摘要: There is provided a novel xanthine Compound(I) ##STR1## wherein R.sup.1 and R.sup.2 are the same or different and each represent hydroxy-substituted, oxo-substituted or unsubstituted lower alkyl, Y is a single bond or alkylene, and Q is ##STR2## wherein R.sup.3 and R.sup.4 are the same or different and each represent hydrogen or hydroxy, n is 0 or 1; provided that when both of R.sup.3 and R.sup.4 are hydrogen, at least one of R.sup.1 and R.sup.2 is hydroxy-substituted or oxo-substituted lower alkyl; or a pharmaceutically acceptable salt thereof.The xanthine compound has adenosine A.sub.1 receptor antagonizing activity, and thus shows diuretic effect, renal-protecting effect, bronchodilatory effect, cerebral function improving effect and anti-dementia effect.
