This compound is primarily utilized in the field of medicinal chemistry, particularly in the development of antiviral and anticancer agents. Its structure allows it to act as a nucleotide analog, which can inhibit the replication of viral DNA or RNA by incorporating itself into the nucleic acid chain, thereby terminating its extension. This mechanism is especially effective against viruses such as herpes simplex and cytomegalovirus. Additionally, its phosphonic acid group enhances its binding affinity to target enzymes, making it a potent inhibitor of viral polymerases. In cancer research, it is explored for its potential to interfere with the proliferation of cancer cells by disrupting nucleotide metabolism. Its unique properties make it a valuable candidate for further drug development and therapeutic applications.
