ROS are generated as byproducts of cellular metabolism and play a crucial role in redox signaling and cellular homeostasis. Nevertheless, excessive ROS levels can damage cellular components such as DNA, proteins, and lipids, resulting in DNA mutations and genome instability that contribute to the progression of cancer [13].  Recent research has shown that thiol-containing amino acids, such as glutathione (GSH), cysteine (Cys), and homocysteine (Hcy), play an essential role in regulating the redox balance in cancer cells. These amino acids serve as antioxidants by scavenging reactive oxygen species (ROS) and preventing oxidative damage. In addition, cancer cells have greater access to thiol-containing amino acids than normal cells, making them an attractive target for the development of anticancer therapies.  Additionally,
