NOVEL PEPTIDES INHIBITING THE MATURATION OF T-LYMPHOCYTES AND THE ACTIVITY OF MACROPHAGES, PHARMACEUTICAL COMPOSITIONS CONTAINING THEM AND PROCESS FOR PREPARING SAME

摘要

The invention relates to novel peptides of by formulae (1) to (20): Arg-Lys(Chc)-Asp-Val (1) Arg-Lys(Chc)-Asp (2) Arg-Sar-Asp-Val (3) Arg-Sar-Asp (4) Orn-Lys-Asp-Val (5) Orn-Lys-Asp (6) Arg-Lys-Aad-Val (7) Arg-Lys-Aad (8) [Arg-Lys-Asp-NH-CH2-]2 (9) [Arg-Lys-Asp-Val-NH-CH2-]2 (11) [Arg-Lys-Asp- @ys-NH2]2 (12) Lys-Ser-Lys-Leu (13) Ser-Lys-Leu (14) Ser-Ser-Ser-Thr (15) Lys-Glu-Thr (16) Lys-Thr-Glu-Thr (17) Pro-Lys-Leu-Thr (18) Lys-Lys-Thr-Glu (19) Lys-His-Leu-NH2 (20) and their preparation. The novel peptides are useful for therapy, where a general suppressing action on the function of the immune system is desired.
