 Use of JK-273


A small molecule inhibitor of α4 integrin-dependent cell migration (IC50=0.5 uM, on the motility of Jurkat T cells) that functions by interacting with γ-parvin; inhibits α4 integrin signaling, shows a selective cytotoxic effect against HCI-H460 NSCLC cells with IC50 of 0.98 uM, less sensitivity to fibroblasts (30-fold selectivity), causes cell cycle arrest at S phase and induces apoptosis.
