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
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 Cmax levels fails to result in cellular or mitochondrial toxicity, and displays no DNA polymerase gamma inhibition.[1]
Cell Research 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.
In Vivo
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.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
