21-Hydroxy-5beta-pregnane-3,11,20-trione
IUPAC 名称
(1S,2S,7R,10S,11S,15S)-14-(2-hydroxyacetyl)-2,15-dimethyltetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadecane-5,17-dione
描述
21-Hydroxy-5beta-pregnane-3,11,20-trione is an intermediate in C21-Steroid hormone metabolism. 21-Hydroxy-5beta-pregnane-3,11,20-trione is the
second to last step in the synthesis of 3alpha,20alpha,21-Trihydroxy-5beta-pregnane-11-one and is converted from 11-Dehydrocorticosterone via the enzyme 3-oxo-5beta-steroid 4-dehydrogenase (EC 1.3.99.6). It is then converted to 3alpha,21-Dihydroxy-5beta-pregnane-11,20-dione via the enzyme 3-alpha-hydroxysteroid dehydrogenase (EC 1.1.1.50). [HMDB]
