Claims
- 1. A method of modulating hemopoiesis in an animal comprising administering to the animal an effective amount of one or more of the peptides of formula I:
- X--Glu--Trp--Y (I)
- wherein X is H, Gly, Ala, Leu, Ile, Val, NVal, Pro, Tyr, Phe, Trp, D-Ala, D-Leu, D-Ile, D-Val, D-NVal, D-Pro, D-Tyr, D-Phe, D-Trp, His, Lys, Arg .gamma.-aminobutyric acid, or .xi.-aminocaproic acid; Y is Gly, Ala, Leu, Ile, Val, NVal, Pro, Tyr, Phe, Trp, D-Ala, D-Leu, D-Ile, D-Val, D-NVal, D-Pro, D-Tyr, D-Phe, D-Trp, Arg, .gamma.-aminobutyric acid, .xi.-aminocaproic acid, --OH, NH.sub.2, N.sub.2 H.sub.3, or a mono- or di-substituted amide (C.sub.1 -C.sub.3); with the proviso that when X is H, Y is not --OH and a pharmaceutically acceptable carrier.
- 2. The method of modulating hemopoiesis in an animal according to claim 1 wherein the one or more peptides are selected from the group consisting of: H-Ile-Glu-Trp-OH, His-Glu-Trp-OH, H-Glu-Trp-NH.sub.2, H-Glu-Trp-Arg, Lys-Glu-Trp-OH, Arg-Glu-Trp-OH, H-Glu-Trp-Tyr, Lys-Glu-Trp-Tyr, H-Glu-Trp-N.sub.2 H.sub.3, H-Glu-Trp-Gly, and Val-Glu-Trp-OH.
- 3. The method of modulating hemopoiesis in an animal according to claim 2 wherein the one or more peptides comprises H-Ile-Glu-Trp-OH.
- 4. The method of modulating hemopoieses in an animal according to claim 3 wherein the one or more peptides consists of H-Ile-Glu-Trp-OH.
- 5. The method according to claim 1 wherein an effective amount of the peptide is 0.001-0.1 mg/kg weight of the animal.
- 6. The method according to claim 1 wherein the modulation of hemopoiesis comprises stimulating hemopoieses in an animal.
- 7. The method of claim 6 wherein the one or more peptides comprises H-Ile-Glu-Trp-OH.
- 8. The method according to claim 1 wherein the modulation of hemopoiesis comprises the restoring of hemopoiesis in an animal with impaired hemopoiesis.
- 9. The method according to claim 7 wherein the one or more peptides comprises H-Ile-Glu-Trp-OH.
