Abstract

Nasopharyngeal carcinoma (NPC) is a distinctive epithelial cancer closely associated with Epstein-Barr Virus (EBV) infection, posing significant challenges in diagnosis and treatment due to its resistance to conventional therapies and high recurrence rates. Current therapies, including radiotherapy and chemotherapy, exhibit limited efficacy, particularly in recurrent or metastatic cases, highlighting the urgent need for novel therapeutic strategies. Targeting EBV oncoproteins, such as Epstein-Barr Virus encoded Nuclear Antigen 1 (EBNA1), Latent Membrane Protein 1 (LMP1), and Latent Membrane Protein 2 (LMP2), presents a promising therapeutic avenue in NPC treatment. This review discusses the latest advancements in drug discovery targeting EBV oncoproteins, emphasizing the identification of inhibitors for specific functional regions of oncoproteins EBNA1, LMP1, and LMP2. Particular attention is given to the molecular mechanisms of these inhibitors and their preclinical or clinical potential in treating EBV-positive NPC. These developments highlight a promising future for targeted therapies in improving outcomes for NPC patients.
