EPZ-6438 is a potent, and selective EZH2 inhibitor with Ki and IC50 of 2.5 nM and 11 nM, exhibiting a 35-fold selectivity versus EZH1 and >4,500-fold selectivity relative to 14 other HMTs.
|Source||Cell Rep (2016). Figure 1. EPZ-6438|
|Concentrations||500 nM or 5 μM|
|Incubation Time||4 or 9 days|
|Results||This loss in viability explains the apparent decrease in detection of total H3 at higher EPZ-6438 doses. It is interesting to note that this loss of H3 detection occurs at higher doses (100–500 nM) than doses required to reduce relative H3K27me3 (10–100 nM).|

|Animal A (mg/kg) = Animal B (mg/kg) multiplied by||Animal B Km|
|Animal A Km|
For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
|Solubility||DMSO 10 mg/mL|
