The anti-herpes simplex virus (HSV) compound, oxyresveratrol, purified from a Thai traditional medicinal plant of Artocarpus lakoocha, was evaluated for its anti-varicella-zoster virus (VZV) activity. This compound exhibited IC(50) values (50%-inhibitory concentrations for virus plaque formation) of 12.82, 12.80, 12.99 and 12.82 microg/ml against wild type, thymidine kinase-deficient and two types of DNA polymerase mutants with acyclovir-resistance, respectively. Thus oxyresveratrol showed a broad spectrum of anti-VZV activity with a mechanism of action different from that of acyclovir.
从泰国传统药用植物大叶桂木中提纯得到的抗单纯疱疹病毒（HSV）化合物氧化白藜芦醇，对其抗水痘带状疱疹病毒（VZV）活性进行了评估。该化合物对野生型、胸苷激酶缺陷型以及两种对阿昔洛韦耐药的DNA聚合酶突变型VZV的半数抑制浓度（IC50，即抑制病毒空斑形成的50%浓度）分别为12.82、12.80、12.99和12.82微克/毫升。因此，氧化白藜芦醇显示出广谱抗VZV活性，其作用机制与阿昔洛韦不同。
