Tertiary hydroxyalkylxanthines having the general formula (I), characterized by the fact that at least one of the residues R.sup.1 and R.sup.3 represents a tertiary hydroxyalkyl group of formula (Ia) in which R.sup.4 represents an alkyl group having up to 3 carbon atoms and n a whole number from 2 to 5; the other residue which may remain R.sup.1 or R.sup.3 is a hydrogen atom or an aliphatic hydrocarbon residue R.sup.5 having up to 6 carbon atoms, in which the carbon chain may be separated by a maximum of two oxygen atoms or be substituted by an oxo group or two hydroxy groups at the most, and R.sup.2 represents an alkyl group with 1 to 4 carbon atoms. Also described is a process for manufacturing these compounds, which are suitable for the manufacture of medicines, in particular for use in the prevention and/or treatment of peripheral and/or cerebral irrigation disorders. ##STR1##
具有通式(I)的三级羟基烷基黄嘌呤,其特征在于至少有一个残基R.sup.1和R.sup.3代表具有通式(Ia)的三级羟基烷基基团,其中R.sup.4代表具有2至5个碳原子的烷基基团,n为2至5的整数;另一个可能保留为R.sup.1或R.sup.3的残基是氢原子或具有最多6个碳原子的脂肪烃残基R.sup.5,其中碳链最多可以被最多两个氧原子分隔或被氧基团或最多两个羟基取代,R.sup.2代表具有1至4个碳原子的烷基基团。还描述了一种用于制造这些化合物的方法,这些化合物适用于药物制造,特别是用于预防和/或治疗外周和/或脑灌注障碍。
