  Chemical Synthesis and Biological Activity of Analogues of the Lantibiotic Epilancin 15X

  摘要：

  Lantibiotics are a large family of antibacterial peptide natural products containing multiple post-translational modifications, including the thioether structures lanthionine and methyllanthionine. Efforts to probe structure activity relationships and engineer improved pharmacological properties have driven the development of new methods to produce non-natural analogues of these compounds. In this study, solid-supported chemical synthesis was used to produce analogues of the potent lantibiotic epilancin 15X, in order to assess the importance of several N-terminal post-translational modifications for biological activity. Surprisingly, substitution of these moieties, including the unusual N-terminal D-lactyl moiety, resulted in relatively small changes in the antimicrobial activity and pore-forming ability of the peptides.

  Cytolysin, a two-component lanthipeptide comprising cytolysin S (CylL(s)") and cytolysin L (CyILL"), is the only family member to exhibit lytic activity against mammalian cells in addition to synergistic antimicrobial activity. A subset of the thioether cross-links of CylLs" and CylL(L)," have LL stereochemistry instead of the canonical DL stereochemistry in all previously characterized lanthipeptides. The synthesis of a CylLs" variant with DL stereochemistry is reported. Its antimicrobial activity was found to be decreased, but not its lytic activity against red blood cells. Hence, the unusual LL stereochemistry is not responsible for the lytic activity.
