abstract: The ability to manipulate the interaction between small molecules and biological macromolecules towards the study of disease pathogenesis has become a very important part of research towards treatment options for various diseases. The work described here shows both the use of DNA oligonucleotides as carriers for a nicotine hapten small molecule, and the use of microsomes to study the stability of compounds derived to treat mitochondrial diseases.
Nicotine addiction is a worldwide epidemic because nicotine is one of the most widely used addictive substances. It is linked to early death, typically in the form of heart or lung disease. A new vaccine conjugate against nicotine held within a DNA tetrahedron delivery system has been studied. For this purpose, several strands of DNA, conjugated with a modified dTpT having three or six carbon atom alkynyl linkers, have been synthesized. These strands have later been conjugated to three separate hapten small molecules to analyze which conjugates formed would be optimal for further testing in vivo.
Mitochondrial diseases are hard to treat, given that there are so many different variations to treat. There is no one compound that can treat all mitochondrial and neurodegenerative diseases; however, improvements can be made to compounds currently under study to improve the conditions of those afflicted. A significant issue leading to compounds failing in clinical trials is insufficient metabolic stability. Many compounds have good biological activity, but once introduced to an animal, are not stable enough to have any effect. Here, several synthesized compounds have been evaluated for metabolic stability, and several showed improved stability, while maintaining biological activity. / Dissertation/Thesis / Doctoral Dissertation Chemistry 2016
