BIOLOGICALLY ACTIVE AMPHIPHILIC PEPTIDE COMPOSITIONS AND USES THEREFOR

摘要

Biologically active amphiphilic peptides including one of the following basic structures: I) R1-R2-R2-R1-R2-R2-R1-R1-R2-R1-R1; II) R2-R1-R2-R2-R1-R1-R2-R2-R1-R2-R2; III) R1-R2-R2-R1-R1-R2-R2-R1-R2-R2-R1-R1-R2-R3; IV) R1-R2-R1-R1-R2-R2-R1-R1-R2-R2-R4; V) R1-R1-R2-R2-R1-R2-R2-R1-R1-R2-R2-R3; or VI) R1-R1-R3-R2-R1-R1-R1-R1-R1-R1-R2-R1-R1-R2-R2-R1-R1-R2-R2-R1. R1 is a hydrophobic amino acid and R2 is a basic hydrophilic or neutral hydrophilic amino acid, R3 is a neutral hydrophilic amino acid, and R4 is a neutral hydrophilic amino acid or proline. There is also provided a biologically active amphiphilic peptide having a structural formula selected from the group consisting of: (a) R1-R2-R2-R1-R2-R2-R1; (b) R1-R1-R2-R2-R1-R2-R2-R1; (c) R2-R1-R1-R2-R2-R1-R2-R2-R1; (d) R2-R2-R1-R1-R2-R2-R1-R2-R2-R1; and (e) R1-R2-R2-R1-R1-R2-R2-R1-R2-R2-R1, wherein R1 and R2 are hereinabove described. Such peptides may be employed as pharmaceuticals.
