The invention relates to novel eburnamenine derivatives of formula (I): ##STR1## wherein R.sup.1 and R.sup.2 as well as R.sup.3 and R.sup.4, independently from each other, stand for hydrogen, C.sub.2-6 alkyl group, C.sub.2-6 alkenyl group; or a C.sub.3-10 alicyclic group involving 1 to 3 rings, and this latter group may be substituted by a C.sub.1-6 alkyl or C.sub.2-6 alkenyl group; or R.sup.1 and R.sup.2 and/or R.sup.3 and R.sup.4, together with the adjacent nitrogen atom and optionally with an additional oxygen or nitrogen atom, form a 4- to 6-membered, saturated or unsaturated cyclic group which may be substituted by a C.sub.1-6 alkyl or C.sub.2-6 alkenyl group; two of X, Y and Z are nitrogen whereas the third of them means a methine group; n is 1 or 2; W means oxygen or two hydrogen atoms; and the wavy line means .alpha.-/.alpha.-, .alpha.-/.beta.- or .beta.-/.alpha.- steric position, as well as their acid addition salts and solvates. The invention further relates to pharmaceutical compositions containing the above compounds as well as a process for preparing the compounds of formula (I). The compounds of formula (I) possess antioxidant effect and therefore, they are useful for inhibiting the peroxidation of lipids occurring in mammals (including human).
该发明涉及式(I)的新型eburnamenine衍生物:其中R.sup.1和R.sup.2以及R.sup.3和R.sup.4,彼此独立地代表氢、C.sub.2-6烷基、C.sub.2-6烯基;或涉及1至3个环的C.sub.3-10脂环基,该后者可以被C.sub.1-6烷基或C.sub.2-6烯基基团取代;或者R.sup.1和R.sup.2和/或R.sup.3和R.sup.4,与相邻氮原子以及可选地与额外的氧原子或氮原子一起形成一个4到6元的饱和或不饱和环基团,该环基团可以被C.sub.1-6烷基或C.sub.2-6烯基基团取代;X、Y和Z中的两个是氮,第三个是甲基基团;n为1或2;W表示氧或两个氢原子;波浪线表示α-/α-、α-/β-或β-/α-立体位置,以及它们的酸盐和溶剂化合物。该发明还涉及含有上述化合物的药物组合物以及制备式(I)化合物的方法。式(I)化合物具有抗氧化作用,因此它们可用于抑制发生在哺乳动物(包括人类)中的脂质过氧化。
