A set of 56 8-phenylxanthines, previously tested for adenosine antagonism (adenosine A1 receptor affinity), was analyzed by quantitative structure-activity relationship (QSAR) techniques. The resulting QSAR revealed that (1) the most potent receptor binders had already been made in this series and thus suggested the termination of synthesis of compounds with additional phenyl substituents to increase
通过定量结构-活性关系(QSAR)技术分析了一组先前测试过的腺苷拮抗作用(腺苷A1受体亲和力)的56种8-苯基黄嘌呤。最终的QSAR结果表明,(1)该系列中最有效的受体结合剂已经制成,因此,建议终止具有附加苯基取代基的化合物的合成以增加效力,并且(2)效力受到邻位变化的强烈影响比对苯基取代。在这项研究的基础上,合成了另外20种化合物,这些化合物主要含有旨在提高水溶性的对位取代基。所得磺酰胺衍生物之间保持了高效力(如QSAR所预测),并且水溶性大大提高。此外,
