The insulin-like growth factor-1 receptor (IGF1R) and closely related insulin receptor (INSR) are receptor tyrosine kinases which have been postulated to play a role in the tumorigenesis of certain cancers. Strategies for inhibiting oncogenic signalingvia the IGF1R and INSR include IGF1R antibodies, IGF1/2 antibodies and dual IGF1R/INSR tyrosine kinase inhibitors (TKIs). IGF1R/INSR TKIs linsitinib
胰岛素样生长因子-1受体(IGF1R)和紧密相关的胰岛素受体(INSR)是受体酪氨酸激酶,已被假定在某些癌症的肿瘤发生中起作用。通过途径抑制致癌信号的策略IGF1R和INSR包括IGF1R抗体,IGF1 / 2抗体和双重IGF1R / INSR酪氨酸激酶抑制剂(TKI)。IGF1R / INSR TKIs linsitinib(OSI-906)和BMS-754807已进入癌症患者的II / III期临床研究。我们在这里描述了我们的努力,以开发基于氨基嘧啶结构类别的IGF1R / INSR受体激酶的小分子双重抑制剂。我们的主要研究重点是通过调节理化特性并使用匹配的分子对方法和hERG同源性模型引入关键的结构基序,来并行优化细胞效价和脱靶活性(主要是hERG抑制)。
