    • The present invention relates to a method of carbamylating an erythropoietin such that the resulting carbamylated erythropoietin has less that about 10% free primary amines on the lysines and the N-terminal amino acids, is not digested when exposed to Lys-C proteolysis, exhibits no erythropoietic activity in a TF-1 or UT-7/EPOR cell viability assay at a concentration of 1 µg/ml, and demonstrates a static sciatic index of less than about .65 within a Sciatic Nerve Assay. Additionally, the invention is related to pharmaceutical compositions containing carbamylated erythropoietins of the invention and the use of the pharmaceutical compositions for the treatment of conditions and diseases of excitable tissues.

    • The present invention is directed to novel tissue protective peptides. The tissue protective peptides of the invention may bind to a tissue protective receptor complex. In particular, the present invention is drawn to tissue protective peptides derived from or sharing consensus sequences with portions of cytokine receptor ligands, including Erythropoietin (EPO), that are not involved in the binding of the ligand to the receptor complex, e.g., to the EPO receptor homodimer. Accordingly, the tissue protective peptides of the invention are derived from the amino acid sequences of regions of cytokine receptor ligands that are generally located on or within the region of the ligand protein that is opposite of the receptor complex, i.e., are generally derived from amino acid sequences of regions of the ligand protein that face away from the receptor complex while the ligand is bound to the receptor. The invention is further directed to the consensus sequences for use in engineering a synthetic tissue protective peptide. These tissue protective peptides also include fragments, chimeras, as well as peptides designed to mimic the spatial localization of key amino acid residues within the tissue protective receptor ligands, e.g., EPO. The invention further encompasses methods for treating or preventing a disease or disorder using tissue protective peptides of the current invention. The invention also encompasses methods for enhancing excitable tissue function using tissue protective peptides of the current invention.
    • 本发明涉及新型组织保护肽。 本发明的组织保护肽可以结合组织保护性受体复合物。 特别地,本发明涉及来自或共享具有部分细胞因子受体配体(包括促红细胞生成素(EPO))的组织保护肽,其不参与配体与受体复合物的结合,例如与 EPO受体同二聚体。 因此,本发明的组织保护肽衍生自通常位于与受体复合体相反的配体蛋白的区域上或内部的细胞因子受体配体的区域的氨基酸序列,即通常衍生自氨基 当配体与受体结合时,配体蛋白的表面远离受体复合物的酸序列。 本发明还涉及用于工程化合成组织保护肽的共有序列。 这些组织保护肽还包括片段,嵌合体以及旨在模拟组织保护性受体配体例如EPO内的关键氨基酸残基的空间定位的肽。 本发明还包括使用本发明的组织保护肽治疗或预防疾病或病症的方法。 本发明还包括使用本发明的组织保护肽增强可兴奋组织功能的方法。
