NOVEL OLIGOPEPTIDES EXHIBITING SELECTIVE INHIBITING EFFECT UPON THE PROLIFERATION OF HEMOPOIETIC CELLS, PHARMACEUTICAL COMPOSITION COMPRISING THE SAME AND PROCESS FOR THE PREPARATION OF THE NOVEL OLIGOPEPTIDES AND COMPOSITIONS

摘要

The present invention relates to peptides of formulae (1) Glp-Glu-Asp-Cys(Acm)-Lys-OH and (2) H-Glu-Asp-Cys(Acm)-Lys-OH wherein Acm represents an acetamidomethyl group, the acid addition salts thereof, pharmaceutical compositions comprising the same and processes for their preparation. The peptides selectively inhibit the proliferation of hemopoietic cells.
