Short description: Chemical compound

GSK-189,254 is a potent and selective H₃ histamine receptor inverse agonist developed by GlaxoSmithKline. It has subnanomolar affinity for the H₃ receptor (K_i = 0.2nM) and selectivity of over 10,000x for H₃ over other histamine receptor subtypes.^[1] Animal studies have shown it to possess not only stimulant and nootropic effects,^[2] but also analgesic action suggesting a role for H₃ receptors in pain processing in the spinal cord.^[3] GSK-189,254 and several other related drugs are currently being investigated as a treatment for Alzheimer's disease and other forms of dementia,^[4] as well as possible use in the treatment of conditions such as narcolepsy,^[5] or neuropathic pain which do not respond well to conventional analgesic drugs.^[6]
