Claim:
A compound and pharmaceutically acceptable salts thereof, according to structural formula (II): R 1 is OH or NH 2 ; L is selected from at least one amino acid, at least one substituted amino acid, and —O-PhC(═O)—; R 2 is selected from —C(═O)R 5 , —C(═O)OR 5 , —C(═O)NHR 4 , —C(═O)NR 4 R 4 , —C(═S)NHR 4 , —C(═S)NR 4 R 4 , —C(═NR 4 )NHR 4 , and —C(═NR 4 )NR 4 R 4 ; R 3 is at least one amino acid selected from Gly, β-alanine, GABA, 5-aminopentanoic acid, 6-aminohexanoic acid, Lys, gDab, Sar, Orn, Dap, hLys, or any combination thereof; R 4 is independently selected from (C 7 -C 10 ) alkyl, (C 17 -C 26 ) arylalkyl and 17 to 26 membered heteroarylalkyl, a branched or straight-chained, saturated or singly or multiply unsaturated aliphatic or hydroxy aliphatic moiety having a chain length of from 7 to 25 carbon atoms, a primary or secondary amine, at least one amino acid, and at least one substituted amino acid; and R 5 is independently selected from hydrogen, (C 1 -C 10 ) alkyl, (C 5 -C 10 ) aryl, 5 to 10 membered heteroaryl, (C 6 -C 26 ) arylalkyl and 6 to 26 membered heteroarylalkyl, a branched or straight chained, saturated or singly or multiply unsaturated aliphatic or hydroxy aliphatic moiety having a chain length of from 5 to 25 carbon atoms, a primary or secondary amine, at least one amino acid, at least one substituted amino acid, and any combination thereof.
