WebMay 26, 2024 · Cisplatin is a widely used drug in the treatment of various solid tumors, such as ovarian cancer. However, while the acquired resistance significantly limits the success of therapy, some tumors, such as colorectal cancer, are intrinsically insensitive to cisplatin. Only a small amount of intracellular platinum binds to the target-genomic DNA. WebThus many anticancer drugs are designed to target DNA, and cisplatin is one most effective DNA-damaging agents. Its mode of action is relatively simple: The platinum atom binds to two neighboring DNA bases called guanines and cross-links them, thus widening the DNA duplex structure. the penguin dictionary of architecture pdf https://fkrohn.com
