Sibopirdine (EXP921) is a cognition enhancing agent structurally related to linopirdine that was in preclinical development with Bristol-Myers Squibb in the USA as a treatment of Alzheimer's disease. EXP921 was a potential drug candidate for the improvement of cognitive performance in patients with Alzheimer's-type dementia. It has been shown to improve cognitive performance in rodent and primate models of learning and memory. EXP921 was observed to increase the depolarization induced release of acetylcholine, dopamine, and, to a lesser extent, serotonin using slices from the rat cerebral cortex, hippocampus, and caudate nucleus.
