Steroid-hindered 17β-tertiary alcohol: Characterization of dehydrated compounds
摘要:
Five dehydrated compounds obtained from a tert-butyldimethylsilychloride/imidazole or an aqueous hydrochloric acid treatment of 17 alpha-butyl-3-O-methyl estradiol in refluxing solvent were purified and characterized. Three compounds were obtained from a direct vicinal proton elimination, the two others from a vicinal elimination after migration of methyl-18. Depending on the treatment, the proportions of dehydrated compounds are different. In addition, a general profile of experimental conditions providing a similar mixture of dehydrated compounds was also established for this steroid-hindered 17 beta-tertiary alcohol.

[EN] The invention relates to a method of altering hypothalamic function in an individual. The method comprises nasally administering a human vomeropherin, e.g. a 19-nor cholane steroid, or a pharmaceutical composition containing a vomeropherin, such that the vomeropherin binds to a specific neuroepithelial receptor. The steroid or steriods is/are preferably administered in the form of a pharmaceutical composition containing one or more pharmaceutically acceptable carriers. Other embodiments of the invention include pharmaceutical compositions containing the steroids. [FR] L'invention concerne une méthode pour modifier la fonction hypothalamique chez un sujet. Cette méthode consiste à administrer par les voies nasales une vomérophérine humaine, par exemple un stéroïde de 19-nor cholane, ou bien une composition pharmaceutique contenant une vomérophérine, de sorte que la vomérophérine se fixe à un récepteur neuroépithélial spécifique. Le ou les stéroïdes est/sont de préférence administrés sous la forme d'une composition pharmaceutique contenant un ou plusieurs excipients pharmaceutiquement acceptables. D'autres formes d'exécution de l'invention concernent des compositions pharmaceutiques contenant les stéroïdes.
