Derbesiamides A–E: Cyclic Depsipeptides from Pedobesia Green Algae

Five novel cyclic depsipeptides, named derbesiamides A–E, were isolated from the green alga Pedobesia sp. The planar structures were established using NMR and HRESI-TOFMS analyses, with absolute configurations determined via Marfey's analysis and synthetic comparisons. This dataset, shared by Towa Tsukamoto on figshare, expands the known chemical diversity of the Derbesiaceae family.

Use Cases

• Identifying novel bioactive compounds based on cyclic depsipeptide structures.
• Studying chemical diversity within the Derbesiaceae family of green algae.
• Comparing spectroscopic data for structure elucidation based on NMR and HRESI-TOFMS analyses.
• Investigating the biosynthetic pathways of marine-derived secondary metabolites.

Strengths

• Contains data on five distinct novel compounds (derbesiamides A–E).
• Structural elucidation employed multiple analytical techniques including NMR and HRESI-TOFMS.
• Absolute configurations were determined using Marfey's analysis and synthetic diastereomeric comparisons.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset size is 41.7 MB, indicating a relatively small scale.
