The present invention designs and synthesizes ascorbyl ester derivatives of aryl (ethanoic) propanoic acid non-steroidal anti-inflammatory medicaments, such as ibuprofen, ketoprofen and naproxen, and addition salt of the derivatives with pharmaceutical acid or pharmaceutical alkali. The non-steroidal anti-inflammatory medicament which takes the ibuprofen as the representative is a common antipyretic analgesic medicament. The invention has remarkable antipyretic and analgesic effects and good safety except for anti-inflammatory effect, thus being not only suitable for adults, but also suitable for elderly people, infants and children. The aryl (ethanoic) propanoic acid ascorbyl ester can be converted into ascorbyl ester derivatives and the addition salts of the derivatives with pharmaceutical acid or pharmaceutical alkali, which can improve the water solubility thereof, facilitate intravenously administration, reduce the onset time, improve the bioavailability, reduce the stimulation effect to gastrointestinal tract, and enhance the penetrating capacity to hemato encephalic barrier, and can be used as a novel medicament to be applied for antiphlogistic, antipyresis, analgesia, treatment of arthritis, dysmenorrheal, multiple sclerosis, pneumonia cystic fibrosis and patent ductus arteriosus of premature infants, and prevention and treatment of cerebral apoplexy, hypoxic-ischemic brain damage, senile dementia and certain cancers.
本发明设计合成了布洛芬、酮洛芬、萘普生等芳基(乙)丙酸类非甾体抗炎药物的抗坏血酸酯衍生物,以及衍生物与药用酸或药用碱的加成盐。以布洛芬为代表的非甾体抗炎药物是一种常用的解热镇痛药物。本发明除消炎作用外,解热镇痛效果显著,安全性好,不仅适用于成人,也适用于老人、婴幼儿。芳基(乙)丙酸抗坏血酸酯可转化为抗坏血酸酯衍生物及衍生物与药用酸或药用碱的加成盐,可提高其水溶性,便于静脉给药,缩短起效时间,提高生物利用度,减少对胃肠道的刺激作用、可作为新型药物应用于抗抑郁、镇痛、治疗关节炎、痛经、多发性硬化、肺炎囊性纤维化和早产儿动脉导管未闭,以及预防和治疗脑中风、缺氧缺血性脑损伤、老年性痴呆和某些癌症。
