Description
技术领域
本发明涉及药物技术领域,具体涉及一种靶向粘着斑激酶的化合物及制备方法和应用。
技术背景
粘着斑激酶(Focal adhesion kinase,Fak)在肿瘤的侵袭和转移中起着关键作用,是一种细胞质酪氨酸激酶,参与细胞的多种功能,在肿瘤细胞的侵袭、转移、血管生成和信号转导等方面具有重要的作用,并且在各种肿瘤细胞中过表达,并与肿瘤细胞的恶性程度相关,所以可以成为肿瘤诊断的分子标志物,FAK位于整合素和受体酪氨酸激酶信号转导交汇点,可以将细胞外基质的信号传递到细胞内,抑制FAK的功能可以有效的阻断一些与肿瘤相关的信号通路。FAK的过表达可能与其基因扩增有关联,同时也被证明在细胞存活、迁移和侵袭中发挥重要的作用。因此,FAK成为肿瘤诊疗的一个重要靶点。

表1标准品化合物的体外FAK酶活性抑制实验结果
二、本发明的FAK抑制剂在联合用药方面的优势,通过与不同药物的联合在治疗肺癌、肝癌、卵巢癌、胰腺癌、结肠癌、前列腺癌、脑胶质瘤等但不限于这几种癌症中取得较好结果,如可以联合埃罗替尼、克唑替尼、恩曲替尼、凡德他尼、达拉非尼、拉罗替尼用于肺癌的治疗;如可以联合紫杉醇或卡铂用于卵巢癌的治疗;如可以联合吉西他滨、卡培他滨、帕博利珠单抗、紫杉醇等用于胰腺癌的治疗;如可以联合紫杉醇、铂类药物等用于食管癌的治疗等但不限于这几种联合方式,其均表现出比单一用药更好的抑瘤效果。例如化合物LY-21在A549异种移植模型中的抑瘤效果如图1和图2所示,可以看出化合物LY-21联合埃罗替尼在肺癌小鼠模型中,表现出比单一用药更好的抑瘤效果,而且小鼠的活泼程度也很好,体重也不减少,说明毒性小,能达到1+1大于2的效果。由此可见,本发明的FAK抑制剂在联合用药方面具有非常重要的意义。
本发明的FAK抑制剂在单独用药方面的优势,包括在治疗肺癌、肝癌、卵巢癌、胰腺癌、结肠癌、前列腺癌、脑胶质瘤等但不限于这几种癌症。例如化合物LY-3在A549异种移植模型中的抑瘤效果如图3和图4所示,可以看出在A549异种移植模型中本发明的化合物LY-3在单独用药方面优于FAK临床药物VS-6063,且优于当前治疗肺癌上市药物埃罗替尼,其单一用药效果很好。
本发明的FAK抑制剂具有增加放射性诊断方面的优势,以化合物LY-10为例,在A549肿瘤模型中的显像图如图5所示,可以很清晰的看到我们所标记的FAK抑制剂在肿瘤部位具有较高的摄取,可以很清晰的分辨靶与非靶部位,且在肿瘤部位1具有较好的滞留。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内所作的任何修改、等同替换或改进等,均应包含在本发明的保护范围之内。
