SB-271046 is one of the first selective 5-HT6 receptor antagonists to be discovered. SB-271046 is a potent, selective and orally active 5-HT6 receptor antagonist with a pKi value of 8.9. This compound provides a useful tool for further elucidating the physiological function of 5-HT6 receptors in vivo. SB-271046 was found to increase levels of the excitatory amino acid neurotransmitters glutamate and aspartate, as well as dopamine and noradrenaline in the frontal cortex and hippocampus of rats, and 5-HT6 antagonists have been shown to produce nootropic effects in a variety of animal studies. Suggested applications of SB-271046 included treatment of schizophrenia and other psychiatric disorders. A phase I clinical development of SB-271046 by GlaxoSmithKline (GSK) was discontinued due to a poor BBB permeability.
