A series of 2-aminopyrimidine derivatives were designed and synthesized as highly selective FGFR4 inhibitors. One of the most promising compounds 2n tightly bound FGFR4 with a Kd value of 3.3 nM and potently inhibited its enzymatic activity with an IC50 value of 2.6 nM, but completely spared FGFR1/2/3. The compound selectively suppressed proliferation of breast cancer cells harboring dysregulated FGFR4
设计并合成了一系列2-氨基嘧啶衍生物,作为高选择性FGFR4抑制剂。最有希望的化合物2n紧密结合FGFR4,其Kd值为3.3 nM,并以2.6 nM的IC50值有效抑制其酶促活性,但完全避免了FGFR1 / 2/3。该化合物选择性抑制带有FGFR4信号传导失调的乳腺癌细胞的增殖,IC50值为0.38μM。此外,2n在针对468个激酶的全基因组筛选中显示出非凡的靶标特异性,在1.0μM时S(35)和S(10)的选择性得分分别为0.01和0.007。
