IGF-1R inhibitor NVP-AEW541 as the starting point, the benzyl ether back-pocket binding moiety was replaced with a series of 2-cyclic ether methyl ethers leading to the identification of novel achiral [2.2.1]-bicyclic ether methyl ether containing analogues with improved IGF-1R activities and kinase selectivities. Further exploration of the series, including a fluorine scan of the 5-phenyl substituent, and
以吡咯并嘧啶衍生的IGF-1R抑制剂NVP-AEW541为起点,用一系列2-环醚甲基醚取代苄基醚后口袋结合部分,从而鉴定出新的非手性[2.2.1]-双环醚包含具有改善的IGF-1R活性和激酶选择性的类似物的甲醚。对该系列的进一步探索,包括对5-苯基取代基的氟扫描以及对糖口袋结合部分的优化,确定了含有(S)-2-四氢呋喃甲基醚6-氟苯基醚后口袋和顺式-的化合物33 N -Ac-Pip糖口袋结合基团。化合物33 与NVP-AEW541相比,具有更好的选择性和药代动力学,并且在抑制小鼠中IGF-1R依赖性肿瘤异种移植模型的生长方面,产生了与林西替尼相当的体内功效。
