Helioxanthin 8-1, an analogue of helioxanthin (ACH126447), is an inhibitor of HBV and HIV virus with EC50 values of 0.03 μM and 2.7 μM, respectively [1].

Helioxanthin 8-1 is the cyclic hydrazide derivative of helioxanthin and has shown significant in vitro antivirus activity with EC50 values of 0.03 μM and 2.7 μM for HBV and HIV, respectively [1]. In the ds-tet5 cells, helioxanthin 8-1 can inhibit duck hepatitis B virus (DHBV) DNA synthesis with a mean IC50 value of 0.25±0.05 μM. Besides, in induced cells and non-induced ds-tet5 cells, helioxanthin 8-1 has cytotoxic effect with CC50 values of 18±2 μM and 45±3 μM, respectively, by using an MTT assay [2].
