LLY-507 (multiple off-targets)

LLY-507 (multiple off-targets) A chemical probe for SMYD2 protein lysine methyltransferase

This probe is available from Cayman ChemicalTocris and Sigma


A collaboration between the SGC and Eli Lilly and Company has resulted in the discovery of LLY-507, a chemical probe for SMYD2 (a protein lysine methyltransferase). LLY-507 is a potent inhibitor of SMYD2 with in vitro IC50 <15 nM and >100-fold selectivity over other methyltransferases and other non-epigenetic targets. LLY-507 has been shown to inhibit p53K370 monomethylation in cells with an IC50 ~600 nM. 

Note: After LLY-507 was released, off-target screening (in addition to those presented in the publication, doi:10.1074/jbc.M114.626861) was done. Here is a copy of the report from a functional screen of LLY-507 and its control SGC705 in the NIMH Psychoactive Drug Screening Program (PDSP). This report clearly shows more than 50% inhibition of a number of targets.
