Compounds of the formula ##STR1## wherein one of the radicals R.sup.1, R.sup.2 or R.sup.3 denotes a straight-chain alkyl group having 4 to 8 C atoms and two vicinal hydroxyl groups in the .omega.,.omega.-1 or .omega.-1,.omega.-2 positions and the two other radicals represent straight-chain or branched alkyl groups having up to 12 C atoms in the position of R.sup.1 and R.sup.3 and up to 4 C atoms in the position of R.sup.2, the total of C atoms in these two alkyl substituents being a maximum of 14, are prepared by oxidation of the corresponding alkenylxanthines and by alkylation with compounds which introduce the dihydroxyalkyl radical or a precursor thereof. The dihydroxyalkyldialkylxanthines are suitable for the treatment of obstructive respiratory tract diseases.
化合物的式子为##STR1## 其中R.sup.1、R.sup.2或R.sup.3中的一个表示具有4到8个碳原子的直链烷基,并且在ω,ω-1或ω-1,ω-2位置具有两个邻位羟基,而另外两个基团在R.sup.1和R.sup.3的位置表示具有多达12个碳原子的直链或支链烷基,并且在R.sup.2的位置具有多达4个碳原子,这两个烷基取代物中的碳原子总数最多为14。通过对应的烯丙基黄嘌呤的氧化和烷基化,引入二羟基烷基基团或其前体,制备出二羟基烷基二烷基黄嘌呤。二羟基烷基二烷基黄嘌呤适用于治疗阻塞性呼吸道疾病。
