CEF19, Epstein-Barr Virus latent NA-3A (458-466), is a peptide epitope, YPLHEQHGM, representing residues 458-466 of the type 1 Epstein-Barr Virus (EBV) nuclear antigen 3A protein (B95.8 strain).
3-Epicorosolic acid has a potent inhibitory effect on Epstein-Barr virus early antigen (EBV-EA) induction, it has potential anti-inflammatory activities as well as cancer chemopreventive activity.3-Epicorosolic acid shows both potent α-glucosidase and pro
β-Cembrenediol (β-CBT) is a natural product from tobacco plants that is found in cigarette smoke condensate. β-CBT inhibits induction of the early antigen of Epstein-Barr virus (EA-EBV) by 12-O-tetradecanoylphorbol-13-acetate (TPA) in vitro (IC50 = 21.9 μM). It inhibits tumor promoting effects of TPA on 7,12-demethylbenz[a]anthracene-induced papilloma formation in vivo. β-CBT is also released into soil by flue-cured tobacco plants and exerts autotoxicity as well as phytotoxic activity against L. sativa seedlings.
Multiflorenol is a triterpene that has been found in T. kirilowii seeds.1 It inhibits in vitro activation of Epstein-Barr virus early antigen (EBV-EA) induced by the tumor promoter phorbol 12-myristate 13-acetate in a concentration-dependent manner. |1.

9,13β-Epidioxy-8(14)-abieten-18-oic acid has anti-inflammatory activities, it exhibits moderate activities on NO levels in LPS-stimulated murine microglia BV2 cells, with IC50 values of 57.3 ± 0.2 uM. It is also a potential antitumor-promoting diterpenoid, it shows potent inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by the tumor promoter 12-O-tetradecanoylphorbol 13-acetate. 9 α ,13 β -Epidioxyabeit-8(14)en-18-oic acid may contribute to the growth inhibitory effect of the pine needles and may play an important role in the allelopathy of red pine.
L-I-OddU, a potent and selective anti-Epstein-Barr virus (EBV) agent, is a L-5'-halo-dioxolane nucleoside analogue. It demonstrates antiviral activity by effectively suppressing replicative EBV DNA and viral protein synthesis [1] [2]. With an EC 50 value of 0.03 μM, L-I-OddU exhibits high potency against EBV while maintaining low cytotoxicity, as indicated by its CC 50 value of 1000 nM.
