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 R
1
and R
2
each independently are hydrogen or C
1-6
alkyl and R
3
and R
4
each independently are hydrogen or halogen. In the foregoing definitions C
1-6
alkyl 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按照公式(I)定义的取代四环四氢呋喃衍生物的新型曼德酸盐,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烷基定义为具有1至6个碳原子的直链和支链饱和碳氢基基团,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,并且比先前的盐在室温,升高温度和相对高湿度以及在水介质中更加稳定。还披露了包括根据本发明的曼德酸盐的制药组合物,根据本发明的曼德酸盐作为药物的用途,制备根据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含曼德酸盐的制药组合物的用途。
