on newly developed phenylpiperazine derivatives of aromatic methylhydantoin differing in mutual positions of methyl and phenyl moieties. The new compounds were synthesized using Bucherer–Bergs reaction, two-phase alkylation, Mitsunobu reaction and/or an alkylation under microwave irradiation. The compounds developed were assessed on their affinity for serotoninergic receptors 5-HT1A, 5-HT6, 5-HT7 and
当前的研究集中在新开发的芳族甲基乙内酰脲的苯基哌嗪衍生物,其甲基和苯基部分的相互位置不同。这些新化合物是通过Bucherer-Bergs反应,两相烷基化,Mitsunobu反应和/或微波辐射下的烷基化反应合成的。开发的化合物在其亲和力被评定为血清素受体5-HT 1A,5-HT 6,5-HT 7,α 1个在放射性配体结合测定-ARs。选择的化合物在人类上的抑制作用测试5-HT 3A中所表示的爪蟾卵母细胞,以及对它们的活性在α 1-肾上腺素受体亚型分别在功能和电生理生物测定中。研究最多的化合物均显示出亲和力α 1 -ARs,5-HT 1A,5-HT 7(ķ我 〜0.8-353 nm)的比对5-HT显著更高6个受体。在5-HT非常弱的抑制效果3A在α伴随着高活性1D,观察选择的代表性化合物-AR亚型。在当前系列中,特别是5-(4-氟苯基)-3-(2-羟基-3-(4-(2-甲氧基苯基)哌嗪-1-基)丙基)-5-甲基咪唑烷-2
