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.
式为##STR1##的化合物,其中R.sup.1、R.sup.2或R.sup.3中的一个代表具有4至8个碳原子的直链烷基基团,且在.ω.、.ω.-1或.ω.-1、.ω.-2位置具有两个邻位羟基基团,而另外两个基团代表在R.sup.1和R.sup.3位置具有长链或支链烷基基团,碳原子数最多为12,在R.sup.2位置最多为4个碳原子,这两个烷基取代物中碳原子的总数最大为14,通过氧化相应的烯基黄嘌呤和使用引入二羟基烷基基团或其前体的化合物进行烷基化制备。二羟基烷基二烷基黄嘌呤适用于治疗梗阻性呼吸道疾病。
