  New Analogs of Burimamide as Potent and Selective Histamine H3 Receptor Antagonists: The Effect of Chain Length Variation of the Alkyl Spacer and Modifications of the N-Thiourea Substituent

  摘要：

  Burimamide was one of the first compounds reported to antagonize the activation of the histamine H-3 receptor by histamine. We have prepared a large series of burimamide analogs by variation of the alkyl spacer length of burimamide from two methylene groups to six methylene groups and also by replacement of the N-methyl group with other alkyl and aryl groups. All analogs are reversible, competitive H-3 antagonists as determined on the guinea pig intestine. Elongation of the alkyl chain from an ethylene chain to a hexylene chain results in an increase of the H-3 antagonistic activity. The H-3 selective pentylene and hexylene analogs of burimamide are about 10 times more potent than burimamide. The N-thiourea substituents, however, have no beneficial influence on the affinity.
