Abstract: Peptides having four to six amino acid residues are disclosed that possess biological activity. These peptides constitute short fragments of the peptide HB-107 (MPKEKVFLKIEKMGRNIRN), which itself is a fragment of the antimicrobial protein cecropin B, and exhibit cell stimulatory and migratory properties. The inventive peptides comprise four to six contiguous amino acid residues located between position 11 and 16 of HB107 (MPKEKVFLKIEKMGRNIRN), namely EKMGRN. The disclosed peptides comprise a useful agent for the medical treatment of injury to the skin, such as from diabetic ulcers. The peptides also are effective in preventing and reversing skin surface damage resulting from various environmental insults. Importantly, the therapeutic effects of the peptides manifest at concentrations equal to or greater than those of peptide HB-107, and thus represent a less expensive, more versatile means for developing effective therapies. Methods for the production and use of these peptides are also disclosed.

Abstract: Advanced glycation end products (AGEs) represent a non-enzymatic post-translational protein modification. AGEs are very stable and the accumulation over time can be used as markers of carbonyl stress which are responsible for the malfunction of bioactive macromolecules in the body. Disclosed herein are a series of short peptides for blocking activity of advanced glycation end products (AGEs), the peptide being derived from a V-region of an sRAGE protein, wherein the V-region is given by SEQ ID NO:61. These peptides effectively inhibit the progress of a Maillard reaction, blocking the AGEs and inhibiting dicarbonyl induced cell apoptosis and death. The peptides can be used as, for example, an anti-glycation agent, a skin anti-aging agent, or an anti-diabetic complication agent.

Abstract: Peptides having four to fourteen residues are disclosed that possess biological activity. These peptides constitute short fragments of the peptide HB-107 (SEQ ID NO:1), which itself is a fragment of the antimicrobial protein cecropin B, and exhibit cell stimulatory, migratory and anti-inflammatory properties. As keratinocytes are especially sensitive to these effects, the disclosed peptides comprise a useful agent for the medical treatment of injury to the skin, such as from diabetic ulcers. The peptides also are effective in preventing and reversing skin surface damage resulting from various environmental insults. Importantly, the therapeutic effects of the peptides manifest at concentrations equal to or greater than those of peptide HB-107, and thus represent a less expensive, more versatile means for developing effective therapies.

Abstract: Tetrapeptides consisting of (I or V)-X1-K-X2, where X1 can be selected from E, Q or K, and X2 can be selected from M, F, I, W, or V, exhibit diverse bioactivities. They are multi-functional effector molecules to stimulate keratinocytes migration; neutralize the proinflammatory effect of bacterial cell wall components such as lipoteichoic acids of the Gram-positive S. aureus; and induce angiogenesis in cultured human umbilical vein endothelial cells. The downregulation of pro-inflammatory condition was also demonstrated using SOR-300-FT psoriasis skin model for representative peptide. The bioactivity was also supported by gene profiling study upon treatment of normal skin tissues using EPIDERM TM skin substitutes. The inventive peptides with diverse bioactivities are useful for treating various skin conditions including, but not limited to, acute or chronic wounds, striae distensae, aging skin, hair control, inflammatory skins such as psoriasis, atopic dermatitis and rosacea and for unwanted hair removal or for conditions such as removal of skin tags.
