Ethyl2-acetylamino-7-hydroxy-4-pyridin-3-yl-4H-chromene-3-carboxylate (HFI-419), the benzopyran-based inhibitor of insulin-regulated aminopeptidase (IRAP), has previously been shown to improve spatial working and recognition memory in rodents. However, the mechanism of its cognitive-enhancing effect remains unknown. There is a close correlation between dendritic spine density
