title: Preparation of new 7-hydroxyguanine derivatives and their biological activities.
abstract: We prepared new 7-hydroxyguanine derivatives, 7-hydroxyguanosine 5'-monophosphate and N2-tetrahydropyranyl-7-hydroxyguanine, and compared biological activities of 7-hydroxyguanine derivatives including nucleosides acquired previously. 7-Hydroxyguanine and its nucleotide inhibited the focus formation of Rous sarcoma virus. Antitumor activities of these derivatives against mouse leukemia L1210 were not so different from one another. Anti-proliferative activities of the derivatives on various human cell lines were significantly different from one another.
