Swinholide A, Theonella swinhoei (CAS 95927-67-6)

Swinholide A, a natural product isolated from the marine sponge Theonella swinhoei, is a potent cytotoxic macrolide known for its unique mechanism of disrupting the actin cytoskeleton. Swinholide A exerts its effects by binding to actin filaments, promoting their severing and leading to the depolymerization of the actin network. This disruption of the cytoskeleton affects various cellular processes, including cell shape, motility, and division, making it a valuable tool in cell biology research. In research, Swinholide A is used to study the dynamics and regulation of the actin cytoskeleton. Its ability to sever actin filaments has been instrumental in elucidating the roles of actin in maintaining cellular architecture and in processes such as intracellular transport and signal transduction. Researchers employ Swinholide A to investigate the molecular mechanisms underlying actin filament turnover and to identify the pathways and proteins involved in cytoskeletal regulation. Furthermore, Swinholide A serves as a model compound for studying the interactions between natural products and the cytoskeleton, providing insights into how marine-derived macrolides can influence cellular functions. Its use in high-content screening assays helps identify potential modulators of actin dynamics, contributing to the broader understanding of cytoskeletal biology. The research applications of Swinholide A extend to exploring its impact on cellular processes.
