Product Description
General description：
A cell-permeable pyrazolylthiazolo-isobutyramide compound that acts as a potent LIM kinase inhibitor (IC50 = 7 and 8 nM against LIMK1 and LIMK2, respectively) and effectively suppresses cellular cofilin phosphorylation (IC50 ~ 1 µM in A549 and MDA-MB-231 cultures) without affecting tubulin polymerization or inducing cytotoxicity (EC50 >10 µM in A549 proliferation and colony formation assays). Shown to effectively destabilize F-actin structure in MDA-MB-231 breast cancer cells (3 to 10 µM) with concomitant blockage of invadopedia-mediated ECM degradation (13% and 10% of control, respectively, by 3 and 10 µM inhibitor) and invasion (45% and 7% of control invasion rate, respectively, by 3 and 10 µM inhibitor). Although reported to exhibit affinity toward AMPKα1 and AMPKα2 in T7 phage-based competition binding studies, inhibitory activity of LIMKi 3 against AMPKα1/2 is not yet directly demonstrated.
