Biological Activity: 

JK184 is a potent and cell-permeable inhibitor of hedgehog (Hh) signaling downstream of Smo, identified by a cell-based Hh pathway reporter screening. JK184 was found to inhibit Adh7 (IC50 ~210 nM), the class IV alcohol dehydrogenase as well as act as a microtubule depolymerizing agent in vitro. JK184 inhibits Hh agonit-induced Gli transcriptional activity (IC50 ~30 nM) as well as Gli1 and Ptc1 mRNA expression in a dose-dependent manner in 10T1/2 cells. It shows antiproliferative activity in a range of cancer cell lines (IC50 ~ 3 - 21 nM), and inhibits the growth of two xenografted tumors in mice in vivo.


How to Use: 


  • In vitro: JK184 was suggested to use at 1-5 µM concentration in vitro and in the cellular assays.
  • In vivo: JK184 was dosed orally 0.2 mg/mouse once per day.
