Aloperine (1), a Chinese natural product with a unique endocyclic scaffold, was first identified to be a potent hepatitis C virus (HCV) inhibitor in our laboratory. Thirty-four new aloperine derivatives were designed, synthesized and evaluated for their anti-HCV activities taking 1 as the lead. Among them, compound 7f exhibited the potential potency with EC50 values in a micromolar range against both
Aloperine(1)是一种中国天然产物,具有独特的环内支架,在我们的实验室中首次被鉴定为有效的丙型肝炎病毒(HCV)抑制剂。以1为首,设计,合成和评估了34种新的苦瓜碱衍生物的抗HCV活性。其中,化合物7f对野生型和直接作用的抗病毒剂(DAA)耐药变体均表现出潜在的效价,其EC 50值在微摩尔范围内,并且与批准的DAA协同抑制HCV复制。此外,它还具有良好的口服药代动力学和安全性,表明其具有高度的类药物性质。主要机制表明7f可能针对宿主组件,与临床上当前使用的DAA明显不同。因此,我们认为苦参碱衍生物是一类新型的抗HCV药物,化合物7f已被选为有前途的抗病毒候选药物,用于进一步研究。
