BA-53038B is an HBV core protein allosteric modulator (CpAM), binding to the HAP pocket and modulating HBV capsid assembly in a distinct manner (EC50: 3.32 μM).
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
SAMT-247 is an HIV inhibitor that acts by modifying the nucleocapsid NCp7 region of Gag in infected cells and blocking Gag processing and reducing infectivity.
SARS-CoV-2-IN-17 (Compound 16) is a highly effective inhibitor of SARS-CoV-2 nucleocapsid protein (NPro). It demonstrates potent anti-viral activity, with an EC50 value of 2.18 μM. Furthermore, SARS-CoV-2-IN-17 binds to NPro with a low Kd value of 7.82 μM, highlighting its potency as a NPro ligand [1].
Claficapavir (A1752) is a potent nucleocapsid protein (NC) inhibitor that effectively binds the HIV-1 NC with a dissociation constant (Kd) of 20 nM, resulting in the inhibition of its chaperone properties. This specific molecular interaction leads to strong antiviral activity against HIV-1, with an IC50 of approximately 1 μM [1].
