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.
提供具有γ-L-谷氨酰基,γ-D-谷氨酰基,β-L-天冬氨酰基或β-D-天冬氨酰基官能团的合成免疫调节分子,如公式A所示。在公式A中,“n”为1或2,R为氢,酰基或烷基,X为芳香族或杂环氨基酸或其衍生物。一个特别优选的实施例是γ-D-谷氨酰基-L-色氨酸,具有免疫调节活性。
