A Biophysical Investigation Of Stability, Ligand Binding, And Iron State Of Cyp102a1, Catherine A. Denning-Jannace

Theses and Dissertations--Chemistry

Cytochrome P450s (CYPs) are cysteine ligated Fe-heme monooxygenases that are found in all domains of life. In mammals, they have a role in xenobiotic metabolism and steroid synthesis, making them a fundamental requirement for survival. In addition, their ability to perform a variety of chemical reactions on an array of substrates makes CYPs highly sought for biotechnical applications such as wastewater remediation, production of potential drug candidates, and creation of drug metabolites. By mutating specific amino acids, these enzymes can be engineered to change their substrate binding profiles and achieve stereo- and regio-specific chemistry. While these mutations are essential to …

Study Of The Mechanism Of Action For Ru(Ii) Polypyridyl Complexes As Potential Anticancer Agents, Yang Sun

Theses and Dissertations--Chemistry

Application of chemotherapeutic agents in current cancer treatment has been limited by adverse effects as poor selectivity results in systemic toxicity; most chemotherapy approaches also experience inherited or acquired drug resistance which lead to reduced treatment outcome. Research efforts have focused on the discovery of novel chemotherapies that overcome the limitations mentioned above. Ru(II) polypyridyl complexes with anti-cancer properties have been extensively studied as traditional cytotoxic agents and photodynamic therapy agents due to their photophysical and photochemical characteristics.

Most research has focused on the design of Ru(II) polypyridyl complexes that have affinities to nucleic acids as inspired by the classic …
