Analysis Of Drug-Protein Interactions During Diabetes By High-Performance Affinity Chromatography, Pingyang Tao Apr 2019

Analysis Of Drug-Protein Interactions During Diabetes By High-Performance Affinity Chromatography, Pingyang Tao

Student Research Projects, Dissertations, and Theses - Chemistry Department

High-performance affinity chromatography (HPAC) is a type of liquid chromatography in which solutes are separated based on their binding to a stationary phase that is a biologically-related agent. Sulfonylurea drugs have significant binding to proteins in blood, with most of this binding is believed to occur with human serum albumin (HSA). HSA is known to be modified as a result of the high serum levels of glucose that is present during diabetes, which may also alter the function of HSA as a binding agent for many drugs in circulation. Some modifications of HSA that can occur during diabetes involves early ...


Development Of Novel Therapeutic Approaches: (I) Targeting Allergic Responses To Peanuts And (Ii) Inhibition Of Dpp-Iv Enzyme Involved In Diabetes, Savan V. Patel Jun 2017

Development Of Novel Therapeutic Approaches: (I) Targeting Allergic Responses To Peanuts And (Ii) Inhibition Of Dpp-Iv Enzyme Involved In Diabetes, Savan V. Patel

Theses and Dissertations

There is an increase in prevalence of peanut allergy, especially in the western world. The only current treatment for peanut allergy is avoidance of peanut from diet and contact. Additionally, there is currently no specific vaccine that can be taken to decrease peanut allergies. The method of desensitizing a person allergic to peanut allergy is deemed unsafe as the smallest amount of peanut can trigger an anaphylaxis reaction. Thus, various allergoids were created by modifying major peanut protein allergen Ara h2 using various cross-linkers and modification agents in order to disrupt the binding surface epitopes of the antigen to antibody ...


Ligands Of Therapeutic Utility For The Liver X Receptors., Rajesh Komati, Dominick Spadoni, Shilong Zheng, Jayalakshmi Sridhar Jan 2017

Ligands Of Therapeutic Utility For The Liver X Receptors., Rajesh Komati, Dominick Spadoni, Shilong Zheng, Jayalakshmi Sridhar

Faculty and Staff Publications

Liver X receptors (LXRs) have been increasingly recognized as a potential therapeutic target to treat pathological conditions ranging from vascular and metabolic diseases, neurological degeneration, to cancers that are driven by lipid metabolism. Amidst intensifying efforts to discover ligands that act through LXRs to achieve the sought-after pharmacological outcomes, several lead compounds are already being tested in clinical trials for a variety of disease interventions. While more potent and selective LXR ligands continue to emerge from screening of small molecule libraries, rational design, and empirical medicinal chemistry approaches, challenges remain in minimizing undesirable effects of LXR activation on lipid metabolism ...


Zn(Ii), Cu(Ii), Sn(Ii), And Ni(Ii) And Other Metal Cations Do Not Prevent The Aggregation Of Hiapp, Charles Hoying May 2016

Zn(Ii), Cu(Ii), Sn(Ii), And Ni(Ii) And Other Metal Cations Do Not Prevent The Aggregation Of Hiapp, Charles Hoying

Honors Thesis

The Zn(II) metal ion has been shown to interact with Islet Amyloid Polypeptide (IAPP), a protein implicated in the progression of Type II Diabetes Mellitus, in such a way as to prevent the protein from aggregating into toxic fibers. We set out to find whether other metal ions might similarly prevent IAPP aggregation. Using Thioflavin T (ThT) spectroscopic assays, which measure fluorescence of ThT upon binding to aggregated IAPP, we observed a decrease in aggregation when incubated with Zn(II), Cu(II), Ni(II), and Sn(II). Atomic Force Microscopy (AFM), which can visualize fibril formation, revealed that the ...
