Spiro-Linked Polyketides from Westerdykella dispersa as iNOS Inhibitors

Seven chemical entities isolated from the fungal strain Westerdykella dispersa Ca4–13, collected from edible oysters in Taiwan. Their structures were elucidated by spectroscopic analysis, and four compounds exhibited anti-inflammatory activity in LPS-induced BV-2 microglial cells. The dataset was authored by Shu-Jung Huang and last updated on 2026-05-28.

Use Cases

• Identify potential drug leads based on anti-inflammatory activity against nitric oxide production.
• Perform molecular docking analysis based on the provided murine iNOS (PDB ID: 1QW4) target.
• Study structure-activity relationships based on the novel C14 and rare C28 polyketide structures.
• Screen for iNOS protein expression inhibitors based on the activity of compounds 2 and 3.

Strengths

• Includes IC50 values for anti-inflammatory activity ranging from 9.9 to 11.3 μM.
• Contains data on seven elucidated chemical structures, including novel and rare polyketides.
• Provides molecular docking analysis results for structural insight into inhibition.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the single fungal strain source in Taiwan.
