Patent ID: 7550430

Claim:
A peptide represented by Formula I: (B)-(U)-(Z-B-B-Z-Z-B-Z) n -(U) Formula (I) wherein B, U and Z represent natural or unnatural amino acids and wherein: (a) the amino acids of each (ZBBZZBZ) unit are determined independently; (b) in each (ZBBZBZ) unit, Z is independently selected from Gly or a hydrophobic amino acid selected from the group consisting of Leu, Ile, Trp, Phe, Val, Met, and Ala; and (i) wherein in at least one (ZBBZZBZ) unit, one Z is Gly, (ii) when Z is Gly, the Gly residues representing Z must be minimally 7 amino acid residues apart; and (iii) no more than six sequential hydrophobic Z residues may occur in the peptide; (c) B is a cationic amino acid independently selected from the group consisting of Lys, Arg, His, Orn, Har, and Dbu; and (d) U is Gly, Cys or Cys(R), wherein R is a protecting group on the Cys thiol; (e) n=2-8; and (f) the N-terminal B residue, and the N-terminal or C-terminal U residue, are optionally part of the peptide.
