- CAS No.: 2648009-64-5
- Formula:C485H618F9N158Na40O294P39S6
- Molecular Weight:14976.67
SMILES: [Elebsiran]
Biological Activity: Elebsiran (VIR-2218) is a siRNA that targets and degrades hepatitis B virus (HBV) and hepatitis D virus (HDV) RNA transcripts. Elebsiran leads to a significant decrease in HBV surface antigen (HBsAg) and a reduction in viral load. Elebsiran binds to the sialic acid-depleted glycoprotein receptor (ASGPR) on the surface of liver cells through the GalNAc ligand, achieving liver-targeted delivery and demonstrating improved liver safety. Elebsiran can be used for the study of chronic HBV/HDV infections[1][2][3].
