| Description | Brilliant Black BN (E 151) is an azo dye and a food colorant. It is a promising antiviral agent against EV71 infection via inhibiting the interaction between EV71 and its cellular uncoating factor cyclophilin A. |
| In vitro | Brilliant black BN在300 μM浓度下抑制了EV71-GFP的感染。Brilliant black BN表现出对EV71-GFP的剂量依赖性抑制，对感染的RD细胞中的EV71-GFP的 IC50 值为 10.1 μM。Brilliant black BN能够抑制所有测试的28种EV71、CVA16和CVA6毒株。在横纹肌肉瘤细胞中，染料E151对各种EV71毒株的50%抑制浓度范围从2.39 μM到28.12 μM，而其50%细胞毒性浓度为1870 μM [2]。 |
| In vivo | Brilliant black BN（i.p.；200 mg/kg；14天）在与PBS组比较时表现出轻微的病症，临床评分低于3，并随后恢复。所有E151 270处理的小鼠在整个实验过程中均完全受到保护[2]。 |
