Engineering A Mutation In The Heparin Binding Pocket Of The Human Fibroblast Growth Factor, Roshni Patel
Chemistry & Biochemistry Undergraduate Honors Theses
Fibroblast growth factors (FGFs) are family of proteins that belong to a group of growth factors that are found in mammals and play an important role in angiogenesis, differentiation, organogenesis, and tissue repair. In summary, their main functionality is involved in cell division and proliferation. Because FGFs plays such a vital role in cell proliferation, they are mainly involved in the process of wound healing and injuries. FGF binds to its ligand, heparin—a heavily sulfated glycosaminoglycan. The binding of heparin to FGF occurs through electrostatic interactions, specifically between the negatively charged sulfate groups on heparin and positively charged residues such …

Probing Allosteric, Partial Inhibition Of Thrombin Using Novel Anticoagulants,

Probing Allosteric, Partial Inhibition Of Thrombin Using Novel Anticoagulants, Stephen S. Verespy Iii
Theses and Dissertations
Thrombin is the key protease that regulates hemostasis; the delicate balance between procoagulation and anticoagulation of blood. In clotting disorders, like deep vein thrombosis or pulmonary embolism, procoagulation is up-regulated, but propagation of clotting can be inhibited with drugs targeting the proteases involved, like thrombin. Such drugs however, have serious side effects (e.g., excessive bleeding) and some require monitoring during the course of treatment. The reason for these side effects is the mechanism by which the drugs’ act. The two major mechanisms are direct orthosteric and indirect allosteric inhibition, which will completely abolish the protease’s activity. Herein we sought an …

Chemoenzymatic Studies To Enhance The Chemical Space Of Natural Products, Jhong-Min Chen
Theses and Dissertations--Pharmacy
Natural products provide some of the most potent anticancer agents and offer a template for new drug design or improvement with the advantage of an enormous chemical space. The overall goal of this thesis research is to enhance the chemical space of two natural products in order to generate novel drugs with better in vivo bioactivities than the original natural products.
Polycarcin V (PV) is a gilvocarcin-type antitumor agent with similar structure and comparable bioactivity with the principle compound of this group, gilvocarcin V (GV). Modest modifications of the polyketide-derived tetracyclic core of GV had been accomplished, but the most …

Polymer Interactions With Nucleic Acids Under Various Physiological Conditions, Matthew S. Obrzut
Williams Honors College, Honors Research Projects
The goal of this project is to improve our understanding of nucleic acid interactions with cationic polymers with the theory that the polymers could protect the nucleic acids from degradation caused by biological enzymes. We seek to understand what the limitations of the cationic polymers are which, in this case, is mainly polymer-DNA compatibility. This experiment utilized peptide-dextran hybrid polymers with differing functionalizations to condense anionic nucleic acids into nanometer-sized polyplexes. Techniques of dynamic light scattering and zeta-potential were utilized to determine the particle sizes and surface charges of polyplexes.
In this experiment, dextran with a molecular weight of 20 …

The overall purpose of this preparatory course textbook is to help students familiarize with some terms and some basic concepts they will find later in the Human Anatomy and Physiology I course.
The organization and functioning of the human organism generally is discussed in terms of different levels of increasing complexity, from the smallest building blocks to the entire body. This Anatomy and Physiology preparatory course covers the foundations on the chemical level, and a basic introduction to cellular level, organ level, and organ system levels. There is also an introduction to homeostasis at the beginning.

A new class of nucleoside analogues were synthesized using cyclic dipeptides and modified 2′-deoxyfuranoribose sugars to introduce flexibility by peptides in place of common nucleoside bases and to determine their biological properties. The synthesis was carried out by coupling of a protected ribose sugar with synthesized dipeptides in the presence of hexamethyldisilazane and trimethylsilyltriflate. The final products were characterized by NMR and high-resolution MS-TOF spectroscopy. The compounds were evaluated for anti-HIV activities. 1-(4-Azido-5-(hydroxymethyl)tetrahydrofuran-2-yl)-3,6-diisopropylpiperazine-2,5-dione (compound 14) containing 3- and 6-isopropyl groups in the base and 3′-azide (EC50 = 1.96 μmol/L) was the most potent compound among all of the synthesized analogs.

Synthesis Of The Disaccharide Αgal(1,4)Βgal Related To Trypanosoma Cruzi And Its Conjugation To A Protein, Erika Y. Monroy, Igor C. Almeida, Katja Michael*
COURI Symposium Abstracts, Summer 2012
The disaccharide αGal(1,4)βGal was synthesized by Schmidt’s trichloroacetimidate method. α-Stereoselectivity was achieved by the sterically demanding 4,6-di-tert-butyl-silylidene protecting group in the glycosyl donor. The disaccharide was equipped with an allyl group that allowed for the installation of a thiol functionality, which was used for conjugation to the maleimide-derivatized carrier protein keyhole limpet hemocyanin (KLH). Among other oligosaccharides with terminal a-galactosyl moieties this disaccharide could potentially exist on the cell surface of the parasite Trypanosoma cruzi (T. cruzi), which is the causative agent of Chagas disease. As of today no effective vaccine has been developed for Chagas disease. The …
