AbMole丨Ulixertinib:靶向ERK1/2通路的抑制剂的科研应用

AbMole丨Ulixertinib:靶向ERK1/2通路的抑制剂的科研应用 UlixertinibBVD-523AbMoleM5345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UlixertinibVRT752271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 CAS No.869886-67-9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UlixertinibCAS 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]。在肺癌研究中UlixertinibBVD-523可有效逆转RAD21驱动的转移尤其在KRAS突变背景下在小鼠模型中显著抑制肺腺癌LUAD进展[5]此外在脑转移模型中Ulixertinib能穿透血脑屏障并在小鼠中减少脑转移发生率、延长生存期[6]。药代动力学研究表明UlixertinibGemzar在小鼠、大鼠和犬中口服给药后吸收迅速半衰期介于1.0–2.5 h[7]。综合来看UlixertinibBVD-523AbMoleM5345凭借其明确的靶向机制、良好的体内暴露特性及广泛的协同潜力已成为解析MAPK通路功能及开发联合干预策略的重要科研工具。参考文献及鸣谢[1] Yu, Y.; Zhao, Y.; Choi, J. et al.
