    Direct preparation of 14β-hydroxy steroids from 14α-H compounds is described; a 15β-hydroxy-14α-H compound is also obtained. Grignard reagents react with 14β-hydroxy-androstan-17-one in the “normal way”, giving a 17β-side chain, but surprisingly organolithium reagents give the unexpected 17α-side chain.

  • Selective inhibition of the cellular sodium pump by emicymarin and 14ß anhydroxy bufadienolides

    Partial inhibition of the sodium pump (Na/K-ATP-ase) by a circulating inhibitor is known to occur in humans. The objectives of this study were to determine the effects of novel bufadienolides lacking an oxygen at C14 on sodium pumps in human erythrocytes and leucocytes, dog kidney and pig brain and to document the importance of the stereochemistry at C17 on the ability to inhibit these sodium pumps. 14 alpha bufadienolides were weak inhibitors of all preparations studied. 3 beta-OH,5 beta,14 beta bufadienolide produced near-total inhibition of dog kidney and pig brain Na/K-ATP-ase. Over the same concentration range, it maximally inhibited the sodium pump of erythrocytes by 70% and leucocytes by 47%. The inhibition profile induced in the leucocyte sodium pump deviated significantly from the simple sigmoidal relationship present in the other preparations over the 3 x 10(-5) to 1 x 10(-7) mol/1 concentration range. Allo-emicymarin (17 alpha) was confirmed to be a weak inhibitor of the sodium pump/ATP-ase compared with emicymarin (17 beta) but both were weaker inhibitors of the leucocyte sodium pump than that of the other preparations. Molecules with the C14 in the beta configuration are more efficacious than in the a configuration. In the case of emicymarin, the attachment of the furone at C17 in the a configuration results in substantially weaker inhibitory activity than in the beta configuration, seen in most cardenolides and bufadienolides. Unlike ouabain and bufalin that show no specificity of action in these preparations, 3 beta-OH,5 beta,14 beta bufadienolide selectively inhibits the activity of at least one low-prevalence subset of the leucocyte Na/K-ATP-ase.
