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.

In Vitro

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].

Stock Solution Working Solution

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.

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.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
