the 3‐amino‐1‐propanol moiety common to the many previously described non‐imidazole H3 ligands. Detailed structure‐activity studies revealed that 1‐(2‐benzofuranylmethyl)‐ 5c (pA2 = 8.47 ± 0.05) and 1‐(3‐benzofuranylmethyl)‐4‐[5‐(N‐methyl‐N‐propyl)pentyloxy]piperidine 5d (pA2 = 8.15 ± 0.07) exhibit high potency for the H3 histamine receptor. In addition, the potency of selected 1‐[(N‐substituted‐N‐
已经制备了新型有效的非咪唑组胺H 3受体拮抗剂,并作为H 3受体拮抗剂(豚鼠空肠的电诱发收缩)进行了体外测试。本发明的化合物含有一个4-羟基哌啶核心,其作用是先前描述的许多非咪唑H 3配体所共有的3-氨基-1-丙醇部分的构象受限形式。详细的结构活性研究表明,1-(2-苯并呋喃基甲基)-5c(pA 2 = 8.47±0.05)和1-(3-苯并呋喃基甲基)-4- [5-(N-甲基-N-丙基)戊氧基]哌啶5天(pA 2 = 8.15±0.07)对H 3组胺受体表现出高效力。此外,还评估了选定的1-[((N-取代-N-甲基)-3-丙氧基] -5-(N-甲基-N-丙基)戊二胺作为H 3组胺受体拮抗剂的效能。引脚7和5c的4-羟基哌啶被高度柔性的3-(甲基氨基)丙氧基链取代后,化合物6a(pA 2 = 8.02)和6b(pA 2 = 6.23)的效力比哌啶类似物高和低(7,pA 2 = 7.79;
