Abstract
Two new hydroxycitric acid lactone derivatives named cinatrins D (1) and E (2), and a new γ-lactam, virgaricin B (3), along with a known similar compound, virgaricin (4), were isolated from a fermentation broth of the fungus Virgaria boninensis FKI-4958. The absolute stereo structures of the new compounds were established by a combination of spectroscopic methods and chemical modifications. All three newly discovered compounds possessed weak antibacterial activity.Entities:
