VRT752271 (BVD-523; VRT752271) 是一种有效的、具有口服活性、高度选择性、ATP 竞争性和可逆的 ERK1/2 激酶共价抑制剂，对 ERK2 的 IC50 <0.3 nM。 VRT752271 (BVD-523; VRT752271) 抑制 A375 黑色素瘤细胞系中的磷酸化 ERK2 (pERK) 和下游激酶 RSK (pRSK)。
Ulixertinib (BVD-523; VRT752271) is a potent, orally active, highly selective, ATP-competitive and reversible covalent inhibitor of ERK1/2 kinases, with an IC50 of <0.3 nM against ERK2. Ulixertinib (BVD-523; VRT752271) inhibits the phosphorylated ERK2 (pERK) and downstream kinase RSK (pRSK) in an A375 melanoma cell line[1][2].
In the pharmacokinetic study, the sensitivity and specificity of the assay are found to be sufficient for accurately characterizing the plasma pharmacokinetics of Ulixertinib (VRT752271) in Balb/C mice[2].
