生物活性

Swinholide A is the actin-binding marine polyketide and dimerizes actin with the Kd of ~ 50 nM[1]. Swinholide A is a microfilament disrupting marine toxin that stabilizes actin dimers and severs actin filaments. Swinholide A disrupts the actin cytoskeleton of cells.Antifungal activity[2].

体外研究
(In Vitro)

Swinholide A, first isolated from the Okinawan marine sponge Theonella swinhoei, dimerizes actin[1].
Swinholide A, isolated from the marien sponge Theonella swinhoei, is highly cytotoxic to a variety of cancer cell lines[2].
Swinholide A disrupts the actin cytoskeleton of cells grown in culture, sequesters actin dimers in vitro in both polymerizing and non-polymerizing buffers with a binding stoichiometry of one swinholide A molecule per actin dimer, and rapidly severs F-actin in vitro with high cooperativity[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[2]

Cell Line: Balb/c 3T3 and Swiss 3T3 cells
Concentration: 5-100 nM
Incubation Time: 1-24 h
Result: Exponentially growing cells exposed to 10 nM for 24 h became arborized with diffuse cytoplasmic staining and fluorescent punctate structures.
Partial cell retraction or arborization and diminution of microfilament bundles began after 2-4 h, with complete loss of stress fibers by 5-7 h at concentrations of 10-50 nM.
Caused rounding of cultured mouse embryo 3T3 fibroblast cells within 1 h at concentration of 80 nM.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
