A library of pyrido[2,3-d]pyrimidines was designed as inhibitors of FGFR3 tyrosine kinase allowing possible interactions with an unexploited region of the ATP binding-site. This library was built-up with an efficient step of click-chemistry giving easy access to triazole-based compounds bearing a large panel of substituents. Among the 27 analogues synthesized, more than half exhibited 55–89% inhibition of in vitro FGFR3 kinase activity at 2 μM and one (19g) was able to inhibit auto-phosphorylation of mutant FGFR3-K650M in transfected HEK cells.
设计了一系列吡啶并[2,3-d]嘧啶类化合物作为FGFR3酪氨酸激酶的抑制剂,这些化合物可能与ATP结合位点的一个未开发区域发生相互作用。该化合物库通过高效的点击化学步骤构建,便于合成含有多种取代基的三唑类化合物。在合成的27个类似物中,超过一半的化合物在2微摩尔浓度下对体外FGFR3激酶活性表现出55-89%的抑制作用,其中一个化合物(19g)能够抑制转染HEK细胞中突变型FGFR3-K650M的自磷酸化。
