Pregnenolone acetate Chemical Properties,Uses,Production

Chemical Properties

white to light yellow crystalline powder or Crystallized (methanol).

Uses

Pregnenolone acetate is an intermediate in the synthesis of progesterone. It is uses as a glucocorticoid and as a skin-conditioning and skin anti-aging agent. It acts as a signaling-specific inhibitor of cannabinoid CB1 receptor, inhibits the effects of tetrahydrocannabinol (THC) that are mediated by the CB1 receptors. It has also been shown to stimulate locomotor activity and neuronal function in rats.

Preparation

Pregnenolone acetate can be prepared by catalytic hydrogenation (16-position double bond) of 16-Dehydropregnenolone acetate.

Definition

Pregnenolone acetate is a steroid ester. It is a pregnenolone derivative, a steroid hormone involved in the steroidogenesis of progesterone, mineralocorticoids, glucocorticoids, androgens, and estrogens.
