    • This invention relates to pregnane anionic compounds of general formula I in which R1 is ester group, which is able to form ion such as sulfate, pyridinium sulfate, hemisuccinate etc., R2 is hydrogen atom in alpha or beta configuration, and R3 is ester group, as is acetoxy group, nicotinoyloxy group etc., and their pharmaceutically acceptable salts. Compounds of general formula I are preferably produced from the diol of formula II or diol of formula VIII, which are converted according to described sequence of reactions, to compounds of general formula I, in which R1 is ester group, which is able to form ion such as sulfate, pyridinium sulfate, hemisuccinate etc., R2 is hydrogen atom in alpha or beta configuration, and R3 is ester group. The compounds of general formula I are useful as active ingredients for production of pharmaceuticals for the treatment of neurological and psychiatric diseases and conditions associated with excessive activation of NMDA receptors such as neuroprotective agents against excitotoxic damage of the central nervous system (CNS), conditions associated with excessive activation of NMDA-subtype glutamate receptors or, where this type of receptor is involved in the creation or during the certain mental and neurological diseases, in particular concerning the traumatic and hypoxic damage Io nervous tissue in the central nervous system diseases, such as Alzheimer's, Huntington's and Parkinson's disease, also in cognitive disorders in aging; the other indications could be tardive dyskinesia, amyotrophic lateral sclerosis, olivopontocerebellar degeneration, neurological problems1 associated with AIDS infection, allergic encephalomyelitis, and for medication of epilepsy, anxiety, depression, schizophrenia, chronic pain and drug addiction.
    • 本发明涉及通式Ⅰ的孕烷阴离子化合物,其中R1为酯基,能够形成硫酸根离子,硫酸吡啶硫酸盐,半琥珀酸盐等,R2为α或β构型的氢原子,R3为酯基 ,如乙酰氧基,烟酰氧基等,及其药学上可接受的盐。 通式I的化合物优选由式II的二醇或根据所述反应顺序转化的式VIII的二醇制备成通式I的化合物,其中R1是酯基,其能够形成离子 如硫酸盐,硫酸吡啶鎓,半琥珀酸盐等,R2是α或β构型的氢原子,R3是酯基。 通式I的化合物可用作生产用于治疗神经和精神疾病的药物的活性成分,以及与NMDA受体过度激活相关的病症,例如针对中枢神经系统(CNS)的兴奋性毒性损伤的神经保护剂,与之相关的病症 NMDA亚型谷氨酸受体过度激活,或者这种类型的受体涉及创造或某些精神和神经疾病时,特别是关于中枢神经系统疾病中的神经组织的创伤性和缺氧性损伤,例如 老年痴呆症,亨廷顿病和帕金森病,也在老龄化认知障碍中; 其他适应症可能是迟发性运动障碍,肌萎缩性侧索硬化,橄榄体小脑变性,与艾滋病感染相关的神经问题1,过敏性脑脊髓炎,以及用于癫痫,焦虑,抑郁,精神分裂症,慢性疼痛和药物成瘾的药物。
