A series of novel 3-(indol-3-yl)-4-(pyrazolo[3,4-c]pyridazin-3-yl)maleimides were synthesized and evaluated for their inhibitory activity against mutant isocitrate dehydrogenase-1 (R132H). Most compounds exhibited potent potency to IDH1-R132H. Among them, compound9bwas the most promising IDH1-R132H inhibitor with IC50 values of 31 nmol/L and could significantly inhibit the production of 2-HG in human brain astroblastoma cells with mutant isocitrate dehydrogenase-1 (R132H). Preliminary structure-activity relationship and molecular modeling studies were discussed based on the experimental data obtained.

Key words: 3-(indol-3-yl)-4-(pyrazolo[3,4-c]pyridazin-3-yl)maleimide, mutant isocitrate dehydrogenase-1 (R132H) inhibitor, synthesis, biological activity
