2,4-DPD is a cell permeable, competitive inhibitor of the oxygen-sensing enzyme HIF-α prolyl hydroxylase (HIF-PH) .
Hypoxia-inducible factor (HIF) is a transcription factor with a key role in cellular responses to hypoxia in a variety of organisms. The HIF system plays an important role in angiogenesis, erythropoiesis, energy utilization, glucose/energy metabolism, tumour development, and ischaemic/hypoxic disease. Genetic or pharmacological inactivation of the HIF hydroxylases results in a constitutive activation of the HIF pathway with little or even absent regulation by oxygen remaining. The oxygen-sensing enzyme HIF-α prolyl hydroxylase catalyzes hydroxylation of specific prolyl and asparaginyl residues in the regulatory HIF-α subunits .
Exposure to 2,4-DPD limited prolyl 4-hydroxylase activity in C. elegans., where their esters are hydrolyzed to form competitors of a -ketoglutarate. 2,4-DPD showed dramatic effects among the progeny. When exposed to a high level of 2,4-DPD (2.7 mM), all progeny died regardless of genotype of C. elegans. The dead embryos arrested at the twofold stage .
