Agents for the treatment of Parkinson's disease contain, as an active ingredient, a xanthine derivative or a pharmaceutically acceptable salt thereof. The xanthine derivative is represented by the formula: ##STR1## in which R.sup.1, R.sup.2 are R.sup.3 are independently hydrogen, lower alkyl, lower alkenyl, or lower alkynyl; and R.sup.4 represents cycloalkyl, --(CH.sub.2).sub.n --R.sup.5 (in which R.sup.5 represents substituted or unsubstituted aryl or a substituted or unsubstituted heterocyclic group; and n is an integer of 0 to 4), or ##STR2## in which Y.sup.1 and Y.sup.2 represent independently hydrogen, halogen, or lower alkyl; and Z represents substituted or unsubstituted aryl, ##STR3## in which R.sup.6 represents hydrogen, hydroxy, lower alkyl, lower alkoxy, halogen, nitro, or amino; and m represents an integer of 1 to 4, or a substituted or unsubstituted heterocyclic group; and X.sup.1 and X.sup.2 represent independently O or S.
治疗帕金森病的药剂,其活性成分是一种黄嘌呤衍生物或其药物可接受的盐。该黄嘌呤衍生物的化学公式如下:##STR1## 其中,R.sup.1、R.sup.2和R.sup.3独立地代表氢、低级烷基、低级烯基或低级炔基;R.sup.4代表环烷基、--(CH.sub.2).sub.n --R.sup.5(其中R.sup.5代表取代或未取代的芳基或取代或未取代的杂环族;n是0到4之间的整数),或##STR2## 其中,Y.sup.1和Y.sup.2独立地代表氢、卤素或低级烷基;Z代表取代或未取代的芳基,##STR3## 其中,R.sup.6代表氢、羟基、低级烷基、低级烷氧基、卤素、硝基或氨基;m代表1到4之间的整数,或取代或未取代的杂环族;X.sup.1和X.sup.2独立地代表氧或硫。
