This compound is primarily used in medical research, particularly in the development of antiviral and anticancer therapies. It functions as a nucleoside analog, which means it can mimic the building blocks of DNA or RNA, making it effective in disrupting the replication process of viruses and cancer cells. In antiviral applications, it is studied for its potential to inhibit the growth of certain viruses by incorporating itself into viral DNA, causing premature termination of the viral genetic material. In cancer research, it is explored for its ability to interfere with the DNA synthesis of rapidly dividing cancer cells, thereby slowing or stopping tumor growth. Its unique structure, particularly the fluorine atom, enhances its stability and effectiveness in biological systems. Researchers are also investigating its use in diagnostic imaging, where it can be labeled with radioactive isotopes to track cellular processes in real time.
