ABSTRACT:
Synthetic immunomodulatory molecules having a .gamma.-L-glutamyl-, a .gamma.-D-glutamyl, a .beta.-L-aspartyl, or a .beta.-D-aspartyl moiety at the amino terminus are provided as illustrated by Formula A. In Formula A, "n" is 1 or 2, R is hydrogen, acyl or alkyl, and X is an aromatic or heterocyclic amino acid or its derivative. A particularly preferred embodiment is .gamma.-D-glutamyl-L-tryptophan, which has immunomodulatory activity.
