Described are peptides and peptide mimetics that bind to and activate the thrombopoietin receptor. Such peptides and peptide mimetics are useful in methods for treating hematological disorders and particularly, thrombocytopenia resulting from chemotherapy, radiation therapy, or bone marrow transfusions as well as in diagnostic methods employing labeled peptides and peptide mimetics.

Peptides and compounds that bind to a receptor

Receptors are peptides and peptide mimetics that bind to and activate the thrombopoietin receptor. Such peptides and peptide mimetics are useful in methods for treating hematological disorders and particularly, thrombocytopenia resulting from chemotherapy, radiation therapy, or bone marrow transfusions as well as in diagnostic methods employing labeled peptides and peptide mimetics.

Peptides and compounds that bind to a thrombopoietin receptor

Peptides of 10 to 40 or more amino acid residues in length and having the sequence X3X4X5GPX6TWX7X8 (SEQ ID NO:252) where each amino acid is indicated by standard one letter abbreviation; X3 is C; X4 is R, H, L, or W; X.sub.5 is M, F, or I; X6 is independently selected from any one of the 20 genetically coded L-amino acids; X7 is D, E, I, L, or V; and X8 is C, which bind and activate the erythropoietin receptor (EPO-R) or otherwise act as an EPO agonist, and methods for their use.
