Results PFs did not suppress HIV-1-mediated syncytium formation,however,they significantly increased the viabilities of HIV-1-infected cells and the inhibition rates of p24 antigen levels.Moreover,their effects arrived at the highest in the first trimester,and decreased along with the progress of pregnancy.

结果：各孕期PF并不能抑制MT2和H9/HIV-1 ⅢB细胞的融合，但可以增加HIV-1感染细胞的存活率及减少HIV-1 p24抗原的表达，且效应以早孕期PF最大，中孕期PF其次，晚孕期PF最小，并与剂量呈正相关。

Methods Calcein-AM stained H9/HIV-1 ⅢB cells were treated with difierent concentrations of PF in the first,second and third trimesters respectively,which was then mixed with MT2 cells and put under fluorescent microscopy for detection of HIV-1-mediated syncytium formation.MT2 cells were treated with cell-free HIV-1 Ⅲ B,and then washed and cultured with different concentrations of PF in the first,second and third trimesters respectively.Furthcrly,the protecting effect of PFs against HIV-1-infected cells Was determined with MTT,viral replication Was evaluated by measurement of the levels of p24 antigen in culture supernatants with ELISA and the inhibition rate Was calculated.

采用荧光染料Calcien-AM标记的H9/HIV-1 ⅢB分别与早、中、晚孕期不同稀释浓度的PF作用后，与MT2细胞混合培养，荧光显微镜下观察合胞体的形成；用游离的HIV-1 ⅢB感染MT2细胞，并分别与早、中、晚孕期不同稀释浓度的PF作用后，用MTT法检测HW-1感染细胞的存活率，用HIV-1 p24抗原试剂盒检测细胞培养上清中p24抗原含量的变化。

AIM: To isolate bioactive secondary metabolites from the fruits of Schisandra rebriflora Rehd. et. Wils and study their effects on HIV-1 infectivity. METHODS: Inhibition of syncytia formation, HIV-1 reverse transcriptase and protease, protection of HIV-1 infected cells, level of HIV-1 p24 antigen,blockage of fusion were detected. RESULTS: A lignan compound, named rubrifloralignan A, was first isolated as a natural product with modest inhibition effects on syncytium formation and HIV- 1 replication and could protect HIV-1 infected cells with weak inhibition effects on fusion and RT, but it showed no effects on the replication of HIV-1 chronic H9 and PR. CONCLUSION: Rubrifloralignan A is an efficient anti-HIV-1 product with effect on early stage of HIV-1 replication.

目的：从红花五味子果实中寻找活性代谢产物，研究其抗HIV—1活性和作用机制方法：通过合胞体抑制、HIV-1感染细胞保护、HIV—1p24抗原测定、融合阻断、逆转录酶和蛋白酶活性分析等实验，检测分离化合物的抗HIV—1活性并探讨其作用机制一结果：红花五味子甲素能够抑制病毒诱导的合胞体形成，保护病毒感染细胞，抑制病毒在细胞内的复制对HIV-1感染细胞与正常CD4^＋细胞间的融合，逆转录酶活性有一定的抑制作用但是红花五味子甲素不抑制病毒在慢性感染细胞中的复制，也不抑制蛋白酶的活性、结论：首次从天然产物中分离得到红花五味子甲素，它对HIV—1病毒复制早期具有抑制作用
