Use of xanthine derivatives for the treatment of nerve damage following an interruption in blood circulation. The invention relates to the use of xanthine derivatives of the formula I ##STR1## in which R.sup.2 is a (C.sub.1 -C.sub.4)-alkyl group and at least one of the symbols R.sup.1 and R.sup.3 is a radical of the formula II or III ##STR2## in which A is CHOH, CO or dioxolane, R.sup.4 is a hydrogen atom or a (C.sub.1 -C.sub.4)-alkyl group and n is 0 to 5, and in which R.sup.5 and R.sup.6 are hydrogen atoms or (C.sub.1 -C.sub.4)-alkyl groups or, together with the nitrogen atom to which they are bonded, form a 5- to 7-membered ring, it being possible for one carbon atom to be replaced by an oxygen or nitrogen atom, m is 1 or 2 and the other radical R.sup.1 or R.sup.3, if appropriate, is a hydrogen atom, a (C.sub.1 -C.sub.6)-alkyl group or a (C.sub.3 -C.sub.6)-alkenyl group, for the preparation of medicaments for the prophylaxis and treatment of nerve damage following an interruption in blood circulation, and novel xanthine derivatives, and to processes for their preparation.
对xanthine衍生物的使用,用于治疗由于血液循环中断而导致的神经损伤。该发明涉及使用公式I的xanthine衍生物##STR1##其中R.sup.2是(C.sub.1 -C.sub.4)-烷基基团,并且符号R.sup.1和R.sup.3中至少有一个是公式II或III的基团##STR2##其中A是CHOH、CO或二氧六环,R.sup.4是氢原子或(C.sub.1 -C.sub.4)-烷基基团,n为0至5,且R.sup.5和R.sup.6是氢原子或(C.sub.1 -C.sub.4)-烷基基团,或者与它们结合的氮原子一起形成5-到7-成员环,其中一个碳原子可以被氧原子或氮原子取代,m为1或2,另一个基团R.sup.1或R.sup.3,如果适用的话,是氢原子、(C.sub.1 -C.sub.6)-烷基基团或(C.sub.3 -C.sub.6)-烯基基团,用于制备用于预防和治疗由于血液循环中断而导致的神经损伤的药物,以及新型xanthine衍生物,以及它们的制备方法。
