Common NamePregnanolone sulfate
DescriptionPregnanolone sulfate (PAS) belongs to the class of organic compounds known as sulfated steroids. These are sterol lipids containing a sulfate group attached to the steroid skeleton. Pregnanolone sulfate is an endogenous steroid that inhibits neuron N-methyl-D-aspartate (NMDA) receptors by inducing desensitization of activated NMDA receptors (PMID: 19474309 ).
