Benzo[e]isoindole-1,3-diones as potential inhibitors of glycogen synthase kinase-3 (GSK-3). Synthesis, kinase inhibitory activity, zebrafish phenotype, and modeling of binding mode.
Benzo[e]isoindole-1,3-dione derivatives were synthesized, and the effects on GSK-3beta activity and zebrafish embryo growth were evaluated. A series of derivatives show obvious inhibitory activity against GSK-3beta. The most potent inhibitor, 7,8-dimethoxy-5-methylbenzo[e]isoindole-1,3-dione (8a), shows nanomolar IC(50) and obvious phenotype on zebrafish embryo growth associated with the inhibition of GSK-3beta at low micromolar concentration. The interaction mode between 8a and GSK-3beta was characterized by computational modeling.
