OM-7D3-B3
Based on 1 Customer Validation
OM-7D3-B3 is an antibody-based antiviral agent targeting the tight junction protein CLDN1 (Kd=4 nM). By binding to the first extracellular domain of CLDN1, OM-7D3-B3 disrupts the formation of the CLDN1-CD81 co-receptor complex, thereby effectively inhibiting the entry of hepatitis C virus (HCV). OM-7D3-B3 not only prevents de novo and chronic HCV infections in humanized liver chimeric mice and uPA-SCID mice transplanted with human livers, but also exhibits favorable safety with no toxic effects observed. OM-7D3-B3 serves as a critical tool for research on HCV infection mechanisms and antiviral drug development.

OM-7D3-B3 (20 μg/mL) specifically binds to CLDN1 on the surface of Huh7.5.1 cells, HepG2 cells, primary human hepatocytes, and 293T cells overexpressing CLDN1[1].
OM-7D3-B3 partially inhibits the entry of HCV pseudovirions (genotypes 1a and 1b) into primary human hepatocytes[1].
Serial dilutions of OM-7D3-B3 dose-dependently inhibit infection of Huh7.5.1 cells by wild-type and DAA-resistant HCVcc, with IC50 values of 0.13 μg/mL, 0.23 μg/mL, and 0.36 μg/mL against Jc1, Jc1-A156S, and Jc1-R155K, respectively[1].
OM-7D3-B3 (11 μg/mL; 24 h) effectively inhibits cell-to-cell transmission of HCV between Huh7.5.1 producer cells and target cells[1].
When used in combination with Sofosbuvir (HY-15005) and Daclatasvir (HY-10466), OM-7D3-B3 exhibits synergistic antiviral activity against HCVcc infection in Huh7.5.1 cells[1].
