Reduction and oxidation of 7 - oxysterols by murine 11 beta HSD1 proceeded more slowly and substrate affinity was lower than for glucocorticoids . in vitro 7 beta OHC was a competitive inhibitor of oxidation of corticosterone ( Ki = 0 . 9 mu M ) , whereas 7KC only weakly inhibited reduction of 11 - dehydrocorticosterone .
