ANTIBACTERIAL AND ANTIVIRAL PEPTIDES FROM ACTINOMADURA NAMIBIENSIS

摘要

The invention refers to of a compound of the formula (I) wherein R3 and R4 are independently H or OH, and wherein m and n are independently of one another 0, 1 or 2, obtainable from Actinomadura namibiensis (DSM 6313), its use for the treatment of bacterial infections, viral infections and/or pain, and pharmaceutical composition comprising it. The compounds of formula (I) have been defined as labyrinthopeptins and consist of a highly bridged peptidic structure of 18 amino acids containing lanthionine-like residues and alpha disubstituted amino acid analogues. The amino acid sequence is XDWXLWEXCXTGXLFAXC, wherein the two Cys residues form a disulfide bridge and each X independently represents one of the non-natural amino acids involved in the bridging linkages.
