Catalog Number: 3973
Chemical Name: 4-[(1R,4Z,8E,10Z,12S,15R, 17R)-17-Hydroxy-5,12-dimethyl-3-oxo-2,16-dioxabicyclo[13.3.1]nonadeca-4,8,10-trien-17-yl)-2-thiazolidinone
Biological Activity
Reversible inhibitor of actin assembly; blocks actin adenine nucleotide exchange. Complexes with actin in vitro and interacts with actin monomers only, unlike cytochalasins. Prevents actin repolymerization into filaments and disrupts the actin cytoskeleton.
