ERK5-IN-1 is a potent selective ERK5 inhibitor, inhibiting EGFR-induced ERK5 autophosphorylation and ERK5 enzymatic activity. Orally bioavailable.

xmd17-109 is a new inhibitor of erk5, ic50 value in hela cell is 0.09 ± 0.03 μm, and in vitro, enzymatic ic50 value is 0.162 ± 0.006 μm.xmd17-109 is capable of inhibiting the erk5 autophosphorylation in cells.[1]through intravenous injection and oral delivery of xmd17-109 in mice, the pharmacokinetic properties of this compound are as bellows: the t1/2 (half time) is 8.2 h, the plasma clearance is 8.64 ml/min/kg (data of intravenous injection), the auc (area under the curve) of oral delivery is 15745 h*ng/ml and the oral bioavailability is 90%.

ERK5: 162 nM (IC₅₀); LRRK2[G2019S]: 339 nM (IC₅₀)
