AB-506 is a small-molecule inhibitor targeting HBV core protein, inhibits viral replication in vitro (IC50=77 nM).AB-506 binds to HBV core protein, accelerates capsid assembly and inhibits HBV pgRNA encapsidation.AB-506 blocks cccDNA establishment in HBV-infected HepG2-hNTCP-C4 cells and primary human hepatocytes, leading to inhibition of viral RNA, HBsAg, and HBeAg production (EC50=0.64-1.52 uM).AB-506 demonstrated activity across HBV genotypes A-H and maintains antiviral activity against nucleostide analog-resistant variants in vitro.AB-506 showed an 8 to 20-fold increase in EC50 values against L30F, L37Q, and I105T substitutions.AB-506 exhibits good oral bioavailability, systemic exposure, and higher liver to plasma ratios in rodents.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
