    摘要: Phosphonate-nucleotide ester compounds of the formula (I) have excellent antiviral activity and antineoplastic activity. Further, they can be orally administered. ##STR1## wherein ring A represents ##STR2## wherein R.sup.1 and R.sup.2 independently represent hydrogen, halogen, hydroxyl, mercapto, C.sub.6 -C.sub.10 arylthio or amino; R.sup.3 represents C.sub.1 -C.sub.4 alkyl or ethyl having one or more substituents selected from the group consisting of fluorine, C.sub.1 -C.sub.4 alkoxy, phenoxy, C.sub.7 -C.sub.10 phenylalkoxy and C.sub.2 -C.sub.5 acyloxy; R.sup.4 represents ethyl having one or more substituents selected from the group consisting of fluorine, C.sub.1 -C.sub.4 alkoxy, phenoxy, C.sub.7 -C.sub.10 phenylalkoxy and C.sub.2 -C.sub.5 acyloxy; X, Y and Z independently represent methyne or nitrogen atom; or a pharmaceutically acceptable salt thereof.
