Synthetic Pathways For Potential Platinum 1,10-Phenanthroline Compounds, Jacob Young
Synthetic Pathways For Potential Platinum 1,10-Phenanthroline Compounds, Jacob Young
Mahurin Honors College Capstone Experience/Thesis Projects
There are extremely important uses for platinum when it comes to the treatment of cancers and dementias. One potential therapeutic combines platinum with a structure known as phenanthroline. This platinum phenanthroline structure is normally extremely water-insoluble, rendering it difficult to study and use in biological systems. The Williams’ Biochemistry Laboratory endeavored to find a simpler synthetic pathway for a water-soluble phenanthroline product. While unsuccessful in identifying a product as of yet, many synthetic pathways have been ruled out, and more hypothetical pathways are being formulated for testing.
Among the strategies analyzed are varying solvent, reagents, apparatus, methodology, and temperature in …

This work was intended to develop self-assembly lipids for incorporating G-protein coupled receptors (GPCRs) in order to improve the success rate for nuclear magnetic resonance spectroscopy (NMR) structural elucidation. We hereby report the expression and purification of uniformly 15N-labeled human cannabinoid receptor-2 domain in insect cell media. The domain was refolded by screening several membrane mimetic environments. Different q ratios of isotropic bicelles were screened for solubilizing transmembrane helix 6, 7 and 8 (TMH67H8). As the concentration of dimyristoylphosphocholine (DMPC) was increased such that the q ratio was between 0.16 and 0.42, there was less crowding in the cross peaks …

The platinum compound Cl [Chloro[N,N-diethyldiethylenetriamine] Platinum(II) Chloride] was synthesized and reacted with N-acetylmethionine (N-AcMet) and guanosine 5’-monophosphate (5’-GMP). Previous experiments show that N-AcMet reacts kinetically faster with the central platinum atom and that 5’-GMP bonds slower yet stronger. When Cl was reacted with N-AcMet the N-AcMet displaced the chloride ion as expected. When Cl was reacted with 5’-GMP the 5’-GMP binds to the chloride ion and the reaction is finished. Yet, when 5’-GMP was added in the solution already containing N-AcMet, the N-AcMet was not displaced as predicted. Through 1H NMR Spectroscopy and Mass Spectrometry we observed that …
