Design, synthesis, AML activity and molecular modeling of novel IDH2 inhibitors

Abstract

Enasidenib (AG-221) is the only approved IDH2 inhibitor, clinical study found Enasidenib have some side-effects. In this work, we synthesized series of novel s-triazine derivatives, and the in vitro and in vivo activity of anti-AML has been studied using AM7577 model. The cell activity found Ta and Th showed excellent inhibition to AM7577. We further used the HuKemia Acute Leukemia xenograft model to investigate the in vivo efficacy of compounds Ta and Th, compared with AG-221, although Ta and Th can't reduce the 2-HG level obviously, those two compounds can prolong the survival of rats. The research can expand the structure of novel IDH2 inhibitors and provide useful information for further research of novel AML drugs.
