    • The object of the present invention is a novel mandelate salt of a substituted tetracyclic tetrahydrofuran derivative according to Formula (I) the N-oxide forms and the stereochemically isomeric forms thereof, wherein R1 and R2 each independently are hydrogen or C1-6alkyl and R3 and R4 each independently are hydrogen or halogen. In the foregoing definitions C1-6alkyl defines straight and branched saturated hydrocarbon radicals having from 1 to 6 carbon atoms such as, for example, methyl, ethyl, propyl, butyl, 1-methylpropyl, 1,1-dimethylethyl, pentyl or hexyl. The novel mandelate salt is not light-sensitive and is far more stable than the prior art salts at room temperature, enhanced temperature and at relative high humidities and in aqueous media. Also disclosed are pharmaceutical compositions comprising mandelate salts according to the invention, mandelate salts according to the invention for use as a medicine, a process for preparing the mandelate salts according to the invention and the use of the mandelate salts and pharmaceutical compositions comprising mandelate salts according to the invention for the treatment or the prevention of CNS disorders, cardiovascular disorders and gastrointestinal disorders.
    • 本发明的目的是根据式(I)的N-氧化物形式及其立体化学异构形式的取代四环四氢呋喃衍生物的新型扁桃酸盐,其中R 1和R 2, 2个独立地为氢或C 1-6烷基,R 3和R 4各自独立地为氢或卤素。 在上述定义中,C 1-6烷基定义了具有1至6个碳原子的直链和支链饱和烃基,例如甲基,乙基,丙基,丁基,1-甲基丙基, 1-二甲基乙基,戊基或己基。 新颖的扁桃酸盐盐不敏感,并且在室温,升高的温度和相对高的湿度和水性介质中比现有技术的盐更稳定。 还公开了包含根据本发明的扁桃酸盐的药物组合物,根据本发明的用作药物的扁桃酸盐,根据本发明的扁桃酸盐的制备方法以及包含扁桃酸盐的扁桃酸盐和药物组合物的用途,所述扁桃酸盐包括扁桃酸盐 涉及用于治疗或预防CNS疾病,心血管疾病和胃肠道疾病的本发明。
