Modification of steroid molecules by introducing heterocyclic ring into the core structure of steroids has been utilized as an attractive approach for either cancer prognosis or diagnosis. Several new cholestanoheterocyclic steroids were synthesized, and analytical and spectral data proved the

The effects of cholesterol and cholesterol-derived oxysterols (cholestanone, cholestenone, coprostanone and epicoprostanol) on adipocyte ghost membrane fluidity were studied using a fluorescence depolarization method. The fluorescence anisotropy of the treated membranes was determined using 1,6-diphenyl-1,3,5-hexatriene (DPH) and 1-(4-trimethylammoniumphenyl)-6-phenyl-1,3,5-hexatriene (TMA-DPH). Cholestanone
