| Research Abstract |
Epstein-Barr Virus (EBV) transforms human B lymphocytes into immortalized cells in vitro, and is associated with various malignancies in vivo. DNA-binding protein EBNA1 plays critical role for the viral episome maintenance and transactivates viral transforming genes in latently infected cells. Therefore, DNA-targeting agents that can disrupt the EBNA1-DNA interaction will offer novel functional inhibitors of EBNA1. Here, a synthetic pyrrole-imidazole polyamide bound adjacent to the EBNA1 recognition sequences located in the dyad symmetry element of oriP, and selectively inhibited EBNA1-oriP binding. This polyamide inhibited EBV-mediated B-cell immortalization. These results suggest that EBNA1 functions will be an attractive pharmacological target for EBV-associated diseases.
