The Discovery And Characterization Of Novel Potent 5-Substituted 3, 3’, 4’, 7-Tetramethoxyflavonoid Dna Triplex Specific Binding Ligands, Vanessa Marie Rangel
The Discovery And Characterization Of Novel Potent 5-Substituted 3, 3’, 4’, 7-Tetramethoxyflavonoid Dna Triplex Specific Binding Ligands, Vanessa Marie Rangel

Chemotherapy works by killing fast dividing cells. Unfortunately, these drugs are not specific to cancer tissue and can damage normal cells. Chemotherapy is like taking poison and hoping it kills the cancer cells before it kills you. As an alternative, many researchers have investigated the use of antigene therapy to selectively target cancer causing genes to avoid off target effects. Although promising, the theory is limited by the stability of the triplex structure. Here, we report the discovery of potent triplex binding ligands derived from the natural product quercetin. Chemical derivatives of 5-substituted 3, 3’, 4’, 7-tetramethoxyquercetin derivatives were characterized …
Impact Of 17-Beta Estradiol And Moderate-Intensity Exercise On Mesenteric Arterial Function Of Uc Davis Type-2 Diabetes Mellitus Rats, Md Rahatullah Razan
Impact Of 17-Beta Estradiol And Moderate-Intensity Exercise On Mesenteric Arterial Function Of Uc Davis Type-2 Diabetes Mellitus Rats, Md Rahatullah Razan
University of the Pacific Theses and Dissertations
The studies in this dissertation were designed to investigate the impacts of estrogen (17-β estradiol/E2) and moderate-intensity exercise (MIE) on the mesenteric arterial (MA) function of the University of California Davis type-2 diabetes mellitus (UCD-T2DM) Rat model. Our recent report suggests that diabetes impairs MA vasorelaxation in both sexes of the UCD-T2DM model. Particularly, we reported that MA from prediabetic male rats showed a greater impairment compared to that in prediabetic females. However, when females become diabetic, they exhibit a greater vascular dysfunction than males. Therefore, the aim of the first study was to investigate whether female sex hormone, specifically …
Predicting Aqueous Solubility Of Pharmaceutical Agents By Solid Dispersion Prepared By Solvent Evaporation Method, Karthik Reddy Patlolla
Predicting Aqueous Solubility Of Pharmaceutical Agents By Solid Dispersion Prepared By Solvent Evaporation Method, Karthik Reddy Patlolla
University of the Pacific Theses and Dissertations
Solubility of active pharmaceutical agents is a crucial process that determines drug absorption and ultimately its bioavailability. Many of the new therapeutically beneficial compounds discovered are lipophilic requiring various solubility enhancement strategies to improve their solubility. Among these strategies, solubility enhancement using solid dispersions is a leading method. To obtain a desirable increase in the solubility of a poorly-soluble compound, a good understanding of the molecular descriptors influencing the enhancement of solubility is essential. Therefore, the major research objective was to determine the descriptors which significantly influence the solubility enhancement by solid dispersions. After enhancing the solubility of selected poorly-soluble …
Turning Stealth Liposomes Into Cationic Liposomes For Anticancer Drug Delivery, Vijay Gyanani
Turning Stealth Liposomes Into Cationic Liposomes For Anticancer Drug Delivery, Vijay Gyanani
University of the Pacific Theses and Dissertations
Targeting the anticancer agents selectively to cancer cells is desirable to improve the efficacy and to reduce the side effects of anticancer therapy. Previously reported passive tumor targeting by PEGylated liposomes (stealth liposomes) have resulted in their higher tumor accumulation. However their interaction with cancer cells has been minimal due to the steric hindrance of the PEG coating. This dissertation reports two approaches to enhance the interaction of stealth liposomes with cancer cells. First, we designed a lipid-hydrazone-PEG conjugate that removes the PEG coating at acidic pH as in the tumor interstitium. However, such a conjugate was highly unstable on …
The Development Of A Course Of Study In Fda Drug Regulatory Procedures, Robin Adele Wills
The Development Of A Course Of Study In Fda Drug Regulatory Procedures, Robin Adele Wills
University of the Pacific Theses and Dissertations
It is the purpose of this thesis to develop a course of study for pharmacy schools on drug regulation by the Food and Drug Administration (FDA). A summarization of the history of the development of the Food and Drug Administration (FDA) and of pharmacy education reveals a lack of interface between the two. The necessity for the interface of pharmacy education and the agency which has significant control over the products forming the basis of the pharmacy profession will be made apparent. A period of residency through which the course of study on drug regulation by the FDA was to …

The father of coordination chemistry was Alfred Werner (1866- 1919). Werner's theory was largely responsible for the renewed interest in, and rapid growth of, inorganic chemistry around the turn of the century. He postulated that there were two types of valence, primary and secondary, which correspond, in modern terminology, to oxidation state and coordination number. The primary valences must be either negative ions, neutral molecules or, occasionally even, positive ions (11). He also postulated that the secondary valences are directed in space about the central ion, not only in the solid state, but also when the complex is in solution. …

Prom the dawn of history man has searched among the natural products of his environment for substances to com- bat his ills. The most widespread of these ills, malaria, today afflicts some 300 million people each year (1). The causative parasite, a protoza, in a somber of the Plasmodium genus and is transmitted through the saliva of the female Anopheles mosquito.
