CAS#: 1428307-52-1 (HCl salt); 1428315-82-5 (free base).

Description: MRT-92 is a potent and selective Smoothened (Smo) receptor inhibitor. MRT-92 displays subnanomolar antagonist activity against Smo in various Hh cell-based assays. MRT-92 inhibits rodent cerebellar granule cell proliferation induced by Hh pathway activation through pharmacologic (half maximal inhibitory concentration [IC50] = 0.4 nM) or genetic manipulation. Smo is the target of anticancer drugs that bind to a long and narrow cavity in the 7-transmembrane (7TM) domain.
