hepatocellular carcinoma (HCC) with several pan-FGFR inhibitors and FGFR4-selective inhibitors currently being evaluated in the clinic. However, FGFR4 gatekeeper mutation induced acquired resistance remains an unmet clinical challenge for HCC treatment. Thus, a series of aminoindazole derivatives were designed and synthesized as new irreversible inhibitors of wild-type and gatekeeper mutant FGFR4. One
异常的 FGF19/FGFR4 信号传导已被证明是人类肝细胞癌 (HCC) 生长和存活的致癌驱动因素,目前临床上正在评估几种泛 FGFR 抑制剂和 FGFR4 选择性抑制剂。然而,FGFR4 看门人突变诱导的获得性耐药仍然是 HCC 治疗尚未解决的临床挑战。因此,设计并合成了一系列氨基吲唑衍生物作为野生型和看门人突变FGFR4的新的不可逆抑制剂。一种代表性化合物 ( 7v ) 在生化和细胞测定中均表现出优异的抗 FGFR4、FGFR4 V550L和 FGFR4 V550M的效力,具有纳摩尔活性,同时保留了 FGFR1/2/3。虽然化合物7v表现出适度的在携带 Huh-7 异种移植模型的裸鼠中的体内抗肿瘤功效与其不利的药代动力学特性一致,它为未来的药物发现提供了一个有希望的新起点,以对抗 HCC 患者中 FGFR4 看门人介导的耐药性。
