Patent ID: 7754691

Claim:
A linear peptide of the formula: wherein: R 1 is H, NH 2 , R 2 is in each instance independently an amino acid side chain moiety; R 3 is 4-imidazolyl, 3-indolyl, 2-pyrrolidine, phenyl, or 1- or 2-naphthyl, optionally with one or two ring substituents, and when one or both ring substitutents are present, are the same or different and independently hydroxyl, halogen, alkyl, or aryl groups attached directly or through an ether linkage; R 4 is —NH 2 , —NH—(CH 2 ) y —NH 2 , or —NH—(C═NH)—NH 2 ; R 5 is 1- or 2-naphthyl, optionally with one or two ring substituents, and when one or both ring substitutents are present, are the same or different and independently hydroxyl, halogen, alkyl, or aryl groups attached directly or through an ether linkage; R 6 is in each instance independently H or an amino acid side chain moiety; R 7 is H, NH 2 , a lower aliphatic C 1 to C 4 linear or branched alkyl chain, a C 1 to C 4 aralkyl, or a C 1 to C 4 omega amino derivative; R 8 is H, a lower aliphatic C 1 to C 4 linear or branched alkyl chain, a C 1 to C 4 aralkyl, a C 1 to C 4 linear alkyl chain with an N-terminus carboxyl group, or a C 1 to C 4 omega amino derivative; R 9 is a linear or branched C 1 to C 17 alkyl, aryl, heteroaryl, alkene, alkenyl, or aralkyl chain; n is from 0 to 3; m is from 0 to 7; x is 2 to 5; and y is 1 to 3.
