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 μM). We report here the synthesis and structure-activity studies about this template core. Additionally, screening of this series against a panel of tyrosine kinases ...
