A cell-permeable pyrazolylthiazolo-isobutyramide compound that acts as a potent LIM kinase inhibitor (IC50 = 7 and 8nM against LIMK1 and LIMK2, respectively) and effectively suppresses cellular cofilin phosphorylation (IC50 ~1uM in A549 and MDA-MB-231 cultures) without affecting tubulin polymerization or inducing cytotoxicity (EC50 >10uM in A549 proliferation & colony formation assays). Shown to effectively destabilize F-actin structure in MDA-MB-231 breast cancer cells (3 to 10uM) with concomitant blockage of invasion (by 93% at 10uM).
Molecular Formula:C₁₇H₁₄Cl₂F₂N₄OS
Solubility:DMSO
Primary Target:LIMK1 and LIMK2
Primary Target IC50:7 and 8nM against LIMK1 and LIMK2, respectively
