摘要:
Ein aus gesunden weißen Blutkörperchen beziehungsweise Granulozyten isolierbares, das Wachstum beziehungsweise die Vermehrung von normalen und leukämischen myeloiden Zellen selektiv hemmendes Oligopeptid, welches die summenmäßige Aminosäurezusammensetzung worin
Tau für einen Rest von Taurin steht, Asx einen Rest von L-Asparagin und/oder L-Asparaginsäure bedeutet, Ser einen Rest von L-Serin darstellt, Thr für einen Rest von L-Threonin steht, Glx einen Rest von L-Glutamin und/oder L-Glutaminsäure bedeutet, Gly einen Rest von Glykokoll darstellt und Ala für einen Rest von L-Alanin steht, aufweist und bei einem pH-Wert von 6,5 eine negative Ladung und eine auf Asparaginsäure bezogene relative elektrophoretische Beweglichkeit von -0,55 bis -0,65 beziehungsweise bei einem pH-Wert von 1,9 keine Ladung und eine auf ε-(Dinitrophenyl)-lysin bezogene relative Beweglichkeit von etwa 0,26 zeigt und auf Chlortolidin positiv reagiert, ein Verfahren zur Herstellung dieses Oligopeptides und es enthaltende Arzneimittel, die auf dem Gebiet der Therapie zur Hemmung der Wucherung von humanen normalen beziehungsweise leukämischen Knochenmark-und Blutzellen verwendet werden können.
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.
摘要:
The invention relates to novel peptides comprising at least the amino acids Arg, Lys and Asp and optionally Val in that order wherein either (a) at least one of these is in the D-configuration, or (b) wherein Arg is bonded to the ε-amino group of Lys or, (c) an Arg amino acid is bonded to the α- and ε-amino groups of Lys or (d) the Val is bonded to the β-carboxy group of the Asp, or any combination of the above options (a) to (d), and acid addition salts thereof and their preparations. The novel peptides are useful in the therapy of diseases where the decrease in the activity of the immune system is desirable. I

摘要:
The present invention relates to novel pentapeptide of formula
pAad-Glu-Asp-Ser-Gly-OH,
wherein pAad represents the acyl group of pyro-alpha-aminoadipic acid, and salts thereof having specific inhibiting effect on epidermal cell proliferation, and pharmaceutical compositions comprising the same. The invention also relates to a process for the preparation of both the pentapeptide and the pharmaceutical composition.
摘要:
The invention relates to novel peptides of by formulae (1) to (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.
