Ensaculin (KA-672) is a drug from the coumarin family, which has been researched as a potential treatment for dementia. It acts on a number of receptor systems, being both a weak NMDA antagonist and a 5HT1A agonist.[1][2] Animal studies have shown promising nootropic effects,[3][4] although efficacy in humans has yet to be proven. It was well tolerated in human trials, with the main side effect being orthostatic hypotension (low blood pressure).[5]
