An unusual acyclic nor-triterpene derivative from Lacrymaria lacrymabunda mushroom active against methicillin-resistant Staphylococcus aureus (MRSA)
Year: 2026
Type: article
Abstract: An unusual linear nor-triterpene derivative named lacrymaric acid ( 1 ) was isolated from Lacrymaria lacrymabunda caps. This compound was revealed in TLC-bioautography as antibacterial against various Staphylococcus aureus strains, including methicillin-resistant clinical isolates (MRSA). The structure of 1 was unambiguously elucidated by spectroscopic analyses (HR-ESI-MS, 1D and 2D NMR) as an acyclic carboxylated nor-triterpene putatively derived from squalene.
