Design, synthesis and biological evaluation of N-phenylthieno[2,3-d]pyrimidin-4-amines as inhibitors of FGFR1

Our paper dedicated to the development of novel class of inhibitors for protein kinase FGFR1 has been published in Bioorganic and Medicinal Chemistry.  

Abstract: Fibroblast grow factor receptor 1 (FGFR1) is an important anti-cancer target that plays crucial role in oncogenesis and oncogenic angiogenesis. The structure-activity relationship (SAR) of N-phenylthieno[2,3-d]pyrimidin-4-amines was investigated. Binding of active compounds with FGFR1 kinase was analyzed by molecular modeling studies. Selected active thieno[2,3-d]pyrimidines were tested for selectivity and antiproliferative activity. The most active compounds, 3-({6-phenylthieno[2,3-d]pyrimidin-4-yl}amino)phenol and 3-({5-phenylthieno[2,3-d]pyrimidin-4-yl}amino)phenol have IC₅₀ 0.16 and 0.18 μM, respectively. The results presented here may help to identify new thienopyrimidines with optimized cell growth inhibitory activity which may be further used as anticancer agents.
