1,3-alkylsubstituted-8-(3,4-,3- or 4-substituted phenyl)xanthines and pharmaceutically acceptable salts of such compounds are disclosed. The 3-substituents are hydrogen, dimethylaminomethyl, or 2,3-dihydroxypropyloxy. The 4-substituents are selected from hydroxy, cyano, --NHCON(R.sub.5).sub.2, --C(.dbd.NH)N(R.sub.5).sub.2, --NH--C(.dbd.NH)N(R.sub.5).sub.2, with each R.sub.5 independently being hydrogen or an alkyl group of one to three carbons and provided that when the 3-substituent is hydrogen the 4-substituent is not hydroxy or hydrogen. The compounds are potent adenosine receptor antagonists having relatively low lipophilicity. The compounds are intended for use as bronchodilators and cardiotonics.
本发明揭示了1,3-烷基取代-8-(3,4-,3-或4-取代苯基)黄嘌呤及其药学上可接受的盐。其中,3-取代基为氢、二甲氨甲基或2,3-二羟基丙氧基,4-取代基选自羟基、氰基、--NHCON(R.sub.5).sub.2、--C(.dbd.NH)N(R.sub.5).sub.2、--NH--C(.dbd.NH)N(R.sub.5).sub.2,其中每个R.sub.5都独立地为氢或一个碳数为1至3的烷基,且当3-取代基为氢时,4-取代基不为羟基或氢。这些化合物是有效的腺苷受体拮抗剂,具有相对较低的亲脂性。这些化合物用于治疗支气管扩张和心脏强心剂。
