In this study, the piperidine ring of immepip and its analogues was replaced by a rigid heterocyclic pyridine ring. Many compounds in the series exhibit high affinity and agonist activity at the human histamine H(3) receptor. Particularly, the 4-pyridinyl analogue of immepip (1c, immethridine) is identified as a novel potent and highly selective histamine H(3) receptor agonist (pK(i) = 9.07, pEC(50)
在这项研究中,immepip及其类似物的哌啶环被刚性杂环吡啶环取代。该系列中的许多化合物在人类组胺H(3)受体上表现出高亲和力和激动剂活性。特别是,immepip(1c,immethridine)的4-吡啶基类似物被确定为一种新型的有效且高度选择性的组胺H(3)受体激动剂(pK(i)= 9.07,pEC(50)= 9.74),具有300倍的折叠率密切相关的H(4)受体的选择性。
