The invention relates to the use of one or more than one of the compounds of the general formula (I)
wherein R1 and R2 may be identical or different and, each independently of each other, represent hydrogen, hydroxy, amino, C1 to C10 alkyl, C1 to C10 alkoxy or C1 to C10 alkylamino, or R1 and R2, together with the carbon atom in position 4 of the pyrrolidinone ring, form a five- to ten-membered saturated or unsaturated ring which, besides the carbon atoms, may have up to 2 heteroatoms selected from oxygen, sulfur and nitrogen atoms, and which ring may be unsubstituted or substituted by up to 3 substituents selected from hydroxy groups, amino groups, C1 to C4 alkyl radicals, C1 to C4 alkoxy radicals and C1 to C4 alkylamino radicals, with the proviso that R1 and R2 are not both hydrogen; R3, R4, R5 and R6 may be identical or different and, each independently of each other, represent hydrogen, halogen, hydroxy, amino, C1 to C10 alkyl, C1 to C10 alkoxy, C1 to C10 alkylamino of C6 to C10 aryl; and R7 represents hydrogen, C1 to C10 alkyl or C1 to C10 acyl, and pharmaceutically acceptable salts thereof and/or prodrugs thereof for the manufacture of a medicament having an oxidation stress protection-promoting effect on mammalian cells.
本发明涉及一种或一种以上通式(I)化合物的用途
其中 R1 和 R2 可以相同或不同,并且各自独立地代表氢、羟基、氨基、C1 至 C10 烷基、C1 至 C10 烷氧基或 C1 至 C10 烷基氨基,或者 R1 和 R2 与吡咯烷酮环第 4 位上的碳原子一起形成一个五至十元饱和或不饱和环,该环除了碳原子外,还可以有多达两个选自氧、硫和氮原子的杂原子,并且该环可以是一个或多个五元或十元饱和或不饱和环、该环可以未被取代,也可以被最多 3 个选自羟基、氨基、C1 至 C4 烷基、C1 至 C4 烷氧基和 C1 至 C4 烷基氨基的取代基取代,但 R1 和 R2 不能都是氢;R3、R4、R5 和 R6 可以相同或不同,各自独立地代表氢、卤素、羟基、氨基、C1 至 C10 烷基、C1 至 C10 烷氧基、C6 至 C10 芳基的 C1 至 C10 烷基氨基;以及 R7 代表氢、C1 至 C10 烷基或 C1 至 C10酰基,及其药学上可接受的盐和/或其原药,用于制造对哺乳动物细胞具有氧化应激保护促进作用的药物。
