Abstract: Novel synthetic Arg-Gly-Asp containing peptides which have high affinity and specificity for their receptors by virtue of restrictions on their stereochemical conformation. Such restrictions can be provided by cyclization, by inclusion into a constraining conformational structure such as a helix, by providing an additional chemical structure such as an amide or an enantiomer of a naturally occurring amino acid, or by other methods. In particular, there are provided cyclic peptides having increased affinity and selectivity for the certain receptors over that of linear, Arg-Gly-Asp-containing synthetic peptides.

Abstract: Disclosed are methods for inhibiting and modulating the actions of CXC intercrine molecules. The antileukinate peptides described inhibit IL-8, GRO and MIP2.beta. binding to neutrophils and neutrophil activation. The peptides are particularly advantageous as they inhibit IL-8-induced enzyme release at a 25 fold lower concentration than is required to inhibit chemotaxis, which makes them ideal for treating various inflammatory diseases and disorders including, amongst others, Adult Respiratory Distress Syndrome (ARDS), cystic fibrosis and chronic bronchitis.
