Chemical Name: Cyclo[(3R)-3-(4-hydroxyphenyl)-β-alanyl-(2S,4E,6R,8S)-8-hydroxy-2,4,6-trimethyl-4-nonenoyl-L-alanyl-2-bromo-N-methyl-D-tryptophyl]

Biological Activity

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.

Technical Data
