To address the issue of degradation by enzymatic reactions to proteins and peptides, polyethylene glycol (PEGylation) of the proteins and peptides has been established. PEGylated proteins and peptides have increased plasma half-lives and reduced immunogenicity. To further improve and extend the plasma half-life of desired protein or peptide therapeutics, a novel branched molecule of PEG possessing three PEGs with a single point of attachment is designed in this invention disclosure.

A method for protecting a peptide from peptidase activity in vivo, the peptide being composed of between 2 and 50 amino acids and having a C-terminus and an N-terminus and a C-terminus amino acid and an N-terminus amino acid is described. In the first step of the method, the peptide is modified by attaching a reactive group to the C-terminus amino acid, to the N-terminus amino acid, or to an amino acid located between the N-terminus and the C-terminus, such that the modified peptide is capable of forming a covalent bond in vivo with a reactive functionality on a blood component. In the next step, a covalent bond is formed between the reactive group and a reactive functionality on a blood component to form a peptide-blood component conjugate, thereby protecting said peptide from peptidase activity. The final step of the method involves the analyzing of the stability of the peptide-blood component conjugate to assess the protection of the peptide from peptidase activity.

Treatments are disclosed for inflammatory, autoimmune, or other disorders characterized by excessive activity of calprotectin, a protein that normally defends against microbial infections by sequestering available zinc, at a site of infection. Excessive calprotectin activity, which can cause zinc deficiencies in localized tissues, can create or aggravate various disorders. However, ingestion of systemic (oral) zinc supplements tends to activate offsetting mechanisms, and such supplements therefore usually are ineffective. Accordingly, targeted treatments are disclosed herein for suppressing and controlling excessive calprotectin activity, in local tissues. Such methods include targeted injections of zinc solutions, and plasmapheresis treatment. Screening tests also are described for identifying non-protein drugs that can either (i) bind specifically to the zinc-binding sites of calprotectin, or (ii) suppress the release of calprotectin by neutrophil cells.
