The compounds of the following formula:
1
wherein R, R
2
, R
3
and A have the meanings given in the specification, are endowed with selective A
3
adenosine receptor antagonist activity. These compounds can be used in a pharmaceutical composition to treat disorders caused by excessive activation of the A
3
receptor, or can be used in a diagnostic application to determine the relative binding of other compounds to the A
3
receptor. The compounds can be labeled, for example with fluorescent or radiolabels, and the labels used in vivo or in vitro to determine the presence of tumor cells which possess a high concentration of adenosine A
3
receptors.
具有以下公式的化合物:其中R、R2、R3和A具有规范中给定的含义,具有选择性A3腺苷受体拮抗活性。这些化合物可以用于制备药物组合物,用于治疗由A3受体过度激活引起的疾病,也可以用于诊断应用,以确定其他化合物与A3受体的相对结合。这些化合物可以被标记,例如用荧光标记或放射性标记,并且这些标记可以在体内或体外用于确定具有高浓度腺苷A3受体的肿瘤细胞的存在。
