TNG456
TNG456 is an orally active, CNS-penetrant, selective, MTA-cooperative PRMT5 inhibitor. TNG456 drives dose-dependent antitumor activity in mouse xenograft models. TNG456 can be used for the research of MTAP-null solid tumors, including gliomas, and CNS metastases.

Biological Activity
|
PRMT5 |
TNG456 (10 μM) exhibits high selectivity for PRMT5, with no significant activity against 40 other methyltransferases when tested at 10 μM[2].
TNG456 (7 days) inhibits the viability of HAP1 MTAP-null cells with a GI50 of 20 nM, and is 50-fold more selective for HAP1 MTAP-null cells than HAP1 MTAP WT cells[2].
TNG456 (7 days) inhibits the viability of MTAP-null LU99, LN18, HCT116, and HAP1 cells with GI50 values ranging from 0.015 μM to 0.054 μM, and shows an average 55-fold selectivity over their matched MTAP WT counterparts[2].
TNG456 exhibits favorable metabolic stability in human liver microsomes, with an intrinsic clearance of 13 μL/min/mg[2].

TNG456 (30-90 mg/kg; p.o.; BID) exhibits potent, durable antitumor activity across diverse mouse MTAP-null patient-derived xenograft models[2].
TNG456 (45-90 mg/kg; p.o.; BID) in combination with Abemaciclib (HY-16297A) delivers robust antitumor benefit in aggressive MTAP-null glioblastoma xenografts[2].
