HOW DO IDH2 INHIBITORS WORK?

Isocitrate dehydrogenase 2 (IDH2) inhibitors are drugs used for treating some cancers.

IDH2 is a gene that makes an enzyme isocitrate dehydrogenase 2. This enzyme is mainly found in the mitochondria, which are the energy-producing centers of the cells. IDH2 enzyme is responsible for the production of a molecule called nicotinamide adenine dinucleotide phosphate (NADPH). NADPH is responsible for:

Mutation in the IDH2 gene is responsible for altering the function of the IDH2 enzyme. This results in the overproduction of metabolites and compounds that contributes to uncontrollable cell growth, leading to the development of tumors.

IDH2 inhibitors disrupt the overproduction of metabolites and compounds, thus preventing tumor and cancer cell formation.
