Using Ttou 84 as starting point, a novel class of biphenyl derivatives of imidazo[1,2-a]pyridine and imidazo[1,2-b]pyridazine was designed to optimize the inhibitory properties on the replication of the bovine viral diarrhoea virus (BVDV) and hepatitis C virus (HCV). Three sites of pharmacomodulation were chosen i.e. positions 2, 3 and 6 on the central heterocyclic core structure. From the 49 analogues
以Ttou 84为起点,设计了一类新型的咪唑并[1,2- a ]吡啶和咪唑并[1,2- b ]哒嗪联苯衍生物,以优化其对牛病毒性腹泻病毒复制的抑制作用( BVDV)和丙型肝炎病毒(HCV)。选择药物调节的三个位点,即中央杂环核心结构上的位置2、3和6。在测试的49个类似物中,只有化合物18j(3-(2'-hydroxybiphen-3-yl)-2-(2-甲氧基苯基)-6-(thien-3-yl)咪唑并[1,2- b ]哒嗪在HCV复制子系统中显示抗病毒活性,使人联想到选择性抑制(抑制60-70%)。化合物4f(3-(联苯-3-基)-2-(4-氟苯基)-6-苯硫基咪唑并[1,2- a吡啶]被证明是BVDV复制的最有选择性的抑制剂,与瘟病毒复制的已知抑制剂没有或仅有很小的交叉耐药性。4f的交叉电阻谱可能表明4f与BPIP,VP32947,AG110或LZ37没有与相同的结合位点相互作用。从针对
