Inventors have developed a novel method to enhance the penetrance of multiple GCPII inhibitors which were developed by the inventor and Dr. Pomper at JHU. This method demonstrated improved brain penetrance in rodents. The penetrance of a specific GCPII inhibitor showed significant brain penetrance in non-human primates and inhibited GCPII activity in the brain in rodents.
