摘要:
A remedy for endometriosis comprising, as an active ingredient, 14.alpha.-hydroxy-4-androstene-3,6,17-trione or an ester derivative thereof, can effectively treat endometriosis by the strong aromatase-inhibitory activity without giving serious side effects.
摘要:
Antibiotics RK-1061s having a novel chemical structure and a method of production thereof.They have a structural formula represented by general formula(I) wherein A represents R1 or R1CH(OR2)CH2. R2 represents 3-methylglutaric acid residue and R3 represents a sulfate group or a hydrogen atom. The process comprises culturing a ray fungus belonging to the genus Streptomyces and isolating RK-1061s from the culture. Streptomyces sp. SN-1061Ms (FERM BP-5800) is capable of stably producing RK-1061 at a high productivity.
摘要:
A process for the preparation in high yield of 14.alpha.-hydroxy-4-androstene-3,6,17-trione which has an aromatase inhibition activity and is useful as an antitumor agent, in which the 6.beta.-hydroxyl group of 6.beta., 14.alpha.-dihydroxy-4-androstene-3,17-dione is selectively oxidized with the aid of visible light energy.
