Patent CA-2447780-A1 (CA)
Inventor: JI GUEIJUN
IPC: C07J11/00
Filed: 2002-05-22
Abstract: Steroids containing a cyclohexene moiety are efficiently oxidized to the corresponding .alpha., .beta.-unsaturated ketone using copper iodide and t- butyl hydroperoxide. A steroid compound containing the .alpha., .beta.- unsaturated ketone structure is efficiently converted to the corresponding vicinal diol using a hydroborating reagent followed by oxidative workup, e.g ., borane followed by sodium perborate. Benzoyl and substituted benzoyls are superior protecting groups for hydroxyl groups present in the compounds.</SD OAB>

Abstract: Il s'est avéré que, en produisant une molécule d'ARN à tige-boucle à partir d'un ADN codant cette molécule d'ARN au moyen d'un promoteur d'ARNt, la molécule d'ARN peut être transférée efficacement dans le cytoplasme afin d'exercer l'effet ARNi. L'effet ARNi peut également être exercé efficacement par transfert d'une séquence de signaux de transfert du cytoplasme dans un ADN codant une molécule d'ARN à tige-boucle. De plus, l'effet ARNi peut être efficacement exercé par transfert d'un produit de transcription dans le cytoplasme au moyen d'un promoteur de type pol II. Dans ce cas la cytotoxicité peut être réduite par co-expression d'un gène Dicer. En outre, il est possible de construire un ARNds efficace en traitant un ARNds ou une molécule d'ARN à tige-boucle avec une protéine Dicer. L'utilisation de ces systèmes d'expression de molécules d'ARN à tige-boucle permet de construire efficacement des cellules d'extinction dépourvues d'un gène souhaité.
