ABSTRACT:
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 or prospective chemotherapeutics (a phenomenon known as multidrug resistance). This invention concerns the preparation and use of radiotracers for imaging P-gp function in vitro and in vivo. Radiotracers of the present invention are avid substrates for P-gp and have structures based on N-Desmethyl-loperamide.
