چکیده
The title steroid, C(23)H(35)ClO(4), is a pregnane derivative prepared by ring opening of the corresponding 5α,6α-ep-oxy steroid with BiCl(3). There are two symmetry-independent mol-ecules in the asymmetric unit that show no significant differences concerning bond lengths and angles. The conformation of the six-membered rings in both mol-ecules is close to a chair form, while the five-membered ring adopts an envelope conformation. All rings in both mol-ecules are trans-fused. The mol-ecules are held together by an extensive O-H⋯O hydrogen-bonding network.

متن کاملA sensitive and specific LC-MS/MS method for rapid diagnosis of Niemann-Pick C1 disease from human plasma.
Niemann-Pick type C1 (NPC1) disease is a rare, progressively fatal neurodegenerative disease for which there are no FDA-approved therapies. A major barrier to developing new therapies for this disorder has been the lack of a sensitive and noninvasive diagnostic test. Recently, we demonstrated that two cholesterol oxidation products, specifically cholestane-3β,5α,6β-triol (3β,5α,6β-triol) and 7-...
