MedKoo CAT#: 206194

CAS#: 1628805-46-8

Description: IDH305 is an inhibitor of the citric acid cycle enzyme isocitrate dehydrogenase [NADP] cytoplasmic (isocitrate dehydrogenase 1; IDH1) with mutations at residue R132 (IDH1(R132)), with potential antineoplastic activity. Upon administration, IDH305 specifically inhibits IDH1(R132) mutant forms in the cytoplasm, which inhibits the formation of the oncometabolite 2-hydroxyglutarate (2HG). This may lead to both an induction of cellular differentiation and an inhibition of cellular proliferation in IDH1(R132)-expressing tumor cells.

Additional Information

  IDH1(R132) mutations are highly expressed in certain malignancies, including gliomas. They initiate and drive cancer growth by both blocking cell differentiation and catalyzing the formation of 2HG
