• 產品描述： Helioxanthin derivative 5-4-2 is an analogue of helioxanthin, exhibits significant in vitro anti-HBV activity (EC50: 0.08 μM in HepG2.2.15 cells).

• 靶點： HBV

• 體外研究：
  Helioxanthin derivative 5-4-2 had potent anti-HBV activities in HepG2.2.15 cells, with the EC50s of 1 and 0.08 microM, respectively. The lamivudine-resistant HBV, L526M/M550V double mutant strain, was also sensitive to helioxanthin and 5-4-2. This class of compounds not only inhibited HBV DNA but also decreased HBV mRNA and HBV protein expression. The EC50 of HBV DNA inhibition was consistent with the EC50 of HBV 3.5 Kb transcript inhibition, which was 1 and 0.09 microM for helioxanthin and 5-4-2 respectively.
