MedKoo CAT#: 407238

CAS#: 1359944-60-7 (HCl)

Description: MRT-83 is a novel potent antagonist of Smo. MRT-83 blocks Hedgehog (Hh) signaling in various assays with an IC50 in the nanomolar range, showing greater potency than the reference Smo antagonist cyclopamine. MRT-83 inhibits Bodipy-cyclopamine binding to human and mouse Smo. MRT-83 abrogates the agonist-induced trafficking of endogenous mouse or human Smo to the primary cilium of C3H10T1/2 or NT2 cells that derive from a pluripotent testicular carcinoma. MRT-83 efficiently antagonizes Hh signaling in vivo. MRT-83 will be useful for manipulating Hh signaling and may help develop new therapies against Hh-pathway related diseases.
