Purines and purine nucleoside analogues as antitumour agents

1990
Purines, purine nucleosides and their analogues have been extremely useful as anticancer agents. Robins1, in 1964, reviewed the antitumour activity of purines and purine nucleosides from a structure-activity standpoint. Subsequently, several reviews on this subject have been published2–7.
