Relative Reaction Rates Of The Amino Acids Cysteine, Methionine, And Histidine With Analogs Of The Anti-Cancer Drug Cisplatin, Cynthia A. Tope
Relative Reaction Rates Of The Amino Acids Cysteine, Methionine, And Histidine With Analogs Of The Anti-Cancer Drug Cisplatin, Cynthia A. Tope
Mahurin Honors College Capstone Experience/Thesis Projects
We are studying the reaction of analogs of the anticancer drug cisplatin with amino acids that differ in size and shape. The reaction of cisplatin with proteins likely precedes reaction with DNA in the body, forming a variety of products that may be toxic to the human body. The size and shape of the platinum(II) complexes often affects the rate of reaction with proteins, more so than with DNA. In this study, triamine cisplatin analogs are reacted with the amino acids cysteine, methionine, and histidine simultaneously. These reactions are monitored by NMR spectroscopy. The effect of the bulk of the …
Reaction Rates Of Amino Acids With Derivatives Of The Anticancer Drug Cisplatin, Celia Jess Whelan
Reaction Rates Of Amino Acids With Derivatives Of The Anticancer Drug Cisplatin, Celia Jess Whelan
Mahurin Honors College Capstone Experience/Thesis Projects
We are studying reactions of cisplatin derivatives, which differ in both size and shape, with various amino acids. When reaction with DNA occurs, apoptosis is observed, ideally leading to termination of the cancer. Due to the affinity of cisplatin for sulfur-containing amino acids, reaction with proteins may occur prior to access to the DNA, producing a large array of products, which could potentially be toxic to the human body. Both the size and shape of the platinum complexes often affect the reactions with protein targets more so than with DNA targets. By performing reactions of specific amino acids targets with …
