    摘要: Immunostimulating 7,8-disubstituted guanine derivatives that also contain a morpholinyl group as a position-9 substituent are disclosed whose structures are represented by formula I ##STR1## wherein X is O or S; R.sup.1 is a hydrocarbyl or substituted hydrocarbyl group having a length of about one to about seven carbon atoms; R.sup.2 is a hydrogen or C.sub.1 -C.sub.8 acyl; R.sup.3 is hydrogen, a C.sub.1 -C.sub.5 aliphatic hydrocarbyl, aralkyl or substituted aralkyl group; and the pharmaceutically acceptable base addition salts thereof. Also disclosed are compositions containing an immunostimulating substituted guanine derivative and processes for using the same.
