8-Azaguanine is a purine analog with the chemical formula C4H4N6O. It has been widely studied for its biological activity.[5] It shows antineoplastic activity and has been used in the treatment of acute leukemia.[2]

Use in chemotherapy[edit]

The compound closely resembles guanine and appears to be competitive with it in the metabolism of living organisms.[6] It has been shown to cause retardation of some malignant neoplasms when administered to tumors in animals.[6] 8-Azaguanine was the first purine analogue discovered to inhibit experimental tumors in mice.[7]
