Patent ID: 8445632

Claim:
A poly-N-substituted glycine antibiotic compound of a formula wherein A is a terminal N-alkyl substituted glycine residue, where said alkyl substituent is selected from about C 4 to about C 20 linear, branched and cyclic alkyl moieties; n is an integer selected from 1-3; B is selected from NH 2 , one and two N-substituted glycine residues, said N-substituents independently selected from natural α-amino acid side chain moieties, isomers and carbon homologs thereof; X, Y and Z are independently selected from N-substituted glycine residues, said N-substituents independently selected from natural α-amino acid side chain moieties, isomers and carbon homologs thereof, and proline residues, at least one of said X, Y and Z residues is N Lys and at least one said N-substituent is chiral.
