Introduction of 944328-88-5 :

QS11 is an inhibitor of ARFGAP1 (ADP-ribosylation factor GTPase-activating protein 1), with an EC50 of 1.5 µM. QS11 modulates Wnt/β-catenin signaling through an effect on protein trafficking. QS11 inhibits migration of ARFGAP overexpressing breast cancer cells[1]. IC50 & Target: EC50: 1.5 µM (ARFGAP1)[1] In Vitro: QS11 binds and inhibits the GTPase activating protein of ARFGAP1, suggesting that QS11 modulates Wnt/β-catenin signaling through an effect on protein trafficking[1].
QS11 (2.5 μM) activates the Super(8X)TOPFlash reporter 200-fold in the presence of Wnt-3a conditioned medium, whereas Wnt-3a treatment alone increases reporter activity 40-fold[2].
QS11 shows potent activity (EC50=0.5 μM) with little cytotoxicity toward HEK293 and human primary fibroblast cells[2].
QS11 effectively reduces in vitro migration of metastatic human breast cancer cells[2].
