Anti-inflammatory peptide analogs and treatment to inhibit vascular leakage in injured tissues

摘要

Small, anti-inflammatory compounds that are peptide analogs are described useful to inhibit inflammation of a mammal's skin, mucous membranes, or lacerations of the musculature or injury to the brain or leakage of fluids into the air spaces of the lungs. Peptide analogs of the invention have the primary sequence TN-A1-A2-A3-A4-A5-A6-TC where one of the moieties is in the D-configuration. A1 and A2 are each a basic polar amino acids while each of A3, A4, and A6 is a hydrophobic amino acid. A5 can be a variety of structures and appears to function to optimize the spatial relationship between the hydrophobic and the basic residues. TN is selected or modified to convey resistance against enzymatic degradation. TC is an amino group or an amidated amino acid, preferably hydrophobic.
