| | Bepirovirsensodium Usage And Synthesis |
| Uses | Bepirovirsen (ISIS 505358) sodium is an antisense oligonucleotide targeting all HBV messenger RNAs. Bepirovirsen sodium leads to reductions in HBV-derived RNAs, HBV DNA and viral proteins. Bepirovirsen sodium can be used for the research of chronic HBV infection. Bepirovirsen sodium binding site sequence (GCACTTCGCTTCACCTCTGC)[1][2][3]. | | in vivo | Bepirovirsen sodium (22 and 50 mg/kg, s.c., twice weekly for week 1 and once weekly for weeks 2-4) reduces hepatic RNA transcripts, subsequent production of HBV DNA, and associated HBV serum antigens in HBV-transgenic mice[3].
| Animal Model: | HBV-transgenic mice[3] | | Dosage: | 22 and 50 mg/kg | | Administration: | s.c., twice weekly for week 1 and once weekly for weeks 2-4 | | Result: | Dose-dependently reduced hepatic expression of HBV RNA in HBV transgenic mice and reduced levels of all cytoplasmic hepatitis B core antigen in HBV-transgenic mice. |
