Effects Of Binding Affinity Between Bovine Serum Albumin And Platinum Drugs, Nathan Puckett
Masters Theses & Specialist Projects
Platinum complex drugs such as cisplatin have been used as highly successful chemotherapy drugs since the 1970s. We are interested in how the ligands attached to cisplatin analogs influences their reactivity with biologically relevant targets along with time and amount. For this study, reactions were conducted to determine the reactivity between different platinum compounds and the protein bovine serum albumin. Various platinum compounds with different ligands were reacted in varying amounts with albumin in ammonium acetate buffer for either 1 hour, 4 hours, or 24 hours. Each reaction was quenched after the designated reaction time by dialysis and the platinum …

Mahurin Honors College Capstone Experience/Thesis Projects
We have reacted [Pt(Me4en)(D2O)2]2+ [Me4En=N,N,N’N’-tetramethylethylenediamine] with Selenomethionine (SeMet), Methionine (Met), and Methylselenocysteine (MeSeCys). When MeSeCys was reacted with [Pt(Me4en)(D2O)2]2+, we observed both stereoisomers of Se,N chelates, as well as [Pt(Me4en)(MeSeCys)Cl]+ from 1H NMR Spectroscopy; the latter formed due to the presence of Cl- in the solution. Both isomers of the chelate seemed to form proportionally to one another, not favoring a specific stereoisomer. Eventually the [Pt(Me4en)(MeSeCys)Cl]+ products became Se,N chelates. We incubated SeMet with …
