Technical Support

Helioxanthin 8-1(Helioxanthin analogue 8-1) is an anti-HBV agent. Helioxanthin 8-1 exhibits anti-hepatitis B virus activity in both in vitro human hepatitis B virus models and animal models. Helioxanthin 8-1 inhibits the synthesis of duck hepatitis B virus (DHBV) DNA, covalently closed circular DNA, RNA and proteins, thereby blocking DHBV replication. Helioxanthin 8-1 shows higher cytotoxicity in virus-induced cells than in non-induced cells. Helioxanthin 8-1 can be used in studies related to hepatitis B virus infection.

体外実験

Helioxanthin 8-1 (0.1-3 μM; 6 days) potently inhibits DHBV replication in induced dstet5 cells, with an IC₅₀ value of 0.25 μM against viral DNA, 0.1 μM against viral RNA, and 0.1 μM against core protein. It also reduces cccDNA levels in a dose-dependent manner^[1].
Helioxanthin 8-1 (0.03-0.3 μM; 6 days, in combination with 3TC) exhibits additive anti-DHBV activity in dstet5 cells when used in combination with 3TC (HY-B0250). Enhanced viral DNA inhibition is observed across the combined concentration range, with a CI value of 0.82^[1].
Helioxanthin 8-1 (10-50 μM; 3 days) exhibits higher cytotoxicity towards virus-induced dstet5 cells (CC₅₀ = 18 μM) than towards uninduced dstet5 cells (CC₅₀ = 45 μM)^[1].
Helioxanthin 8-1 (100 μM; 48 h) reduces the viability of Vero cells (ATCC CCL-81) to 70.6%, with a CC₅₀ value of >100 μM^[2].

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1 mg/mL (2.66 mM); Clear solution

This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1 mg/mL (2.66 mM); Clear solution

This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
