Chemical Name: (±)-1,2,3,3a-Tetrahydro-3a-hydroxy-6-methyl-1-phenyl-4H-pyrrolo[2,3-b]quinolin-4-one

Biological Activity

Selective inhibitor of myosin II ATPase activity; inhibits contraction of the cleavage furrow without disrupting mitosis or contractile ring assembly. Rapidly and reversibly blocks cell blebbing, and disrupts directed cell migration and cytokinesis in vertebrate cells.

Technical Data

Soluble to 100 mM in DMSO
>98 %
Store at +4°C
