A drug effective in preventing and ameliorating dysfunctions of organs caused by active oxygen species and active organic radical species, comprising an ascorbic acid derivative of general formula (I) as the active ingredient in order to solve the problem of in vivo unstableness of conventional drugs, wherein R₂ represents a group selected from among alkylcarbonyl (lower alkyl) groups wherein the terminal alkyl group has 7 to 15 carbon atoms, alkyl groups having 9 to 17 carbon atoms, and alkoxycarbonyl (lower alkyl) groups wherein the terminal alkoxy group has 7 to 20 carbon atoms. Ascorbic acid derivatives of the above general formula, wherein R₂ represents an alkylcarbonyl (lower alkyl) group wherein the terminal alkyl group has 7 to 15 carbon atoms are new substances, and this invention discloses these new substances and a method of producing the same.
一种有效预防和改善由活性氧和活性有机自由基引起的器官功能障碍的药物,由通式(I)的抗坏血酸衍生物作为活性成分,以解决传统药物在体内不稳定的问题、其中 R₂ 代表选自烷基羰基(低级烷基)(其中末端烷基具有 7 至 15 个碳原子)、烷基(具有 9 至 17 个碳原子)和烷氧基羰基(低级烷基)(其中末端烷氧基具有 7 至 20 个碳原子)的基团。上述通式中,R₂代表烷基羰基(低级烷基),其中末端烷基具有 7 至 15 个碳原子的抗坏血酸衍生物是新物质,本发明公开了这些新物质及其生产方法。
