Physiologically-Based Pharmacokinetic (Pbpk) Modeling For The Preclinical Development Of Spectinamide Antibiotics, Keyur R. Parmar

Theses and Dissertations (ETD)

Despite being an ancient disease caused by Mycobacterium tuberculosis (Mtb) and after decades of research, tuberculosis (TB) still affects millions of people every year worldwide. In 2018, the World Health Organization (WHO) reported that 10 million people developed tuberculosis and 1.5 million died of the disease. With the increase in the multidrug-resistant (MDR) and extensively drug-resistant (XDR) cases, the treatment for TB with the standard first and second-line therapy is becoming increasingly difficult. Therefore, there is an urgent need to find new anti-TB drugs as combination partners of existing and experimental classes of antimicrobial agents to shorten and simplify the …

Vitamin D Levels Affect Survival In A Bcr-Abl Acute Lymphoblastic Leukemia Mouse Model But Do Not Cause Vitamin-Drug Interactions, Kavya Annu

Theses and Dissertations (ETD)

It is a well-established phenomenon that dietary components containing CYP3A inducers or inhibitors if co-administered with drugs that are CYP3A4 substrates lead to marked drug-drug interactions. Because vitamin D is known to regulate intestinal CYP3A expression and gut CYP3A expression plays an important role in pre-systemic metabolism of CYP3A drugs, we determined the impact of vitamin D (VD3) status on systemic exposure and efficacy of chemotherapeutic agents that are CYP3A substrates. We employed VD3 sufficient and deficient mice to perform pharmacokinetics (PK) and anti-leukemic efficacy studies.

First, using hCYP3A4 transgenic mouse model we evaluated the intestinal, hepatic and renal expression …

Tobacco/Hiv-1-Induced Myeloid Cell-Derived Extracellular Vesicles In Hiv-1 Pathogenesis, Sanjana Haque

Theses and Dissertations (ETD)

Introduction. Smoking, which is highly prevalent in people living with HIV/AIDS, has been shown to exacerbate HIV-1 replication, in part via cytochrome P450 (CYP)-induced oxidative stress. CYP enzymes metabolize cigarette smoke condensate (CSC), causing oxidative stress and cytotoxicity. Our previous studies have demonstrated that CSC and specific CSC constituents, benzo(a)pyrene and nicotine, potentially induce CYPs, resulting in higher oxidative stress and subsequent exacerbation of HIV-1 replication in monocytes and macrophages. However, the exact mechanism behind tobacco-induced, oxidative stress-mediated enhancement of HIV-1 replication is still poorly understood. Extracellular vesicles (EVs) have recently gained attention for their unique nature as intercellular messengers …

Translational Pharmacokinetic-Pharmacodynamic Modeling And Simulation In The Development Of Spectinamides, A Novel Class Of Anti-Tuberculosis Agents, Chetan Rathi

Theses and Dissertations (ETD)

New chemotherapeutic agents are urgently needed to control the spread of multidrug-resistant (MDR) and extensively drug-resistant (XDR) forms of tuberculosis, which still remains an important public health challenge globally. Recently, spectinamides have emerged as a novel class of anti-tuberculosis agents that overcomethe native drug efflux. Spectinamides bind to the 30S bacterial ribosomal subunit which interferes with ribosomal translocation, and ultimately results in inhibition of protein synthesis. They have potent in vitro activity against drug resistant Mycobacterium tuberculosis (Mtb), and also demonstrated sustained efficacy in (Mtb)-infected mouse models. Pharmacokinetic (PK)/ pharmacodynamic (PD) analyses play a critical role in identifying …

The Development Of Methods To Account For Physiologic Dynamic Changes And Their Effects On The Pharmacokinetics Of Therapeutic Monoclonal Antibodies And Other Therapeutics, Josiah Thomas Ryman

Theses and Dissertations (ETD)

Physiologic changes in the body can drastically affect the clearance of a medication, and therefore increase the variability in exposure to the medication. Physiologic changes that can have a profound effect on the exposure of a medication can stem from changes CYP enzymes, transport proteins, binding protein expression, organ function, immune reactivity, and health status to name a few; with the focus of this dissertation on the dynamic changes in the ontogeny of MRP2 (an apical liver transport protein) and the dynamic changes caused by an immune response to a therapeutic monoclonal antibody (mAb). Several approaches can be used to …

The Use Of Spectroscopic Techniques In The Characterization Of Mycobacterial Metabolites, Engy Abdelhameed Mahrous

Theses and Dissertations (ETD)

The mycobacterial cell wall metabolites have always imposed great challenges to researchers due to their unusual complexity and structural diversity. A lot of research efforts have been directed towards the evaluation of these metabolites and the role they play in the pathogenesis and virulence of different serious human pathogens including Mycobacterium tuberculosis the causative agent of tuberculosis (TB). In the genomic era, it is crucial to develop new methodologies to analyze these components from a global perspective in a comprehensive and well-validated manner.

Towards this end, we developed a rapid NMR-based approach to produce metabolic profiles in the form of …
