Description | Helioxanthin 8-1 is an analogue of helioxanthin, exhibites significant in vitro anti-HBV/HCV/HSV-1/HIV activity with EC50 of >5/10/1.4/15 uM.
IC50 value: >5/10/1.4/15 uM(HBV/HCV/HSV-1/HIV) [1]
Target: Antiviral agent
The cyclic hydrazide 28(Helioxanthin 8-1) showed the most potent antiHBV activity among those helioxanthin analogues tested. In addition, compound 28 exhibited moderately potent activity against HIV. It would therefore be promising to study helioxanthin analogues that contain a six-membered ring instead of the five-membered ring found in the lactam [1]. 8-1 exhibited effective inhibition on DHBV replication. The combination of 8-1 with 3TC resulted in additional anti-DHBV activity. Viral induced cells displayed higher susceptibility to 8-1 treatment than non-induced cells. HBV X protein might not be an essential factor in the initiation of the biological activity of 8-1, as demonstrated by its absence in DHBV [2]. References: |

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].

Helioxanthin analogue 8-1 inhibits duck hepatitis B virus replication in cell culture.[Pubmed:21107018]
Antivir Chem Chemother. 2010;21(2):97-103.
BACKGROUND: Current approved anti-HBV treatment cannot completely eliminate HBV infection, and emergence of resistant virus is an important treatment issue. Effective anti-HBV agents with different mechanisms of action on novel target sites are needed for the treatment of HBV infection and for combating the resistant virus, alone or in combination with current anti-HBV strategies. Helioxanthin analogue 8-1 displayed potent anti-HBV activity in human HBV in vitro and in animal models, with a unique antiviral mechanism. Its antiviral activity in other HBV system needs further study. METHODS: The anti-duck hepatitis B virus (DHBV) activity of 8-1, an analogue of a natural product, helioxanthin, was studied in the DHBV inducible cell line, dstet5, in comparison to and in combination with the nucleoside analogue, lamivudine (3TC). RESULTS: Helioxanthin analogue 8-1 exhibited anti-DHBV activity as demonstrated by quantification of viral DNA, RNA, covalently closed circular DNA and protein synthesis. Analogue 8-1 did not affect the stability of cellular macromolecules and did not have a sustained antiviral effect after drug removal. When DHBV replication was induced, virus-harbouring cells were more susceptible to the cytotoxicity of 8-1 than non-induced cells. CONCLUSIONS: 8-1 exhibited effective inhibition on DHBV replication. The combination of 8-1 with 3TC resulted in additional anti-DHBV activity. Viral induced cells displayed higher susceptibility to 8-1 treatment than non-induced cells. HBV X protein might not be an essential factor in the initiation of the biological activity of 8-1, as demonstrated by its absence in DHBV. These findings warrant further development of 8-1 for the treatment of chronic hepatitis B and its associated diseases.
