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.
本文披露了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、二甲氨基甲基或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独立地为氢或1至3个碳原子的烷基,且当3-取代基为氢时,4-取代基不为羟基或氢。这些化合物是具有相对较低脂溶性的强效腺苷受体拮抗剂,用于支气管扩张剂和心肌强效剂。
