    摘要: Novel xanthine compounds represented by the following formula: ##STR1## wherein each of X.sup.1 and X.sup.2 independently represents oxygen or sulfur; and Q represents; ##STR2## where ----- represents a single bond or a double bond; Y represents a single bond or alkylene, n represents 0 or 1, each of W.sup.1 and W.sup.2 independently represents hydrogen, lower alkyl or amino, Z represents --CH.sub.2 -, --O--, --S-- or --NH--; represents ##STR3## each of R.sup.1 and R.sup.2 independently represents hydrogen, lower alkyl, allyl or propargyl; and R.sup.3 represents hydrogen or lower alkyl, and when Q represents the groups other than ##STR4## each of R.sup.1, R.sup.2 and R.sup.3 independently represents hydrogen or lower alkyl;provided that when Q is ##STR5## then R.sup.1 R.sup.2 and R.sup.3 are notsimultaneously methyl; and pharmaceutically acceptable salts thereof have a diuretic effect, a renal-protecting effect and a bronchodilatory effect.

    摘要: A xanthine derivative of the formula (I): ##STR1## wherein R.sup.1 and R.sup.2 are the same or different and are substituted or unsubstituted alicyclic alkyl; m1 and m2 are the same or different and represent an integer of 0 to 2; and Q represents ##STR2## (in which R.sup.3 and R.sup.4 are the same or different and are substituted or unsubstituted alicyclic alkyl) or ##STR3## (in which n is 0 or 1, and Y is a single bond or alkylene); or a pharmaceutically acceptable salt thereof is disclosed.This derivative has diuretic activity and renal protecting activity.
