lpiperazin-1-yl)dibenzo[b,f][1,4]oxazepine), reported as a dual H1/H4 receptor ligand (pKi: 8.11 (human H1R (hH1R)), 7.55 (human H4R (hH4R))), four known and 28 new oxazepine and related oxepine derivatives were synthesised and pharmacologically characterized at histamine receptors and selected aminergic GPCRs. In contrast to the oxazepine series, within the oxepine series, the new compounds showed
受到VUF6884(7-Chloro-11-(4-methylpiperazin-1-yl)dibenzo [b,f] [1,4] oxazepine的启发),报道为双重H1 / H4受体配体(pKi:8.11(人H1R( hH1R)),7.55(人H4R(hH4R))),四种已知的和28种新的奥氮平及其相关的奥西平衍生物已合成,并在组胺受体和选定的胺能GPCR上进行了药理学表征。与奥氮平系列相反,在奥西平系列中,新化合物显示出对hH1R的高亲和力(pKi:6.8-8.7),但对hH4R的亲和力不高(pKi:≤5.3)。对于一种oxepine衍生物(1-(2-氯-6,11-二氢二苯并[b,e] oxepin-11-基] -4-甲基哌嗪),对映体被分离,R-对映体被鉴定为是对映体。 hH1R(pKi:8.83(R),7.63(S))和豚鼠H1R(gpH1R)(pKi:8.82(R),7.
