ABSTRACT:
Compounds of the formula ##STR1## where X is OH, NH.sub.2, SH, OR or SR (where R is alkyl of 1 to 4 carbon atoms or benzyl), R.sup.1 is H or alkyl of 1 to 8 carbon atoms, R.sup.2 is H or methyl, Y is the salt of an amine of the formula ##STR2## where R.sup.3 and R.sup.4 are lower alkyl, e.g., 1 to 4 carbon atoms and n is an integer of 2 to 4 with p-acetamidobenzoic acid and where z is a number from 0 to 10 are useful as immunomodulators, as antiviral agents and in specific cases have anti-leukemic activity. The compounds and compositions where z is 1 to 10 are novel per se. When R.sup.2 is H the presence of Y enhances the immunoregulatory activity and the antiviral activity. If X is the NH.sub.2 there is immunoinhibitory activity but no immunostimulatory (immunopotentiatory) activity.
