PRMT5-IN-56
PRMT5-IN-56 is a PRMT5⋅MTA complex inhibitor with an IC50 of 0.2 nM, oral activity, and blood-brain barrier penetration. PRMT5-IN-56 inhibits PRMT5 methyltransferase activity in an MTA-cooperative manner, suppresses symmetrical dimethylarginine levels in MTAP-deficient cells. PRMT5-IN-56 suppresses proliferation of MTAP-deleted cancer cells with high selectivity over MTAP-wild type cells. PRMT5-IN-56 induces dose-dependent tumor growth inhibition in subcutaneous xenograft models, inhibits intracranial tumor progression, and prolongs survival in orthotopic brain xenograft models. PRMT5-IN-56 exhibits high intrinsic permeability, good oral bioavailability, and a high brain-to-plasma ratio. PRMT5-IN-56 can be used for the research of MTAP-deleted cancers and glioblastoma.

PRMT5-IN-56 (compound 21) (6 days) potently and selectively inhibits the proliferation of MTAP-deleted HCT116 cells with an IC50 of 1.1 nM, showing 214-fold selectivity over MTAP-wild type HCT116 cells[1].
PRMT5-IN-56 (6 days) preferentially suppresses the proliferation of MTAP-deleted cancer cells over MTAP-wild type cells across a diverse panel of cancer lines, and demonstrates superior potency over TNG462 (HY-156680) in multiple MTAP-deleted models[1].
PRMT5-IN-56 potently and selectively reduces symmetrical dimethylarginine (SDMA) levels in a concentration- and time-dependent manner in MTAP-deleted HCT116, LN18, and U87MG cells, with more rapid and profound effects than TNG462 (HY-156680) in glioma cell lines[1].
PRMT5-IN-56 (10 μM; 95 min) exhibits high intrinsic membrane permeability with a Papp of 16.94 × 10-6 cm/s and a low efflux ratio of 1.12 in a Caco-2 cell assay[1].
PRMT5-IN-56 (1 μM) exhibits good metabolic stability in human hepatocytes (T1/2 = 118.7 min) and moderate stability in mouse hepatocytes (T1/2 = 62.2 min)[1].
