Prebediolone acetate (brand names Acetoxanon, Acetoxy-Prenolon, Artisone, Artivis, Pregnartrone, Sterosone), also known as 21-hydroxypregnenolone 21-acetate or 21-acetoxypregnenolone (A.O.P.), as well as 3β,21-dihydroxypregn-5-en-20-one 21-acetate, is a synthetic pregnane steroid which is described as a glucocorticoid and has been used in the treatment of rheumatoid arthritis. It is the C21 acetate ester of prebediolone (21-hydroxypregnenolone), the C21 hydroxylated derivative of pregnenolone. Prebediolone acetate has been known since at least 1950. The compound is also an intermediate in a synthesis of deoxycorticosterone acetate (21-acetoxyprogesterone).

Artisone is a steroid of the 21-carbon type. It is 5-pregnene 3 beta, 21-dial-20-one 21 acetate.4 It is also known as 21-acetoxy-pregnenolone, acetoxanon, prebediolone acetate. It is an intermediate product in the synthesis of desoxycorticosterone acetate and is prepared by reacting 5,6-pregnene-3-ol-20-one with bromine and chloroform and treating the obtained oily bromide with potassium I acetate in alcohol.
