We have previously shown that human subjects metabolize the 20 beta-epimer of isocortisol (11 beta, 17,20 beta-trihydroxy-3-oxo-pregn-4-en-21-al) to both 20 alpha- and 20 beta-hydroxy steroid end products. In this paper we describe the synthesis of tritium labeled 20 alpha-epimers of isocortisol and isoTHF (3 alpha, 11 beta, 17,20 alpha-tetrahydroxy-5(More)
A method is presented for the chemical synthesis of corticosteroid derivatives containing the 20 alpha, 21-diol and 17 alpha, 20 alpha, 21-triol side chains. The ketol side chains of cortisol, corticosterone, 11-deoxycortisol, and 11-deoxycorticosterone were reduced at C-20 with sodium borohydride in a two-phase system consisting of aqueous calcium chloride(More)
Genetic polymorphisms of IFN regulatory factor 5 (IRF5) are associated with an increased risk of lupus in humans. In this study, we examined the role of IRF5 in the pathogenesis of pristane-induced lupus in mice. The pathological response to pristane in IRF5 2/2 mice shared many features with type I IFN receptor (IFNAR) 2/2 and TLR7 2/2 mice: production of(More)
