  A Chemical Switch for the Modulation of the Functional Activity of Higher Homologues of Histamine on the Human Histamine H₃ Receptor:  Effect of Various Substitutions at the Primary Amino Function

  摘要：

  In ail effort to establish the structural requirements for agonism, neutral antagonism, and inverse agonism at the human histamine H-3 receptor (H3R) we have prepared a series of higher homologues of histamine in which the terminal nitrogen of the side chain has been either mono- or disubstituted with several aliphatic, alicyclic, and aromatic moieties or incorporated in cyclic systems. The novel ligands have been pharmacologically investigated in vitro for their affinities on the human H3R and H4R subtypes by radioligand displacement experiments and for their intrinsic H3R activities via a CRE-mediated P-galactosidase reporter gene assay. Subtle changes of the substitution pattern at the side chain nitrogen alter enormously the pharmacological activity of the ligands, resulting in a series of compounds with a wide spectrum of pharmacological activities. Among the several neutral H3R antagonists identified within this series, compounds 2b and 2h display an H3R affinity in the low nanomolar concentration range (pK(i) values of 8.1 and 8.4, respectively). A very potent and selective H3R agonist (1l, pEC(50) 8.9, alpha = 0.94) and a very potent, though not highly selective, H3R inverse agonist (2k, pIC(50) = 8-9, alpha -0.97) have been identified as well.

  histamine H(3) receptor agonists imbutamine or immepip with non-basic alcohol or hydrocarbon moieties. All compounds in this study show a moderate to high affinity for the cloned human H(3) receptor and, unexpectedly, almost all of them act as potent agonists. Moreover, in the alcohol series, we consistently observed an increased selectivity for the human H(3) receptor over the human H(4) receptor, but none

  在这项研究中，我们用非碱性醇或烃基团取代了已知的组胺H（3）受体激动剂imbutamine或immepip的基本胺功能。在这项研究中的所有化合物显示出对克隆的人类H（3）受体的中等至高亲和力，而且出乎意料的是，几乎所有化合物都充当有效的激动剂。此外，在酒精系列中，我们始终观察到对人类H（3）受体的选择性高于人类H（4）受体，但与它们的烷基胺同类物相比，该系列中的任何化合物都不具有增加的亲和力和功能活性。在这个新的化合物系列中，VUF5657 5-（1H-咪唑-4-基）-戊-1--1-醇是最有效的组胺H（3）受体激动剂（pK（i）= 8.0和pEC（50）= 8.1）在人类H（3）受体上的选择性是人类H（4）受体的320倍。

  omega-(1H-imidazol-4-yl)alkane-1-sulfonamides were prepared and found to be potent histamine H-3 receptor antagonists. High receptor affinity and a low difference in the data between the bioassays were achieved with 5-(1H-imidazol-4-yl)pentane-1-sulfonic acid 4-chlorobenzylamide (16). Good in vitro profiles were also obtained for 2-hydroxysulfonamide and vinylsulfonamide analogues. This complements and completes the existing set of imidazole-based sulfonamides and sulfamides.
