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.
