Interaction Of A Platinum Triamine Complex Having A Seven-Membered Chelate Ring With N-Acetyl-Lmethionine And Guanosine 5'-Monophosphate, Jae Ko
Masters Theses & Specialist Projects
In the 1960s, Rosenberg and his colleagues confirmed the anti-cancer activity of cisplatin. Although cisplatin was capable of killing testicular cancer cells there were also serious side effects. It was necessary to find alternate ways of overcoming side effects, and soon many researchers have discovered novel platinum compounds that show similar reactivity. Recently, replacing one chloride group to a heterocyclic amine group showed significant cytotoxicity with a different binding activity than cisplatin. Previously in our lab, [Pt(Me5dien)(NO3)]+ and [Pt(Et2dien)Cl]+ have been synthesized and reacted with NAcetyl- L-methionine (N-AcMet) and Guanosine 5’-monophosphate (5’-GMP) showed unusual reactivity. Unlike most previously studied platinum …
Effects Of Binding Affinity Between Bovine Serum Albumin And Platinum Drugs, Nathan Puckett
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 …

The Reaction Of A Water Soluble Platinum Compound With Methionine And Derivatives, Yueh Ying Liao
Masters Theses & Specialist Projects
Water soluble platinum complexes are a recent area of emphasis of cisplatin chemistry. The water soluble complexes could have a reduced toxicity compared with cisplatin. Oxaliplatin, which has an oxalate leaving group, has previously been shown to have less nephro-toxicity and higher water solubility than cisplatin. [Pt(en)(oxalate)] (en = ethylenediamine) has been prepared from Pt(en)Cl2 and silver oxalate. This complex has been reacted with methionine and N-acetylmethionine at different molar ratios. At high Pt: methionine ratios, chelates with the sulfur and nitrogen atoms of the methionine are dominant; at lower Pt: methionine ratios, a bis-methionine product is formed. The en …
