(HCV). Metal ion chelators have achieved widespread success in the development of antiviral drugs. Some inhibitors with metal ion chelating structures have been proven to have good inhibitory activities on non-structural protein 5B (NS5B) polymerase. However, most of the reported metal ion chelators showed poor anti-HCV potency at the cellular level. Hence, we designed and synthesized a series of 3-
全世界有数百万人患有由丙型肝炎病毒 (HCV) 引起的急性或慢性肝脏炎症。金属离子螯合剂在抗病毒药物的开发中取得了广泛的成功。一些具有金属离子螯合结构的抑制剂已被证明对非结构蛋白5B(NS5B)聚合酶具有良好的抑制活性。然而,大多数报道的金属离子螯合剂在细胞水平上表现出较差的抗 HCV 效力。因此,我们设计合成了一系列具有新型金属离子螯合结构的3-羟基喹唑啉-2,4(1 H ,3 H )-二酮衍生物。典型化合物如21h、21k和21t显示出比利巴韦林更好的抗 HCV 活性,EC 为50值小于 10 μM。21t是目前已知的金属离子螯合剂之一,在细胞水平上具有最佳的抗 HCV 效力(EC 50 = 2.0 μM),并且与利巴韦林和报道的化合物6相比具有更好的治疗指数(TI > 25)。在热位移分析中,代表性化合物21e和21k提高了熔化温度 ( T m) NS5B 蛋白溶液在测试浓度下分别升高
Synthesis of Homoallylic Amines by Radical Allylation of Imines with Butadiene under Photoredox Catalysis
single electron (1 e−) mediated allylation of imines with butadiene and alkyl halides is reported. This operationally simple method provides efficient access to a broad range of structurally diverse homoallylic amines with exceptional functional-group compatibility.
