carbons 5 and 7 were isolated from the cultures of Streptomyces bulli GJA1, an endophyte of
Gardenia jasminoides, together with two known ones (3 and 4). The MS2-based molecular
networking system facilitated the isolation of compounds with target functionalities. The
stereochemistry of 1 was completely established by ROESY and ECD experiments.
Compound 3 showed antivirulence activities by inhibiting the peptide toxin (PSMs) …
