(3α,9β,10α,13α,14β,17α,20S,22E)-Ergosta-5,7,22-trien-3-ol. A method for preparing the same by drying a fruiting body of Cordyceps militaris, grinding the fruiting body to yield ultrafine powders; boiling and extracting the ultrafine powders, centrifuging and collecting a precipitate. A method for treating a tumor by administering to a patient in need of treating a tumor (3α,9β,10α,13α,14β,17α,20S,22E)-ergosta-5,7,22-trien-3-ol.
Abstract:
The invention relates to a method of preparing a 9beta,10alpha-5,7-diene steroid by irradiating the corresponding 9alpha,10beta-5,7-diene steroid with filtered ultraviolet light from an indium lamp.
Abstract:
The novel intermediates and processes of this invention provide a new synthetic route for the preparation of pharmaceutically valuable 19-norsteroids. Further, the intermediates and processes of the invention provide a novel route for the preparation of pharmaceutically valuable estrones. The present invention provides a facile total synthesis of 19.beta.-alkyl-C/D-trans-steroidal materials. This desirable result is obtained via a unique asymmetric induction followed by subsequent stereospecific reaction steps. As a precursor to the steroidal Ring A, a 3,5-disubstituted-4-isoxazolylmethylene group is employed in this synthesis.
Abstract:
1,3-Dihydroxy-8.alpha.-estratrienes of the formula ##SPC1##Wherein R is lower-alkyl and --A--B is ##SPC2##Wherein R' is a saturated or unsaturated hydrocarbon group and R" is lower-alkyl, aralkyl or phenyl, and the esters and ethers thereof, possess strong vaginotropic but only weak utertropic activity and are useful in the treatment of estrogenic deficiency conditions where uteral effects are not desired.
