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.
帕金森病的治疗剂含有黄嘌呤衍生物或其药学上可接受的盐作为活性成分。黄嘌呤衍生物由以下式子表示:##STR1## 其中R.sup.1、R.sup.2和R.sup.3分别表示氢、低碳基、低烯基或低炔基;而R.sup.4表示环烷基、--(CH.sub.2).sub.n --R.sup.5(其中R.sup.5表示取代或未取代的芳基或取代或未取代的杂环基;n为0到4的整数),或##STR2## 其中Y.sup.1和Y.sup.2分别表示氢、卤素或低碳基;而Z表示取代或未取代的芳基,##STR3## 其中R.sup.6表示氢、羟基、低碳基、低烷氧基、卤素、硝基或氨基;m表示1到4的整数,或取代或未取代的杂环基;而X.sup.1和X.sup.2分别表示氧或硫。
