| Hazard Information | Back Directory | [Description]
Enasidenib (1446502-11-9) is a potent (IC50’s = 100 nM IDH2R140Q homodimer, 30 nM IDH2R140Q/WT heterodimer and 10 nM IDH2R172K/WT heterodimer) and selective inhibitor of mutant isocitrate dehydrogenase 2 (IDH2).1? It suppressed the production of the oncometabolite (R)-2-Hydroxyglutarate (a competitive inhibitor of αKG-dependent dioxygenases which leads to epigenetic dysregulation) and induced cellular differentiation in primary human IDH2 mutation-positive acute myeloid leukemia cells.1,2? Recently approved for clinical use by the FDA. | [Uses]
Enasidenib is a first-in-class oral selective inhibitor of mutant IDH2 enzymes (isocitrate dehydrogenase 2), for the treatment of adults with relapsed or refractory IDH2-mutated acute myeloid leukemia. | [Definition]
ChEBI: Enasidenib is a 1,3,5-triazine which is substituted by (2-hydroxy-2-methylpropyl)nitrilo, 6-(trifluoromethyl)pyridin-2-yl and [2-(trifluoromethyl)pyridin-4-yl]nitrilo groups at positions 2,4 and 6, respectively. It is an isocitrate dehydrogenase-2 (IDH2) inhibitor which has been approved for the treatment of adults with relapsed or refractory acute myeloid leukaemia (AML). It has a role as an antineoplastic agent and an EC 1.1.1.42 (isocitrate dehydrogenase) inhibitor. It is an aminopyridine, an organofluorine compound, a secondary amino compound, a tertiary alcohol, a member of 1,3,5-triazines and an aromatic amine. | [in vitro]
ag-221 was found to be able to reduce 2-hg levels by >90%, reverse in-vitro histone and dna hypermethylation, and induce differentiation in leukemia cell model as well. in addition, a dose dependent proliferative burst of the human specific cd45+ blast cells was observed by the treatment of ag-221, as measured by the expression of cd11b, cd14, cd15 and cell morphology [1]. | [in vivo]
the efficacy of ag-221 in a primary human aml xenograft model with the idh2 r140q mutation was studied, and the results showed that ag-221 could reduce 2-hg in the plasma, bone marrow, and urine of engrafted mice potently. in addition, the treatment of ag-221 could also induce a significant and dose dependent survival benefit as demonstrated by that all mice in the high dose treatment of ag-221 survived to the end of study [1]. | [IC 50]
