The search for new therapeutic agents that are effective against cancer has been difficult and expensive. The activity of anticancer candidate agents against human cancer-derived cell lines in immunocompromised mice is an important tool in this search. Because ATP is a naturally occurring small molecule, its radiolabeled form poses many advantages as a potential anticancer therapeutic agent. We previously found that a single, low-dose intravenous injection of [32P] ATP inhibited the growth of xenografted tumors in nude mice for up to several weeks. The current study describes the biodistribution and the results and advantages of multi-dose administration of this potential drug. Future studies should investigate the mechanism involved in the possible use of [32P]ATP as a cytotoxic agent that homes naturally to the tumor microenvironment.
