  Development of Inhibitors of the PAS-B Domain of the HIF-2α Transcription Factor

  摘要：

  Hypoxia inducible factors (HIFs) are heterodimeric transcription factors induced in a variety of pathophysiological settings, including cancer. We describe the first detailed structure-activity relationship study of small molecules designed to inhibit HIF-2 alpha-ARNT heterodimerization by binding an internal cavity of the HIF-2 alpha PAS-B domain. Through a series of biophysical characterizations of inhibitor-protein interactions (NMR and X-ray crystallography), we have established the structural requirements for artificial inhibitors of the HIF-2 alpha-ARNT PAS-B interaction. These results may serve as a foundation for discovering therapeutic agents that function by a novel mode of action.

  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.

  提供了一种抑制HIF-2α与HIF1β（ARNT）异源二聚化的方法，包括将某些小分子结合到HIF-2α PAS-B结构域的空腔中，但不结合到HIF1α，从而抑制HIF-2α与HIF1β（ARNT）的异源二聚化，但不抑制HIF1α与HIF1β（ARNT）的异源二聚化。这些特定的小分子也被同义地称为HIF2-HDI和HIF2α异源二聚化抑制剂，也被简称为某些小分子。
