5a-Tetrahydrocortisol
IUPAC 名称
2-hydroxy-1-[(1S,2S,5R,7S,10S,11S,14R,15S,17S)-5,14,17-trihydroxy-2,15-dimethyltetracyclo[8.7.0.0^{2,7}.0^{11,15}]heptadecan-14-yl]ethan-1-one
描述
5a-Tetrahydrocortisol is a normal human metabolite. However its increased ratio (5alpha-Tetrahydrocortisol + Tetrahydrocortisol) over Tetrahydrocortisone in urine is the biochemical marker for the syndrome of apparent mineralocorticoid excess (AME). AME is a heritable form of hypertension due to an inborn error of cortisol metabolism and is characterized by hypokalemia and low renin levels despite subnormal or normal levels of aldosterone and other known mineralocorticoids. The syndrome is attributable to congenital deficiency of the enzyme 11 beta-hydroxydehydrogenase (11 beta-HSD), which converts cortisol to biologically inactive cortisone. This results in a prolonged half-life of Cortisol, which acts at the kidney level as a potent mineralocorticoid. (PMID: 8732999) [HMDB]
