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.
