    摘要: The present invention provides compounds that are surrogates of post-translationally modified proteins and uses thereof. Numerous diseases are associated with post-translationally modified proteins that are difficult to obtain in homogenous form and in quantities needed for immunization and use as convenient standards, calibrators, and/or reference compounds that facilitate the detection and analysis of endogenous post-translationally modified proteins. The surrogate compounds of the invention typically comprise antigenic epitopes (one of which carries a post-translational modification) that are tethered by a flexible and hydrophilic linker. The resulting compound behaves like a surrogate of the post-translationally modified protein because it preserves the character of the included antigens and allows recognition by specific antibodies targeting the individual antigens. The surrogate compounds may be prepared by covalently joining two or more polypeptide epitopes using one or more linkers, wherein at least one of the epitopes comprises a post-translational modification. In one aspect, the surrogate compounds of the invention comprise a C-terminal epitope and a glycated epitope of human CD59. The inventive methods allow quantification of the levels of glycated CD59 in the serum in human subjects, particularly those with diabetes or pre-diabetes. This technological platform of post-translationally modified protein surrogates can be applied to other diseases associated with post-translationally modified proteins (e.g., autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, and systemic lupus erythematosus). In another aspect, the invention provides antibodies that bind specifically to the compounds of the invention and methods for producing such antibodies.

    摘要: The present invention relates to the use of peptide hormone analogues as inhibitors of their respective naturally occurring peptide hormone. The structure of the peptide hormone analogues is exemplified by parathyroid hormone (PTH), wherein Lys.sup.13 is substituted to increase the biological activity of the PTH analogues. Thus, there are disclosed peptides having the formulae:PTH(7-34)NH.sub.2 ;[Tyr.sup.34 ]PTH(7-34)NH.sub.2 ;[D-Trp.sup.12, Tyr.sup.34 ]PTH(7-34)NH.sub.2 ;[Nle.sup.8,18, D-Trp.sup.12, Tyr.sup.34 ]PTH(7-34)NH.sub.2 ;[Nle.sup.8,18, Tyr.sup.34 ]PTH(7-34)NH.sub.2 ;desamino[Nle.sup.8,18, D-Trp.sup.12, Tyr.sup.34 ]PTH(7-34)NH.sub.2 ; and,desamino[Nle.sup.8,18, D-Trp.sup.12, Tyr.sup.34 ]PTH(8-34)NH.sub.2wherein Lys.sup.13 is modified in the epsilon-amino acid group by N,N-diisobutyl or 3-phenylpropanoyl.
