HBF-0259 | CAS#957011-15-3

MedKoo Cat#: 530621 | Name: HBF-0259

Description:

WARNING: This product is for research use only, not for human or veterinary use.

HBF-0259 is a novel inhibitors of hepatitis B virus surface antigen (HBsAg) secretion. HBF-0259 was identified to inhibit HBsAg with an EC50 of 11.3 μM and a CC50 value of >50 μM in HepG2.2.15 cells. HBF-0259 had a 50% effective concentration of approximately 1.5 microM in a secondary, HBV-expressing cell line, with a concentration that exhibited 50% cytotoxicity of >50 microM. The equilibrium concentration of HBF-0259 in aqueous solution at physiological pH was 15 to 16 microM; the selective index was thus >9.

More Info

The high levels of hepatitis B virus (HBV) surface antigen (HBsAg)-bearing subviral particles in the serum of chronically infected individuals play an important role in suppressing HBV-specific immune response and are only mildly affected by the current small molecule therapies.
