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.
本发明的对象是一种新型替代四环四氢呋喃衍生物的曼德酸盐,其化学式为(I),其中N-氧化物形式和立体化学异构体形式,其中R1和R2各自独立地为氢或C1-6烷基,R3和R4各自独立地为氢或卤素。在上述定义中,C1-6烷基定义为直链和支链饱和碳氢基团,其具有1至6个碳原子,例如,甲基,乙基,丙基,丁基,1-甲基丙基,1,1-二甲基乙基,戊基或己基。新型曼德酸盐不敏感于光,并且比室温下的现有盐稳定得多,在升高温度和相对高湿度以及水介质中也是如此。还公开了包括本发明的曼德酸盐的制药组合物,用于药物的曼德酸盐,制备本发明的曼德酸盐的过程以及用于治疗或预防中枢神经系统疾病,心血管疾病和胃肠疾病的曼德酸盐和包括曼德酸盐的制药组合物的用途。
