of a previously reported series of analogous size and shape, thus suggesting a similar A(1)-binding mode. In particular, the binding data indicate that alkylation of the 4-amino group of these derivatives lead to potent A(1)-receptor antagonists. Moreover, as new results, this study has pointed out that the ethyl 2-carboxylate group can advantageously replace the 2-(hetero)aryl ring of previously reported
由于大多数已报道的腺苷受体拮抗剂是2-(杂)芳基取代的三环杂芳族衍生物,因此在本研究中,我们报道了一组新的4-氨基-1,2,4-三唑并合成和生物学评估[在位置2处含有羧酸乙酯基团或氢原子的1,5-a]喹喔啉。这些化合物的结构活性关系与先前报道的一系列类似的大小和形状一致,因此表明了相似的A(1)结合模式。特别地,结合数据表明这些衍生物的4-氨基的烷基化导致有效的A(1)-受体拮抗剂。此外,作为新的结果,该研究指出,2-羧酸乙酯基团可以有利地取代先前报道的三唑并喹喔啉衍生物的2-(杂)芳基环,
