Abstract: © 2018 The Author(s) under exclusive licence to the Japan Antibiotics Research Association. We identified a new cyclic lipodepsipeptide, cystargamide B (1), from the mycelial extract of a Kaempferia galanga rhizome-derived actinomycete strain, Streptomyces sp. PB013. The planar structure was elucidated based on high resolution fast-atom bombardment mass spectrometry (HRFABMS) spectroscopy and one-dimensional (1D) and two-dimensional (2D) nuclear magnetic resonance (NMR) spectroscopic data. The absolute configurations of the constituent amino acids were determined using advanced Marfey's method. Cystargamide B (1) includes rare structural units: a 5-hydroxytryptophan residue and a 2,3-epoxy fatty acid side chain. Notably, cystargamide B (1) inhibited the protease activity of the NS2B/NS3 complex from dengue virus.
