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
