Pregnenolone-d4 CAS Number

Pregnenolone-d4 is a deuterium-labeled derivative of pregnenolone, an endogenous steroid hormone and neurosteroid precursor. Pregnenolone functions as a signaling-specific inhibitor of cannabinoid CB1 receptors and serves as a key intermediate in the biosynthesis of progestogens, glucocorticoids, mineralocorticoids, and androgens. By modulating CB1 receptor signaling and neurosteroid pathways, pregnenolone influences synaptic plasticity, cognitive function, and cellular responses to cannabinoid activation.
