SB-269970 hydrochloride has been used to study the effect of different endotype combination on the activity of the 5-hydroxytryptamine receptor of tall fescue alkaloids. It has also been used to inhibit dopamine receptor signaling, in order to study its role in early hemocyte activation.
SB-269970 was used to study the role of 5-HT7 receptors in serotonin-induced hypothermia in rodents.6

Biochem/physiol Actions

SB-269970 is an anti-psychotic agent that shows high affinity for 5-HT7 receptors. It may be effective in treating cognitive disabilities and schizophrenia-like deficits.4 SB-269970 desensitizes and decreases the excitatory effects of 5-HT7 receptors in rat hippocampus.5
Selective 5-HT7 serotonin receptor antagonist.

Binding of the 5-HT(7) receptor antagonist radioligand [(3)H]-SB-269970 to human 5-HT(7(a)) receptors expressed in HEK293 cell membranes (h5-HT(7(a))/293) and to guinea-pig cerebral cortex membranes, was characterized and compared with [(3)H]-5-CT binding. [(3)H]-SB-269970 (1 nM) showed full association with h5-HT(7(a))/293 membranes...
