Ulixertinib(BVD-523,AbMole,M5345)是一种高选择性、可逆的细胞外信号调节激酶ERK1/2抑制剂,在多种细胞和动物模型中展现出显著的靶向抑制活性。在神经母细胞瘤(NB)研究中,Ulixertinib在低纳摩尔浓度范围内即可有效抑制MAPK通路的活性,并显著降低SK-N-BE(2)、IMR-32等NB细胞系的细胞增殖与集落形成能力,同时还能诱导细胞周期阻滞并促进凋亡、增强NB细胞对阿霉素(Doxorubicin)的敏感性[1]。在胶质瘤模型中,针对携带KIAA1549:BRAF融合或BRAFV600E突变的BT40和DKFZ-BT66细胞系,Ulixertinib(VRT752271)在体外以低纳摩尔浓度抑制细胞活力,并在斑马鱼胚胎和小鼠体内模型中证实其靶点抑制效应及抗肿瘤作用[2]。
在横纹肌肉瘤(RMS)研究中,
Ulixertinib(BVD-523,AbMole,M5345)与MCL-1抑制剂S63845联用可在体外快速诱导Caspase活化及凋亡,并在小鼠模型中显著抑制RMS细胞的长期存活,机制上涉及BIM和BMF的上调[3]。在胰腺导管腺癌(PDAC)细胞系如MIA PaCa-2和PANC-1中,Ulixertinib(CAS No.:869886-67-9)单一处理能有效抑制生长,并在与吉西他滨(Gemcitabine)联用时表现出协同细胞毒性[4]。

体内实验的工作液,建议现用现配,当天使用;如在配制过程中出现沉淀、析出现象,可以通过超声和(或)加热的方式助溶。
切勿一次性将产品全部溶解。
建议制定动物给药及实验方案时,尽量参考已发表的相关实验文献(溶剂种类及配比众多,简单地溶解目的化合物,并不能解决动物给药依从性、体内生物利用度、组织分布等相关问题,未必能保证目的化合物在动物体内充分发挥生物学效用)。
