Corticosterone (B) and 18-hydroxy-11-deoxycorticosterone (18OHDOC) but not 11-deoxycorticosterone (DOC) displaced cortisol (F) specifically bound to rat adrenal mitochondria. F. competitively inhibited aldosterone formation from B, 18OHB and 18OHDOC but did not inhibit conversions of DOC to B or 18OHDOC. High concentrations of DOC increased its conversion to 18OHDOC rather than B.
皮质酮(B)和18-羟基-11-脱氧皮质酮(18OHDOC),而非11-脱氧皮质酮(DOC),能特异性地取代与大鼠肾上腺线粒体特异性结合的皮质醇(F)。F竞争性抑制由B、18OHB和18OHDOC生成醛固酮,但不抑制DOC向B或18OHDOC的转化。高浓度的DOC会增加其向18OHDOC而非B的转化。
