摘要:
The present invention concerns therapeutic agents that modulate the activity of PTH and PTHrP. In accordance with the present invention, modulators of PTH and PTHrP comprise: (a) a PTH/PTHrP modulating domain; and (b) a vehicle, such as a polymer (e.g., PEG or dextran) or an Fc domain, which is preferred; wherein the vehicle is covalently attached to the C-terminus of the PTH/PTHrP modulating domain or through a sidechain at any residue from residue 14 through the C-terminal residue. The vehicle and the PTH/PTHrP modulating domain may be linked through the N- or C-terminus of the PTH/PTHrP modulating domain, as described further below. The preferred vehicle is PEG. Preferred PTH/PTHrP modulating domains comprise the PTH and PTHrP-derived amino acid sequences described hereinafter. Other PTH/PTHrP modulating domains can be generated by phage display, RNA-peptide screening and the other techniques mentioned herein. Such peptides typically will be modulators of both PTH activity and PTHrP activity, although such techniques can be used to generate peptide sequences that serve as selective modulators (e.g., agonists of PTH activity but not PTHrP activity).

The present invention relates generally to the chemical modification of biologically active agents. More, specifically, the invention relates to a novel approach to engineer, through mutagenesis and site-directed chemical conjugation, specific, well-defined dualPEGylated-protein bioconjugates, consisting of two polyethylene glycol (PEG) macromolecules chemically conjugated to the protein at two specifically defined amino acid residues. The described dualPEGylated-protein bioconjugates show substantially improved bioefficacy and biocompatibility.
