Biological Activity for Jasplakinolide

Jasplakinolide rapidly stabilizes pre-formed actin filaments and inhibits their disassembly in vitro. Also induces polymerization of actin monomers into F-actin in vivo. Shown to bind to F-actin competitively with phalloidin (Cat. No. 4535) (Kd ~ 15 nM). Exhibits antifungal and antiproliferative effects (IC50 = 35 nM for antiproliferative activity in PC3 cells). Cell permeable.
