in the pentatomic NO-donor furoxan ring, as well as their structurally related furazan analogues devoid of NO-donating properties, are described. The whole series of products displayed reversible histamine H3-antagonistic activity on guinea-pig ileum. 4-(4-(3-(1H-Imidazol-4-yl)propoxy)phenyl)furoxan-3-carbonitrile 16 was also able to induce partial relaxation when added to the bath after electrical
描述了一系列化合物的合成和药理学表征,其中存在于吡虫啉中的肟亚结构被约束在五原子NO-供体呋喃环中,以及它们的结构相关呋喃类似物没有NO的提供特性。整个系列的产品对豚鼠回肠均表现出可逆的组胺H3拮抗活性。当在豚鼠回肠电收缩期间将4-(4-(3-(1H-咪唑-4-基)丙氧基)苯基)呋喃喃-3-甲腈16加入浴中时,也能够引起部分松弛。 H3拮抗性质的研究。这种现象似乎取决于NO介导的sGC活化。研究了所有产物的亲脂-亲水平衡。
