12-Bromododecanoic acid, a halogenated derivative of lauric acid, serves in the synthesis of clickable myristic acid derivatives and functions as a model fatty acid ligand for elucidating the X-ray crystal structure of bovine β-lactoglobulin-ligand complexes. This compound, at a concentration of 10 µg ml, has been shown to diminish virion DNA in the culture supernatant of primary hepatocytes from a duckling model of hepatitis B virus (HBV) infection and exhibits inhibitory activity against HIV replication in CEM-SS T cells with an EC50 value of 38 µM.
HBV-IN-4, a derivative of phthalazinone, functions as a potent, orally active inhibitor of HBVDNA replication, exhibiting an IC50 value of 14 nM. It effectively induces the formation of genome-free capsids, demonstrating significant anti-HBV potency[1].
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.

ent-Entecavir is an enantiomeric impurity of the antiviral drug Entecavir. Entecavir is an oral antiviral drug used in the treatment of hepatitis B virus (HBV) infection. Entecavir is a reverse transcriptase inhibitor. It prevents the hepatitis B virus from multiplying and reduces the amount of virus in the body. More specifically, it is a deoxyguanosine analogue belonging to a class of carbocyclic nucleosides, that inhibits reverse transcription, DNA replication and transcription in the viral replication process.
HBV-IN-21 (Compound II-8b) is a potent inhibitor of HBVDNA replication, exhibiting an IC50 of 2.2 μM. It demonstrates a favorable binding affinity (K D = 60.0 μM) for the HBV 4 capsid protein, thereby enabling effective interaction [1].
