Twenty-five novel imidazole N–H substituted Daclatasvir (BMS-790052, DCV) analogues (8a–8y) were designed and synthesized as potential prodrugs. Structure modifications were performed in order to improve potency and pharmacokinetic (PK) properties. All target compounds were evaluated in a hepatitis C virus (HCV) genotype 1b replicon, and the 2-oxoethyl acetate substituted compound 8t showed similar
设计并合成了25种新型咪唑N–H取代的达卡他韦(BMS-790052,DCV)类似物(8a – 8y),并将其合成为潜在的前药。为了改善效能和药代动力学(PK)特性,进行了结构修饰。在丙型肝炎病毒(HCV)基因型1b复制子中评估了所有目标化合物,并且2-氧代乙酸乙酯取代的化合物8t显示出与 先导化合物Daclatasvir相似的抗HCV活性(EC 50 = 0.08 nM)。此外,前药8t的效用前体药物在体内给药时母体化合物的相似暴露证明了这一点。PK研究表明,前药8t是达拉他韦缓释和缓释形式的理想候选药物。
