In vitro
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.
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.
