Nebracetam is an investigational drug of the racetam family that is a M1 acetylcholine receptor agonist in rats.[1] Based on a human leukemic T cell experiment in 1991, it is believed to act as an agonist for human M1-muscarinic receptors.[2] It is also believed to act as a nootropic, like many other racetam drugs.[3] A chemoenzymatic method of synthesis was reported in 2008.[4] As of 2023, human trials have not yet been conducted.
