| Protocol | In Vitro | In vitro activity: Treatment with EPZ020411 results in a dose-dependent decrease in H3R2 methylation in A375 human melanoma cells exogenously overexpressing PRMT6(IC50=0.637±0.241 μM). In biochemical assays EPZ020411 is over 100-fold selective for PRMT6/8/1 compared to other histone methyltransferases including four arginine methyltransferases (PRMT3, PRMT4, PRMT5, and PRMT7). The compound shows poor permeability in the parallel artificial membrane permeation assay. Kinase Assay: EPZ020411 is a potent and selective inhibitor of PRMT6 with IC50 of 10 nM, has ＞10 fold selectivity for PRMT6 over PRMT1 and PRMT8. Cell Assay: A375 (CRL-1619) cells are cultured in DMEM plus 10% (vol/vol) FBS. PRMT6 is cloned into BamHI and EcoRI sites of a pcDNA4 HisMAX_A plasmid. Transfection of his-tagged PRMT6 or vector control is carried out using Lipofectamine LTX and Plus reagent according to procedures recommended by the manufacturer. Cells are seeded at 200,000 cells/well in 6-well plates. The following day, the cells are concurrently transfected and treated with compound in 0.25% DMSO. Cells are incubated in the presence of increasing concentrations of compound up to 20 μM. Cell pellets are collected after 48 hours of compound treatment. |

| In Vivo | EPZ020411 shows good bioavailability following subcutaneous dosing in rats making it a suitable tool for in vivo studies. Male Sprague-Dawley rats administered a single dose of EPZ020411 at 1 mg/kg by i.v. bolus show a moderate clearance (CL) of 19.7±1.0 mL/min/kg, with a volume of distribution at steady state (Vss) of 11.1±1.6 L/kg, translating to a mean terminal half-life (t1/2) of 8.54±1.43 h. Following 5 mg/kg s.c. dosing, a good bioavailability of 65.6 ± 4.3% is observed, leading to EPZ020411 unbound blood concentration remaining above the PRMT6 biochemical IC50 value for more than 12 h. |
