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 是有效的乙型肝炎病毒 表面抗原分泌选择性抑制剂，在 HepG2.2.15 细胞中的 EC50为 1.5 μM。

AB-161 是一种口服有效的HBV RNA去稳定剂和PAPD5 7抑制剂，主要作用于肝脏。通过降低乙型肝炎表面抗原 (HBsAg) 水平，AB-161 用于治疗乙型肝炎病毒 (HBV) 感染，其对HBsAg的EC50值为2.2 nM。AB-161 可用于HBV感染的研究领域。

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) 是一种 preS2 肽，可抑制单链 Fv 片段 (scFv) 或IgG 与 r-HBsAg 的结合。

HBVSeq2 aa:179-186 作为 H-2b 系统中 CTL 反应的有效基序，能在体外再刺激致敏 T 细胞后发挥作用，同时被认为是鉴定乙型肝炎病毒表面抗原的新表位。

Dihydrodehydrodiconiferyl alcohol 9-O-β-D-xylopyranoside 作为一种抗HBV剂，在Hep G2.2.15细胞系上能够抑制HBsAg和HBeAg的分泌，其IC50值分别约为1.67 mM和>2.15 mM。
