SB-269970

SB-269970 is a drug and research chemical developed by GlaxoSmithKline used in scientific studies. It is believed to act as a selective 5-HT₇ receptor antagonist (EC₅₀ = 1.25 nM) (or possibly inverse agonist). A subsequent study in guinea pig at a concentration of 10 μM showed that it also blocks the α₂-adrenergic receptor.^[1][2][3] The large difference in test concentrations however confirms the selectivity of SB-269970 for the 5-HT₇ receptor.

SB-269970 is used to study the 5-HT₇ receptors which are thought to be involved in the function of several areas of the brain such as the hippocampus and thalamus,^[4] and regulation of dopamine release in the ventral tegmental area.^[5] Possible therapeutic uses for SB-269970 and other 5-HT₇ antagonists include the treatment of anxiety and depression,^[6][7] and nootropic effects have also been noted in animal studies.^[8][9]
