Two new series of C-nucleosidic ATP mimics have been synthesized using an efficient and versatile synthetic pathway. These compounds were designed as FGFR3 inhibitors using purine as a central scaffold. The two substituents, a polyhydroxylated ribose mimic and a lipophilic moiety, were linked either in position 2 or 6 of the purine ring in order to explore any possible binding mode. All the compounds
已经使用一种有效且通用的合成途径合成了两个新系列的C-核苷ATP模拟物。使用嘌呤作为中心支架,将这些化合物设计为FGFR3抑制剂。为了研究任何可能的结合方式,两个取代基,即多羟基化的核糖模拟物和亲脂性部分,在嘌呤环的2或6位连接。所有化合物都能够在浓度为50μM的情况下抑制FGFR3激酶活性。出乎意料的是,发现最好的抑制剂是位置2上带有碘原子的合成中间体13之一。对接研究证实了其在ATP结合位点的位置,并揭示了关键相互作用之间的卤素键。
