Description

GTS-21 2HCl, also known as DMBX-A, 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. Both GTS-21 itself and its demethylated active metabolite 4-OH-GTS-21 display nootropic and neuroprotective effects, and GTS-21 is being investigated for the treatment of Alzheimer's disease, nicotine dependence, and, most significantly, for schizophrenia.

How to use

In Vitro:

GTS-21 bound to human α4β2 nAChR (Ki=20 nM) 100-fold more potently than to humanα7-nAChR, and is 18- and 2-fold less potent than (-)-nicotine at human α4β2 and a7 nAChR, respectively.

In Vivo:

GTS 21 (4 mg/kg; i.p.; 1, 3, 7, 14 and 21 days) reduces radiation induced histological signs of pulmonary injury.
