Jasplakinolide is a naturally occurring cyclo-depsipeptide. It was first isolated from a species of marine sponge named Jaspis johnstoni. It is permeable to the cell membrane meaning that it is able to cross the membrane.¹ Once it crosses the cell membrane, it is a potent inducer and stabilizer of actin filaments meaning that it rapidly stabilizes pre-existing filaments and polymerize the protein actin.² It also inhibits the disassembly of theses filaments. When doing this, it competes with phalloidin making it unable to bind with F-actin.³

Applications

Jasplakinolide is potentially important in medical applications showing anti-cancer, fungicidal and antiproliferative properties. It also has important scientific applications for the study of organelles, and actin filaments.¹²⁴
