Bulevirtide, also known by its developmental code name Myrcludex B, is a synthetic lipopeptide inhibitor of the sodium taurocholate cotransporting polypeptide (NTCP) that effectively inhibits the cellular entry of both hepatitis B virus (HBV) and hepatitis D virus (HDV) into hepatocytes, even in cases of compensated cirrhosis, showing significant potential for the treatment of chronic hepatitis D.

| In vitro | Bulevirtide (2 μM, 9 days) treatment of Huh7-NTCP cells exhibits antiviral activity by inhibiting viral replication and blocking NTCP-mediated upregulation of HBV replication in Huh7-NTCP cells.[3] |
| In vivo | Methods: Bulevirtide (2.5 mg/kg, subcutaneous injection, 100 mg/kg) was administered to OATP1a/1b-deficient mice to investigate the plasma bile acid dynamics after Bulevirtide inhibited NTCP. Results: Peak plasma bile salt concentrations were achieved 4 hours after Bulevirtide administration (Figure 1A), at which time most Bulevirtide had been cleared from the circulation. [2] |
