Common Name(1r,3as,3br,7s,9ar,9bs,11as)-1-[(1s)-1-hydroxyethyl]-9a,11a-dimethyl-2h,3h,3ah,3bh,4h,6h,7h,8h,9h,9bh,10h,11h-cyclopenta[a]phenanthrene-1,7-diol
DescriptionPregn-5-ene-3beta,17alpha,20alpha-triol, also known as pregn-5-ene-3β,17α,20α-triol, belongs to the class of organic compounds known as gluco/mineralocorticoids, progestogins and derivatives. These are steroids with a structure based on a hydroxylated prostane moiety. Thus, pregn-5-ene-3beta,17alpha,20alpha-triol is considered to be a steroid. (1r,3as,3br,7s,9ar,9bs,11as)-1-[(1s)-1-hydroxyethyl]-9a,11a-dimethyl-2h,3h,3ah,3bh,4h,6h,7h,8h,9h,9bh,10h,11h-cyclopenta[a]phenanthrene-1,7-diol is found in Periploca sepium. (1r,3as,3br,7s,9ar,9bs,11as)-1-[(1s)-1-hydroxyethyl]-9a,11a-dimethyl-2h,3h,3ah,3bh,4h,6h,7h,8h,9h,9bh,10h,11h-cyclopenta[a]phenanthrene-1,7-diol was first documented in 2010 (PMID: 20941765). Based on a literature review very few articles have been published on Pregn-5-ene-3beta,17alpha,20alpha-triol.
