Description: Besifovir (formerly known as ANA-380; LB-80380; PMCDG dipivoxil; Korea Trade name: Besivo) is a reverse transcriptase inhibitor that has been approved in Korea to treat hepatitis B virus (HBV) infection. It is a novel and potent acyclic nucleotide phosphonate with a similar chemical structure to adefovir and tenofovir. Besifovir is a prodrug and an oral nucleotide analogue that inhibits viral replication by incorporation into the viral DNA. Antiviral activity against wild-type virus and virus with drug-resistant mutations was demonstrated in Phase II trials, with significant reduction of viral load in patients treated with LB80380. LB80380 was also shown to be safe and well tolerated.

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 add µL PEG300, mix and clarify, next add µL Tween 80,mix and clarify, next add µL ddH₂O,mix and clarify.

Note:

(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
