One of the most intriguing problems in cancer therapy is why drugs that affect ubiquitous enzyme systems have any predilection for tumor cells. Classical biochemical techniques involving the identification of target enzymes have only rarely demonstrated differences between the normal and the neoplastic cell. Although there has been considerable interest in cell-control mechanisms based on elegant work in bacterial genetics, biochemists and pharmacologists are only recently paying some attention to the cell cycle as a potential "control mechanism." The kinetic restrictions imposed on the rhythmic appearance and disappearance of enzymes amenable to chemotherapeutic attack may well result in a selective
