19β,28-Epoxy-18α-olean-3β-ol
The title triterpene, C(30)H(50)O(2), is an 18α-oleanane derivative prepared by the Wagner-Meerwein rearrangement of betulin with Bi(OTf)(3).xH(2)O (OTF is trifluoromethanesulfonate). 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 is close to a chair form, wh...
متن کاملFirst Total Synthesis of Ergosta-5,8-dien-3β-ol
The first total synthesis of ergosta-5,8-dien-3β-ol, an uncommon sterol previously isolated from an alga and several microorganisms, has been developed. For the first time, a full set of spectroscopic data of this sterol is presented.
متن کامل2′-Methylpyrazolo[4′,3′:16,17]androst-5-en-3β-ol
In the title compound, C(21)H(30)N(2)O, there are five fused rings. The A and C rings adopt chair conformations, ring B adopts an 8β,9α-half-chair conformation and ring D adopts a 14α-envelope conformation. The pyrazole ring is planar. Inter-molecular O-H⋯N hydrogen bonds [H⋯N = 1.88 (5) Å] help to stabilize the crystal structure. The absolute structure was deduced from those of the starting ma...
متن کاملConversion of Sa-Cholestan-3@-ol to ~‘-5~-Cholesten-3~-ol in Cockroaches*
Detailed studies of the sterol requirement of the carnivorous beetle Dermestes vulpinus (1) which have been carried out in this laboratory have indicated that up to 97% of the normal dietary cholesterol requirement of this insect may be replaced by a number of other sterols. One of the compounds capable of sparing but not completely replacing cholesterol in the diet of these insects is cholesta...
متن کاملAntiinflammatory and Antiphotodamaging Effects of Ergostatrien-3β-ol, Isolated from Antrodia camphorata, on Hairless Mouse Skin.
Ergostatrien-3β-ol (EK100), isolated from the submerged whole broth of Antrodia camphorata, has antidiabetic, hyperlipidemic, and hepatoprotective activities. However, the antiphotodamage activity of EK100 has still not been revealed. Inflammation and collagen degradation contribute to skin photodamage and premature aging. In the present study, in vivo experiments were designed to investigate t...
