A series of Matijin-Su (MTS) derivatives were designed, synthesized and their anti-hepatitis B virus (HBV) activities were evaluated in vitro. Twelve compounds displayed good inhibitory activity against HBV DNA replication with IC values at micromolar level (0.14-4.81 µM), and among them, compounds 13d, 13n, and 13o were selected for further study. Compound 13d suppressed the HBeAg secretion with IC value of 2.57 µM (SI = 4.31), while had no effect on HBsAg. However, compounds 13n and 13o showed no effect to both HBeAg and HBsAg. The molecular docking studies indicated that compound 13d could form H-bond interaction with protein residues of HBV core protein which deserves further study.
设计并合成了一系列马替金 - 苏（MTS）衍生物，并在体外评估了它们的抗乙型肝炎病毒（HBV）活性。十二种化合物对HBV DNA复制显示出良好的抑制活性，IC值处于微摩尔水平（0.14 - 4.81 μM），其中化合物13d、13n和13o被选作进一步研究。化合物13d抑制HBeAg分泌，IC值为2.57 μM（SI = 4.31），而对HBsAg无影响。然而，化合物13n和13o对HBeAg和HBsAg均无影响。分子对接研究表明，化合物13d可与HBV核心蛋白的蛋白质残基形成氢键相互作用，值得进一步研究。
