Synthesis of 3β-hydroxy-5α-cholest-8-en-7-one and 3β-hydroxy-5α-cholest-8-en-11-one: Evaluation as potential hypocholesterolemic agents
摘要:
An efficient procedure for the chemical synthesis of 3 beta-hydroxy-5 alpha-cholest-8-en-7-one and 3 beta-hydroxy-5 alpha-cholest-8-en-11-one is described. These ketosterols have been shown to have possible significant hypocholesterolemic effects when fed to normal rats at a level of 0.15% in a laboratory chow diet. The diets containing the steroids caused significant decreases in food consumption which were associated with decreases in the rate of gain in body weight.
Sterol derivative compounds, structurally related to natural compounds which can be extracted from bull testes and from human follicular fluid, useful for regulating meiosis in oocytes and in male germ cells. Some of these compounds are useful in the treatment of infertility, whereas other compounds are useful as contraceptives.
