Design, synthesis and biological evaluation of a series of novel pyrrolo[2,3-d]pyrimidin/pyrazolo[3,4-d]pyrimidin-4-amine derivatives as FGFRs-dominant multi-target receptor tyrosine kinase inhibitors for the treatment of gastric cancer
have recently been suggested as potential targets for gastric cancer treatment. We herein report the discovery of pyrrolo[2,3-d]pyrimidin/pyrazolo[3,4-d]pyrimidin-4-amine derivatives as a newclass of FGFRs-dominant multi-target receptor tyrosine kinase inhibitors. SAR assessment identified the most active compounds 8f and 8k, which showed excellent inhibitory activity against a variety of receptor tyrosine
胃癌是全球第二大致命癌症。随着治疗手段的进步,早期胃癌的5年生存率可达95%以上。然而,晚期胃癌的预后和生存时间仍然很严峻。因此,迫切需要更有效的胃癌治疗靶向疗法。FGFR、VEGFR 和其他受体酪氨酸激酶最近被建议作为胃癌治疗的潜在靶标。我们在此报告了吡咯并[2,3 - d ]嘧啶/吡唑并[3,4- d ]嘧啶-4-胺衍生物作为一类新型FGFRs-显性多靶受体酪氨酸激酶抑制剂的发现。SAR 评估确定了最活跃的化合物8f和8k,对多种受体酪氨酸激酶显示出极好的抑制活性。此外,8f和8k在 SNU-16 胃癌细胞系中表现出优异的效力。此外,8f和8k可以抑制 FGFR1 磷酸化和下游信号通路以及诱导细胞凋亡。在体内,8f和8k在 SNU-16 异种移植模型中抑制肿瘤生长,而不会引起明显的毒性。这些发现提高了化合物8f和8k可能作为治疗胃癌的潜在药物的可能性。
