Development Of Cytarabine Prodrugs And Delivery Systems For Leukemia Treatment, Bhupender S. Chhikara, Keykavous Parang

Pharmacy Faculty Articles and Research

Importance of the field: Cytarabine is a polar nucleoside drug used for the treatment of myeloid leukemia and non-Hodgkin’s lymphoma. The drug has a short plasma half-life, low stability, and limited bioavailability. Overdosing of patients with continuous infusions may lead to side effects. Thus, various prodrug strategies and delivery systems have been extensively explored to enhance the half-life, stability, and delivery of cytarabine. Among the recent cytarabine prodrugs, amino acid conjugate ValCytarabine and fatty acid derivative CP-4055 (in phase 3 trials) have been investigated for the treatment of leukemia and solid tumors, respectively. Alternatively, delivery systems of cytarabine have …

The Role Of Transdermal Estrogen Sprays And Estradiol Topical Emulsion In The Management Of Menopause-Associated Vasomotor Symptoms., Amy M Egras, Elena Umland

College of Pharmacy Faculty Papers

Vasomotor symptoms (VMS) are among the most bothersome complaints of postmenopausal women. To date, the most widely studied and effective treatment for VMS is hormone replacement therapy, consisting of estrogen (in women without a uterus) or estrogen plus progestin (in women with a uterus). Traditionally, oral estrogens have been used for treatment. However, over the years, additional estrogen formulations have been developed including transdermal patches; vaginal rings, creams, and tablets; and injectable preparations. Two newer formulations are transdermal estrogen spray and estradiol topical emulsion. This review evaluates the current literature assessing the use of these two newer formulations for the …

Role Of Oxidative Reactive Species And Antioxidants In Metabolism And Transport Of Therapeutic Drugs, Svetlana Verenich

Theses and Dissertations

Oxidative stress (OS) is a frequent complication of various disease conditions such as Alzheimer’s and Parkinson’s disease, atherosclerosis, preeclampsia, rheumatoid arthritis, diabetes including gestational diabetes, etc. OS is defined as an imbalance between the production of reactive species and the ability of an organism to detoxify the reactive intermediates and repair the damage. As a result of OS, the excess of reactive species such as oxygen superoxide (O2-), hydroxyl radical (OH), peroxynitrite (ONOO−), 4-hydroxynonenal (4HNE), etc., have a tendency to react with nearby proteins/nucleic acids/lipids changing their functionality or inactivating them completely. The organism has many ways to protect itself …

Drug Release And Pharmacokinetic Properties Of Liposomal Db-67, Yali Liang

University of Kentucky Master's Theses

Sterically stabilized liposomes with saturated lipid as the major lipid component (DSPC:m-PEGDSPE were applied in DB-67 delivery. The drug retention in vitro and pharmacokinetic properties in vivo were investigated. Liposomal DB-67 was cleared faster from the circulation in the larger liposomes (~180 nm) than in the smaller ones (~120 nm), even though DB-67 was retained longer in smaller size liposomes in vitro. Liposomal DB-67 clearance was increased when cholesterol was present in the liposomal composition (40 mole %). It can be attributable to the faster drug release from cholesterol containing liposomes as compared to liposomes without cholesterol. Cholesterol free …

Marine Algae As A Source Of Photosensitisers For Photodynamic Therapy Of Cancer., Tang Yee Voon

Student Works (2010-2019)

Photodynamic therapy (PDT) involves the intravenous administration of a photosensitiser that preferentially localises in cancerous tissues more than the surrounding normal tissues. Subsequent illumination of photosensitiser generates reactive oxygen species that cause irreversible photo-damage to the cancer cells. To date, most photosensitisers that have been approved for clinical use or are currently in clinical trials are cyclic tetrapyrroles which are derived or inspired by naturally occurring chlorophyll and its degradation products. Some non-tetrapyrrolic photosensitisers have also been found in nature suggesting that there are potential photosensitisers with interesting structures in nature. To this end, this thesis outlines the collection of …

Molecular Staging Estimates Occult Tumor Burden In Colorectal Cancer, Alex Mejia, Stephanie Schulz, Terry Hyslop, David S. Weinberg, Scott A. Waldman

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Tumor cells in regional lymph nodes are a key prognostic marker of survival and predictive marker of response to adjuvant chemotherapy in colorectal cancer. However, clinicopathologic techniques to detect lymph node metastases remain imperfect, and ~30% of patients with lymph nodes negative by histology (pN0) develop recurrent disease, reflecting occult metastases that escape detection. These observations underscore an unmet clinical need for accurate approaches to identify occult nodal metastases in colorectal cancer patients. GUCY2C is a receptor whose expression normally is restricted to intestinal epithelial cells, but is universally over-expressed by colorectal cancer cells. A prospective, multicenter, blinded clinical trial …

Inhibition Of Cholesterol Synthesis By Policosanol, Subhashis Banerjee

University of Kentucky Doctoral Dissertations

Cholesterol is an essential component of the cell, but excessive blood levels are a major risk factor for the development of atherosclerotic plaques that can lead to heart disease and stroke, the foremost cause of premature death in Western societies. Policosanol, a mixture of very long chain alcohols derived from sugarcane, has gained considerable attention among the public as safe and effective means to reduce blood cholesterol levels, a belief based on some early clinical studies. My research investigates one possible mechanism by which policosanol might decrease blood cholesterol levels: the inhibition of cholesterol synthesis in the liver. Previous studies …

Modulation Of The Alpha-7 Nicotinic Acetylcholine Receptor Following Experimental Rat Brain Injury Improves Cellular And Behavioral Outcomes, Thomas Matt Woodcock

University of Kentucky Doctoral Dissertations

Traumatic brain injury (TBI) is a leading cause of death and long-term disability worldwide, and survivors are often left with cognitive deficits and significant problems with day to day tasks. To date, therapeutic pharmacological treatments of TBI remain elusive despite numerous clinical trials. An improved understanding of the molecular and cellular response to injury may help guide future treatment strategies. One promising marker for brain injury is the translocator protein (TSPO), which is normally expressed at a low level, but is highly expressed following brain damage and is associated with neuroinflammation. The isoquinoline carboxamide PK11195 binds selectively to the TSPO …

What Is The Impact Of Kentucky’S Pharmacy Recovery Network?, Benjamin Paul Clark

MPA/MPP/MPFM Capstone Projects

Problem Statement: This capstone will focus on Kentucky’s Pharmacy Recovery Network (PRN). In general, professional recovery networks are organizations that act as a liaison between professional state boards and the health professionals who are dealing with substance abuse and addictions that sometimes result in negative consequences to that individual and/or their profession. Instead of a “one-strike and you are out” approach, these organizations recognize that there is a disease process occurring. Thus, as opposed to engaging in strictly punitive measures, a rehabilitative approach is chosen to allow the health professional an opportunity to recover and successfully reenter into their profession. …

Impact Of Levalbuterol Versus Albuterol In Kentucky Medicaid Patients, Velma Henry

MPA/MPP/MPFM Capstone Projects

Problem:

Asthma is a chronic pulmonary disease that occurs in approximately 10 percent of the population worldwide and is associated with a significant increase in direct medical expenditures. Levalbuterol and racemic albuterol are two short-acting β2-agonists (SABA) prescribed for the treatment of asthma. Racemic albuterol has been used for more than 40 years but is associated with several side effects including tremor. When levalbuterol was approved in 2005 its manufacturer and several studies suggested that using levalbuterol results in better respiratory parameters, fewer hospitalizations, less adverse effects and therefore, lower overall treatment costs and hence less need for β-adrenergic agonist …
