产品描述 | Octyl-α-ketoglutarate is a stable, cell-permeable form of α-ketoglutarate, a substrate of prolyl hydroxylases (PHD) [1][2]. The high turnover of HIFα is initiated by prolyl hydroxylases (PHD), which hydroxylate proline residues on the oxygen-dependent degradation (ODD) domain of HIFα, facilitating ubiquitination and degradation. To catalyze proline hydroxylation, PHDs convert molecular oxygen and α-ketoglutarate to carbon dioxide and succinate [2]. Loss of IDH1 activity would reduce cellular levels of α-KG [3]. Octyl-α-ketoglutarate is a cell-permeating α-ketoglutarate derivative, which built up rapidly and preferentially in cells with a dysfunctional TCA cycle. Octyl-α-ketoglutarate increased intracellular levels of freeα-ketoglutaric acid by approximately fourfold. In HEK293-derived cell lines expressing both a GFP-ODD fusion protein and HA-tagged pVHL, Octyl-α-ketoglutarate reactivated PHD activity inhibited by succinate or fumarate. Octyl-α-ketoglutarate restored hydroxylation and targeted HIF1 for ubiquitylation and proteasomally mediated degradation [2]. Octyl-α-ketoglutarate inhibited the HIF-1α induction caused by IDH1 knockdown in HeLa cells or overexpression of IDH1R132H mutant in U-87MG cells, suggesting a reduction in IDH1 activity caused a reduction in α-KG levels that in turn led to stabilization of HIF-1α [3].
