SMIFH2 is an inhibitor of formin homology 2 (FH2) domains.{54322} It inhibits assembly of profilin-actin mediated by mouse formin mDia1(FH1FH2) with an IC50 value of approximately 15 ?M. It also inhibits actin assembly mediated by FH1FH2 constructs of mDia2, C. elegans CYK-1, S. pombe Cdc12 or Fus1, or S. cerevisiae Bni1. SMIFH2 (25 ?M) disassembles formin-dependent actin cables and contractile rings, but not Arp2/3-dependent actin patches, in fission yeast. It is cytotoxic to NIH3T3 fibroblasts (IC50 = 28 ?M). SMIFH2 (10 ?M) increases and decreases the percentage of NIH3T3 cells with thin and thick F-actin bundles, respectively.
