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 dedvative. A particularly preferred embodiment is .gamma.D-glutamyl-L-tryptophan, which has immunomodulatory activity.
L'invention concerne des molécules synthétiques immunomodulatrices comportant une fraction gamma -L-glutamyle, gamma -D-glutamyle, beta -L-aspartyle ou beta -D-aspartyle à l'extrémité N-terminale, représentées par la formule (A). Dans la formule (A), "n" est égal à 1 ou 2, R est hydrogène, acyle ou alkyle, et X est un acide aminé aromatique ou hétérocyclique ou un dérivé de celui-ci. Un mode de réalisation particulièrement préféré concerne la gamma -D-glutamyl-L-tryptophane, qui possède une activité immunomodulatrice.
