Scientific background

Serotonin (5-hydroxytryptamine, 5-HT1) is an important neurotransmitter in the central nervous system (CNS) that exerts its neuronal activity via 5-HT receptors.

5-HT receptors are subdivided into seven families termed 5-HT1 through 5-HT7.1  The 5-HT receptor families belong to the G-protein coupled receptor superfamily with the exception of 5-HT3 receptor class which belongs to the ligand-gated ion channels.2

The 5-HT1 receptor class comprises of five different receptors (5-HT1A, 5-HT1B, 5-HT1D, 5-HT1E and 5-HT1F) which share 41-63% overall sequence identity and couple preferentially to Gi/Go to inhibit cAMP formation.2

The 5-HT1A receptor is the most widespread of all the 5-HT receptors. In the CNS, 5-HT1A receptors exist in the cerebral cortex, hippocampus, septum, amygdala and raphe nucelus in high densities, and was also demonstrated in a variety of tissues from various species.2,3 

Activation of 5-HT1A receptor decreases blood pressure and heart rate, and is involved in learning, memory, relieving anxiety and depression.1,4
