摘要:
Compounds and methods are provided for treating patients suffering from health condition associated with an expression state of a gene such as fertility disorders, cancer, proliferative dis5ases, vascular diseases, wounds requiring therapeutic intervention, inflammation, and pulmonary disorders by administering to said patient a compound capable of modulating egr-1 and/or an egr-1 response element consensus sequence thereby altering the expression state of said gene. Also described are new methods for screening compounds to identify effectors of egr-1 and/or egr-1 consensus sequence elements and methods for treating patients by administering such effectors to modulate egr-1 and/or egr-1 consensus sequences to thereby modify expression of genes associated therewith to in turn treat diseases or other physiological conditions associated with such gene expression.
摘要:
Procédé permettant d'obtenir un rendement élevé d'esters de nitrate solubles dans l'eau ou dans l'acide sans recours à des solvants organiques dans la réaction de nitratation et sans produire des produits ou des produits secondaires instables. Le procédé consiste à nitrater un composé organique à teneur en hydroxy à l'aide d'un agent de nitratation approprié tel que l'acide nitrique en l'absence de solvants organiques dans la réaction de nitratation. On neutralise le mélange réactionnel, ce qui provoque la précipitation ou la séparation des esters de nitrate de la solution de nitrate neutralisée. Ensuite, on récupère l'ester de nitrate et l'on peut en enlever tous les éventuels sels de nitrate dissous par un lavage délicat avec de l'eau ou avec une solution diluée d'halogénure. Selon le procédé, on n'utilise aucun solvant organique dans la réaction de nitratation, et les rendements moyens sont compris entre environ 80 % et environ 95 %.
