<unk>  also known as 5-pregnenolone or as pregn-5-en-3β-ol-20-one, is a naturally occurring pregnane steroid and a derivative of cholesterol. Related steroids include<unk> sulfate, 3β-dihydroprogesterone (4-pregnenolone), progesterone, allopregnanolone, and<unk> . Derivatives A few synthetic ester derivatives of<unk> exist. These include<unk> acetate (Antofin, Previsone, Pregno-Pan) and<unk> succinate (Panzalone, Formula 405). Prebediolone acetate (Acetoxanon, Acetoxy-Prenolon, Artisone, Artivis, Pregnartrone, Sterosone), the 21-acetate ester of 21-hydroxypregnenolone, also exists. These esters are all described as glucocorticoids similarly to<unk>  The 3β-methyl ether of<unk>  3β-methoxypregnenolone (MAP-4343), retains similar activity to<unk> in regard to interaction with MAP2, and is under development for potential clinical use for indications such as the treatment of brain and spinal cord injury and depressive disorders.
