2-anilino-pyrimidine IGF-1R kinase inhibitors led to the identification of novel 2-(pyrazol-4-ylamino)-pyrimidines with improved physicochemical properties. Replacement of the imidazo[1,2-a]pyridine group of the previously reported inhibitor 3 with the related pyrazolo[1,5-a]pyridine improved IGF-1R cellular potency. Substitution of the amino-pyrazole group was key to obtaining excellent kinase selectivity and
一系列2-苯胺基-嘧啶IGF-1R激酶抑制剂中细胞亲脂性配体效率(LLE)的优化导致鉴定出具有改进的理化性质的新型2-(吡唑-4-基氨基)-嘧啶。用相关的吡唑并[1,5- a ]吡啶取代先前报道的抑制剂3的咪唑并[1,2- a ]吡啶基改善了IGF-1R的细胞效力。氨基吡唑基的取代是获得适用于口服给药的优异激酶选择性和药代动力学参数的关键,这导致发现(2 R)-1- [4-(4-[5-氯-4-(吡唑并[1,5- a ]吡啶-3-基)-2-嘧啶基]氨基} -3,5-二甲基-1 H-吡唑-1-基)-1-哌啶基] -2-羟基-1-丙酮(AZD9362,28),一种新型,IGF-1R的有效的抑制剂。
