IC50: 3 nM

EPZ031686 is the first SMYD3 inhibitor.

Set and Mynd Domain containing 3 (SMYD3), a lysine methyltransferase (KMT) expressed at high levels in a number of different cancer histologies, is reported to be associated with a poor clinical prognosis.

In vitro: EPZ031686 was the first SMYD3 inhibitor found to show double-digit nanomolar cellular activity. In addition, EPZ031686 displayed noncompetitive inhibition to both SAM and MEKK2 with a Ki = 1.2 and 1.1 nM, respectively. Moreover, EPZ031686 showed less than 30% inhibition against 16 histone methyltransferase targets at a 10 μM [1].

In vivo: Male mice i.v. administered a single dose of EPZ031686 at 1 mg/kg showed a moderate clearance of 27 mL/min/kg, which was in very good agreement with the microsomal data, with a volume of distribution at steady state of 2.3 L/kg, translating to a terminal half-life of 1.7 h. Around 20% of the administered dose was excreted unchanged in urine after 24 h, equivalent to a renal clearance of 5.3 mL/min/kg. Bioavailability of 48 and 69 was observed at 5 and 50 mg/kg, respectively, resulting in the EPZ031686 unbound blood concentration remaining above the SMYD3 IC50 value for more than 12 h after a 50 mg/kg p.o. administration [1].

Clinical trial: Up to now, EPZ031686 is still in the preclinical development stage.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
