Background
- Swinholide A is a 44-carbon dimeric dilactone ring macrolide isolated from the marine sponge Theonella swinhoei. In vitro, it sequesters actin dimers with a binding stochiometry of 1:1, and it rapidly severs F-actin with high cooperativity. Swinholice A is potently cytotoxic by disruption of the actin cytoskeleton. It does not block progression of cells through the cell cycle, but does prevent cytokinesis.
