The synthesis of (–)-sandaracopimaradiene from androstane derivatives
J. Chem. Soc. C, 1966The conversion of testosterone and 3β-hydroxyandrost-5-en-17-one into the diterpene sandaracopimaradiene is described. 4,4-Dimethyl-5α-androst-14-ene and its 17β-hydroxy-derivative were prepared by acid-catalysed isomerisation of the 5,7-dienes, hydrogenation, and further isomerisation of the resulting 8(14)-olefins.

Androstane and Withanolides fromPhysalis cinerascens
Planta Medica, 2005Two new withanolides, cinerolide and 24,25-dihydrowithanolide S, together with the new androstane, cinedione, and the known withanolides, visconolide, physalactone, withanolide S and 4beta-hydroxywithanolide E were isolated from the EtOAc extract of leaves, flowers and stems of Physalis cinerascens. The structures of these compounds were established by

Substituted androstanes as aromatase inhibitors
Russian Chemical Reviews, 1998The synthesis and structure–activity relationships of inhibitors of steroid aromatase which catalyses the last stage of a multistep biotransformation of cholesterol into estrogens, viz., aromatisation of C19-steroids into C18-phenolic steroids, are discussed.

Androsterone (3alpha-hydroxy-5alpha-androstan-17-one), 5alpha-androstane-3alpha, 17beta-diol and 5alpha-androstane-3beta, 17beta-diol were conjugated at C-16 through sulfur to bovine and human serum albumin. Rabbits injected with these conjugates produced antibodies suitable for radioimmunoassays of these hormone metabolites.
