Synthesis and antituberculosis activity of several steroids from 3αacetoxy-5βpregn-16-En-20-one
Sikharulidze Nadaraia Kakhabrishvili
The semicarbazone and isonicotinoylhydrazone of 5βpregn-2-en-20-one, which was prepared from 3βacetoxy-5βpregn-16-en-20-one, were synthesized for the first time. The antituberculosis activity of these and semicarbazones and isonicotinoylhydrazones of saturated, unsaturated, and adamantane-modified ketosteroids synthesized by us earlier was studied in vitro experiments.
UNUSUAL HIGH REACTIVITIES OF Δ5 STEROIDS IN PALLADIUM CATALYZED HYDROGENATION
Nishimura, Shigeo Takahashi, Izumi Shiota, Michio Ishige, Masayoshi
Hydrogenation of a mixture of 3β-hydroxyandrost-5-en-17-one or cholesterol with α-pinene has revealed that the Δ5 steroids are more reactive than α-pinene over palladium while α-pinene is much more reactive than the Δ5 steroids with other platinum metals.
