Isoform-Selective and Stereoselective Inhibition of Hypoxia Inducible Factor-2
摘要:
Hypoxia inducible factor (HIF) transcription factors reside at the center of signaling pathways used by mammalian cells to sense and respond to low oxygen levels. While essential to maintain oxygen homeostasis, misregulation of HIF protein activity correlates with tumor development and metastasis. To provide artificial routes to target misregulated HIF activity, we identified small molecule antagonists of the HIF-2 transcription factor that bind an internal cavity within the C-terminal PAS domain of the HIF-2 alpha subunit. Here we describe a new class of chiral small molecule ligands that provide the highest affinity binding, the most effective, isoform-selective inhibition of HIP-2 in cells, and trigger the largest protein conformation changes reported to date. The current results further illuminate the molecular mechanism of HIF-2 antagonism and suggest additional routes to develop higher affinity and potency HIF-2 antagonists.

Provided is a method of inhibiting heterodimerization of HIF-2α to HIF1β (ARNT) comprising binding certain small molecules to the HIF-2α PAS-B domain cavity but not to HIF1α and inhibiting HIF-2α heterodimerization to HIF1β (ARNT) but not inhibiting HIF1α heterodimerization to HIF1β (ARNT). Those certain small molecules are also referenced synonymously as HIF2-HDI and HIF2α heterodimerization inhibitors and also simply as certain small molecules.
