Patent number: 7989630Abstract: 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.Type: GrantFiled: April 30, 2008Date of Patent: August 2, 2011Assignee: National Institutes of Health Represented by the Secretary of the Department of Health and Human Services, National Institutes of HealthInventors: Victor W. Pike, Robert B. Innis, Sami S. Zoghbi, Neva Lazarova

Publication number: 20030130336Abstract: This invention relates to a method of predicting the activity of a CNS drug on striatal dopamine transporter populations. The method uses SPECT brain imaging to predict the activity of antidepressants or anxiolytic agents on striatal dopamine transporter populations. The method uses the increase in dopamine transporter populations as a marker for predicting sexual dysfunction side effects, as well as to determine proper dosing for antidepressants or anxiolytics agents in order to avoid the sexual dysfunction side effects.Type: ApplicationFiled: December 31, 2002Publication date: July 10, 2003Applicant: Pfizer Inc.Inventors: Peter J. Snyder, Robert B. Innis, John P. Seibyl, Akira Kugaya, Stephen A. Williams

Patent number: 6537522Abstract: Iodinated neuroprobes for mapping monoamine reuptake sites in the brain, and particularly iodinated neuroprobes that can also serve as radiotracers for use in single-photon emission computed tomography (SPECT) and positron emission tomography (PET) for imaging of such reuptake sites, are disclosed. Precursors of radiolabeled iodinated neuroprobes, both with and without a radiotracer atom, and kits for preparing the radiolabeled iodinated neuroprobes are also disclosed.Type: GrantFiled: May 12, 1998Date of Patent: March 25, 2003Assignee: Amersham PLCInventors: John L. Neumeyer, Richard A. Milius, Robert B. Innis, Gilles Tamagnan, Shaoyin Wang
