New evidence for the structure of myxinol.

چکیده
1. Preliminary spectroscopic examination of a second component of hagfish bile salts suggested that it might be 3beta,7alpha,26(27)-trihydroxy-5alpha-cholestane. 2. Impure reduction products of the 3beta,26(27)-dihydroxycholestane-7,16-dione previously made from myxinol disulphate appeared also to have the 5alpha-configuration. 3. Infrared, nuclear-magnetic-resonance and mass-spectrographic as well as optical-rotatory-dispersion measurements on 3beta,26(27)-dihydroxycholestane-7,16-dione showed that it was a 5alpha-compound. 4. Myxinol is thus 3beta,7alpha,16alpha,26(27)-tetrahydroxy-5alpha-cholestane; new nuclear-magnetic-resonance measurements on myxinol tetra-acetate at higher resolution confirm this structure.

Nuclear-magnetic-resonance and mass-spectral study of myxinol tetra-acetate.
Myxinol tetra-acetate was examined by both nuclear-magnetic-resonance and mass-spectral techniques. The results are compared with corresponding data for 5alpha-ranol tetra-acetate and 5alpha-cyprinol tetra-acetate. The structure deduced for myxinol tetra-acetate, 3beta,7alpha,16alpha,27-tetrahydroxy-5beta-cholestane, is in agreement with that simultaneously arrived at by Haslewood (1966).

متن کاملNew Analytic Method for Subgrade Settlement Calculation of the New Cement Fly-ash Grave Pile-slab Structure
At present, reducing subgrade settlement of soft soil foundation is a key problem in high-speed railway construction. Pile-slab structure is a widely-utilized form of foundation structure to reduce the subgrade settlement in China. In order to save the engineering cost for high-speed railway construction in developing countries, the author developed a pile-slab structure and named it as the new...
متن کاملEvidence Based Medicine and Herbal Medicine
Evidence based medicine (EBM) can be found as far back as the 1940s. However, it was in 1972 that the concept first came into play, originated by Professor Archie Cochrane, in his book, Effectiveness & Efficiency: Random Reflections on Health Services. This was the foundation for evidence based research, and in 1992 a facility was funded by the UK government, with the aim of performing r...
