Novel ethyl 2-(5-aryl-1H-imidazol-1-yl)-acetates 17 and propionates 18, together with their acetic acid 19 and acetohydrazide 20 derivatives, were designed and synthesized using TosMIC chemistry. Biological evaluation of these newly synthesized scaffolds in the HIV-1 Vpu- Host BST-2 ELISA assay identified seven hits (17a, 17b, 17c, 17g, 18a, 20f and 20g) with greater than 50% inhibitory activity. These
使用TosMIC化学方法设计和合成了新型的2-(5-芳基-1H-咪唑-1-基)乙酸乙酯17和丙酸酯18以及它们的乙酸19和乙酰肼20衍生物。在HIV-1 Vpu-Host BST-2 ELISA分析中对这些新合成的支架进行了生物学评估,鉴定出具有抑制活性大于50%的7个基因(17a,17b,17c,17g,18a,20f和20g)。这些命中已在HIV-1 Vpu-Host BST-2 AlphaScreen™中得到验证,发现七个化合物中的六个具有与ELISA分析相当的抑制活性百分比。在两种测定中具有一致百分比抑制活性的化合物17b和20g在剂量响应AlphaScreen™测定中的IC50值分别为11.6±1.1μM和17.6±0.9μM。在基于细胞的HIV-1抗病毒测定中,化合物17b的EC50 = 6.3±0。在无毒浓度下(CC50 = 184.5±0.8μM)为7μM,而化合物20g的抗病毒活性大致相当于其毒性(CC50
