| Hazard Information | Back Directory | [Uses]
Navlimetostat is a potent, orally active, selective PRMT5?MTA complex inhibitor, with IC50 of 3.6 and 20.5 nM for PRMT5?MTA and PRMT5. Navlimetostat binds to the PRMT5?MTA complex, with KD value of 0.14 pM. Navlimetostat shows antineoplastic activity in vitro and in vivo, and can be used for cancer study[1][2]. | [Biological Activity]
MRTX-1719 is a potent first-in-class selective inhibitor of the PRMT5/MTA complex, with an IC50 of less than 10 nM in PRMT5/MTA MTAPDEL SDMA cells[1]. | [in vivo]
Navlimetostat (12.5-100 mg/kg/d for p.o., 21 day) reduces the tumor growth in Lu-99 orthotopic xenograft tumor models[2].
