Inhibition of FLT3 and PDGFR tyrosine kinase activity by bis(benzo[b]furan-2-yl)methanones.


A series of bis(benzo[b]furan-2-yl)methanones was synthesized and tested for inhibition of FLT3 and PDGFR autophosphorylation. Mostly, C-5 substitution leads to PDGFR selectivity, which was strongest in the case of the 5,5'-dimethoxy derivative. The 5,5'-diamino and the 6,6'-dihydroxy compounds are more active at FLT3. At both kinases, the potency of the… (More)
