A purified isolate of an actinomycete identified as ATCC 39364 is capable of producing the anti-microbial/antitumor compound 2-amino-1,9-dihydro-6H-purin-6-one-7-oxide.
2-Amino-1,9-dihydro-6H-purin-6-one-7-oxide is produced by cultivating isolate ATCC 39364 under aerobic conditions in a culture medium containing assimilable sources of carbon and nitrogen until a substantial amount of the compound is produced and thereafter isolating the compound.
The antibiotic/antitumor compound 2-amino-1,9-dihydro-6H-purin-6-one-7-oxide and pharmaceutical compositions comprising this compound or one of its pharmaceutically acceptable salts together with a pharmaceutically acceptable carrier are also disclosed.
