Abstract:BACKGROUND: Acorus calamus l. (Acoraceae)是一种众所周知的中国药用植物,其根源主要用于治疗神经退行性疾病和霍乱治疗。该基准强烈指示曲霉的抗菌活性。
方法: 乙醇提取了木薯的根。蚊子幼虫C6/36细胞用于DENV2复制和转染宿主。小鼠肾脏成纤维细胞(BHK-21)用作宿主细胞研究病毒的感染能力。 DENV2诱导的细胞质效应(CPE)和牙菌斑测定法用于评估鱿鱼提取物对DENV2感染性抑制的抑制作用。 The levels of E and NS1 protein expression were measured by real-time PCR and western blot assays.
RESULTS: 12 compounds were isolated from ethanol extract of A. calamus root, tatanan A showed the best anti-DENV ability among these 12 compounds, which significantly alleviated DENV2-induced CPE and细胞毒性效应,ECOF为3.9 µm。此外,RNA复制测定进一步证实了抗virus ability of tatanan A. Time-addition assay showed that tatanan A affected the early stage of viral RNA replication, which in turn inhibited mRNA and protein levels of DENV2.
CONCLUSIONS: These results demonstrated the anti-DENV2 effect of tatanan A, in inhibiting DENV2 RNA复制和感染。总而言之,发现塔塔南A是一种新型的天然DENV抑制剂,并且是治疗DENV传染病的潜在候选者。
