概要 Myticalin A6 (3-23)-OH is an antimicrobial peptide with a 7-repeat sequence: (X-Pro-Arg)7, where X = Trp, Tyr, Leu, or Ile. We synthesized N-terminal fatty acylated or tryptophan-substituted myticalin A6 (3-23)-OH derivatives, aiming to increase their antibacterial activity and reduce their cytotoxicity. Derivatives in which Ile9 or Leu12 was substituted with Trp showed comparable antibacterial activity and cytotoxicity. IC50 values indicated 3-amino-4-(2-naphthyl)butyl- myticalin A6 (3-23)-OH was slightly less cytotoxic than myticalin A6 (3-23)-OH.
