Hh Signaling Antagonist VII, JK184 is an imidazopyridine compound that inhibits the Hedgehog (Hh) signaling pathway. JK184 is described to directly interact with tubulin subunits and prevent their polymerization into filaments, affecting the Hh pathway by destabilizing microtubules and modulating the microtubule-dependent mechanisms regulating function of the Gli transcription factors. JK184 is also described to inhibit Adh7 (alcohol dehydrogenase 7) activity, a function suggested to be ancillary to the effects of JK184 on microtubules and the Hh pathway.
