Mercapto steroids in protection against mercury and lead poisoning
Blickenstaff,Cox,Foster,Roberts,Steinrauf
, p. 556 - 558 (1980)
When thiocholesterol is administered as liposomes, it provides significant protection against methylmercuric chloride in mice when given in three intraperitoneal injections, 0.5 hr before and 2 and 8 hr after the methylmercuric chloride. Thiositosterol, 5
Solvolysis of sterol tosylates in aqueous dimethylformamide
Kovganko,Survilo
, p. 324 - 327 (2007/10/03)
It has been established that the heating of the sterol tosylates (1a - c) in aqueous dimethylformamide in the presence of sodium acetate leads to the formation of the 3α,5-cyclo-6β-alcohols (2), the sterols (3), the 3,5-dienes (4), and the sterol formates (5).
SYNTHESIS OF THE ANALOGS OF BRASSINOSTEROIDS BASED ON β-SITOSTEROL
Kovganko, N. V.,Kashkan, Zh. N.
, p. 2205 - 2211 (2007/10/02)
The synthesis of 22,23-dideoxy-28-homobrassinolide and its related brassinosteroid analogs was realized from β-sitosterol.
Synthesis of Biological Markers in Fossil Fuels. 4. C27, C28, and C29 13β,17α(H)-Diasteranes
Bauer, Phillip E.,Nelson, David A.,Watt, David S.,Reibenspies, Joseph H.,Anderson, Oren P.,et al.
, p. 5460 - 5464 (2007/10/02)
The rearrangement of 5-cholestene to (20ξ)-13(17)-diacholestenes, separation of C-20 epimers, and further reduction provided an unambiguous synthesis of the biomarkers (20R)- and (20S)-13β,17α(H)-diacholestanes.Repetition of this sequence using (24R)-5-campestene or (24R)-5-stigmastene provided the analogous C28 and C29 diasteranes.
Synthesis of Analogues of Brassinolide and Castasterone
Mitra, R. B.,Hazra, B. G.,Kapoor, V. M.
, p. 106 - 109 (2007/10/02)
Syntheses of 2α,3α,22R,23R-tetrahydroxy-24S-ethyl-B-homo-7-oxa-5α-cholestan-6-one (5) and 2α,3α-dihydroxy-24S-ethyl-B-homo-7-oxa-5α-cholestan-6-one (7) are described starting from stigmasterol and β-sitosterol respectively.
