摘要:
The peptide a-melanocyte stimulating hormone (a-MSH) is found in barrier organs such as the gut and skin. The anti-inflammatory properties of the peptide make it useful for treating inflammation in human and veterinary disorders. It has been found that this peptide, and other peptides derived from a-MSH, possess antimicrobial activity against Staphylococcus aureus and Candida albicans. These a-MSH peptides exhibited antimicrobial effects over a broad concentration range, including the physiological (picomolar)range. Of particular interest are those peptides that include the amino acid sequence KPV, or those including the sequence MEHFRWG. Peptides having the most potent antimicrobial activity were those bearing the C-terminal amino acid sequence of a-MSH. Anti-inflammatory agents based on a-MSH peptides, with enhanced antimicrobial activity, would minimize the risk of further infection that is generally associated with treatments using coticosteroids or other nonsteroidal anti-inflammatory drugs.

Peptides capable of modulating beta 1 integrin subunit dependent cell adhesion which includes a C-terminal aromatic amino acid residue and an amino acid residue having a lipophilic alkyl side chain as the penultimate C-terminal residue are provided. These "LipAr" C-terminated peptides are typically capable of modulating the beta 1 integrin subunit dependent adhesion of cells, such as Ramos cells.

摘要:
An antipyretic tripeptide, having the amino acid sequence lysine-proline-valine, and a method for utilizing the tripeptide to reduce fever and inflammation in mammals. The tripeptide can either be isolated from natural sources or chemically synthesized. A ''protected'' tripeptide having greater antipyretic potency and duration of action is also disclosed. The ''protected'' tripeptide contains an acyl group, such as an acetyl or a dibenzyl oxy carboxyl group, at its amino terminals and is amidated or esterified at its carboxyl terminals. Further, improved antipyretic potency and direction of action can be achieved through the co-administration of copper salts with the tripeptide.
