The X-ray crystal structure of 3~-benzoyloxy-6a-chloro-5a-cholest-7-ene (IV) was determined by the heavy atom method and ref'med to R ---0.063 (space group P2s, a --11.364, b = 11.089, c --12.232,/~ = 99.43 °, Z ---2). IV was previously shown to be an important intermediate in the acid-catalyzed iso

Oxidized LDL exhibits cytotoxic activity towards endothelial cells, which is thought to be mediated by the products derived also from cholesterol oxidation, mainly involving the B-ring. By LC-PB-EI-MS and El-MS/MS analysis, we have identified 3fl-hydroxy-5~-cholest-6-ene-5-hydroperoxide among the ch
