    • The invention provides a superoxide dismutase derivative of the general formula[SOD][Z]wherein [SOD] represents a superoxide dismutase having 1 to 22 or 24 groups each derived from an amino groups by removal of one hydrogen atom in lieu of amino groups; [Z] represents a monovalent copolymer group, constituting units of which are a group of the formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 each represents a hydrogen atom or a residue derived by a removal of a hydroxyl group from an alkanol of 1 to 8 carbon atoms, an ethylene glycol monoalkyl ether containing an alkyl moiety of 1 to 4 carbon atoms or a glycerin dialkyl ether containing alkyl moieties of 1 to 4 carbon atoms, provided that either R.sup.1 or R.sup.2 and either R.sup.3 or R.sup.4 each represents a hydrogen atom, and a residue derived from the group of the above-mentioned formula by removal of OR.sup.1, OR.sup.2, OR.sup.3 or OR.sup.4 group from one of its COOR.sup.1, COOR.sup.2, COOR.sup.3 and COOR.sup.4 groups (where the bond on the carbon atom of the carbonyl group is attached to [SOD]), said monovalent copolymer group having an average molecular weight of 500 to 200,000; and n represents an integer of 1 to 22 or 24 corresponding to the number of said groups each derived from an amino group by removal of one hydrogen atom in said [SOD], or a pharmaceutically acceptable salt thereof. There also is provided a method for producing the above derivative and salt. The invention is further directed to medicinal uses and pharmaceutical compositions for oral administration.
    • 本发明提供了一种通式[SOD] [Z]的超氧化物歧化酶衍生物,其中[SOD]代表通过除去一个氢原子代替氨基,每个衍生自氨基的具有1至22个或24个基团的超氧化物歧化酶; [Z]表示单价共聚物基团,其构成单元为式“IMAGE”的基团,其中R 1,R 2,R 3和R 4各自表示氢原子或通过从烷醇中除去羟基而得到的残基 1至8个碳原子的烷基部分,含有1至4个碳原子的烷基部分的乙二醇单烷基醚或含有1至4个碳原子的烷基部分的甘油二烷基醚,条件是R 1或R 2以及R 3或R 4各自表示 氢原子和衍生自上述式的基团的残基,通过从其COOR1,COOR2,COOR3和COOR4基团之一除去OR1,OR2,OR3或OR4基团(其中羰基的碳原子上的键 所述单价共聚物基团的平均分子量为500〜200,000; n表示通过除去所述[SOD]中的一个氢原子而衍生自氨基的所述基团的数目的1-22或24的整数或其药学上可接受的盐。 还提供了制备上述衍生物和盐的方法。 本发明进一步涉及药物用途和用于口服给药的药物组合物。
