Pregnenolone sulfate (PS, PREGS), also known as pregn-5-en-3β-ol-20-one 3β-sulfate, is an endogenous excitatory neurosteroid that is synthesized from pregnenolone.[1][2] It is known to have cognitive and memory-enhancing, antidepressant, anxiogenic, and proconvulsant effects.[2]
Biological activity
Pregnenolone sulfate is a neurosteroid with excitatory effects in the brain, acting as a potent negative allosteric modulator of the GABAA receptor and a weak positive allosteric modulator of the NMDA receptor.[1][2] To a lesser extent, it also acts as a negative allosteric modulator of the AMPA, kainate, and glycine receptors,[3][4] and may interact with the nACh receptors as well.[1] In addition to its effects on ligand-gated ion channels, pregnenolone sulfate is an agonist of the sigma receptor,[2] as well as an activator of the TRPM1 and TRPM3 channels.[1] It may also interact with potassium channels and voltage-gated sodium channels[1] and has been found to inhibit voltage-gated calcium channels.[5]
