Derbesiamides A–E: Cyclic Depsipeptides from Pedobesia Green Algae

Five cyclic depsipeptides, derbesiamides A–E, were isolated from the green alga Pedobesia sp. The planar structures were established by NMR and HRESI-TOFMS analyses, with absolute configurations determined via Marfey’s analysis and LC–MS/MS. This dataset, authored by Towa Tsukamoto and last updated in May 2026, expands the known chemical diversity of the Derbesiaceae family.

Use Cases

• Identify novel cyclic depsipeptide scaffolds based on the reported planar structures.
• Compare spectroscopic data (NMR, HRESI-TOFMS) for structure elucidation of similar marine metabolites.
• Apply Marfey’s analysis and LC–MS/MS methods for determining amino acid configurations in peptides.
• Explore the chemical diversity of the understudied Derbesiaceae family of green algae.

Strengths

• Contains data on five distinct cyclic depsipeptides (derbesiamides A–E).
• Structural elucidation employed multiple analytical techniques (NMR, HRESI-TOFMS, Marfey’s analysis, LC–MS/MS).
• Absolute configurations for constituent amino acids were determined.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 65.7 MB file size suggests a small dataset, potentially limiting statistical analysis scope.
