1-oxo-3-aryl-1H-indene-2-carboxylic acid derivatives as selective inhibitors of fibroblast growth factor receptor-1 tyrosine kinase

Fibroblast growth factor receptor (FGFr) mediated signal transduction is implicated in vascular proliferative diseases and some cancers. We have identified methyl 1-oxo-3-phenyl-1H-indene-2-carboxylic ester as a small molecule inhibitor of the tyrosine kinase activity of FGFr-1, (IC50 = 5.1 mu M). We report here the synthesis and structure-activity studies about this template core. Additionally, screening of this series against a panel of tyrosine kinases shows selective inhibition of FGFr.
