A-893 is a cell-active inhibitor of Methyltransferase SMYD2, with an IC50 of 2.8 nM.

IC50 & Target

IC50: 2.8 nM (SMYD2)[1].

In Vitro

The ratio of p53K370me1 to overall p53 levels is reduced, as expected, by treatment with either A-893 or AZ505. While this unexpectedly depicts a more robust response with AZ505, further dissection of the data provides clarity into the origin of this. While overall p53 levels are unaffected by A-893, a surprising >3-fold increase is observed with AZ505. Analysis of p53K370me1 levels reveals that inhibitor A-893 exhibited 42% reduction in the methyl mark, while AZ-505 is slightly less effective at 28% reduction[1].

Cell Assay

Human A549 lung carcinoma cells are chosen due to their high SMYD2 expression levels and wild-type p53 status. After 18 h of treatment with 10 μM of compound (e.g. A-893), changes in p53K370me1 are measured along with changes to overall p53 levels[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
