Radiotracers for Imaging P-glycoprotein Transporter Function
This invention offers technology to help treat certain brain diseases, such as Alzheimer's disease and Parkinson's, and may lead to more effective and personalized treatments. P-glycoprotein transporter (P-gp) acts as a pump at the blood-brain barrier to exclude a wide range of xenobiotics (e.g., toxins, drugs, etc.) from the brain and is also expressed in a tumor in response to exposure to established/prospective chemotherapeutics (a phenomenon known as multidrug resistance; MDR). The instant invention relates to compounds that are avid substrates for P-gp, and their preparation and use as radiotracers for imaging P-gp function in vitro and in vivo.
