ERK5:162 nM (IC50)

LRRK2[G2019S]:339 nM (IC50)

XMD17-109 (Compound 26) inhibits ERK5 biochemically with an IC50 of 0.162 ± 0.006 μM, and blocks pidermal growth factor induced ERK5 autophosphorylation with an EC50 of 0.09 ± 0.03 μM in cells. XMD17-109 also inhibits LRRK2[G2019S] with an IC50 of 339 nM[1]. XMD17-109 demonstrats low nanomolar cellular activity judged by the significant dose-dependent reduction of mobility shifted phosphorylated ERK5 bands from sorbitol stimulated cells. XMD17-109 completely inhibits the ERK5-mediated AP1 transcriptional activity at 30 μM and has an EC50 of 4.2 μM[2].

HeLa cells are maintained in DMEM supplemented with 10% FBS, 2 mM l-glutamine, 50 U/mL penicillin G, and 50 μg/mL streptomycin. Before use HeLa cells are serum starved for 16 h in DMEM supplemented with 2 mM l-glutamine, 50 U/mL penicillin G, and 50 μg/mL streptomycin. HeLa cells are then incubated with ERK5-IN-1 at the indicated concentrations for 1 h prior to stimulation with 0.5mol/Lsorbitol for 30 min. Cells are lysed in Triton lysis buffer (50 mM Tris-HCl, pH 7.5, 1 mM EGTA, 1 mM EDTA, 1 mM sodium orthovanadate, 50 mM sodium fluoride, 1 mM sodium pyrophosphate, 0.27mol/Lsucrose, 1 μM microcystin-LR, 1% (v/v) Triton X-100, 0.1% (v/v) 2-mercaptoethanol) and 20 μg of protein loaded per well. Samples are run on 8% polyacrylamide gels using standard methods. Proteins are transferred onto nitrocellulose membranes and specific proteins detected by immunoblotting.
