Design And Synthesis Of Pyrimidine Based Fused Heterocyclics In The Potential Treatment Of Cancer And Opportunistic Infection, Farhana Islam

Electronic Theses and Dissertations

Dose-limiting toxicities of clinically used agents and development of resistance are two significant limitations in cancer chemotherapy. Microtubule targeting agents (MTAs) are a structurally diverse set of compounds that disrupt microtubule dynamics and exert their anticancer effect. Combination chemotherapy with antiangiogenic agents and microtubule targeting agents has shown an advantage against both these drawbacks. Single agents with dual antiangiogenic activity and cytotoxicity would afford a therapy that circumvents pharmacokinetic problems of multiple agents, avoid drug-drug interactions, lower the drug dose, decrease overlapping toxicities, and delay or prevent tumor cell resistance. The work in this dissertation reflects the progress of fused …

Pharmacological Characterization Of Novel Serotonin Transporter Inhibitors Identified Through Computational Structure-Based Virtual Screening, Michael Wasko

Electronic Theses and Dissertations

Depression is a mental health disorder affecting greater than 350 million people worldwide with roughly 7% of the United States population diagnosed as of 2017. The selective serotonin reuptake inhibitors (SSRIs) have been the mainstay of pharmacotherapies for depression for the last 40 years. The SSRIs target the serotonin transporter (SERT), a monoamine transporter (MAT) responsible for terminating serotonergic neurotransmission. The SSRIs are not perfect therapeutics and suffer from delayed response times, inconsistent efficacy among patients, and often produce intolerable side effects. Therefore, a strong need exists to develop new antidepressants that are more efficacious and have fewer adverse effects. …

Melatonin-Tamoxifen Drug Conjugates As Breast Cancer Drugs: Pharmacological Evaluation In Phenotypically Diverse Breast Cancer Models And Pharmacokinetic Assessment In Liver Microsome And Female Mouse Models, Mahmud Hasan

Electronic Theses and Dissertations

Tamoxifen is a first-generation selective estrogen receptor modulator, which reduces the risk of both invasive and non-invasive breast cancer (BC) as well as tumor recurrence in several clinical trials. However, chronic use of tamoxifen can increase uterine cancer risk and induce tamoxifen resistance. In past studies, melatonin alone reversed tamoxifen resistance induced by light exposure at night in rodents. This study demonstrates that melatonin or melatonin-based ligands (e.g., melatonin-tamoxifen drug conjugates) may be novel BC therapies that are efficacious and free of side effects. To investigate this further, five melatonin-tamoxifen drug conjugates with different linker sizes were synthesized and screened …

Accurate Quantitation Of Hexavalent Chromium For Reference Standard Certification And Quality Control Testing Using Speciated Isotope Dilution Mass Spectrometry, James E. Henderson

Electronic Theses and Dissertations

The ability to perform accurate, repeatable, and defensible elemental and molecular speciated analysis is immensely significant for measurements that support human health, environmental science, and industry. This is especially true since trivalent chromium [Cr(III)] is necessary for proper nutrition, while hexavalent chromium [Cr(VI)] is extremely toxic, genotoxic, and carcinogenic. The main challenges associated with speciated analysis are related to reactive species that are continuously transformed or converted to other species during sample processing. Accurate determination of Cr(III) and Cr(VI) species require a method that is capable of monitoring and correcting for interconversion, bias, and instrumental error. Traditional quantitative methods, such …

The Haven: A Clinical Ethnography Of A Farm-Based Therapeutic Community, Monica Lawson

Electronic Theses and Dissertations

Therapeutic communities are communal spaces where individuals live for an extended period in hopes of recovering from personal crises, or while coping with severe mental illness. They provide a humanistic alternative to inpatient hospitalization. Although they are seldom studied, even less is known about farm-based therapeutic communities in the United States, where communal work is viewed as central to recovery. This dissertation examines the experience of living and working at the Haven. Originally conceived as a farm-based community where suffering individuals could experience reprieve from the demands of the “working world,” and heal by living in community, recent changes in …
