Description

Bulevirtide (Myrcludex B) is a NTCP inhibitor, a linear lipopeptide of 47 amino acids. Bulevirtide inhibits HBV and HDV entry into liver cells, blocks HBV infection in hepatocytes, and participates in HBV transcriptional suppression. Bulevirtide can be used in HDV infection and compensated cirrhosis research[1][2].

In Vitro

Bulevirtide (200 nM, 24 h) inihibits NTCP through non-covalent binding in a time- and dose-dependent manner, transfer to a newly synthesized NTCP molecule[3].
Bulevirtide (Huh7-NTCP cells, 2 μM, 9 days) exhibits potential antiviral activity as replication inhibitor, which blocks upregulation of NTCP mediated-HBV replication in Huh7-NTCP cells [5].

In Vivo

Bulevirtide (2 μg/g, s.c. for everyday) prevents HBV spreading from infected human hepatocytes in uPA/SCID mice, hinders amplification of the cccDNA pool in initially infected hepatocytes[4].
Bulevirtide (2 μg/g/d, s.c. for 3 weeks) blocks HBV cell entry in uPA/SCID mice through addressing the hepatocyte component rather than affecting virion productivity within the infected hepatocyte or the half-life of these cells[4].
Bulevirtide (5 μg,s.c., twice a day for 4 days) blocks upregulation of NTCP mediated-HBV replication in C57BL/6 mice as a replication inhibitor[5].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.5 mg/mL (0.46 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (0.46 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
