Premedication with a combination of histamine H1 receptor (H1R) and H2 receptor (H2R) antagonists has been suggested as a prophylactic principle, for instance, in anaesthesia and surgery. Aiming at pharmacological hybrids combining H1R and H2R antagonistic activity, a series of cyanoguanidines 14–35 was synthesized by linking mepyramine-type H1R antagonist substructures with roxatidine-, tiotidine-
已建议将组胺 H1 受体 (H1R) 和 H2 受体 (H2R) 拮抗剂联合用药作为预防原则,例如在麻醉和手术中。针对结合 H1R 和 H2R 拮抗活性的药理杂种,通过将美吡胺型 H1R 拮抗剂亚结构与罗沙替丁、噻替替丁或雷尼替丁型 H2R 拮抗剂部分连接,合成了一系列氰基胍 14-35。N-去甲基美吡胺通过聚亚甲基间隔基连接到氰基胍基团,作为 H2R 拮抗剂部分的“尿素等价物”。针对分离的回肠 (H1R) 和分离的自发性搏动右心房 (H2R) 的组胺拮抗活性筛选标题化合物。结果表明,取决于 H2R 拮抗剂部分结构的性质,
