Synthesis of 24-heteroatom-substituted cholestanols
Journal of Lipid Research, 1988 Short syntheses of 24-thia-5 alpha,20 xi-cholestan-3 beta-ol, 24-methyl-24-aza-5 alpha,20 xi-cholestan-3 beta-ol, and 24-nor-5 alpha,20 xi-cholan-3 beta-ol from 3 beta-hydroxy-5 alpha-pregnan-20-one are described. The products and synthetic intermediates

7α-Hydroxylation of cholestanol by rat liver microsomes
Journal of Lipid Research, 1968 In a study of the mechanism whereby 5α-bile acids are formed from cholestanol, the 7α-hydroxylation of cholestanol was investigated in rat liver preparations in vitro. It was found that in the presence of NADPH and oxygen, rat liver microsomes catalyzed the 7α-hydroxylation of cholestanol to the same extent as that of cholesterol.The rate of the ...

Synthesis of conjugated cholesterol and cholestanols.
Chemical and Pharmaceutical Bulletin, 1979 The glucuronides, sulfates, glucosides and N-acetylglucosaminides of cholesterol and epimeric 5α-cholestan-3-ols have been synthesized. The formation of a β-glucoside linkage was readily achieved by means of the Koenigs-Knorr reaction with the corresponding α-acetohalosugar, employing cadmium carbonate as a catalyst.

Relation of sterol structure to utilization in pleuropneumonia-like organisms
Journal of Lipid Research, 1964 Six sterols, Δ5-cholesten-3Β-ol (cholesterol), Δ5-cholesten-3α-ol, cholestan-3Β-ol, cholestan-3α-ol, coprostan-3Β-ol, and coprostan-3α-ol, selected to represent variations in the configuration of the A and B rings and of the 3-hydroxyl group, were tested

Crystal structure of cholestanyl caprylate and binary phase behavior with cholesteryl caprylate.
Journal of Lipid Research, 1991 The crystal structure of cholestanyl n-octanoate (caprylate) (C35H62O2) is monoclinic with space group A2 and cell dimensions a = 10.103(7), b = 7.646(7), c = 87.63(7) A, beta = 90.51(6) degrees; Z = 8 [two molecules (A, B) in asymmetric unit], V = 6769 ...

Ypsiyunnosides A–E, Five New Cholestanol Glycosides from Ypsilandra yunnanensis [PDF]
Natural Products and Bioprospecting, 2016 Phytochemical investigation on the whole plants of Ypsilandra yunnanensis was carried out for the first time and led to the isolation of five new cholestanol glycosides, ypsiyunnosides A-E (1-5), and one known analogue. Their structures were determined mainly by detailed spectroscopic analysis, including extensive 1D and 2D NMR, MS and UV, as well as ...
