formation. Related structures have also been investigated; homologues 4-[4-(3-(trifluoromethyl)phenoxy)butyl]-1H-imidazole and 4-[2-(3-(trifluoromethyl)phenylthio)ethyl]-1H-imidazole are shown to be partial agonists, whereas the O isostere 4-[2-(3-(trifluoromethyl)phenoxy)ethyl]-1H-imidazole is an antagonist as is the S homologue 4-[3-(3-(trifluoromethyl)phenylthio)propyl]-1H-imidazole and its CH(2) isostere
合成了4-(3-芳氧基丙基)-1H-咪唑类化合物,该化合物在芳基环中具有间位取代基,并测试了其对组胺H(3)受体的活性。发现具有CN,Me或Br取代基的化合物是拮抗剂,而经过测试,CF(3),Et,i-Pr,t-Bu,COCH(3)或NO(2)取代基可显着提供部分激动剂在大鼠脑皮层突触小体上体外抑制[(3)H]组胺的释放。这些化合物在体内也具有活性,此外,CF(3)取代的化合物trifluproxim(UCL 1470,7)作为体内有效的全效激动剂,其ED(50)= 0.6 +/- 0.3 mg / kg每抑制小鼠脑N(tau)-甲基组胺形成。相关结构也已被研究。
