Use in chemotherapy

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]
