Xentrivalpeptides A–Q: Depsipeptide Diversification in Xenorhabdus
摘要:
Seventeen depsipeptides, xentrivalpeptides A-Q(1-17), have been identified from an entomopathogenic Xenorhabdus sp. Whereas the structure of xentrivalpeptide A (1) was determined after its isolation by NMR spectroscopy and the advanced Marfey's method, the structures of all other derivatives were determined using a combination of stable isotope labeling and detailed MS analysis.
