New xanthine compounds of the formula: ##STR1## in which: R.sub.1 is hydrogen or alkyl from C.sub.1 to C.sub.5 inclusive; R.sub.2 is a hydrocarbon radical up to C.sub.6 having optionally a double bond, phenyl or benzyl; R.sub.3 is hydrogen, alkyl, hydroxyalkyl or dihydroxyalkyl each from C.sub.1 to C.sub.5 R.sub.4 represents: ##STR2## in which: Y is hydrogen, halogen, alkyl or alkoxy from C.sub.1 to C.sub.5 or hydroxyl; Z is methylene or a straight or branched hydrocarbon radical from C.sub.2 to C.sub.5 optionally substituted by hydroxyl; and A is an amino group of the formula: ##STR3## p being 2 or 3; ##STR4## in which q is 1 or 2, and X is a single bond, oxygen or ##STR5## in which R.sub.5 is hydrogen, alkyl or alkylene up to C.sub.5, or ##STR6## in which m is an integer from 2 to 6 and R.sub.6 is alkyl from C.sub.1 to C.sub.5. These new compounds and physiologically tolerable acid addition salts thereof may be used as medicines especially in the treatment of all diseases where it is necessary to inhibit the antigenic antibody reactions.
新的黄嘌呤化合物的化学式为:##STR1## 其中:R.sub.1 是氢或碳原子数为1到5的烷基;R.sub.2 是碳原子数最多为6的烃基,可选地具有双键,苯基或苄基;R.sub.3 是氢、烷基、羟基烷基或二羟基烷基,每个烷基碳原子数为1到5。R.sub.4 代表:##STR2## 其中:Y 是氢、卤素、烷基或碳原子数为1到5的烷氧基或羟基;Z 是亚甲基或碳原子数为2到5的直链或支链烃基,可选地被羟基取代;A 是化学式为:##STR3## 的氨基团,p 为2或3;##STR4## 其中 q 为1或2,X 是单键、氧或##STR5## 其中 R.sub.5 是氢、烷基或碳原子数最多为5的烷基,或##STR6## 其中 m 是2到6的整数,R.sub.6 是碳原子数为1到5的烷基。这些新化合物及其生理耐受性酸盐可以用作药物,特别是在需要抑制抗原抗体反应的所有疾病的治疗中。
