(−)-(S)-3-(3′-hydroxy)-butylphthalide (a compound shown by Formula I) and an ester formed of the same and an acid are proved by experiments to be applicable to treatment and prevention of cerebral ischemic diseases and have a sleep-improving function. The acid refers to a pharmaceutically acceptable inorganic or organic acid. The inorganic acid refers to nitric acid, sulfuric acid, or phosphoric acid. In addition to an acid radical, the organic acid at least comprises at least one of an amino group, a hydroxyl group, and a carboxyl group. None of the compound shown by Formula I and the ester thereof is water-soluble. An ester generated from the compound and the acid further react with an acid or a base to generate a salt which is water-soluble and is used to prepare injection preparation. The experiment proves that the salt does not stimulate vessels.
(-)-(S)-3-(3'-羟基)-丁基邻苯二甲酸酯(化学式I所示的化合物)及其与酸形成的酯经实验证明可用于治疗和预防脑缺血性疾病,并具有改善睡眠的作用。酸指的是医药上可接受的无机或有机酸。无机酸指的是硝酸、硫酸或磷酸。除了酸基外,有机酸至少包括氨基、羟基和羧基中的至少一种。化学式I所示的化合物及其酯都不溶于水。从该化合物和酸生成的酯进一步与酸或碱反应生成水溶性盐,用于制备注射制剂。实验证明,该盐不会刺激血管。
