The preparation for preventing and curing organ dysfunctions, provided by the present invention, is a medicament having the activity to prevent and cure organ dysfunctions which active oxygen species and active organic radical species would cause, and unconventionally improved in stability in vivo by containing, as an active component, the ascorbic acid derivative of the formula, ##STR1## wherein R.sub.2 is a group selected from the class consisting of an alkylcarbonyl lower alkyl group of which the terminal alkyl group has 7 inclusive to 15 inclusive carbon atoms, an alkyl group having 9 inclusive to 17 inclusive alkyl groups and an alkoxycarbonyl lower alkyl group of which the terminal alkoxy group has 7 inclusive to 20 inclusive carbon atoms; and the ascorbic acid derivative of the above formula in which R.sub.2 is an alkylcarbonyl lower alkyl group of which the terminal alkyl group has 7 inclusive to 15 inclusive carbon atoms is novel and disclosed in the present specification together with the process for its preparation.
本发明提供的预防和治疗器官功能障碍的制剂是一种具有预防和治疗器官功能障碍活性氧物种和活性有机自由基物种引起的药物,并通过含有作为活性成分的抗坏血酸衍生物而在体内非常改善了稳定性,该抗坏血酸衍生物的结构式为:
其中R2是从以下类别中选择的一组,包括具有7个至15个碳原子的终端烷基的烷基羰基较低烷基基团,具有9个至17个碳原子的烷基基团和具有7个至20个碳原子的终端烷氧基的烷氧羰基较低烷基基团;以及上述结构式中R2为具有7个至15个碳原子的终端烷基的烷基羰基较低烷基基团的抗坏血酸衍生物是新颖的,并与其制备方法一起在本说明书中披露。
