  Synthesis and pharmacological evaluation of highly potent dual histamine H2 and gastrin receptor antagonists

  摘要：

  The chemical modification of the dual histamine H-2 and gastrin receptor antagonists described in our preceding paper, particularly the modification of spacers as well as the alteration of their connecting bonds at the gastrin receptor antagonist site (GA) from the amide bond to the carbamate bond, significantly improved not only their dual activity but also the GA versus CCK-A receptor selectivity.

  Synthesis and Biological Evaluation of a New Reversely Linked Type of Dual Histamine H2 and Gastrin Receptor Antagonist.

  摘要：

  为了提高先前报道的双重组胺H2和胃泌素受体拮抗剂的低口服吸收性，合成并评估了一类不同类型的化合物的生物活性。这些新的化合物以一种反转的方式，即头对头的方式，连接一个组胺H2受体拮抗剂（H2A）药效团部分和一个胃泌素受体拮抗剂（GA）药效团部分，这与先前报道的头对尾方式不同。这些新的杂化化合物分为三种类型：I型，常规酰胺型具有roxatidine部分；II型，反转酰胺型具有roxatidine部分；III型，直接连接famotidine部分和GA部分，不含间隔基的杂化化合物。其中，只有(R)-1-[3-(N'-{4-[2-(N-氨基磺酰基氨基)乙硫甲基]噻唑-2-基}胍甲基)苯基]-3-(1-甲基-2-氧-5-苯基-2,3-二氢-1H-1,4-苯并二氮杂卓-3-基)脲（42），属于III型，显示出微弱的但明显的组胺H2受体拮抗活性以及适度的胃泌素受体拮抗活性。最重要的是，发现这种化合物由于结构变化，包括分子量的降低，显示出了微弱但明显改善的体内口服抗胃酸分泌活性。

  In an attempt to improve the low oral absorbability of previously reported dual histamine H2 and gastrin receptor antagonists, compounds of a different type were synthesized and evaluated for biological activity. These new compounds bear a histamine H2 receptor antagonist (H2A) pharmacophore moiety attached to a gastrin receptor antagonist (GA) pharmacophore moiety in a reversed manner, namely the head-to-head manner, different from the previously reported head-to-tail manner. These new hybrid compounds were classified into three types : type I, the regular amide type bearing a roxatidine moiety; type II, the reversed amide type bearing a roxatidine moiety; and type III, hybrid compounds bearing a famotidine moiety directly connected to a GA moiety without a spacer. Among them, only (R)-1-[3-(N'-4-[2-(N-aminosulfonylamidino)ethylthiomethyl]thiazol-2-yl}guanidinomethyl)phenyl]-3-(1-methyl-2-oxo-5-phenyl-2, 3-dihydro-1H-1, 4-benzodiazepin-3-yl)urea (42), belonging to type III, showed a weak but distinct histamine H2 receptor-antagonistic activity as well as a modest gastrin receptor-antagonistic activity. Of most importance was the finding that this compound showed a weak but clearly improved in vivo oral antigastric acid secretory activity as a result of the structural changes, including the decreased molecular weight.
