Design, synthesis and characterization of N9/N7-substituted 6-aminopurines as VEGF-R and EGF-R inhibitors
摘要:
In this study we report on the design, synthesis and biological characterization of novel N-9 or N-7 arylethanone-substituted 6-aminopurines and 6-methoxypurines, respectively, as EGF-R and VEGF-R. inhibitors. The compounds were initially profiled in a panel of 24 cancer-relevant protein kinases. Dependent on the regio-substitution of the purine core we found inhibition activity for EGF-R. and VEGF-R with IC50 values in the mu M range. The two novel N-9/N-7 2-(6-amino-purine)-1-(1H-indole-3-yl)ethanone derivatives were characterized in an enhanced panel of 78 kinases showing the N-9 derivative to also inhibit MNK1 and IRR while the N-7 isomer was found to be specific for VEGF-R2.
