In vivo (Add solvents to the product individually and in order)

Clear solution	5% DMSO 1 95% Corn oil	0.34mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 6.8 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	2.75mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 55 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description	Entecavir(BMS200475,SQ34676), a new deoxyguanine nucleoside analogue, is a selective inhibitor of the replication of the hepatitis B virus (HBV).
In vitro	For treatment of hepatitis B virus, combinations of ETV with each of the other HBV NRTI antivirals, adefovir, tenofovir, and lamivudine at 10 times their respective C^max levels fails to result in cellular or mitochondrial toxicity, and displays no DNA polymerase gamma inhibition.^[1]
In vivo	Treatment with Entecavir in combination with AIC649, Induces tightly regulated Immunological and virological responses during active and maintenance ereatment in the woodchuck model of chronic hepatitis B.

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines HepG2 cells Concentrations 0.034 - 3.4 μM Incubation Time 15 days Method HepG2 cells (2.7 × 10₆) are seeded onto collagen I-coated T75 flasks. Cultures are exposed to compounds for a total of 15 days, reseeding every 5 days to the original cell density. In addition, media and compounds are also replaced 3 days after seeding. This schedule results in replacement of media containing fresh compound on days 1, 3, 5, 8, 10, and 13. Cells and culture supernatants are harvested and assayed on days 5, 10, and 15.
