应用
辛基-（R）-2羟基戊二酸酯（HG）已被用作胶质母细胞瘤细胞中的膜渗透性致癌代谢物（oncometabolite），用于测试其对NANOG转录因子表达的影响。它还被用作酮戊二酸酯（α-KG）依赖性脱氧酶α的竞争性抑制剂。
生化/生理作用
抑制 α-酮戊二酸/α-KG 依赖性双加氧酶类的肿瘤代谢产物 D-2-羟基戊二酸的膜渗透前体形式。
辛基-(R)-2HG (Octyl-D-2HG) 是肿瘤细胞因 NADP + 依赖性异柠檬酸脱氢酶基因 IDH1 和 IDH2 突变而产生的肿瘤代谢产物 D-2-羟基戊二酸盐 (D-2HG) 的膜渗透前体形式。D-2HG 通过与 α-KG 结合竞争抑制多种 α-酮戊二酸/α-KG-依赖性双加氧酶。通过 Octyl-(R)-2HG 处理 (1-50 mM) 的细胞 D-2HG 传递显示出抑制脱甲基酶活性（~148%H3K9me2 和 ~310%H3K79me2 上调；U-87 mg 中 50 mm）以及因为分别抑制 α-KG-依赖性双加氧酶脯氨酰羟化酶 (PHD) 和胶原脯氨酰-4-羟化酶 (C-P4H)而增加 HIF-1α通过, 降低内皮抑素水平。

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

2-Hydroxyglutarate (2HG) exists as two enantiomers, (R)-2HG and (S)-2HG, and both are implicated in tumor progression via their inhibitory effects on α-ketoglutarate (αKG)-dependent dioxygenases. The former is an oncometabolite that is induced by the neomorphic activity conferred by isocitrate dehydrogenase

Enchondromas are benign cartilage tumors and precursors to malignant chondrosarcomas. Somatic mutations in the isocitrate dehydrogenase genes (IDH1 and IDH2) are present in the majority of these tumor types. How these mutations cause enchondromas is unclear. Here, we identified the
