  Synthesis of hemslecin A derivatives: A new class of hepatitis B virus inhibitors

  摘要：

  A series of hemslecin A derivatives were synthesized and evaluated for their anti-hepatitis B virus (HBV) activities, namely, inhibiting the secretion of hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg), and HBV DNA replication on HepG 2.2.15 cells. Most of the derivatives showed enhanced anti-HBV activities, of which compounds A1-A7, B5, C and E exhibited significant activities inhibiting HBV DNA replication with IC50 values of 2.8-11.6 mu M, comparable to that of the positive control, tenofovir. Compounds A1-A3, A5, B5, and C displayed low cytotoxicities, which resulted in high SI values of 89.7, 55.6, 77.8, >83.4, >55.8, and >150.5, respectively.
