Application

Octyl-(R)-2 hydroxyglutarate (HG) has been used as a membrane permeamble oncometabolite in gliblostoma cells to test its effects on NANOG transcription factor expression. It has also been used as a competitive inhibitor of the enzyme α-ketoglutarate (α-KG)-dependent deoxygenase.

Biochem/physiol Actions

Octyl-(R)-2HG (Octyl-D-2HG) is a membrane-permeant precursor form of the oncometabolite D-2-hydroxyglutarate (D-2HG) produced by tumor cells due to mutations in the NADP+-dependent isocitrate dehydrogenase genes IDH1 and IDH2. D-2HG inhibits multiple α-ketoglutarate/α-KG-dependent dioxygenases by competing against α-KG binding. Cellular D-2HG delivery by Octyl-(R)-2HG treatment (1-50 mM) is shown to suppress demethylase activity (~148% H3K9me2 and ~310% H3K79me2 upregulation; 50 mM in U-87MG) as well as increase HIF-1α and decrease endostatin levels as a result of inhibiting α-KG-dependent dioxygenases prolyl hydroxylases (PHDs) and collagen prolyl-4-hydroxylase (C-P4H), respectively.

Preparation Note

The density is not reported for this compound. The molecular weight is 260.33. The solubility is tested at 2mg/mL in DMSO, however other sources suggest that it is soluble in DMSO up to 10mg/mL.

Mutations in the cytosolic NADP(+)-dependent isocitrate dehydrogenase (IDH1) occur in several types of cancer, and altered cellular metabolism associated with IDH1 mutations presents unique therapeutic opportunities. By altering IDH1, these mutations target a critical step in reductive glutamine metabolism, the

By impairing histone demethylation and locking cells into a reprogramming-prone state, oncometabolites can partially mimic the process of induced pluripotent stem cell generation. Using a systems biology approach, combining mathematical modeling, computation, and proof-of-concept studies with live cells, we found
