Therapeutic agents useful in the invention include wound healing agents, antibiotics, anti-inflammatories, anti-oxidants, anti-proliferatives, immunosupressants, anti-infective and anti-cancer agents.
摘要:
Modified anti-angiogenic peptides are disclosed. The modified peptides are capable of forming a peptidase stabilized anti-angiogenic peptide. The modified anti-angiogenic peptides, particularly modified kringle 5 peptides are capable of forming a conjugate with a blood protein. Conjugates are prepared from anti-angiogenic peptides, particularly kringle 5 peptides, by combining the peptide with a reactive functional group with a blood protein. The conjugates may be formed in vivo or ex vivo. The conjugates are administered to patients to provide an anti-angiogenic effect.

This invention relates to glucagon-like peptide 2 (GLP-2) derivatives. In particular, this invention relates to GLP-2 peptide derivatives having an extended in vivo half-life, for the treatment or prevention of gastrointestinal disorders or diseases such as inflammatory bowel disease and other gastrointestinal functions, from any segment of the gastrointestinal tract, from the oesophagus to the anus.

摘要:
Peptides exhibiting anti-viral and anti-fusogenic activity are modified to provide greater stability and improved half-life in vivo. The selected peptides include fusion inhibitors DP178 and DP107 and related peptides and analogs thereof. The modified peptides are capable of forming covalent bonds with one or more blood components, preferably a mobile blood component.
摘要:
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.
摘要:
Conjugated are prepared from antinociceptive a agents, particularly opioids or opioid analoges, more particularly deltorphins, enkephalins or analogs thereof, by combining said antinociceptive agent with a material providing a functionally reactive group capable of reacting with a blood component (preferably cell or protein). Said conjugates permit extension of the therapeutic life of the antinociceptive agent. They may be administered to patients to alleviate pain, produce analgesic effects, or assist in cases of narcotics withdrawal, and may also be used as probes for receptor activity. The administration to the patient ma be made either in vivo or ex vivo and may be performed by either introducing the derivative including the reactive functional group into the patient's vascular system or preparing such a conjugate externally (or in vitro) and introducing that conjugate to the patient's vascular system.
摘要:
The present invention relates to a method for separating albumin conjugate from unconjugated albumin in a solution comprising albumin conjugate and unconjugated albumin by loading the solution onto a hydrophobic support equilibrated in aqueous buffer having a high salt content; applying to the support a gradient of decreasing salt concentration; and collecting the eluted albumin conjugate.
