19-Oxo-deoxycorticosterone
IUPAC 名称
(2S,14S,15S)-14-(2-hydroxyacetyl)-15-methyl-5-oxotetracyclo[8.7.0.0²,⁷.0¹¹,¹⁵]heptadec-6-ene-2-carbaldehyde
描述
19-oxo-deoxycorticosterone (19-oxo-DOC) is a steroid recently isolated from the rat adrenal gland.19-Oxo-Deoxycorticosterone Binds to the Renal Mineralocorticoid Receptor and Produces Sodium Retention but Not Potassium Excretion.19-oxo-DOC both binds to type I renal mineralocor-ticoid receptors and produces the expected antinatriuretic effect of maximal doses of mineralocorticoids. This lack of a kaliuretic effect suggests that either 1) the kaliuretic effect of steroids such as aldosterone is mediated by a binding site other than the type I receptors, or 2) that potassium secretion mediated by aldoster-one-type I receptor interactions in discrete nephron target segments can be influenced by a steroid-sensitive potassium-recycling system in a more distal nephron site
19-hydroxydeoxycorticosterone (19,21-dihydroxy-4-pregnen-3,20-dione), 19-oxo-deoxycorticosterone (21-hydroxy-4-pregnen-3,19,20-trione), and 19-oic-deoxycorticosterone (19-oic-21-hydroxy-4-pregnen-3,20-dione)are formed from precursor deoxycorticosterone by adrenal glands obtained from intact rats and from rats undergoing adrenal regeneration.rat adrenals have the enzymes required to convert deoxycorticosterone to 19-hydroxydeoxycorticosterone, 19-oxo-deoxycorticosterone, and 19-oic-deoxycorticosterone; however, rat adrenals do not convert deoxycorticosterone or any of the oxygenated metabolites to 19-nor-deoxycorticosterone (21-hydroxy-19-nor-4-pregnen-3,20-dione). It is possible, however, that 19-nor-deoxycorticosterone is formed at peripheral sites from the oxygenated deoxycorticosterone precursors [HMDB]
