摘要: 本文应用牛免疫缺陷病毒(BIV)合胞体形成和BIV长末端重复序列(LTR)引导的萤火虫荧光素酶(Luc)基因表达分析, 建立了抗艾滋病(AIDS)药物的筛选和评价模型。BIV合胞体形成及BIV-LTR引导的Luc基因活力与BIV感染的细胞呈线性关系。临床有效药物3'-叠氮胸嘧啶脱氧核苷(AZT)可显著抑制BIV合胞体的形成及BIV-LTR引导的Luc基因表大家水平, 并有剂量依赖关系。上述两种分得到AZTIC50分别为0.240.052 mmol/L

Abstract: The assays for bovine immunodeficiency virus (BIV) induced syncytium formation and BIV long terminal repeat (LTR) directed luciferase (Luc) gene expression were applied to screen and evaluate anti AIDS drugs. Frequency of the syncytium formation and BIV LTR directed Luc activity were in proportion to the number of input BIV infected cells. AZT inhibited the syncytium formation and the BIV LTR directed Luc gene expression level. Its inhibitory effects were dosedependent with the IC50 being 0.24 and 0.052 mmol/L, respectively.
