surface antigen [hepatitis b virus]

The nucleocapsid of the hepatitis B virus is covered by an envelope of HBV surface antigen (HBsAg), which has the common, group-specific determinant a. The four major subtypes of HBsAg, adw, adr, ayw and ayr, are generated, and they have been proposed to

HBF-0259 is an inhibitors of hepatitis B virus surface antigen (HBsAg) secretion with an EC50 of 11.3 μM and a CC50 value of >50 μM in HepG2.2.15 cells. HBF-0259 had a EC50 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.

AB-161 is an orally active destabilizer of HBV RNA and an inhibitor of PAPD5 7, primarily targeting the liver. It treats hepatitis B virus (HBV) infection by reducing hepatitis B surface antigen (HBsAg) levels, exhibiting an EC50 value of 2.2 nM for HBsAg. AB-161 is applicable in HBV infection research.

Destruxin B2 is a cyclic hexadepsipeptide mycotoxin that has been found in M. anisopliae and has antiviral, insecticidal, and phytotoxic activities.1,2,3 It inhibits secretion of hepatitis B virus surface antigen (HBsAg) by Hep3B cells expressing hepatitis B virus (HBV) DNA (IC50 = 1.3 μM).1 Destruxin B2 is toxic to Sf9 insect cells in an electric cell-substrate impedance sensing (ECIS) test with a 50% inhibitory concentration (ECIS50) value of 92 μM.4 It is also phytotoxic to B. napus leaves.3 |1.

Hepatitis B Virus Pre-S Region (120-145) is a preS2 peptide that effectively blocks the attachment of single-chain Fv fragment (scFv) or IgG to recombinant Hepatitis B surface antigen (r-HBsAg) [1].

HBV Seq2 aa:179-186, a novel epitope located on the hepatitis B virus surface antigen, effectively serves as a motif for CTL response within the H-2b system following in vitro restimulation of primed T cells [1].

Dihydrodehydrodiconiferyl alcohol 9-O-β-D-xylopyranoside serves as an anti-hepatitis B virus (anti-HBV) agent, effectively inhibiting the secretion of HBV surface antigen (HBsAg) and HBV e antigen (HBeAg) in the Hep G2.2.15 cell line, with IC50 values of 1.67 mM for HBsAg and over 2.15 mM for HBeAg [1].

Periglaucine A inhibits hepatitis B virus (HBV) surface antigen (HBsAg) secretion in Hep G2.2.15 cells.

Periglaucine B can inhibit hepatitis B virus (HBV) surface antigen (HBsAg) secretion in Hep G2.2.15 cells.
