Effects Of Cisplatin Analog Size On The Reaction With Dna Bases, Swathi Nandala May 2013

Effects Of Cisplatin Analog Size On The Reaction With Dna Bases, Swathi Nandala

Masters Theses & Specialist Projects

Cancer is the second leading cause of death in the United States. Cisplatin is one of the well-known anti-cancer agents used to treat testicular and ovarian cancers. It mainly binds to the DNA bases, which leads to cell death. The cytotoxic activity of the cisplatin analogs is due to the interaction of platinum with nucleotides like adenine at N7 or N1 position and guanine at N7 position. Guanine is the primary target for cisplatin analogs whereas adenine is the secondary target. Cisplatin analogs, [Pt(Me5dien)(D2O)]2+[Me5dien = N,N,N ...


Inhibition Of Cysteine Protease By Platinum (Ii) Diamine Complexes, Chaitanya Rapolu Dec 2011

Inhibition Of Cysteine Protease By Platinum (Ii) Diamine Complexes, Chaitanya Rapolu

Masters Theses & Specialist Projects

Chemotherapy is the first line of treatment used in cancer. Chemotherapy drugs such as cisplatin, carboplatin and oxaliplatin are used in treatment. Cisplatin enters the cell through copper transporter CTR1 by passive diffusion and bind to DNA and proteins. Cisplatin is found to inhibit several enzymes targeting cysteine, histidine and methionine residues, which are expected to be responsible for its anticancer activity. A better understanding of how the size and shape and leaving ligands of platinum complexes affect cysteine protease, papain enzyme are studied. This could give new ways to optimize anticancer activity. The activity of papain enzyme was measured ...
