The effect of 1-beta-D-arabinofuranosylthymine (ara-T) on cell growth and synthesis of Epstein-Barr virus (EBV) in human lymphoblastoid cell lines was determined. The growth of P3HR-1 cells was not inhibited by 1 microgram of the drug per ml; however, infectious virus production was strongly inhibited and was accompanied by decreased expression of early antigen (EA) and viral capsid antigen (VCA). The ability of 12-O-tetradecanoylphorbol-13-acetate or n-butyric acid to induce synthesis of VCA, but not EA, in P3HR-1 cells was inhibited by ara-T. Similarly, VCA synthesis but not EA synthesis was inhibited by ara-T in Jijoye cells superinfected with the P3HR-1 strain of EBV. The results suggest that ara-T has a specific inhibitory action against EBV replication.
测定了1-β-D-阿拉伯呋喃糖基胸腺嘧啶(ara-T)对人淋巴母细胞系中细胞生长及爱泼斯坦-巴尔病毒(EBV)合成的影响。每毫升含1微克该药物时,P3HR-1细胞的生长未受抑制;然而,传染性病毒的产生受到强烈抑制,并伴有早期抗原(EA)和病毒衣壳抗原(VCA)表达的降低。ara-T抑制了12-O-十四酰佛波醇-13-乙酸酯或正丁酸在P3HR-1细胞中诱导VCA合成的能力,但不影响EA的合成。同样,ara-T抑制了感染EBV P3HR-1株的Jijoye细胞中VCA的合成,但不影响EA的合成。结果表明ara-T对EBV复制具有特异性抑制作用。
