Biological Activity

Description LLY-507 is a cell-active, potent, and selective inhibitor of protein-lysine Methyltransferase SMYD2.
SMYD2 [1]
In vitro

LLY-507 potently inhibits the ability of SMYD2 to methylate p53 peptide with an IC50 <15 nM. LLY-507 is able to potently inhibit the methylation of H4 peptide by SMYD2 enzyme with an IC50 of 31 nM. It has 100-fold selectivity for SMYD2 over 24 other protein or DNA methyltransferases including related family members SMYD3, SUVH420H1, and SUV420H2. LLY-507 inactives (>20 μM) against 454 kinases, 35 G protein-coupled receptors, 14 nuclear hormone receptors, and three cytochrome P450 enzymes. LLY-507 inhibits the proliferation of several esophageal, liver, and breast cancer cell lines in a dose-dependent manner[1].

Protocol (from reference)

Cell Research:


  • Cell lines: HEK293 cells
  • Concentrations: 0-2.5 μM
  • Incubation Time: 28 h
  • Method:

    To examine the methylation status of p53 in HEK293 cells treated with LLY-507 by Western blotting, 2 × 105 cells are seeded in 6-well plates in triplicate and co-transfected with FLAG-tagged p53 and FLAG-tagged SMYD2 using Lipofectamine® 2000. The day after transfection, cells are treated with 0-2.5 μM LLY-507 for 28 h, then collected, and lysed in radioimmunoprecipitation assay (RIPA) buffer. Cell lysates are subject to 10% SDS-PAGE and transferred to a PVDF membrane.

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.
