Abstract: Provided herein are hypoxia inducible factor 2-alpha (HIF-2α)-specific radioactive tracers, methods of use thereof, and methods of synthesis thereof. Specifically, provided herein are HIF-2α-specific radioactive tracers comprising an HIF-2α-specific agent developed as a therapeutic inhibitor and a positron emitting radioactive label. Embodiments provide methods of detecting an HIF-2α-expressing tumor, detecting an HIF-2α inhibitor resistant tumor, evaluating a change in HIF-2α expression in response to an anti-cancer treatment, detecting acquisition of HIF-2α inhibitor resistance, evaluating efficacy of an HIF-2α depletion therapy, or detecting or monitoring an ischemic area in a subject. Also provided are methods of synthesizing an HIF-2α-specific radioactive tracer.

Abstract: The present disclosure relates to polymers which contain a hydrophobic and hydrophilic segment which is sensitive to pH as well as a metal chelating group. In some aspects, the metal chelating group is chelated to a metal ion capable of positron emission. In some aspects, the polymers form a micelle which is sensitive to pH and results in a change in fluorescence based upon the particular pH. In some aspects, the disclosure also provides methods of using the polymers for the imaging of cellular or extracellular environment or delivering a drug.
