GTS-21 (DMXBA) is a derivative of the natural product anabaseine that acts as a partial agonist at neural nicotinic acetylcholine receptors. It binds to both the α4β2 and α7 subtypes, but activates only the α7 to any significant extent.[1][2]

Both GTS-21 itself and its demethylated active metabolite 4-OH-GTS-21[3] display nootropic[4] and neuroprotective effects,[5][6][7][8] and GTS-21 is being investigated for the treatment of Alzheimer's disease,[9] nicotine dependence,[10] and, most significantly, for schizophrenia.[11][12][13][14][15]

The laboratory name GTS-21 means that it is the 21st chemical compound created by Gainesville (University of Florida in Gainesville) and Tokushima (Taiho Pharmaceutical) Scientists.[16] DMXB-A – 3-2,4-dimethoxybenzylidene anabaseine.
