterocyclic amine carcinogens has been investigated for many years, but more recent investigations focus on a possible endogenous role of human NAT1 in cancer initiation and progression. To further explore and understand possible endogenous roles for NAT1, we conducted in vitro enzymatic reactions, in vivo studies using homozygous high (rapid) or low (slow) NAT2 activity congenic F344.WKY rats, and genetically modified human breast cancer cell lines. Human NAT1 and rodent NAT2 hydrolyzed acetyl-coenzyme …
Management Of Breast Cancer In The Medicaid Population, Rohan Mahabaleshwarkar
Management Of Breast Cancer In The Medicaid Population, Rohan Mahabaleshwarkar
Electronic Theses and Dissertations
Breast cancer is the second most comcancer and the second leading cause of cancer-related death among women. The current project examined some key issues important for effective breast cancer management in the Medicaid population. Medicaid is one the largest healthcare insurance systems in the US providing coverage to more than 60 million low-income individuals. As a part of this project, three studies were conducted. The first study determined the healthcare burden associated with breast cancer in the form of healthcare use (inpatient, outpatient, and emergency room [ER] visits) and costs associated with the condition in the Medicaid population. Significant healthcare …
