2-Oxoglutarate analogue inhibitors of hif prolyl hydroxylase
Abstract
Hydroxylation of hypoxia-inducible factor, a nuclear transcription factor, is catalysed by iron and 2-oxoglutarate dependent hydroxylases. Various analogues of the 2-oxoglutarate cosubstrate were synthesised and shown to inhibit the activity of human hypoxia-inducible factor-1alpha prolyl hydroxylases in cell-free extracts.

R-2HG weakly inhibited PHD2 and BBOX1, with IC50 values of approximately 7 mM and 13 mM, respectively.
“By contrast, inhibition of PHD2 and BBOX1 by R-2HG was weak, with IC 50 values of approximately 7 and 13 mM, respectively, consistent with previous work with the PHDs (Mole et al, 2003).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
