CK869 is an inhibitor of actin polymerization, it functions by inhibiting the actin-related protein 2/3 (Arp2/3) complex and reduced cell motility rate and rearrangement of F-actin in M-1 cells.

CK-636 is an Arp2/3 complex inhibitor with IC50 of 4 μM, 24 μM and 32 μM for inhibition of actin polymerization induced by human, fission yeast and bovine Arp2/3 complex, respectively.

CK 666 is an inhibitor of Arp2/3 complex. It can inhibit actin polymerization (IC50 = 4 μM).

SMIFH2 is an inhibitor of formin homology 2 (FH2) domains.

Cytochalasin B, a metabolite of the fungus Drechslera dematoidea, is an cell-permeable inhibitor of actin polymerization which inhibits cell division, migration and glucose transport and causes G2/M cell cycle arrest and apoptosis in HCT-116 colorectal carcinoma cells.

Benproperine Phosphate is an ARPC2 (Actin-related protein 2/3 complex subunit 2) inhibitor which works as an inhibitor of cancer cell migration and an anti-metastatic agent.

Latrunculin A is a reversible and selective inhibitor of actin assembly. It can block actin adenine nucleotide exchange.
