The incorporation of R,R-1,2-diaminocyclohexane at C4 in a series of 2,4-diaminopyrimidines led to a number of ALK inhibitors in which optimized activity was achieved by conversion of the 2-amino group into a methanesulfonamide. Tumor growth inhibition was observed when an orally bioavailable analog was evaluated in a Karpas-299 tumor xenograft mouse model.
在一系列 2,4-二氨基嘧啶中，将 R,R-1,2-二氨基环己烷引入 C4 位，得到了一系列 ALK 抑制剂，其中通过将 2-氨基转化为甲磺酰胺，优化了活性。当在 Karpas-299 肿瘤异种移植小鼠模型中评估一种口服生物利用的类似物时，观察到肿瘤生长抑制。
